Why Geneticists get touchy about Epigenetics

Disclaimer: I am not a geneticist. For those of you who are new here, this is basically a genetics fan blog. I am trying to learn about genetics, and you know what?

Genetics is complicated.

I fully admit that here’s a lot of stuff that I don’t know yet, nor fully understand.

Luckily for me, there are a few genetics basics that are easy enough to understand that even a middle school student can master them:

  1. “Evolution” is the theory that species change over time due to some individuals within them being better at getting food, reproducing, etc., than other individuals, and thereby passing on their superior traits to their children.
  2. “Genes,” (or “DNA,”) are the biological code for all life, and the physical mechanism by which traits are passed down from parent to child.
  3. “Mendel squares” work for modeling the inheritance of simple traits
  4. More complicated trait are modeled with more complicated math
  5. Lamarckism doesn’t work.

Lamarck was a naturalist who, in the days before genes were discovered, theorized that creatures could pass on “acquired” characteristics. For example, an animal with a relatively normal neck in an area with tall trees might stretch its neck in order to reach the tastiest leaves, and then pass on this longer-neck to its children, who would also stretch their necks and then pass on the trait to their children, until you get giraffes.

A fellow with similar ideas, Lysenko, was a Soviet Scientist who thought he could make strains of cold-tolerant wheat simply by exposing wheat kernels to the cold.

We have the luxury of thinking that Lysenko’s ideas sound silly. The Soviet peasants had to actually try to grow his wheat, and scientists who pointed out that this was nonsense got sent to the gulag.

The problem with Lamarckism is that it doesn’t work. You can’t make wheat grow in Antarctica by sticking it in your freezer for a few months and animals don’t have taller babies just because you stretch their necks.

So what does this have to do with epigenetics?

Pop science articles talk about epigenetics as if it were Lamarckism. Through the magic of epigenetic markers, acquired traits can supposedly be passed down to one’s children and grandchildren, infinitely.

Actual epigenetics, as scientists actually study it, is a real and interesting field. But the effects of epigenetic changes are not so large and permanent as to substantially change most of the way we model genetic inheritance.

Why?

Epigenetics is, in essence, part of how you learn. Suppose you play a disturbing noise every time a mouse smells cherries. Pretty soon, the mouse would learn to associate “fear” and “cherry smell,” and according to Wikipedia, this gets encoded at the epigenetic level. Great, the mouse has learned to be afraid of cherries.

If these epigenetic traits get passed on to the mouse’s children–I am not convinced this is possible but let’s assume it is–then those children can inherit their mother’s fear of cherries.

This is pretty neat, but people take it too far when they assume that as a result, the mouse’s fear will persist over many generations, and that you have essentially just bred a new, cherry-fearing strain of mice.

You, see, you learn new things all the time. So do mice. Your epigenetics therefore keep changing throughout your life. The older you are, the more your epigenetics have changed since you were born. This is why even identical twins differ in small ways from each other. Sooner or later, the young mice will figure out that there isn’t actually any reason to be afraid of cherries, and they’ll stop being afraid.

If people were actually the multi-generational heirs of their ancestors’ trauma, pretty much everyone in the world would be affected, because we all have at least one ancestor who endured some kind of horrors in their life. The entire continent of Europe should be a PTSD basket case due to WWI, WWII, and the Depression.

Thankfully, this is not what we see.

Epigenetics has some real and very interesting effects, but it’s not Lamarckism 2.0.

Anthropology Friday: In the Shadow of Man, (4/5)

jane-van-lawick-goodall-in-the-shadow-of-man-book-coverHello! Today we are continuing with our discussion of Jane Goodall’s In the Shadow of Man, featuring the adventures of a family (or several families) of chimpanzees from The Gombe Stream National Park, Tanzania. Today’s focus is on social structure.

Social status:

“I began to suspect that Goliath might be the highest-ranking male chimpanzee in the area–and later I found that this was in reality the case. If William and Goliath started to move toward the same banana at the same time, it was William who gave way and Goliath who took the fruit. If Goliath met another adult male along a narrow forest track, he continued–the other stepped aside. Goliath was nearly always the first to be greeted when a newcomer climbed into a fig tree to join a feeding group of chimpanzees. One day I actually saw him driving another chimp from her nest to take it for himself. …

William, with his long scarred upper lip and drooping lower lip, was one of the more subordinate males in his relationships with other chimpanzees. If another adult male made signs of aggression toward him, William was quick to approach with gestures of appeasement and submission, reaching out to lay his hands on the other, crouching with soft panting grunts in front of the higher-ranking individuals. … When I offered him a banana in my hand for the first time, he stared at it for several moments, gently shook a branch in his frustration, and then sat uttering soft whimpering sounds until I relented and put the fruit on the ground. …

“Even in those days, Flo looked very old. … We soon found out that her character by no means matched her appearance: she was aggressive, tough as nails, and easily the most dominant of all the females at that time.

“Flo’s personality will become more vivid if I contrast it with that of another old female, Olly … was remarkably different. Flo for the most part was relaxed in her relations with the adult males; often I saw her grooming in a close group with with two or three males out in the forest, and in camp she showed no hesitation in joining David or Goliath to beg for a share of cardboard or bananas. Olly, on the other hand, was tense and nervous in her relations with others of her kind. She was particularly apprehensive when in close proximity to adult males, and her hoarse, frenzied pant-grunts rose to near hysteria if high-ranking Goliath approached her. …

“Olly tended to avoid large groups of chimps and often wandered around with only her two year old daughter Gilka for company.

EvX: Gilka eventually became so lonely and isolated that she made friends with a baboon:

“One day when Gilka was again waiting while Olly fished for termites, I heard a baboon bark further down the valley. At the sound Gilka’s whole attitude underwent and immediate change. [from her previously depresesed state.] …

“A moment later I saw Gilka move out from the trees, and at almost the same time a small baboon detached itself from the troop and cantered toward her. … the two ran up to each other, and for a moment I saw their faces very close together. Each had one arm around the other. The next moment they were playing, wrestling, and patting each other. Goblina went around behind Gilka and, reaching forward, seemed to tickle the chimpanzee in the ribs. Gilka, leaning back, pushed at Goblina’s hands, her mouth open in a wide smile. …

“I watched Gilka and Goblina playing for ten minutes, and all the time they were amazingly gentle. Then the baboon troop started to move on and Goblina scampered after it.”

EvX: Olly may have been avoiding other chimps because she was lower status, and being around people of higher status than oneself is often unpleasant.

“Often, too, Olly and Flo traveled about together in the forests, and all four children were playmates of long standing. For the most part, the relationship between Olly and Flo was peaceful enough, but if there was a single banana lying on the ground between them the relative social status of each was made clear: Flo had only to put a few of her moth-eaten hairs on end for Olly to retreat, pant-grunting and grinning in submission. …

Fifi the chimpanzee, image from Jane Goodall's website

“The adult females of the chimpanzee community are almost always submissive to the adult males, and and to many of the older adolescent males. But they have their own dominance hierarchy, of which Flo was for many years supreme. … Flo was exceptionally aggressive toward her own sex, and she would tolerate no insubordination from young adolescent males. Much of her confidence no doubt resulted from the fact that he was so often accompanied by her two eldest sons,and with the aggressive Fifi as well, the family was formidable indeed.”

EvX: Flo and Olly once they teamed up and literally beat the shit out of a strange female who had ventured into their territory. Perhaps not coincidentally, Flo was the most sexually popular female in the group.

As Jane observed the chimps over the decades, most of them received names that started with the same letter as their mothers. (It is usually difficult to know which chimp was an infant’s father.) So Flo is the matriarch of the “F-family.” According to Wikipedia:

The F-family has produced at least four alpha males for the community, and the matriarch, Flo, played a particularly important role in acknowledging Dr Goodall’s acceptance as a human observer by the community. The G-family has produced at least one alpha male, and also the birth of several twins, which are rare among chimpanzees. There are other families as well which include the T-family and S-family (which has produced one alpha male).

In other words, Flo’s children and grandchildren did very well for themselves. If you were a male chimp in the Gombe, you would want to mate with Flo.

The Wikipedia also tells us about the lives of some of the chimps born after the book ends, such as Frodo, Flo’s grandson:

Frodo (June 30, 1976 – November 10, 2013) was Fifi’s second oldest son.[39] His father was the relatively low-ranking male Sherry. Even from a young age, Frodo was large and aggressive. He learned to throw rocks as a juvenile, sometimes throwing them at and hitting and bruising his human observers.[40] As an adult, he was one of the largest chimpanzees ever observed in the community, at about 113 pounds (51 kg) and remained aggressive.[37][39] He also became an excellent hunter of red colobus monkeys, and was also able to intimidate other chimpanzees into sharing their kills with him if he was unsuccessful.[22][41] His large size and aggressive nature allowed him to attain high status…

As alpha male, Frodo maintained his position largely through intimidation.[22][37][41] He rarely groomed other males, and often demanded that other males groom him.[22][37][41] Frodo maintained his alpha position until becoming ill himself in 2002.[22][33][41][42] He was then defeated by a coalition of several males and spent most of the next two years on his own recovering from his wounds and illness.[22][33][41][42]

Frodo’s aggression was not limited to Colobus monkeys and other chimpanzees. In May 2002, he killed a 14-month-old human baby that the niece of a member of the research team had carried into his territory.[43] … In 1988, he attacked cartoonist Gary Larson, leaving him bruised and scratched.[43] In 1989, he attacked Goodall, beating her head to the point of nearly breaking her neck.[43]

Frodo fathered at least eight infants, second most of any group male (Wilkie fathered ten).

Perhaps if Frodo’s father had been high-status, he could have solidified his position via grooming and social coalition rather than violence, and thus perhaps avoided being violently deposed.

The entry on Wilkie notes his very different approach to dominance:

In 1989 Wilkie defeated Goblin and attained the alpha position.[53] Wilkie, attained this position despite being one of the smallest males in the community, at 37 kilograms (82 lb).[85] According to researchers at the University of Minnesota‘s Jane Goodall Institute Center for Primate Studies, Wilkie attained his position primarily by becoming popular by obsessively grooming other males.[79][85] Unlike most males, Wilkie also groomed females.[85] Wilkie also made effective use of charging displays.[79]

Mike’s rise:

“Mike‘s rise to the number-one spot in the chimpanzee hierarchy was both interesting and spectacular. In 1963, Mike had ranked almost bottom in the adult male dominance hierarchy. He… had been threatened and actually attacked by almost every other adult male. …

“A group of five adult males, including to-ranking Goliath, David Graybeard, and the huge Rodolf, were grooming each other. The session had been going on for some twenty minutes. Mike was sitting about thirty yards apart from them, frequently staring toward the group, occasionally idly grooming himself.

