Re: Chauncey Tinker on Dysgenics

By request, I am responding to Chauncey Tinker’s posts on dysgenics:

Dysgenics and Welfare and Dysgenics and Solutions.

To summarize, our current generous welfare system is making it increasingly difficult for hard working members of society to afford to have children. Lazy and incapable people meanwhile are continuing to have children without restriction, courtesy of those hard working people. Its more than likely that average intelligence is falling as a result of these pressures.

Ever since someone proposed the idea of eguenic (ie, good) breeding, people have been concerned by the possibility of dysgenic (bad) breeding. If traits are heritable (as, indeed, they are,) then you can breed for more of that trait or less of that trait. Anyone who has ever raised livestock or puppies knows as much–the past 10,000 years of animal husbandry have been devoted to producing superior stock, long before anyone knew anything about “genes.”

Historically–that is, before 1900–the world was harsh and survival far from guaranteed. Infant and childhood mortality were high, women often died in childbirth, famines were frequent, land (in Europe) was scarce, and warfare + polygamy probably prevented the majority of men from ever reproducing. In those days, at least in Western Europe, the upper classes tended to have more (surviving) children than the lower classes, leading to a gradual replacement of the lower classes.

The situation today is, obviously, radically different. Diseases–genetic or pathogenic–kill far fewer people. We can cure Bubonic Plague with penicillin, have wiped out Smallpox, and can perform heart surgery on newborns whose hearts were improperly formed. Welfare prevents people from starving in the streets and the post-WWII prosperity led to an unprecedented percent of men marrying and raising families. (The percent of women who married and raised families probably didn’t change that much.)

All of these pleasant events raise concerns that, long-term, prosperity could result in the survival of people whose immune systems are weak, carry rare but debilitating genetic mutations, or are just plain dumb.

So how is Western fertility? Are the dumb outbreeding the smart, or should we be grateful that the  “gender studies” sorts are selecting themselves out of the population? And with negative fertility rates + unprecedented levels of immigration, how smart are our immigrants (and their children?)

Data on these questions is not the easiest to find. Jayman has data on African American fertility (dysgenic,) but white American fertility may be currently eugenic (after several decades of dysgenics.) Jayman also notes a peculiar gender difference in these trends: female fertility is strongly dysgenic, while male is eugenic (for both whites and blacks). Given that historically, about 80% of women reproduced vs. only 40% of males, I think it likely that this pattern has always been true: women only want to marry intelligent, high-performing males, while males are okay with marrying dumb women. (Note: the female ability to detect intelligence may be broken by modern society.)

Counter-Currents has a review of Lynn’s Dysgenics with some less hopeful statistics, like an estimation that Greece lost 5 IQ points during the Baby Boom, which would account for their current economic woes. (Overall, I think the Baby Boom had some definite negative effects on the gene pool that are now working their way out.)

Richwine estimates the IQ of our immigrant Hispanic-American population at 89.2, with a slight increase for second and third-generation kids raised here. Since the average American IQ is 98 and Hispanics are our fastest-growing ethnic group, this is strongly dysgenic. (The rest of our immigrants, from countries like China, are likely to be higher-IQ than Americans.) However, since Hispanic labor is typically used to avoid African American (reported 85 average IQ) labor, the replacement of African Americans with Mexicans is locally eugenic–hence the demand for Hispanic labor.

Without better data, none of this conclusively proves whether fertility in the West is currently eugenic or dysgenic, but I can propose three main factors that should be watched for their potentially negative effects:

  1. Immigration (obviously.)
  2. Welfare–I suspect the greater black reliance on welfare may be diving black dysgenics, but some other factor like crime could actually be at play.
  3. Anti-child culture.

I’m going to focus on the last one because it’s the only one that hasn’t already been explained in great detail elsewhere.

For American women, childbearing is low-class and isolating.

For all our fancy talk about maternity leave, supporting working moms, etc., America is not a child-friendly place. Society frowns on loud, rambunctious children running around in public, and don’t get me started on how public schools deal with boys. Just try to find something entertaining for both kids and grown-ups that doesn’t cost an arm and a leg for larger families–admission to the local zoo for my family costs over $50 and requires over an hour, round trip, of driving. (And it isn’t even a very good zoo.) Now try to find an activity your childless friends would also like to do with you.