“All at once, Mike calmly walked over to our tent and picked up an empty kerosene can by the handle. Then he picked up a second can and, walking upright, returned to the place where he had been sitting. … After a few minutes he began to rock from side to side. … his hair slowly began to stand erect, and then, softly at first, he began a series of pant-hoots. … suddenly he was off, charging toward the group of males, hitting the two cans ahead of him. The cans, along with Mike’s crescendo of hooting, made the most appaling racket: no wonder the erstwhile peaceful males rushed out of the way. …

“Mike set off again, but he made straight for Goliath–and even he hastened out of the way like the others. Then mike stopped and sat, all his hair on end, breathing hard. …

“Rodolf was the first of the males to approach Mike, uttering soft pant-grunts of submission, crouching low and pressing his lips to Mike’s thigh. Next he began to groom Mike. … Finally David Greybeard went over to Mike, laid one hand on his groin, and joined in the grooming. Only Goliath kept away, sitting alone and staring toward Mike.”

EvX: So Mike becomes dominant.

“… it was fully another year before Mike seemed to feel quite secure in his position. He continued to display very frequently and vigorously, and lower-ranking chimps had increasing reason to fear him, since often he would attack a female or youngster viciously at the slightest provocation.”

The observance of human customs:

“Christmas that year at the Gombe Stream was a day to remember. I bought an extra large supply of bananas and put them around a small tree I had decorated with silver paper and absorbent cotton. Goliath and William arrived together on Christmas morning and gave loud screams of excitement when they saw the huge pile of fruit. They flung their arms around one another and Goliath kept patting William on his wide open screaming mouth while William laid one arm over Goliath’s back. Finally they calmed down and began their feast, still uttering small squeaks and grunts of pleasure.”

Friendship:

“Firm friendships, like that between Goliath and David Graybeard, seem to be particularly prevalent among male chimpanzees. Mike and the irascible, testy old J.B. traveled about in the same group very frequently. … The only two adult females we know of who enjoyed this kind of friendship were almost certainly sisters.”

EvX: J.B. uses his relationship with newly ascended Mike to raise his own social status and get more bananas.

Illness and Death:

“Shortly after Christmas, I had to leave the Gombe stream myself for another term at Cambridge. My last two weeks were sad, for William fell ill. … When he climbed down in the morning I saw that every few moments his body shook with violent spasms of shivering. … One morning, two days before I had to leave, William stole a blanket from Dominic’s tent. [Dominic was the camp cook.] He had been sitting chewing on it for a while when David Greybeard arrived and, after eating some bananas, joined William at the blanket. For half an hour or so the two sat peacefully side by side, each sucking noisily and contentedly on different corners. Then William, like the clown he so often appeared to be, put part of the blanket right over his head and made groping movements with his hands as he tried to touch David from within the strange darkness he had created. … Presently the two wandered off into the forest together, leaving me with the echo of a dry, hacking cough and the blanket lying on the ground. I never saw William again. …

To be continued…

 

 

LoL at “anti-racists” who move to all white neighborhoods “for the schools”

“Blacks are great!” they proclaim. “I just don’t want my kids to ever interact with one.”

Today we’re talking about school myths:

1. The schools are failing.

“The schools are failing” is a political talking point, a scare tactic designed to drum up votes. It bears little relation to reality.

If you are reading this, then chances are someone taught you to read, and that person was probably a public school teacher.

People come from all over the world to study at American universities; few Americans scatter abroad to study at other countries’ universities.

Our economy has, for the past century or so, been among the most advanced in the world. We’ve created or contributed significantly to the development of cars, airplanes, atomic bombs, computers, vaccines, etc. Oh, and we PUT A MAN ON THE MOON.

And everyone who worked on space program (immigrants excluded) started attending US schools back around 1910-1940. (I suspect our schools have gotten better since then.)

People make a big deal out of US students not scoring #1 in the world in international-comparison tests. What of it? There are lots of countries with smart people in them, and we can’t all be first.

But even granting this, the reports of American under-performance are massively overstated. Let’s compare the 2009 Programme for International Student Assessment (PISA) reading scores for the US and 64 other countries (graph thanks to Steve Sailer, who spent two days combing through PISA data to make it):

121910_ss001cCounting only countries that are actually countries (ie not Shanghai,) the US comes in #14. We scored better than 24 European countries, and significantly better than all of the Muslim, Latin American, and “other” countries in the data set.

“Above average among first world countries,” is a perfectly respectable place for a first world school system.

But you may have noticed the red bars in our graph. Yes, the US data is broken down by race, because the US is a significantly more diverse country than, say, Finland. Or Japan.

Asian Americans outscore Asians in Korea, Japan, Singapore, and Hong Kong. (and Taipei and Macao.) The only people on earth who are scoring better than our Asians are Shanghai’s Asians.

European Americans outscore Japan and every European country but Finland.

Latino Americans outscore every single Latino country in the dataset.

No African countries are represented in the dataset (though I hear Trinidad is half black,) probably due to the severe poverty of African countries. Nevertheless, just as African Americans outscore Trinidadians, I am confident that they would also outscore continental Africans were they concluded–there’s a pretty clear correlation here between development level and PISA scores.

121910_ss002In other words, whenever someone says, “American schools are failing,” what they really mean is “American blacks and Hispanics score worse than Europeans.”

Can we do better for our blacks and Hispanics? Perhaps, but any set of reforms that start out based on the notion that “the schools are failing” is highly unlikely to solve the problem of “blacks score worse than whites.”

2. We don’t spend enough on education.

3. But we’d do even better if we spent more.

4. Inner-city schools are underfunded.
Picture 13

From the National Center for Education Statistics report, Disparities in Public School District Spending, way back in the dark days of 1995.

“Actual” in this graph means what it sounds like: the actual amount of money districts spent per student.

“Multivariate Cost- and Need-Adjusted” controls for factors like the number of ESL and special ed. students in a district, (who are counted as multiple students because they cost more to educate;) local cost-of-educating differences, (eg, land for building a school on is more expensive in urban districts than rural ones;) and SES, (so that poor blacks are compared to equally poor whites.)

The authors summarize their findings:

More money is spent in districts with the highest percentages of minority students compared to districts with the lowest percentages of minority students ($4,514 versus $3,920). Although minority students in poverty are often viewed as those least served by current systems of public education funding, these findings suggest that while inequalities may remain for students in poverty, they do not appear to be driven by minority status. …

The distribution of public education resources is substantially more nearly equal than wealth measured by housing values, and somewhat less varied than wealth measured by household income.

State public education allocation systems are the primary equalizing factors of education resources, with some additional equalization resulting from the various federal funding programs. …

When socioeconomic status is measured by cost-adjusted median household income, however, and all other factors are held constant, the expenditures per student between the highest and lowest income groups differ by only $186 ($4,382 versus $4,196). …

Controlling for other school district characteristics, only school districts in the category with the fewest children in poverty spend substantially more per student.

But this is all very abstract. Let’s get a little more specific, with the Kansas City, Missouri (yes there is a “Kansas City” in Missouri,) inner-city school district:

To improve the education of black students and encourage desegregation, a federal judge invited the Kansas City, Missouri, School District to come up with a cost-is-no-object educational plan and ordered local and state taxpayers to find the money to pay for it.

Kansas City spent as much as $11,700 per pupil–more money per pupil, on a cost of living adjusted basis, than any other of the 280 largest districts in the country. The money bought higher teachers’ salaries, 15 new schools, and such amenities as an Olympic-sized swimming pool with an underwater viewing room, television and animation studios, a robotics lab, a 25-acre wildlife sanctuary, a zoo, a model United Nations with simultaneous translation capability, and field trips to Mexico and Senegal. The student-teacher ratio was 12 or 13 to 1, the lowest of any major school district in the country.

The results were dismal. Test scores did not rise; the black-white gap did not diminish; and there was less, not greater, integration.

The project ran from roughly 1985 through 1997. The article gives more details on everything they tried:

Once Clark decided for the plaintiffs, he didn’t ask them to do things on the cheap. When it came time to fill in the plan’s specifics, he invited them to “dream”(15)–to use their imaginations, push the envelope, try anything that would both achieve integration and raise student scores. The idea was that Kansas City would be a demonstration project in which the best and most modern educational thinking would for once be combined with the judicial will and the financial resources to do the job right. No longer would children go to schools with broken toilets, leaky roofs, tattered books, and inadequate curricula. The schools would use the most modern teaching techniques; have the best facilities and the most motivated teachers; and, on top of everything else, be thoroughly integrated, too. Kansas City would show what could be done if a school district had both the money and the will. …

By the time he recused himself from the case in March 1997, Clark had approved dozens of increases, bringing the total cost of the plan to over $2 billion–$1.5 billion from the state and $600 million from the school district (largely from increased property taxes).

With that money, the district built 15 new schools and renovated 54 others. Included were nearly five dozen magnet schools, which concentrated on such things as computer science, foreign languages, environmental science, and classical Greek athletics. Those schools featured such amenities as an Olympic-sized swimming pool with an underwater viewing room; a robotics lab; professional quality recording, television, and animation studios; theaters; a planetarium; an arboretum, a zoo, and a 25-acre wildlife sanctuary; a two-floor library, art gallery, and film studio; a mock court with a judge’s chamber and jury deliberation room; and a model United Nations with simultaneous translation capability.

To entice white students to come to Kansas City, the district had set aside $900,000 for advertising, including TV ads, brochures, and videocassettes. If a suburban student needed a ride, Kansas City had a special $6.4 million transportation budget for busing. If the student didn’t live on a bus route, the district would send a taxi. Once the students got to Kansas City, they could take courses in garment design, ceramics, and Suzuki violin. The computer magnet at Central High had 900 interconnected computers, one for every student in the school. In the performing arts school, students studied ballet, drama, and theater production. …

For students in the classical Greek athletic program, there were weight rooms, racquetball courts, and a six-lane indoor running track better than those found in many colleges. The high school fencing team, coached by the former Soviet Olympic fencing coach, took field trips to Senegal and Mexico.(18)

The ratio of students to instructional staff was 12 or 13 to 1, the lowest of any major school district in the country.(19) There was $25,000 worth of beads, blocks, cubes, weights, balls, flags, and other manipulatives in every Montessori-style elementary school classroom. Younger children took midday naps listening to everything from chamber music to “Songs of the Humpback Whale.” For working parents the district provided all-day kindergarten for youngsters and before- and after-school programs for older students.

Now you know why my parents thought it was a great idea to send me to a ghetto school. One year was more than enough.

It was more than the district could handle. District expenditures took quantum leaps from $125 million in fiscal year 1985 to $233 million in FY88 to $432 million in FY92.(21) There were too much largesse, too many resources, and too little security. A woman in the Finance Department went to jail for writing checks to her own account. Hundreds of thousands of dollars worth of equipment and supplies were lost to “rampant theft” every year.(22)

Perhaps the worst problem for what one school board president called the district’s “modestly qualified” administrators was the sheer volume of paperwork.(24) When the judge started building schools and inviting school principals to order whatever they wanted, purchase orders flooded into the central administrative office at the rate of 12,000 a month. Clerks were overwhelmed, devastated, and too ashamed to admit they couldn’t handle the crush. The system just collapsed.(25)

In other words, ghetto districts with falling-apart schools get that way because they have incompetent ghetto administrators who take the money for themselves instead of investing it in school maintenance. Giving them more money does not suddenly make them realize that stealing from little kids is immoral; it just means they steal more money.

And the honest ones among them were too dumb to run a school district to start with.

To outsiders, it appeared that the KCMSD had gone on a spending binge. At $400 million, Kansas City’s school budget was two to three times the size of those of similar districts elsewhere in the country. The Springfield, Missouri, school district, for instance, had 25,000 students, making it two-thirds as big as the KCMSD. Yet Springfield’s budget ($101 million) was only one-quarter to one-third the size of Kansas City’s ($432 million at its peak).(27)

Everything cost more in Kansas City.(28) Whereas nearby districts were routinely building 500-student elementary schools for around $3 million, in Kansas City comparably sized schools cost $5 million to $6 million. Whereas the nearby Blue Valley district built a 1,600-student high school at a cost of $20.5 million, including furniture and equipment, in Kansas City the 1,200-student Central High cost $33 million (it came with a field house larger than those of many colleges, ubiquitous computers, and an Olympic-sized swimming pool).(29) …

With some 600 employees for a district of 36,000 students, the KCMSD had a central administration that was three to five times larger than the administrations of other comparably sized public school districts. It was also 150 times larger than the administration of the city’s Catholic school system, in which four people–one superintendent, two assistant superintendents, and a part-time marketing manager–ran a school district of 14,000 students.(32) The KCMSD was so top-heavy that a 1991 audit discovered that 54 percent of the district’s budget never made it to the classroom; rather, it was used for food service, transportation, and, most of all, central administration.(33)

…44 percent of the entire state budget for elementary and secondary education was going to just the 9 percent of the state’s students who lived in Kansas City and St. Louis.(34)

So how did the schools do? Did test scores go up?

But despite a $900,000 television advertising budget and a $6.4 million special budget for door-to-door transportation of suburban students, the district did not attract the 5,000 to 10,000 white suburban students the designers of the desegregation plan had envisioned. The largest number it ever enrolled was 1,500, and most white students returned to their old suburban schools or to local private schools after one year … By the 1996-97 school year, only 387 suburban students were still attending school in the KCMSD.(71) … the cost of attracting those suburban students was half a million dollars per year per child.

Genuine question: Why even bother trying to attract white students? Why not just focus on making a great, outstanding school for the black kids? There is nothing special about sitting next to a white kid in class that makes black kids suddenly get better test scores. We don’t exude magic education rays. The best you can hope for is either 1. The districts’ test scores go up because they now have more high-scoring white students, which seems rather beside the point if your goal is to help black kids get better test scores, or 2. The white students help the black kids with their schoolwork, in which case the district is exploiting children as unpaid teachers.

And having been one of those kids exploited as unpaid teachers, my opinion of that is best expressed in all caps cursing. Children are not teachers; making one kid teach their peers results in their peers hating them and increased bullying and violence toward the kid.

Don’t make little kids do your job for you just because you can’t.

Continuing on:

Year after year the test scores would come out, the achievement levels would be no higher than before, and the black-white gap (one-half a standard deviation on a standard bell curve) would be no smaller.(81) Although the initial gap was small, by the 12th grade, blacks’ scores on standardized tests were about three years behind those of whites (10.1 vs. 13.1).(82) At Central High School, which tended to attract suburban white computer hackers, white males were five years ahead of black males on standardized tests.(83) … 

The average black student’s reading skills increased by only 1.1 grade equivalents in four years of high school.(89) At Central High, complained Clark, black males were actually scoring no higher on standardized tests when they graduated as seniors than they had when they enrolled as freshmen four years before.(90)

In perhaps the biggest surprise, Armor’s studies found that black elementary students who go to magnet schools (which have the highest percentages of whites) score no better on standardized tests than do blacks who go to all-black nonmagnet schools.(97) In short, Armor found that, contrary to the notion on which the whole desegregation plan was founded–that going to school with middle-class whites would increase blacks’ achievement–the Kansas City experiment showed that “integration has no effect.”(98) …

Finally, the district had discovered that it was easier to meet the court’s 60/40 integration ratio by letting black students drop out than by convincing white students to move in. As a result, nothing was done in the early days of the desegregation plan about the district’s appalling high school dropout rate, which averaged about 56 percent in the early 1990s (when desegregation pressures were most intense) and went as high as 71 percent at some schools (for black males it was higher still).(109)…

Although Kansas City did increase teacher pay a total of 40 percent to an average of about $37,000 (maximum was $49,008 per year for Ph.D.s with 20 years experience), test scores for the district were consistently below state and national averages.(121) Parochial school teachers, in contrast, earned an average of $24,423, but their students’ test scores were consistently above state and national averages.(122)

In fact, the supposedly straightforward correspondence between student achievement and money spent, which educators had been insisting on for decades, didn’t seem to exist in the KCMSD. At the peak of spending in 1991-92, Kansas City was shelling out over $11,700 per student per year.(123) For the 1996-97 school year, the district’s cost per student was $9,407, an amount larger, on a cost-of-living-adjusted basis, than any of the country’s 280 largest school districts spent.(124) Missouri’s average cost per pupil, in contrast, was about $5,132 (excluding transportation and construction), and the per pupil cost in the Kansas City parochial system was a mere $2,884.(125)

Oh, does anyone remember that time Zuckerberg gave the Newark School District 100 million dollars in 2010, and it completely disappeared and did absolutely nothing?

As for the district schools forced — or incentivized — to compete with charters, those involved with the Newark effort point to green shoots of change. Graduation rates are up. More higher- rated teachers are staying than lower- performing ones. Still, on state tests of third- to eighth-graders, math and reading proficiency went down in all six grades between 2011 and 2014.

5. The teachers are incompetent.

This seems to be the conservatives’ favorite response to cases like Newark and Kansas City. Oh, if only we could just fire all of the teachers and replace them with different teachers, then test scores would go up! And we need some kind of standardized, “Common Core” taught in all of the schools so that incompetent teachers can’t get away with not teaching their students!

I find this attitude really hostile to teachers, the vast majority of whom are genuinely hard working and dedicated folks. I’ve attended plenty of schools, had a wide variety of teachers, and all of them did a perfectly good job of teaching. (I did have a couple I didn’t like personally, but I still learned from them.) Student performance has a lot more to do with the students than with the teachers:

In summary: teacher quality probably explains 10% of the variation in same-year test scores. A +1 SD better teacher might cause a +0.1 SD year-on-year improvement in test scores. This decays quickly with time and is probably disappears entirely after four or five years, though there may also be small lingering effects.

If teacher quality explains 10% of the variation, then student quality (and random chance) explain 90% of the variation.

Some kids, when you hand them a standardized test, take one look at it and say, “NOPE.” Young boys, in particular, do not seem well suited to sitting still for long hours every day doing worksheets, reading books, or taking tests. Young girls, by contrast, are much better at simply being still and concentrating.

This is not the teachers’ fault.

Some kids get substantially more help at home than other kids. Homework help, tutoring help, breakfast, lead levels in their environment, etc. Regardless of what these things do to long-term outcomes, they certainly make a short-term difference on standardized tests in fourth grade.

This is not the teachers’ fault.

And some kids are just plain smarter or harder working than other kids.

This is also not the teachers’ fault.

I’m sure there are bad teachers; there may be significant impediments to firing them. But they are not some sort of massive, nation-wide problem that requires us to pour millions of dollars into dictating the curriculum, (which, ironically, prevents them from teaching “above grade level” material to students who would benefit from it,) and scrutinizing their every move like some sort of educational panopticon.

Remember, teachers back in 1910-1930 managed to educate their students well enough that they sent a man to the moon.

What about these findings of long-term financial gains from having a superior kindergarten teacher, or having three great teachers in a row vs. having three terrible teachers in a row?

I’m going with data is confounded all to hell.

Well-off parents buy outrageously expensive houses in all-white districts in order to send their kids to schools with other whites (and Asians.) “For the test scores,” of course. Since teacher quality is determined by test scores, which is in turn determined by the intelligence of the other kids in the class (or at least how much they’ve crammed for the test,) all this is telling us is that slightly dumb rich kids do well financially later in life because they come from well-off families.

The only kids who are enduring three of the worst teachers in a row are the absolute poorest kid whose parents either don’t give a shit about their educations or have zero ability to get them transferred to a different school or classroom. And after three years of bad teachers, I bet I’d stop bothering to fill out the standardized tests, either, and would just spend the time doodling dragons all over the paper. That kids with zero educational support and extremely impoverished backgrounds end up doing badly in life really shouldn’t surprise us.

But because we are talking about having three particularly good or bad teachers in a row, only 1/125 students fall into either category. The vast majority of students–over 99%–get a variety of different teachers, and most teachers are decent.

Could bad teachers be concentrated in ghetto school districts? Perhaps they are–though remember, these districts are still paying their teachers more than the average Catholic school, so I doubt teacher pay is really the problem. And I’ve yet to hear anyone espouse an explanation for why ghetto schools supposedly attract bad teachers besides “bad pay.”

To be clear: we’ve denigrated and cast all teachers under suspicion and greatly interfered with their ability to run their classrooms all because teachers in the ghettos can’t raise their students’ test scores.