Young women are constantly told that getting pregnant will ruin their lives (most vocally by their own parents,) and that if they want to stay home and raise children, they are social parasites. (Yes, literally.) We see child-rearing, like tomato picking, as a task best performed by low-wage immigrant daycare workers.

I am reminded here of a mom’s essay I read about the difference in attitudes toward children in the US and Israel, the only Western nation with a positive native fertility rate. Israel, as she put it, is a place where children are valued and “kids can be kids.” I’ve never been to Israel, so I’ll just have to trust her:

How Israelis love kids, anyone’s kids. The country is a free-for-all for the youngest set, something I truly appreciated only once I started bringing my own children there. When I was a teenager visiting Israel from the States, I noticed how people there just don’t allow a child to cry. One pout, one sob, and out comes candy, trinkets and eager smiles to turn a kid around. That would never happen back home—a stranger give a child candy?!—but in Israel, in a nation that still harbors a post-Holocaust mentality, there is no reason that a Jewish child should ever cry again, if someone can help it.

Incidentally, if you qualify under Israeli health care law, you can get a free, state-funded abortion. Abortion doesn’t appear to have destroyed Israel’s fertility.

Since male fertility is (probably) already eugenic, then the obvious place to focus is female fertility: make your country a place where children are actively valued and intelligent women are encouraged instead of insulted for wanting them, and–hopefully–things can improve.

Comments on Chauncey Tinker’s Intelligence, Concentration, and IQ Tests

A while back, Chauncey Tinker wrote a post on Intelligence, Concentration, and IQ Tests:

I do not believe that IQ tests measure intelligence. Rather I believe that they measure a combination of intelligence, learning and concentration at a particular point in time. …

You may wish to read the whole thing there.

The short response is that I basically agree with the bit quoted, and I suspect that virtually everyone who takes IQ tests seriously does as well. We all know that if you come into an IQ test hungover, sick, and desperately needing to pee, you’ll do worse than if you’re well-rested, well-fed, and feeling fine.

That time I fell asleep during finals?

Not so good.

Folks who study IQ for a living, like the famous Flynn, believe that environmental effects like the elimination of leaded gasoline and general improvements in nutrition have raised average IQ scores over the past century or two. (Which I agree seems pretty likely.)

The ability to sit still and concentrate is especially variable in small children–little boys are especially notorious for preferring to run and play instead of sit at a desk and solve problems. And while real IQ tests (as opposed to the SAT) have been designed not to hinge on whether or not a student has learned a particular word or fact, the effects of environmental “enrichment” such as better schools or high-IQ adoptive parents do show up in children’s test scores–but fade away as children grow up.

There’s a very sensible reason for this. I am reminded here of an experiment I read about some years ago: infants (probably about one year old) were divided into two groups, and one group was taught how to climb the stairs. Six months later, the special-instruction group was still better at stair-climbing than the no-instruction group. But two years later, both groups of children were equally skilled at stair-climbing.

There is only so good anyone will ever get at stair-climbing, after all, and after two years of practice, everyone is about equally talented.

The sensible conclusion is that we should never evaluate an entire person based on just one IQ test result (especially in childhood.)

The mistake some people (not Chuancey Tinker) make is to jump from “IQ tests are not 100% reliable” to “IQ tests are meaningless.” Life is complicated, and people like to sort it into neat little packages. Friend or foe, right or wrong. And while single IQ test is insufficient to judge an entire person, the results of multiple IQ tests are fairly reliable–and if we aggregate our results over multiple people, we get even better results.

As with all data, more tests + more people => random incorrect data matters less.

I think the “IQ tests are meaningless” crowd is operating under the assumption that IQ scholars are actually dumb enough to blindly judge an entire person based on a single childhood test. (Dealing with this strawman becomes endlessly annoying.)

Like all data, the more the merrier:

Thanks to Jayman
Thanks to Jayman

So this complicated looking graph shows us the effects of different factors on IQ scores over time, using several different data sets (mostly twins studies.)