If a particular teacher is a real problem, let the parents of the students in that teacher’s class present their troubles to the school board and let the board make a determination.

6. SAT scores are just a product of your parents’ income.

SAT scores by race and parental income
SAT scores by race and parental income

Sorry the graph is small. The Y axis is SAT scores and the X axis is parental income.

The top line, dark orange, is Asian math scores. Dark blue = white math. Light blue = white verbal. Dark red = Mexican math. Black = black math. Light orange = Asian verbal. Pink = Mexican verbal. Grey = black verbal.

The richest black kids in the country have worse math scores than the poorest whites and Asians. The richest Mexicans have math scores on par with the poorest Asians and only slightly above working class whites. On verbal scores, blacks at all income levels score worse than their similarly-monied peers for whom English is most likely a second language.

And as we’ve already seen district funding doesn’t actually vary that much with parental income. Rich people do indeed pay for more tutoring and better teachers for their kids, but this is heavily confounded by the fact that smart people tend to go to college, get degrees, go into high-paying professions, and then have kids who are also pretty smart, while dumb people drop out of highschool, get shitty jobs, make very little money, and end up with kids who are similarly dumb.

7. More education will jump-start the economy and solve all woes.

Why are Asians harder hit by Recessions?

US_real_median_household_income_1967_-_2011

So I was just looking up some demographic data on Wikipedia and ran across this graph. Two interesting things:

  1. During the recessions, all of the groups suffer in roughly similar amounts, except Asians, who tend to get really hammered. I don’t think it’s a side-effect of just having the biggest quantity of money, as whites and blacks, who make very different amounts of money, still tend to fall by the same amount. I would assume this is a result of Asians being more heavily leveraged, with risky investments, except that this is a graph of income rather than net worth. Maybe they are disproportionately employed in highly leveraged professions?
  2. The 1990 recession looks like it went on particularly long for Hispanics, whose net worth kept hurting after everyone else’s had started recovering–around 1995, the Hispanic nadir, their net worth was nearly as low as African Americans’. What was up? Economic problems related to the Mexican Peso? Refugees from the Guatemalan Civil War? NAFTA?

Thoughts?

Cathedral Round-Up #13: Do Universities do Anything Good?

A commentator last month asked if universities do anything good, so I though I would begin this month’s Cathedral Round-Up by searching for some good news.

Caltech seems to be still doing real research:

And some researchers at MIT are collaborating with folks at Mass General Hospital to improve methods for placing epidurals:

More than 13 million pain-blocking epidural procedures are performed every year in the United States. Although epidurals are generally regarded as safe, there are complications in up to 10 percent of cases, in which the needles are inserted too far or placed in the wrong tissue.

A team of researchers from MIT and Massachusetts General Hospital hopes to improve those numbers with a new sensor that can be embedded into an epidural needle, helping anesthesia doctors guide the needle to the correct location.

Since inserting a giant needle into your spine is really freaky, but going through natural childbirth is hideously painful, I strongly support this kind of research.

Meanwhile, of course:

Forbes notes:

More than half of Americans under the age of 25 who have a bachelor’s degree are either unemployed or underemployed. According to The Christian Science Monitor, nearly 1 percent of bartenders and 14 percent of parking lot attendants have a bachelor’s degree.

Adding additional degrees is no guarantee of employment either. According to a recent Urban Institute report, nearly 300,000 Americans with master’s degrees and over 30,000 with doctorates are on public relief. …

Unless you have a “hard” skill, such as a mastery of accounting, or a vocational certificates (e.g., in teaching) your liberal arts education generally will not equip you with the skill set that an employer will need.

Obviously colleges still do some good things. Much of the research I cite here in this blog originated at a college of some sort. And of course, if you are careful and forward thinking, you can use college to obtain useful skills/information.

But between the years, money, and effort students spend, not to mention the absurd political indoctrination, college is probably a net negative for most students.

A few doctors in the 1400s probably saved the lives of their patients, but far more killed them.

Caveat emptor.

Anthropology Friday: In the Shadow of Man (3/5)

Chimpanzee family from the Gombe
Chimpanzee family from the Gombe

(Do you know what’s frustrating? When you discover that you can type about three times faster than the words actually show up on your computer screen.)

Anyway, today we are continuing with our discussion of Jane Goodall’s In the Shadow of Man, featuring the adventures of chimpanzees from The Gombe Stream National Park, Tanzania. The book contains many interesting vignettes of chimpanzee life and descriptions of their social order. I wish I could share more of them, but my fingers are tired of typing, so here we go. (As usual, for readability I’m just using “” for the quotes instead of block quotes, and they’re organized around several themes.) I’ve tried to bold the names of the chimps the first time they appear.

Hunting and the sharing of meat:

“One day I arrived on the Peak and found a small group of chimps just below me in the upper branches of a thick tree. As I watched I saw that one of them was holding a pink-looking object from which he was from time to time pulling pieces with his teeth. There was a female and a youngster and they were both reaching out toward the male, their hands actually touching his mouth. Presently the female picked up a piece of the pink thing and put it to her mouth: it was at this moment that I realized the chimps were eating meat.

“After each bite of meat the male picked off some leaves with his lips and chewed them with the flesh. Often, when he had chewed for several minutes on this leafy wad, eh spat out the remains into the waiting hands of the female. Suddenly he dropped a small piece of meat, and like a flash the youngster sung after it to the ground. Even as he reached dot pick it up the undergrowth exploded and an adult bushpig charged toward him. … Soon I made out the shapes of three small striped piglets. Obviously the chimps were eating a baby pig. The size was right and later, when I realized that the male was David Graybeard, I moved closer and saw that he was indeed eating piglet.

“For three hours I watched the chimps feeding. David occasionally let the female bite pieces from the carcass and once he actually detached a small piece of flesh and placed it in her outstretched hand. When he finally climbed down there was still meat on the carcass; he carried it away in one hand, followed by the others.”

EvX: it is much easier to dismember carcases when you have tools at your disposal, like stone knives.

“I had taken Hugo [animal photographer and Jane’s future husband] up to show him the peak and we were watching four red colobus monkeys that were evidently separated from their troop. Suddenly an adolescent male chimpanzee climbed cautiously up the tree next to the monkeys and slowly along a branch. Then he sat down. After a moment, three of the monkeys jumped away–quite calmly, it appeared. The fourth remained, his head turned toward the chimp. A second later another adolescent male chimp climbed out of the thick vegetation surrounding the tree, rushed along the branch along which the last monkey was sitting, and grabbed it. Instantly several other chimps climbed up into the tree, and, screaming and barking in excitement, tore their victim into several pieces. It was all over within a minute from the time of capture. …

“During the ten years that have passed since I began work at the Gombe Stream we have recorded chimpanzees feeding on the young of bushbucks, bushpigs, and baboons, as well as both young and small adult colobus monkeys, redtail monkeys, and blue monkeys. And there are two cases on record of chimpanzees in the area actually taking off African babies–presumably as prey, since when recovered from an adult male chimpanzee one infant had had its limbs partially eaten. …

“On other occasions, the hunting seems to be a much more deliberate, purposeful activity, and often at such times the different individuals of a chimpanzee group show quite remarkable cooperation–as when different chimpanzees station themselves at the bases of trees offering escape routes to a cornered victim.

After Rodolf kills a baboon:
“Presently the four chimpanzees emerged from the undergrowth and climbed into the higher branches of a tall tree, whee Rodolf settled down and began to feed…

“Other chimpanzees in the valley, attracted by the loud screaming and calling that typifies a hunt and kill, soon appeared in the tree, and a group of high-ranking males clustered around Rodolf, begging for a share of his kill. Often I have watched chimpanzees begging for meat, and usually a male who has a reasonably large portion permits at least some of the group to share with him. Rodolf, on the contrary, protected his kill jealously that day. …

“Rodolf kept almost the entire carcass to himself for nine hours that day, although from time to time he spat a wad of meat and leaves into a into a begging hand, or one of the other males managed to grab a piece from the carcass and make off with it. …

“At this time, the third year of Mike‘s supremacy, Rodolf was no longer the high-ranking male he had once been. How was it, then, that he dared push away Mike’s hand, he who normally went into a frenzy of submission when Mike approached him? … I had seen this sort of apparent inconsistency before during meat-eating episodes and I often wondered whether the chimps were showing the crude beginnings of a sot of moral values. Rodolf killed the baboon, therefore, the meat was Rodolf’s. More serious consideration of the behavior has led me to that something rather different maybe involved.

“Mike would have attacked Rodolf without hesitation had the prize been a pile of Bananas, yet if Rodolf had gathered the fruits from a box for himself they would have been his property quite as legitimately as as was the meat. I wonder, then, if the principle involved may be similar to the one governing a territorial animal within his own territory, when he is more aggressive, more likely to fight off an intruder, than if he met the same animal outside his territorial boundary. Meat is much liked, much prized food item. An adult male in possession of such a prize may become more willing to fight for it, and therefore, be less apprehensive of his superiors than if he has a pile of everyday fruits like bananas. In support of this theory, I should mention that in the early days, when bananas were something of a novelty, the chimps very seldom did fight over the fruits.”

EvX: The lack of sharing makes the normally dominant males very frustrated and aggressive toward everyone else in the vicinity during these meat-eating episodes. Often, though, quite a bit of sharing of meat occurs.]

On baboons:

“The baboons very soon made themselves at home around our camp, too, and Vanne [Jane’s mother] quickly learned never to leave the tents unguarded. About two weeks after our arrival she went for a short walk; when she returned it was to find our belongings strewn in all directions, and one blase male baboon sitting by the overturned table polishing off the loaf that Dominic had baked that morning. …

“It was far worse when one morning Vanne, who had been dozing after my early departure, suddenly heard a small sound in the tent. She opened her eyes and there, silhouetted in the entrance, she saw a huge male baboon. He and she remained motionless fr a few moments and then he opened his mouth in a tremendous yawn of threat. In the gray light Vanne could just see the gleam of his teeth and she thought her last hour had come. With a sudden yell she sat bolt upright in bed, waving her arms, and her unwelcome visitor fled. He was a horrible baboon, that one, an old male who took to hanging around our camp at all hours of the day, lurking in the undergrowth and dashing out whenever opportunity presented to steal a loaf of bread.”