At 5 years old, “genetic” factors, (the diamond and thick lines) are less important than “shared environment.” Shared environment=parenting and teachers.

That is, at the age of 5, a pair of identical twins who were adopted by two different families will have IQ scores that look more like their adoptive parents’ IQ scores than their genetic relatives’ IQ scores. Like the babies taught to climb stairs before their peers, the kids whose parents have been working hard to teach them their ABCs score better than kids whose parents haven’t.

By the age of 7, however, this parenting effect has become less important than genetics. This means that those adopted kids are now starting to have IQ scores more similar to their biological relatives than to their adoptive relatives. Like the kids from the stair-climbing experiment, their scores are now more based on their genetic abilities (some kids have better balance and coordination, resulting in better stair-climbing) than on whatever their parents are doing with them.

By the age of 12, the effects of parenting drop to around 0. At this point, it’s all up to the kid.

Of course, adoption studies are not perfect–adoptive parents are not randomly selected and have to go through various hoops to prove that they will be decent parents, and so tend not to be the kinds of people who lock their children in closets or refuse to feed them. I am sure this kind of parenting does terrible things to IQ, but there is no ethical way to design a randomized study to test them. Thankfully, the % of children subject to such abysmal parenting is very low. Within the normal range of parenting practices, parenting doesn’t appear to have much (if any) effect on adult IQ.

The point of all this is that what I think Chauncey means by “learning,” that is, advantages some students have over others because they’ve learned a particular fact or method before the others do, does appear to have an effect on childhood IQ scores, but this effect fades with age.

I think Pumpkin Person is fond of saying that life is the ultimate IQ test.

While we can probably all attest to a friend who is “smart but lazy,” or smart but interested in a field that doesn’t pay very well, like art or parenting, the correlation between IQ and life outcomes (eg, money) are amazingly solid:

The correlation even holds internationally:

I do wonder why he made the graph so much bigger than the relevant part
Lifted gratefully from La Griffe Du Lion’s Smart Fraction II article

There’s a simple reason why this correlation holds despite lazy and non-money-oriented smart people: there are also lazy and non-money-oriented dumb people, and lazy smart people tend to make more money and make better long-term financial decisions than lazy dumb people.

Note that none of these graphs are the result of a single test. A single test would, indeed, be useless.

Maps, maps, maps (pt. 2/2: Australia)

Guillaume Brouscon world map, 1543
Guillaume Brouscon world map, 1543

Yes, the answer to Tuesday’s final query is that the Dieppe maps, (including Guillaume Brouscon’s,) show a great big landmass almost exactly where Australia actually is, a good 50 or 60 years before the first documented European sighting. (By Dutch navigator Willem Janszoon, in 1606.)

800px-Australia_discoveries_by_Europeans_before_1813_enThere’s this funny gap in human knowledge of Australia. 50,000 years ago, humans equipped with little more than sharp rocks and pointy sticks managed to get to Australia and make themselves home. Then, for the next 49,500 or so years, everyone else forgot that it was there. (Aside from a few lost souls from India who washed up, IIRC, abut 10,000 years ago.) (It looks like the southern coast of Australia wasn’t even explored [by sea,] until 1801.)

Even China, an organized polity with excellent record-keeping, ship-making, and map-making skills going back centuries, does not show Australia on its maps (at least not on any map I’ve found,) until 1602.

1602 is still before 1606, but we will discuss these Chinese maps in a minute.

Portugal had a policy, in the 1500s, of treating its nautical maps as official state secrets. French spies, therefore, went and bribed Portuguese map-makers into sharing their secrets, the results of which are probably the Dieppe maps, due to their many Portuguese and French labels, indicating French cartographers working off Portuguese originals.

All of which raises the question of WHO was exploring Australia in the early 1500s. Was it the Portuguese? If so, they’ve done an excellent job (a few bribed cartographers aside,) in keeping it secret. Unlike the fabled Viking settlement in Vinland, we have yet to discover any hard evidence, such as Portuguese DNA or artifacts in Australia, that would confirm an early Portuguese presence.