The Rain Dance:

“At about noon the first heavy drops of rain began to fall. … At that moment the storm broke. The rain was torrential, and the sudden clap of thunder, right overhead, made me jump. As if this were a signal, one of the big males stood upright and as he swayed and swaggered rhythmically from foot to foot I could hear the rising crescendo of his pant-hoots above the beating of the rain. Then he charged, flat-out down the slope toward the trees he had just left. He ran some thirty yards, and then, swinging round the trunk of a small tree to break his headlong rush, leaped into the low branches and sat motionless.

“Almost at once two other males charged after him. One broke off a low branch from a tree as he ran and brandished it in the air before hurling it ahead of him. The other, as he reached the end of his run, stood upright and rhythmically swayed the branches of a tree back and forth before seizing a huge branch and dragging it farther down the slope. A fourth male, as he too charged, leaped into a tree and, almost without breaking speed, tore off a large branch, leaped with it to the ground, and continued down the slope. As the last two males called and charged down, so the one who had started the whole performance climbed from his tree and began plodding up the slope again. The others, who had also climbed into trees near the bottom of the slope, followed suit. When they reached the ridge, they began charging down all over again, one after the other, with equal vigor. …

“As the males charged down and plodded back up, so the rain fell harder, jagged forks or brilliant flares of lightning lit up the leaden sky, and the crashing of thunder seemed to shake the very mountains. …

“I would only see such a display twice more in the next ten years.”

EvX: the chimps do not build nor take any kind of shelter from the rain, but just sit hunched up in it, looking pretty miserable for much of the rainy season.

Getting to know the chimps:

[Jane, upon hearing some chimps nearby, lies down flat on the ground to avoid disturbing them/being seen]

“Suddenly I saw a large male chimpanzee climbing a tree only a couple of yards away. He moved over into the branches over my head and began screaming at me, short, loud, high-pitched sounds, with his mouth open. … He began climbing down toward me until he was no more than ten feet above me and I could see his yellow teeth… He shook a branch, showering me with twigs. Then he hit the trunk and shook more branches, and continued to scream and scream and work himself into a frenzy of rage. All at once he climbed down and went out of sight behind me.

“It was then that I saw a female with a tiny baby and an older child sitting in another tree and staring at me with wide eyes. They were quite silent and quite still. I could hear the old male moving about behind me and then his footsteps stopped. He was so close by that I could hear his breathing.

“Without warning there was a loud bark, a stamping in the leaves, and my head was hit, hard. At this I had to move, had to sit up. The male was standing looking at me, and for a moment I believed he would charge; but he turned and moved off, stopping often to turn and stare at me. The female with her baby and the youngster climbed down silently and moved after him. There was a sense of triumph: I had made contact with a wild chimpanzee–or perhaps it should be the other way around.

“When I looked back some years later at my description of that male, I was certain it was the bad-tempered, irascible, paunchy J.B. … I suppose he was puzzled by my immobility and the plastic sheet that was protecting me from the light rain. He simply had to find out exactly what I was and make me move–he must have known, from my eyes, that I was alive. …

“One evening I returned to camp and found Dominic and Hassan very excited. A large male chimpanzee, they told me, had walked right into camp and spent an hour feeding in the palm tree that shaded my tent. …

David Greybeard and Jane Goodall hold hands, from Jane's blog
David Greybeard and Jane Goodall hold hands, from Jane’s blog

“One day as I sat on the veranda of the tent, David climbed down from his tree and then, in his deliberate way, walked straight toward me. When he was about five feet from me he stopped, and slowly his hair began to stand on end, until he looked enormous and very fierce. A chimpanzee may erect his hair when he is angry, frustrated, or nervous. Why had David now put his hair out? All at once he ran straight at me, snatched up a banana from my table, and hurried off to eat it farther away. Gradually his hair returned to its normal sleeked position.

“After that incident I asked Dominic to leave bananas out whenever he saw David, and so, even when there were no ripe palm nuts, the chimp still wandered into camp sometimes, looking for bananas. …”

EvX: This marks the beginning of the feeding stations, which took several years to perfect (you can’t just hand out bananas all day; eventually the chimps stop doing normal chimp things and just sit there all day waiting for more bananas,) but were critical in getting the chimps to regularly appear in the same places so that Jane and other researchers could actually gather data on them. So the researchers have had to balance between “ability to gather data” and “behavior changes due to free bananas.”

To be continued.

The big 6 part 6: The Vigesimal Olmecs

Olmec civilization heartland
Olmec civilization heartland

It appears that the Olmecs–our final civilization in this series (1500-400 BC)–had a vigesimal, or base 20, counting system.

Counting is one of those things that you learn to do so young and so thoroughly that you hardly give it a second thought; after a few hiccups around the age of five, when it seems logical that 11=2, the place value system also becomes second nature. So it is a bit disconcerting to realize that numbers do not actually divide naturally into groups of ten, that’s just a random culturally determined thing that we happen to do. (Well, it isn’t totally random–ten was probably chosen because our ancestors were counting on their fingers.)

Stela C, from Tres Zapotes, showing the date September 1, 32 BCE
Stela C, from Tres Zapotes, showing the date September 1, 32 BCE

But plenty of societies throughout history have used other bases. The Yuki of California used base 8 (they counted the spaces between fingers;) the Chumash use(d) base 4; Gumatj uses base 5. There are also reports of bases 12, 15, 25, 32, and 6. (And many hunter-gatherer societies never really developed words for numbers over three or so, though they easily employed phrases like “three threes” to mean “nine.”)

The Yoruba, Olmec, Maya, Aztec, Tlingit, Inuit, Bhutanese, Atong, Santali, Didei, Ainu all use (or used) base 20. Wikipedia suggests that the Mayans may have used their fingers and toes to count; I suggest they used the knuckles+fingertips on one hand, or in a sort of impromptu place-value system, used the fingers of one hand to represent 1-5, and the fingers of the other hand to represent completed groups of five. (eg, 3 fingers on your left hand = 3; 3 fingers on your right hand = 15.)

Mayan Numerals
Mayan Numerals

Everything I have seen of reliable genetics and anthropology suggests that the Olmecs and Mayans were related–for example, one of the first known Mayan calendars/Mayan dates was carved into the Mojarra Stela by the “Epi-Olmec” people who succeeded the Olmecs and lived in the Olmec city of Tres Zapotes. Of course this does not mean that the Olmecs themselves developed the calendar or written numbers, (though they could have,) but it strongly implies that they had the same base-20 counting system.

You can compare for yourself the numbers found on the Tres Zapotes stela (above) and the Mayan numerals (left.)

In base-10, we have special words for multiples of 10, like ten, twenty, ninety, hundred, thousand, etc. In a base-20 system, you have special words for multiples of 20, like twenty, (k‘áal, in Mayan;) forty, (ka’ k’áal, or “two twenties;”) four hundred, (bak😉 8,000, (pic😉 160,000 (calab;) etc.  Picture 13

Wikipedia helpfully provides a base-20 multiplication table, just in case you ever need to multiply in base-20.

The Olmecs, like the Egyptians and Sumerians, produced art (particularly sculptures,) monumental architecture, (pyramids,) and probably had writing and math. They raised corn, chocolate, (unsweetened,) squash, beans, avocados, sweet potatoes, cotton, turkeys, and dogs. (It appears the dogs were also eaten, “Despite the wide range of hunting and fishing available, midden surveys in San Lorenzo have found that the domesticated dog was the single most plentiful source of animal protein,[93]” possibly due to the relative lack of other domesticated animals, like cows.)

Cocoa pods
Cocoa pods

They also appear to have practiced ritual bloodletting (a kind of self-sacrifice in which the individual makes themselves bleed, in this case often by drawing sharp objects through their tongues, ears, or foreskins, or otherwise cutting or piercing these,) and played the Mesoamerican ballgame popular later with the Mayans and Aztecs. Whether these practices spread via cultural diffusion to other Meoamerican cultures or simply indicate some shared cultural ancestry, I don’t know.

Their sculptures are particularly interesting and display a sophisticated level of artistic skill, especially compared to, say, Norte Chico (though in its defense, Norte Chico did come earlier):

A lot of people think the Olmec stone heads look a lot like Africans (and I can see why,) but–as lots of people have pointed out–they also look a lot like the local Indians who live in the area today, and so far I haven’t run across any genetic studies that indicate African DNA (which is quite distinctive) in any Native American population (aside from the DNA we all share from our common, pre-out-of-Africa ancestors, 70,000-100,000 years ago.) (There is one tiny isolated tribe over in Baja CA, [Mexico,] quite far from where the Olmecs lived, who do have some interesting DNA stuff going on that could indicate contact with Africa or somewhere else, but it could also just indicate random genetic mutation in an extremely isolated, small population. At any rate, they are irrelevant to the Olmecs.)

Frank Johnson, in his post Mystery Solved: Olmecs and Transoceanic Contact, goes through the laundry list of questionable claims about the Olmecs and does a great job of laying out various proofs against them. While I would not totally rule out the possibility of trans-Atlantic (or trans-Pacific) contact between various groups, just because human history is long and full of mysteries, the most sensible explanation of the origins and cultural development of Olmec society is the simplest: the Olmecs were a local indigenous people, probably closely related to most if not all of their neighbors, who happened to start building cities and pyramids.

 

Anthropology Friday: In the Shadow of Man (pt. 2/5): War

Location of the Gombe Stream National Park, Tanzania
Location of the Gombe Stream National Park, Tanzania

Welcome back to our discussion of Jane Goodall’s In the Shadow of Man, an account of chimpanzee life in the Gombe National Park, Tanzania. I enjoyed this book quite a bit; my chief difficulty has been deciding which parts to excerpt for you.

Tanzania borders the DRC ne Congo ne Belgian Congo, which was (coincidentally) the location of our previous Anthropology Friday selection, Isaac Bacirongo’s Still a Pygmy.

The book begins with the difficulties inherent in setting up the research–obtaining permits and funding, overcoming the locals’ distrust, (they of course did not believe that this white woman actually wanted to live in the forest and stare at monkeys all day,) and a massive influx of refugees:

Once we reached Nairobi, however, I could think of nothing save the excitement of the eight-hundred-mile journey to Kigoma–and the chimpanzees. … When we reached Kigoma, however, after a dusty three days on the road, we found the whole town in a state of chaos. Since we had left Nairobi violence and bloodshed had erupted in the Congo, which lay only some twenty-five miles to the west of Kigoma, on the other side of lake Tanganyika. Kigoma was overrun by boatloads of Belgian refugees. …

Eventually we ran the District Commissioner to earth, and he explained, regretfully but firmly, that there was no chance at all of my proceeding to the chimpanzee reserve. First it was necessary to wait and find out how the local Kigoma district Africans would react to the tales of rioting and disorder in the Congo. …

Bernard shared his room with two homeless Belgians, and we even got out our three camp beds and lent them to the harassed hotel owner. Every room was crammed, but these refugees were in paradise compared to those housed in the huge warehouse, normally used for storing cargo… There everyone slept in long rows on mattresses or merely blankets on the cement floor, and queued up in the hundreds for the scant meals that Kigoma was able to provide for them.