The “Australia” landmass on the Dieppe maps is labeled “Jave la Grande.” Wikipedia claims that this name comes from Marco Polo:

“As explained by Sir Henry Yule, the editor of an English edition of Marco Polo’s travels: “Some geographers of the 16th century, following the old editions which carried the travellers south-east of Java to the land of Boeach (or Locac), introduced in their maps a continent in that situation”.[3]”

Behaim's Erdapfel globe, 1492
Behaim’s Erdapfel globe, 1492

The problem with this explanation is that in the two and a half centuries of map-making between the publication of Marco Polo’s adventures and the drawing of the Dieppe maps, no one stuck in a giant continental blob of land south of Indonesia, labeled “Jave la Grande” nor anything else. Jave la Grand does show up on some of these maps, but as a quite ordinary island about where you’d expect it. EG, the Erdapfel globe of 1492 (too early to include Columbus’s discoveries, which weren’t known until 1493, but definitely disproving the idea that people in Columbus’s day thought the world was flat.)

I find it highly unlikely that the Dieppe cartographers suddenly decided to turn “Jave la Grande” into a great big landmass in a spot where no prior European maps had ever shown land, and happened, totally by accident, to position it where there actually is a continent.

The Erdpafel's depiction of the Pacific, including Java Major
The Erdpafel’s depiction of the Pacific, including Java Major (aka Java la Grande)

It seems far more likely that they were working off charts that happened to show a large landmass in this spot, and needing a name for it, they chose the closest thing they could find in Marco Polo’s account. (I would not worry about the location being slightly off, due to these maps predating our ability to find longitude at sea by over a hundred years.)

That leaves the question of how Australia got on the charts. Just as the French got their information from the Portuguese, the Portuguese may have gotten their information, in turn, from someone else, like the Chinese, Indonesians, or Islamic mariners.

The Wikipedia page on Islamic geography is inadequate for me to draw any conclusions from it.

Japanese copy of Matteo Ricci's Kunyu Wanguo Quantu world map
Japanese copy of Matteo Ricci’s Kunyu Wanguo Quantu world map

As I mentioned earlier, the first Chinese maps (that I know of) to show Australia are from 1602, after the Dieppe maps. The Kunyu Wanguo Quantu were created by Matteo Ricci, an Italian Jesuit missionary. The Kunyu Wanguo Quantu combines, for the first time, the geographic knowledge of Europe and China.

Sancai Tuhui World Map
Sancai Tuhui World Map, the Shanhai Yudi Quantu, of 1609

Ricci got to China by hopping aboard a Portuguese vessel, which dropped him off at their colony in Goa. From there he traveled to Macau, and then to Beijing and the Forbidden City (though he never met the Emperor.) So I think it highly likely that Ricci had access to (or knowledge of) Portuguese maps/discoveries, or the Dieppe maps themselves. I suspect that Ricci’s knowledge of Australia did not come from Chinese sources, because the Chinese world map Shanhai Yudi Quantu, (1609,) though inspired by Ricci’s work, does not show Australia.

The Indonesians are another potential source. I don’t know anything about the history of Indonesian map-making, but the Wikipedia page on the prehistory of Australia intriguingly informs us:

…the people living along the northern coastline of Australia, in the Kimberley, Arnhem Land, Gulf of Carpentaria and Cape York had encounters with various visitors for many thousands of years. People and traded goods moved freely between Australia and New Guinea up to and even after the eventual flooding of the land bridge by rising sea levels …

Indonesian “Bajau” fishermen from the Spice Islands (e.g. Banda) have fished off the coast of Australia for hundreds of years. Macassan traders from Sulawesi regularly visited the coast of northern Australia to fish for trepang, an edible sea cucumber to trade with the Chinese since at least the early 18th century. Tamil sea-farers also had knowledge of Australia and Polynesia before European contact.[37] …

The myths of the people of Arnhem Land have preserved accounts of the trepang-catching, rice-growing Baijini people, who, according to the myths, were in Australia in the earliest times, before the Macassans. …

In 1944, a small number of copper coins with Arabic inscriptions were discovered on a beach in Jensen Bay on Marchinbar Island, part of the Wessel Islands of the Northern Territory. These coins were later identified as from the Kilwa Sultanate of east Africa. Only one such coin had ever previously been found outside east Africa (unearthed during an excavation in Oman).

Ruysch Map
Ruysch Map

So it is possible that the accounts of any of these folks could have made it onto local maps, and made their way from there to the Portuguese and the Dieppe maps (though I will note that if the Macassans got there in the 18th century, that is after the Dieppe maps, but I don’t know how exact that date is.)

There is, however, a potentially more mundane explanation for this odd landmass: it could just be South America. To European mapmakers of the late 14 and early 1500s, it was not at all clear that Columbus had discovered the edge of a new continent, rather than some islands off the coast of Asia–hence Ruysch’s 1507 map that show Massachusetts merging into China.

Mercator map of 1595 showing Hy-Brasil and an extra Iceland
Mercator map of 1595 showing Hy-Brasil and an extra Iceland

In the days before mariners could easily check their longitude at sea, the location of various islands could only be estimated by calculating the direction and speed the ship that had reached them had been going, eg, “Three days’ sail to the West.” This meant that islands could appear in different spots on different maps, which sometimes resulted in islands getting duplicated in maps created by compiling several earlier charts. Iceland, for example, shows up twice on this map:

I think it possible, therefore, that the Dieppe map makers had before them one map which showed the coast of Brazil as an island near Indonesia, and a second map showed it as part of a continent in between Europe and Asia, and simply recorded both on their combined map. Personally, I think the shape of Jave la Grande looks more like South America than Australia, but perhaps if I could read thee maps or examine them in more detail, I would revise that assessment.

Beatus T-O style Map showing the antipodes, 1050
Beatus T-O style Map showing the antipodes on the far right, AD 1050

This would be a case of the Dieppe map makers getting lucky, not unheard of phenomenon. Medieval Europeans believed, for example, in a mythical “fourth continent” located on the other side of the world, called fanciful names like “the antipodes” (“the backwards feet,” a reference to the amusing idea that people on the other side of the world are standing upside down relative to oneself–again, proof that Europeans well before Columbus knew the Earth is round;) or less fancifully, “terra australis,” “southern land.” Since the Bible commands Christ’s disciples to spread his Gospel to “the four corners of the Earth,” Medieval mapmakers, faced with only 3 continents, figured there had to be a fourth. But since philosophical opinions conflicted regarding this fourth continent, it was not always included on maps.

The European age of exploration pushed the borders of this fourth continent increasingly southward, as the vast expanse of the Pacific, Indian, and Atlantic oceans were found not to harbor it, until it was restricted to the area south of South America. But here folks got lucky, and spotted an actual continent right where their maps said there ought to be one. Likewise, when Australia first showed up on European maps, it was supposed to be a northern promontory of this most southerly land, and so depicted. Thus the name “Terra Australis” came to be inscribed on this territory.

So we are still left with a mystery: did someone actually map Australia before the Dutch, or did the Dieppe map makers just get lucky?

 

Maps Maps Maps: A short history (pt 1/2)

Mercator map of 1595 showing Hy-Brasil and an extra Iceland
Mercator map of 1595 showing Hy-Brasil and an extra Iceland

Old maps are full of curiosities, like completely mythical islands (eg, Hy-Brasil,) land masses radically out of place or duplicated, and massive changes in scale from one side to the other.

Historical map-makers had three main problems: 1. They couldn’t measure longitude, 2. Their maps were often based on compilations of lots of maps from many different sources, often resulting in confusion, and 3. Some groups were more wiling to share their maps than others. (For example, there are lots of questions about what exactly the Portuguese knew in the 14 and 1500s, like rumors that Portuguese fishermen were secretly hauling in cod off the coast of Massachusetts–more on the Portuguese later.)

c5933People generally made good maps of their local areas fairly early on–the Chinese have some excellent early early maps, for example. But beyond the immediate and local, maps quickly became less detailed and more stylized, as in this “T-O” style medieval map, which obviously is not even trying to be accurate, but to express a theologic point.

Since early sailors did not usually strike out over long stretches of open water, but headed to nearby ports or islands a few days’ sail away, I suspect that most early sea charts put a great deal of effort into describing the relevant rocky shoals to avoid and safe harbors to take advantage of, and not so much effort into describing the broad curve of continental coastlines.