… On our second evening in Kigoma we three and a few others made two thousand SPAM sandwiches. …

Two evenings later most of the refugees had gone, carried off by a series of extra trains to Tanganyika’s capital, Dar es Salaam.

Belgian refugees fleeing violence in the Congo, 1960
Belgian refugees fleeing violence in the Congo, 1960

There follows a nice description of the town of Kigoma itself, and of course there is soon a great deal of material about chimpanzees and rather little about humans. Jane doesn’t mention the refugees again. (To be fair, isolation probably meant that she had rather little knowledge about most human affairs for most of the 60s and 70s.)

So who were these refugees? Where did they come from, and why?

Obviously they were Belgians, from the Congo. We briefly covered this conflict back in Anthropology Friday: War, Violence, and More War:

Patrice Lumumba was an anti-colonialist protestor who was jailed for opposing Belgian rule in the Congo and became the first democratically elected prime minister of the DRC.

He then gave raises to everyone in the government except the military, so of course the military revolted. He asked the UN for help putting down the rebellion, but the UN sucked so he went to the Soviets.

The Wikipedia page on the Congo Crisis gives far more detail on this conflict–notably, it blames the outbreak of the crisis not on Lumumba failing to give the army a raise, but on a Belgian military commander’s speech:

Lieutenant-General Émile Janssens, the Belgian commander of the Force Publique, refused to see Congolese independence as marking a change in the nature of command.[36] The day after the independence festivities, he gathered the black non-commissioned officers of his Léopoldville garrison and told them that things under his command would stay the same, summarising the point by writing “Before Independence = After Independence” on a blackboard.

Basically, the Belgians officially proclaimed that the Republic of the Congo was independent on June 30, 1960, thirty years earlier than they had intended to. They seemed to have thought they could get people to stop protesting against Belgian rule by “officially” handing over power, but would still run everything. After all, while the colony had been advancing rapidly in recent decades–

During the 1940s and 1950s, the Congo experienced an unprecedented level of urbanisation and the colonial administration began various development programmes aimed at making the territory into a “model colony”.[10] One of the results of the measures was the development of a new middle class of Europeanised African “évolués” in the cities.[10] By the 1950s the Congo had a wage labour force twice as large as that in any other African colony.[11]

–most native Congolese still weren’t well-educated in the fields thought necessary to run a country (or army.)

The idea that the Congolese were too dumb and inexperienced to run their own country and therefore needed the Belgians to do it for them went over great with the army:

This message was hugely unpopular among the rank and file—many of the men had expected rapid promotions and increases in pay to accompany independence.[36] On 5 July, several units mutinied against their white officers at Camp Hardy near Thysville. The insurrection spread to Léopoldville the next day and later to garrisons across the country.[37]

Rather than deploying Belgian troops against the mutineers as Janssens had wished, Lumumba dismissed him and renamed the Force Publique the Armée Nationale Congolaise (ANC). All black soldiers were promoted by at least one rank.[38]Victor Lundula was promoted directly from sergeant-major to major-general and head of the army, replacing Janssens.[37]

Of course, the Congolese proved the Belgians wrong by transforming their country into one of the world’s best-run economic powerhouses with an astonishing per capita GDP of $499 and reports of cannibalism. (By contrast, the nearby country of Botswana has a per cap GDP of over $6,000.)

But back to the post-independence anti-Belgian violence:

The government attempted to stop the revolt… but in most of the country the mutiny intensified. White officers and civilians were attacked, white-owned properties were looted and white women were raped.[37] The Belgian government became deeply concerned by the situation, particularly when white civilians began entering neighbouring countries as refugees.[40]

A 1960s newsreel reports:

Violence and chaos in the Congo. Barely 11 days after official independence from Belgium, Congolese troops begin a wave of attacks and looting throughout the fare flung sectors of the former colony. Meanwhile in Belgium and African countries bordering on the Congo, refugees are pouring in with harrowing tales of violence and of hasty flight. …

The mutiny first started only four days after independence, on July 4, 1960, in the camp outside Leopoldville. The rebels used machetes on their white officers and broke into the armory. On day eight, all 1000+ Belgian officers were removed from their positions, and replaced with Congolese. With or without an Africanized officer corps, the soldiers are running amok throughout the Congo, and panic-stricken whites are fleeing in all directions. Numerous European targets have been attacked.

The flight of officers has left the army totally uncontrolled, and the new country has no effective instrument to control the territory.

Back to Wikipedia:

… On 9 July, Belgium deployed paratroopers, without the Congolese state’s permission, in Kabalo and elsewhere to protect fleeing white civilians.[41] …At Lumumba’s request, white civilians from the port city of Matadi were evacuated by the Belgian Navy on 11 July. Belgian ships then bombarded the city; at least 19 civilians were killed. This action prompted renewed attacks on whites across the country, while Belgian forces entered other towns and cities, including Léopoldville, and clashed with Congolese troops.[40]

This one is captioned “Mike Hoare and Belgian Congo Armed Forces evacuating refugees 1969.” Let me know if that’s inaccurate.

Then parts of the Congo started secede. UN “Peace Keeping” troops tried to get people to stop fighting but without actually defeating once side or the other, so predictably people kept killing each other. The Prime Minister, Lumumba, went to the Soviets for help, which concerned everyone because the Congo made a lot of money selling uranium to the US, which used it in atomic bombs, so the Congolese President dismissed Lumumba and Lumumba dismissed the President, at which point Mobutu dismissed both of them (leading pro-Lumumba protesters in Yugoslavia to attack the local Belgian embassy,) and had Lumumba shot. Mobutu, while awful in many ways, did end the civil war and restore a modicum of order.

“Mad” Mike Hoare was a Irish mercenary active in the Congo and elsewhere in Africa:

In 1964, Congolese Prime Minister Moïse Tshombe, his employeer back in Katanga, hired “Major” Mike Hoare to lead a military unit called 5 Commando, Armée Nationale Congolaise (5 Commando ANC) (later led by John Peters) (not to be confused with No.5 Commando, the British Second World War commando force) made up of about 300 men most of whom were from South Africa. … The unit’s mission was to fight a revolt known as the Simba Rebellion.

Later Hoare and his mercenaries worked in concert with Belgian paratroopers, Cuban exile pilots, and CIA-hired mercenaries who attempted to save 1,600 civilians (mostly Europeans and missionaries) in Stanleyville from the Simba rebels in Operation Dragon Rouge. This operation saved many lives.[3] Hoare was later promoted to Lieutenant-Colonel in the Armée Nationale Congolaise and 5 Commando expanded into a two-battalion force. Hoare commanded 5 Commando from July 1964 to November 1965.[4]

Mad Mike once tried to conquer the Seychelles, but failed when customs officials noticed his groups’ weapons.

Many of the Belgian refugees, meanwhile, fled to the British colony of Southern Rhodesia, which became just “Rhodesia” after Northern Rhodesia changed its name to Zambia (one of the obscurer African countries, with a per cap GDP of $1,143) The white folks + refugees of Southern Rhodesia took one look at the chaos over in the Congo, said “Nope,” and declared themselves independent of Great Britain to avoid handing over power to the black majority (97% of the Rhodesian population.)

The rest of the world (Great Britain included) never officially recognized Rhodesia as a country and hit it with a bunch of sanctions. According to Wikipedia:

Although prepared to grant formal independence to Southern Rhodesia (now Rhodesia), the British government had adopted a policy of no independence before majority rule, dictating that colonies with a substantial population of European settlers would not receive independence except under conditions of majority rule.[20][21][22]

After the federal break-up in 1963, then-Prime Minister Alec Douglas-Home insisted that preconditions on independence talks hinge on what he termed the “five principles” – unimpeded progress to majority rule, assurance against any future legislation decidedly detrimental to black interests, “improvement in the political status” of local Africans, moves towards ending racial discrimination, and agreement on a settlement which could be “acceptable to the whole population”.[25][26][27][28]

Note that Douglas-Home here is the head of the British conservatives.

Harold Wilson and his incoming Labour government took an even harder line on demanding that these points be legitimately addressed before an independence agenda could be set.[24] …

However, few seemed to initially realise that Rhodesia was no longer within the Commonwealth’s direct sphere of influence and British rule was now a constitutional fiction; Salisbury remained virtually immune to credible metropolitan leverage.[15]

In October 1965, the United Nations Security Council had warned Whitehall about the possibility of UDI, urging Wilson to use all means at his disposal (including military pressure) to prevent the Rhodesian Front from asserting independence.[44] After UDI was proclaimed, UN officials branded Ian Smith’s government as an “illegal racist minority regime”[45] and called on member states to sever economic ties with Rhodesia, recommending sanctions on petroleum products and military hardware.[24] In December 1966, these measures became mandatory, extending to bar the purchase of Rhodesian tobacco, chrome, copper, asbestos, sugar, meat, and hides.[24]

Britain, having already adopted extensive sanctions of its own, dispatched a Royal Navy squadron to monitor oil deliveries in the port of Beira, from which a strategic pipeline ran to Umtali. The warships were to deter “by force, if necessary, vessels reasonably believed to be carrying oil destined for (Southern) Rhodesia”.[46][47]

Meanwhile, of course, no one is allowed to vote in Saudi Arabia, but no one seems to care about that.