While latitude can be fairly easily measured by simply measuring the height of the North Star in degrees (if you are at the equator, the North Star will lie on the horizon; if you are at 45 degrees north, the North Star will be 45 degrees high in the sky;  if you are at the North Pole, the North Star will be directly above you, or 90 degrees. If you can’t find the North Star, you’re south of the equator.) (Wyrd Smythe explains in more detail if you are confused.)

But there is no easy, low-tech way to determine longitude, your east-west position on the Earth’s surface. Longitude is not a huge deal when island-hopping short distances, but it becomes a huge deal once you’re undertaking multi-week trans-Atlantic or trans-Pacific voyages, where a storm can suddenly blow you days off course and you end up crashing into rocks you didn’t know were there. For example, in 1707, four British Navy warships were pushed off course by storms off the coast of England and crashed into the Isles of Scilly. 1,550 sailors drowned, prompting the British government to offer a 20,000 pound prize for anyone who could figure out a way to accurately determine longitude at sea.

Recreation of Ptolemy’s world map

The lack of knowledge and inability to make good measurements rendered even the best early maps of the world objectively terrible.

Here we have a reconstruction of Ptolemey’s world map, based on the geographical knowledge of AD 150, and Al Idrisi’s map drawn for Roger II of Sicily in 1154. Idrisi did a good job depicting Sicily, but nearby Italy is a complete mess, and he duplicates Ptolemy’s mistake of essentially depicting India as a big island (actually, probably confusion between the size of India vs. the size of Sri Lanka,) and Ptolemy’s complete confusion about the angle of Africa’s east coast.

Tabula Rogeriana, created by Al-Idrisi

Al Idrisi did know about the Pacific ocean and the east Coast of China, which Ptolemy did not, but his geography of Denmark and Britain are worse than Ptolemy’s, despite having been based in Europe while working.The lack of advancement in geographic knowledge available in the Mediterranean over 1,000 years is striking (though I would not be surprised to find out that folks were working with much better maps of local currents and shoals in their areas than their ancestors had been using in Ptolemy’s time.)

Gangnido map
Gangnido map

On the other side of the world, Chinese and Korean maps show a similar pattern. The Gangnido (aka Kangnido,) map of 1402, created in Korea, shows Korea, China, the Arabian Peninsula, and Africa. I think India is very slightly projecting from the lower-left side of the China blob, with Sri Lanka a bit more properly sized than on Ptolemy’s map.

The Gangnido map is based on an earlier Chinese map, the Da Ming Hun Yi Tu of 1398, which is very similar, but might have the Malay Peninsula.

Now, you might be thinking, as I did, that “Africa” and “Arabia” look a lot like India on this map. Wikipedia assures us that they aren’t and offers this explanation, especially since it is difficult for us non-Koreans to read the map: 300px-KangnidoPoliticalDetails

But the total lack of a Malay peninsula is really confusing, as I assume anyone traveling from China to India would be quite are of this enormous detour in their way. It’s like drawing a map of Europe and leaving off Spain.

These maps show the difficulties of trying to compile one map out of many, as your maps may use vastly different scales. The Gangnido and Da Ming Hun Yi Tu maps combine information compiled from Chinese, Korean, Japanese, Mongolian (the Mongol empire collected maps from all of its conquered nations,) and Islamic sources, eg, the voyages of Ibn Battuta.

I have noticed that no matter which explorer of south Asia we are talking about, whether Ibn Battuta, Marco Polo, Zheng He, or the Polynesians, none of them seem to have made it to Australia.

Neither do any of these early (1400s or before) maps seem to show Australia–in other words, the Chinese (and Koreans) were drawing recognizable maps of Africa and Europe before Australia.

Guillaume Brouscon world map, 1543
Guillaume Brouscon world map, 1543

European portolan charts appeared, seemingly ex nihilo, in the 13th century. The portolans used compass directions plus sailing directions to estimate distances between map points, thus producing a revolution in map accuracy. The compass roses are drawn directly onto the map for navigational convenience, as on this “Dieppe map” by Guillaume Brouscon, 1543.

It is getting late, so I am going to have to continue this on Thursday, when we will discuss the Dieppe maps in some depth. But let me know if you catch the most curious thing about them.😉

 

 

When did Whites Evolve?

Defining exactly who is white is contentious and difficult–so I shan’t. If you want to debate among yourselves whether or not the Irish or Hindus count, that’s your own business.

Picture 1 Picture 2

Here’s Haak et al’s full graph of human genomes from around the world, (see here and here for various discussions.) The genomes on the far left are ancient European skeletons; everything from the “pink” section onward is modern. The “African” genomes all have bright blue at their bottoms; Asian (and American Indian) genomes all have yellow. The European countries tend to have a triple-color profile, reflecting their recent (evolutionarily speaking) mix of European hunter-gatherers (dark blue), Middle Eastern farmers (orange), and a “teal” group that came in with the Indo-European speakers, but whose origins we have yet to uncover:

Europe

Unsurprisingly, the Basque have less of this “teal.” Middle Easterners, as you can see, are quite similar genetically, but tend to have “purple” instead of “dark blue”

1024px-PSM_V52_D323_Global_hair_texture_mapPhysically, of course, whites’ most distinctive feature is pale skin. They are also unique among human clades in their variety of hair and eye colors, ranging from dark to light, and tend to have wavy hair that is “oval” in cross-section. (Africans tend to have curly hair that is flat in cross section, and Asians tend to have straight hair that is cylindrical in cross section. See map for more hair details.)

There are other traits–the Wikipedia page on “Caucasian race” (not exactly synonymous with “whites”) notes:

According to George W. Gill and other modern forensic anthropologists, physical traits of Caucasoid crania are generally distinct from those of the Mongoloid and Negroid races. They assert that they can identify a Caucasoid skull with an accuracy of up to 95% by the following features: [20][21][22][23][24]

  • An orthognathic profile, with minimal protrusion of the lower part of the face (little or no prognathism).
  • Retreating zygomatic bones (cheekbones), making the face look more “pointed”.
  • Narrow nasal aperture, with a tear-shaped nasal cavity (nasal fossa).

Bodyhair_map_according_to_American_Journal_of_Physical_Anthropology_and_other_sourcesBut I am not going to deal with any of these, unless I hear of something like the EDAR gene coding for a bunch of traits.

Old racial classifications made use of language groups as stand-ins for racial groups. This turns out to be not very reliable, as we’ve found that in many cases, a small group of conquerors has managed to impose its language without imposing its genetics, as you’ve discovered in real life if you’ve ever met an African or Indian who speaks English.

europe-hair0223--light-hThe first known modern humans in Europe (IE, not Neanderthals nor Homo Erectuses,) popularly known as Cro-Magnons and unpopularly known as European early modern humans, (because anthropologists hate being understood dislike sounding like commoners,) lived around 43,ooo-45,000 years ago in Italy. By 41,000 years ago, Cro-Magnons had reached the southern coast of England.

Humanity's path out of Africa

(Incidentally, Mungo Man, found in south-east Australia, is also estimated to be about 40,000 years old, suggesting that either:

A. People took a much longer route from Africa to Europe than to Australia
B. Europe was difficult to enter when folks left Africa, possibly because of glaciers or Neanderthals
C. There were multiple Out-of-Africa events, or
D. Our knowledge is incomplete.

D is obviously true, and I favor C regardless of Mungo’s true age.)

These Cro-Magnons appear to have been brown skinned, brown eyed, and black haired–they likely looked more like their close relatives in the Middle East (whatever they looked like,) than their distant descendants in modern Europe. (Despite all of the mixing and conquering of the centuries, I think modern Europeans are partially descended from Cro-Magnons, but I could be wrong.)

The Cro-Magnons carved the famous “Venus of Willendorf” (we don’t really know if the figurine was intended as a “goddess” or a fertility figure or just a portrait of a local lady or what, but it’s a nice name,) among many other similar figurines, some of them quite stylized.

Some people think the figurines look African, with cornrows or peppercorn hair and steatopygia. Others suggest the figurines are wearing hats or braids, and point out that not all of them are fat or have large butts.