You probably know the story by now: the USSR supported the black nationalists, pretty much no one supported the white Rhodesians, and eventually they got tired of civil war and gave up. According to Wikipedia:

In the ten years after independence, around 60% of the white population of Zimbabwe emigrated, most to South Africa and to other mainly white, English speaking countries where they formed expatriate communities. …

While as Rhodesia, the country was once considered the breadbasket of Africa. Today, Zimbabwe is a net importer of foodstuffs, with the European Union and United States providing emergency food relief as humanitarian aid on a regular basis.[151] The nation has suffered profound economic and social decline in the past twenty years. Recently the agriculture sector has started to do well since the availability of expertise and machines has improved supported mainly by China.[152][153]

Zimbabwe also suffered from a crippling inflation rate, as the Reserve Bank of Zimbabwe had a policy of printing money to satisfy government debts, which introduces excessive currency into the economic system which led to the demise of the local currency. This policy caused the inflation rate to soar from 32% in 1998 (considered extremely high by most economic standards) to an astonishing 11,200,000% by 2007. Monetary aid by the International Monetary Fund has been suspended due to the Zimbabwe government’s defaulting on past loans, inability to stabilise its own economy, and its inability to stem corruption and advance human rights.[151] In 2009, Zimbabwe abandoned its currency, relying instead on foreign currencies such as the South African rand, the US dollar, the Botswana pula, the euro and the British pound, among others.[154]

Zimbabwe‘s current per cap GDP is $1,054.

I think one of the common misconceptions about NRx is that it is based on a bunch of overly-pessimistic speculations about the future of democracy in places like the US or Germany. There’s plenty of that, of course. But much of Neoreaction is actually based on observation of events that have already happened in places like the DRC, Zimbabwe, and South Africa.

Chimpanzee family from the Gombe
Chimpanzee family from the Gombe

To be fair, though, we are getting really off track from our original mission of reviewing Jane Goodall’s book about chimpanzees. In the book’s Forward, David A. Hamburg writes:

The picture of chimpanzee life that emerges is fascinating. Here is a highly intelligent, intensely social creature capable of close and enduring attachments, yet nothing that looks quite like human love, capable of rich communication through gestures, posture, facial expressions, and sounds, yet nothing quite like human language. This is a creature who not only uses tools effectively but also makes tools with considerable foresight; a creature who does a little sharing of food, though much less than man; a creature gifted in the arts of bluff and intimidation, highly excitable and aggressive, capable of using weapons, yet engaging in no activity comparable to human warfare; a creature who frequently hunts and kills small animals of other species in an organized, cooperative way, and seems to have some zest for the process of hunting, killing, and eating the prey; a creature whose repertoire of acts in aggression, deference, reassurance, and greeting bear uncanny similarity to human acts in similar situations.

This bold turns out to be false.

In the Shadow of Man was published in 1971; the chimpanzees of the Kahama region of the Gombe Stream went to war against the chimps of Kasakala in 1974:

The two [groups] had previously been a single, unified community, but by 1974 researcher Jane Goodall, who was observing the community, first noticed the chimps dividing themselves into northern and southern sub-groups.[2]

The Kahama group, in the south, consisted of six adult males (among them the chimpanzees known to Goodall as “Hugh”, “Charlie”, and “Goliath”), three adult females and their young, and an adolescent male (known as “Sniff”).[2] The larger Kasakela group, meanwhile, consisted of twelve adult females and their young, and eight adult males.[2] …

The first outbreak of violence occurred on January 7, 1974,[4] when a party of six adult Kasakela males attacked and killed “Godi”, a young Kahama male …

Over the next four years, all six of the adult male members of the Kahama were killed by the Kasakela males.[5] Of the females from Kahama, one was killed, two went missing, and three were beaten and kidnapped by the Kasakela males.[5] The Kasakela then succeeded in taking over the Kahama’s former territory.[5]

I have the luxury of reading this account after already hearing, at least vaguely, that chimps wage war on each other. To Jane–despite having observed chimpanzee belligerence for years–it came as a surprise:

The outbreak of the war came as a disturbing shock to Goodall, who had previously considered chimpanzees to be, although similar to human beings, “rather ‘nicer'” in their behavior.[7] Coupled with the observation in 1975 of cannibalistic infanticide by a high-ranking female in the community, the violence of the Gombe war first revealed to Goodall the “dark side” of chimpanzee behavior.[7] She was profoundly disturbed by this revelation; in her memoir Through a Window: My Thirty Years with the Chimpanzees of Gombe, she wrote:

“For several years I struggled to come to terms with this new knowledge. Often when I woke in the night, horrific pictures sprang unbidden to my mind—Satan [one of the apes], cupping his hand below Sniff’s chin to drink the blood that welled from a great wound on his face; old Rodolf, usually so benign, standing upright to hurl a four-pound rock at Godi’s prostrate body; Jomeo tearing a strip of skin from Dé’s thigh; Figan, charging and hitting, again and again, the stricken, quivering body of Goliath, one of his childhood heroes. [8]”

War.

I suspect that humans evolved their upright stance to be better at carrying around large sticks with which to kill other apes. This made it harder for us to climb trees, but may have allowed for our voice boxes to descend (the voice box is actually important for closing off the lungs to provide rigidity to the chest while climbing,) allowing for a greater range of vocalizations, which in turn made us better at communicating and so organizing our bashing-apes-with-sticks expeditions. Eventually we stopped hunting other primates and turned our attention to more efficient game, like mammoths.

The big six civilizations (part 5: China, Treasure Ships, and Eunuchs)

ff23e2c73822050c646f06efd7503a4b

I doubt I need to tell you that China was one of the first six major, basically independent civilizations to emerge in world history, but it was surprisingly late compared to the others.

Anyway, this post is going to only briefly look at the Erlitou, as I assume you are already fairly familiar with Chinese culture, and instead focus on the voyages of the Treasure Ships. And eunuchs.

The Erlitou culture appeared on the Li river around 1900 BC. The largest city, also called Erlitou, may have been home to 18,000-30,000 people, before the capital got moved and most of the folks moved away. They may have been the somewhat mythical Xia dynasty, but there isn’t enugh evidence, yet, to prove the association either way.

The Erlitou people had pottery, (and potters’ wheels,) could smelt bronze, were making silk, and raising domesticated plants and animals such as wheat, rice, millet, pigs, and goats. (Rice was originally domesticated in south Asia, but had spread by this point to China.) I believe they also had some form of proto-writing.

They weren’t the first folks in the area–they succeeded the Longshan culture, which had small farming villages and probably morphed into the Erlitou–but they appear to be the first large polity.

Now that’s all well and good, but the interesting stuff came later.

The many helpful comments back on my post, the Hikikomori Nations, pointed me to the naval journeys of Zheng He, who commanded the Chinese navy, battled pirates, and sailed to Indonesia, India, and Africa back in 1405-1433.

Then, almost as suddenly as these “Treasure Voyages” had begun, they ended. Wikipedia explains why:

The treasure voyages were commanded and overseen by the eunuch establishment whose political influence was heavily dependent on imperial favor. However, within Ming China’s imperial state system, the civil government were the primary political opponents of the eunuchs and the opposing faction against the expeditions. Around the end of the maritime voyages, the civil government gained the upper hand within the state bureaucracy, while the eunuchs gradually fell out of favor after the death of the Yongle Emperor.

This left me scratching my head. Eunuchs were a political block in early 15th century China?

The Wikipedia page on Eunuchs helpfully explains:

In China, castration included removal of the penis as well as the testicles. …

From ancient times until the Sui Dynasty, castration was both a traditional punishment … and a means of gaining employment in the Imperial service. Certain eunuchs gained immense power that occasionally superseded that of even the Grand Secretaries. Zheng He, who lived during the Ming Dynasty, is an example of such a eunuch. Self-castration was a common practice, although it was not always performed completely, which led to its being made illegal.

It is said that the justification for the employment of eunuchs as high-ranking civil servants was that, since they were incapable of having children, they would not be tempted to seize power and start a dynasty.

*Mind boggles.*

Sun Yaoting, right, and his biographer, left
Sun Yaoting, right, and his biographer, left

The last Imperial eunuch, Sun Yaoting, died in December 1996.

Here’s an Australian article about poor Sun:

For centuries in China, the only men from outside the imperial family who were allowed into the Forbidden City’s private quarters were castrated ones. …

Sun’s impoverished family set him on this painful, risky path in hopes that he might one day be able to crush a bullying village landlord who stole their fields and burnt their house.

His desperate father performed the castration on the bed of their mud-walled home, with no anaesthetic and only oil-soaked paper as a bandage. A goose quill was inserted in Sun’s urethra to prevent it getting blocked as the wound healed.

He was unconscious for three days and could barely move for two months. When he finally rose from his bed, history played the first of a series of cruel tricks on him – he discovered the emperor he hoped to serve had abdicated several weeks earlier.

Sun was eight years old at the time.

The young ex-emperor was eventually allowed to stay in the palace and Sun had risen to become an attendant to the empress when the imperial family were unceremoniously booted out of the Forbidden City, ending centuries of tradition and Sun’s dreams.

“He was castrated, then the emperor abdicated. He made it into the Forbidden City then Pu Yi was evicted. He followed him north and then the puppet regime collapsed. He felt life had played a joke at his expense,” Jia said.

If you’re curious, Yinghua Jia wrote a whole book about Sun’s life, The Last Eunuch of China. (It has 4.5 stars.)

You know, growing up, I heard fairly frequently about Chinese foot-binding (done to women) and harems (in various countries.) There was a fairly frequent intellectual subcurrent of “historical cultures were mean to women.” NO ONE EVER MENTIONED THE EUNUCHS.

Okay, carrying on: so there were apparently enough men whose parents had thought it a good idea to lop of their genitals in order to get them a job that they constituted an opinion-making polity within the Chinese government, and got into conflicts with the Confucian scholars, who I assume hadn’t been horrifically mutilated by their parents.

The Treasure Voyages were thought up by the Eunuchs, and the admiral of the Treasure Fleet, Zheng He, was a eunuch:

Zheng He (1371–1433 or 1435), often spelled Cheng Ho in English, was a Hui court eunuch, mariner, explorer, diplomat, and fleet admiral during China‘s early Ming dynasty. Born Ma He, Zheng commanded expeditionary voyages to Southeast Asia, South Asia, Western Asia, and East Africa from 1405 to 1433. …

As a favorite of the Yongle Emperor, whose usurpation he assisted, he rose to the top of the imperial hierarchy and served as commander of the southern capital Nanjing (the capital was later moved to Beijing by the Yongle Emperor). …

Zheng He was born into a Muslim family.[7][10][11]

He was a great-great-great-grandson of Sayyid Ajjal Shams al-Din Omar, a Persian who served in the administration of the Mongol Empire and was the governor of Yunnan during the early Yuan dynasty.[14][15] His great-grandfather was named Bayan and may have been stationed at a Mongol garrison in Yunnan.[7] His grandfather carried the title hajji.[1][16] His father had the surname Ma and the title hajji.[1][7][16] The title suggests that they had made the pilgrimage to Mecca.[1][7][16] It also suggests that Zheng He may have had Mongol and Arab ancestry and that he could speak Arabic.[17]

Zheng He had a distinguished career in the army before becoming head of the Chinese navy.

It is generally accepted (based on Ming dynasty records) that Zheng He died in 1433 at Calicut in India during the return leg of the seventh voyage and was buried in Calicut or at sea,[48] although some theories, based on artifacts associated with him and believed to be from later than 1433, posit that he died shortly after that voyage in 1434[48] or early 1435.[49]

A tomb was built for Zheng He in Nanjing. This is usually believed to be a cenotaph containing his clothes and headgear as his body was buried at sea or in Calicut, but other theories exist as to whether Zheng He was buried in Nanjing, and if so, where. In 1985, a Muslim-style tomb was built on the site of the earlier horseshoe-shape grave.[50] He adopted the eldest son of his elder brother, who was awarded a hereditary officer rank in the imperial guard.

The voyages of Zheng He
The voyages of Zheng He

As for the Treasure Fleet itself:

The grand project resulted in seven far-reaching ocean voyages to the coastal territories and islands in and around the South China Sea, the Indian Ocean, and beyond. … The first three voyages reached up to Calicut on India’s southwestern coast, while the fourth voyage went as far as Hormuz in the Persian Gulf. Afterwards, the fleet made voyages farther away to the Arabian Peninsula and East Africa.

While the voyages did result in better maps, they weren’t exploratory, like Columbus’s–the Chinese were already well aware that India and Africa existed before they set out:

Chinese seafaring merchants and diplomats of the medieval Tang Dynasty (618—907) and Song Dynasty (960—1279) often sailed into the Indian Ocean after visiting ports in South East Asia. Chinese sailors would travel to Malaya, India, Sri Lanka, into the Persian Gulf and up the Euphrates River in modern-day Iraq, to the Arabian peninsula and into the Red Sea, stopping to trade goods in Ethiopia and Egypt (as Chinese porcelain was highly valued in old Fustat, Cairo).[11] Jia Dan wrote Route between Guangzhou and the Barbarian Sea during the late 8th century that documented foreign communications, the book was lost, but the Xin Tangshu retained some of his passages about the three sea-routes linking China to East Africa.[12] Jia Dan also wrote about tall lighthouse minarets in the Persian Gulf, which were confirmed a century later by Ali al-Masudi and al-Muqaddasi.[13] Beyond the initial work of Jia Dan, other Chinese writers accurately described Africa from the 9th century onwards; For example, Duan Chengshi wrote in 863 of the slave trade, ivory trade, and ambergris trade of Berbera, Somalia.[14] Seaports in China such as Guangzhou and Quanzhou – the most cosmopolitan urban centers in the medieval world – hosted thousands of foreign travelers and permanent settlers. Chinese junk ships were even described by the Moroccan geographer Al-Idrisi in his Geography of 1154, along with the usual goods they traded and carried aboard their vessels.[15]

Nor was trade the main point, because Chinese merchants were already doing plenty of trade. Rather:

The Chinese expeditionary fleet was heavily militarized and carried great amounts of treasures, which served to project Chinese power and wealth to the known world. They brought back many foreign ambassadors whose kings and rulers were willing to declare themselves tributaries of China. During the course of the voyages, they destroyed Chen Zuyi‘s pirate fleet at Palembang, conquered the Sinhalese Kotte kingdom of King Alekeshvara, and defeated the forces of the Semudera pretender Sekandar in northern Sumatra.

There is some debate about exactly how big the Treasure Ships were, but the general consensus appears to be that they were some of (if not the) biggest in the world at the time, and carried about 27,000 people. (Total, not per boat.)

Due to bad record keeping (more on this later,) there is some debate (or spirited fantasy) about where, exactly, Zheng He (and other Chinese admirals) sailed:

He is best known for his controversial book 1421: The Year China Discovered the World, in which he asserts that the fleets of Chinese Admiral Zheng He visited the Americas prior to European explorer Christopher Columbus in 1492, and that the same fleet circumnavigated the globe a century before the expedition of Ferdinand Magellan. …

Menzies states in the introduction that the book is an attempt to answer the question:

On some early European world maps, it appears that someone had charted and surveyed lands supposedly unknown to the Europeans. Who could have charted and surveyed these lands before they were ‘discovered’?

In the book, Menzies concludes that only China had the time, money, manpower and leadership to send such expeditions and then sets out to prove that the Chinese visited lands unknown in either China or Europe. He claims that from 1421 to 1423, during the Ming dynasty of China under the Yongle Emperor, the fleets of Admiral Zheng He, commanded by the captains Zhou Wen, Zhou Man, Yang Qing, and Hong Bao, discovered Australia, New Zealand, the Americas, Antarctica, and the Northeast Passage; circumnavigated Greenland, tried to reach the North and South Poles, and circumnavigated the world before Ferdinand Magellan.

Unfortunately, it looks like Menzies massively over-reached and doesn’t provide much proof, as many of his reviewers point out.

Our original question that started this whole quest was whether the Chinese discovered Australia (or New Zealand) before the Europeans. (And not Taiwanese-descended Polynesians, who obviously got to NZ first.)

According to Mega-Tsunamis, Chinese Junks, and Port Philip Bay (a very speculative article linked in the comments on the original post):

In 1450 AD, the catastrophic comet Mahuika descended upon the coast of New Zealand. Reputed to be twenty-six times as bright as the Sun, it discharged electrically and shattered Admiral Zhou Man’s Chinese fleet of some sixty ships. The fleet supported a thriving Chinese colony of Han, Tang and Song, mining gold, jade and antimony in New Zealand. The comet’s screaming noise blew out the sailors’ eardrums; they received horrific burns. …

These facts are recorded in the meticulous fifteenth century records of Chinese ambassador Zheng He. Historian Gavin Menzies claims that over nine hundred ships failed to return to China from Pacific expeditions in that tragic year.

I don’t know how much of this comes directly from Menzies’ work vs. other peoples’ speculations, but since Zheng He died in 1433 (or maybe 1435, at the latest,) I don’t think he was writing very much about comets in 1450. Further, I find it unlikely that Admiral Zhou Man was commanding a fleet of Chinese ships in 1450, given that the last Treasure Voyages ended in 1433, after which official Chinese sentiment turned against the voyages and the ships were left to rot in their docks. Wikipedia notes:

In the Ming court, the civil officials were the faction who were against the voyages.[143][156][168] In contrast, the eunuch establishment stood at the head of the fleet and the expeditions.[140][141][156][168] The civil officials condemned the expeditions as extravagant and wasteful.[168][169] Traditionally, they were political opponents of the eunuch establishment,[140][156][168] but also to the military establishments who crewed the fleet.[156] … On cultural grounds, the hostility came forth due to the trade and acquisition of strange foreign goods which stood in contrast to their Confucian ideologies.[171][172][168][169] The undertaking of these expeditions only remained possible as long as the eunuchs maintained imperial favor.[141][173]

The Hongxi Emperor was fiercely against the treasure voyages throughout his reign.[80] After the advice of Xia Yuanji, he ordered the cessation of the treasure voyages on 7 September 1424, the day of his accession to the throne.[93]

After 1433, the civil officials succeeded in halting subsequent maritime expeditions.[170] The ships were left to rot, while their lumber was sold for fuel in Nanjing.[170] The mariners were reassigned to load grain on barges of the Grand Canal and to build the emperor’s mausoleum.[170] After the voyages, subsequent Ming emperors would reject the Yongle Emperor’s policy of bringing the maritime trade into the structure of the tributary system.[140]

It also looks like there was some effort to suppress or destroy records of the voyages, (leaving ample room for folks like Menzies to speculate on what might be missing,) so that future leaders wouldn’t get the wrong idea and try to recreate them.

Further:

From 1405 to 1433, large fleets commanded by Admiral Zheng He—under the auspices of the Yongle Emperor of the Ming Dynastytraveled to the Indian Ocean seven times. This attempt did not lead China to global expansion, as the Confucian bureaucracy under the next emperor reversed the policy of open exploration and by 1500, it became a capital offence to build a seagoing junk with more than two masts.[16] Chinese merchants became content trading with already existing tributary states nearby and abroad. To them, traveling far east into the Pacific Ocean represented entering a broad wasteland of water with uncertain benefits of trade.

While trade continued, official support and imperial navies did not, largely justified by the Haijin doctrine, which banned maritime shipping in 1371 and enforced to varying degrees over the years:

In the second month of the first year (1661) of Kangxi, the Qing court issued an imperial decree: The sea shore inhabitants will be ordered to move inland 50 li, to curb their links with the Taiwan rebels under Koxinga. Soldiers then moved in and set up the boundary: in just three days, all houses were razed to the ground and all inhabitants evacuated. … Warnings were placed on notice boards stating that “Anyone who dares to step over the border line shall be beheaded!” “Persons found a few paces over the border line, shall be beheaded instantly.”

This is, however, well after the time period we are discussing. It looks like the main reason the Treasure Voyages were canceled (aside from eunuchs vs. Confucian conflicts) is that the Mongols became a problem (the Mongols were frequently a problem, after all,) and China had to devote its energies to defending its land borders rather than sailing about the ocean.

Perhaps the best evidence either way would be maps:

Gangnido map
Gangnido map
Selden Map
Selden Map
page from the Mao Kun map, showing the South China Sea with Paracel and Spratly Islands
A page from the Mao Kun map, showing the South China Sea with Paracel and Spratly Islands

These are the maps I’ve found so far, none of which show Australia or New Zealand. The Mao Kun map is supposed to be based of Zheng He’s maps, and is divided into 40 pages, showing the coasts of China, India, east Africa, etc.

The Seldon Map, from the early 1600s, while very good, does not show Australia, and the Gangnido map (and its later, updated copies,) which people think may show the Arabian peninsula, Africa, the Mediterranean, and part of Europe on its left side, (but strangely, the Malay Peninsula and India were smooshed together into the left-hand side of the big China blob, according to the Wikipedia talk page.)

At any rate, it looks like Australia and New Zealand didn’t make it onto the maps until much later–if they were known to the Chinese, they were probably regarded as unimportant due to lack of valuable trade goods or political states to trade ambassadors with.

I find the difference between the official Chinese reaction to the Treasure Voyages and the European reaction to Columbus’s discoveries remarkable.