 

 

So when did Europeans acquire their modern appearances? Here’s what I’ve found so far:

Wikipedia states:

Variations in the KITL gene have been positively associated with about 20% of melanin concentration differences between African and non-African populations. One of the alleles of the gene has an 80% occurrence rate in Eurasian populations.[52][53] The ASIP gene has a 75–80% variation rate among Eurasian populations compared to 20–25% in African populations.[54] Variations in the SLC24A5 gene account for 20–25% of the variation between dark and light skinned populations of Africa,[55]and appear to have arisen as recently as within the last 10,000 years.[56] The Ala111Thr or rs1426654 polymorphism in the coding region of the SLC24A5 gene reaches fixation in Europe, but is found across the globe, particularly among populations in Northern Africa, the Horn of Africa, West Asia, Central Asia and South Asia.[57][58][59]

maps-europelighteyesThe Guardian reports:

According to a team of researchers from Copenhagen University, a single mutation which arose as recently as 6-10,000 years ago was responsible for all the blue-eyed people alive on Earth today.

The team, whose research is published in the journal Human Genetics, identified a single mutation in a gene called OCA2, which arose by chance somewhere around the northwest coasts of the Black Sea in one single individual, about 8,000 years ago.

Haplogroups_europeWikipedia again:

The hair color gene MC1R has at least seven variants in Europe giving the continent a wide range of hair and eye shades. Based on recent genetic research carried out at three Japanese universities, the date of the genetic mutation that resulted in blond hair in Europe has been isolated to about 11,000 years ago during the last ice age.[25]

Recent archaeological and genetic study published in 2014 found that, seven “Scandinavian hunter-gatherers” found in 7700-year-old Motala archaeological site in southern Sweden had both light skin gene variants, SLC24A5 and SLC45A2, they also had a third gene, HERC2/OCA2, which causes blue eyes and also contribute to lighter skin and blond hair.[29]

Genetic research published in 2014, 2015 and 2016 found that Yamnaya Proto-Indo-Europeans, who migrated to Europe in early bronze age were overwhelmingly dark-eyed (brown), dark-haired and had a skin colour that was moderately light, though somewhat darker than that of the average modern European.[49] While light pigmentation traits had already existed in pre-Indo-European Europeans (both farmers and hunter-gatherers) and long-standing philological attempts to correlate them with the arrival of Indo-Europeans from the steppes were misguided.[50]

According to genetic studies, Yamnaya Proto-Indo-European migration to Europe lead to Corded Ware culture, where Yamnaya Proto-Indo-Europeans mixed with “Scandinavian hunter-gatherer” women who carried genetic alleles HERC2/OCA2, which causes combination of blue eyes and blond hair.[51][52][53] Descendants of this “Corded Ware admixture”, split from Corded Ware culture in every direction forming new branches of Indo-European tree, notably Proto-Greeks, Proto-Italio-Celtic, Proto-Indo-Iranians and Proto-Anatolians.[54] Proto-Indo-Iranians who split from Corded ware culture, formed Andronovo culture and are believed to have spread genetic alleles HERC2/OCA2 that causes blonde hair to parts of West Asia, Central Asia and South Asia.[52]

Genetic analysis in 2014 also found that Afanasevo culture which flourished in Altai Mountains were genetically identical to Yamnaya Proto-Indo-Europeans and that they did not carry genetic alleles for blonde hair or light eyes.[55][51][52] Afanasevo culture was later replaced by second wave of Indo-European invaders from Andronovo culture, who were product of Corded Ware admixture that took place in Europe, and carried genetic alleles that causes blond hair and light eyes.[55][51][52]

Dienekes writes:

An interesting finding [in Ancient human genomes suggest three ancestral populations for present-day Europeans] is that the Luxembourg hunter-gatherer probably had blue eyes (like a Mesolithic La Brana Iberian, a paper on which seems to be in the works) but darker skin than the LBK farmer who had brown eyes but lighter skin. Raghavan et al. did not find light pigmentation in Mal’ta (but that was a very old sample), so with the exception of light eyes that seem established for Western European hunter-gatherers (and may have been “darker” in European steppe populations, but “lighter” in Bronze Age South Siberians?), the origin of depigmentation of many recent Europeans remains a mystery.

Beleza et al, in The Timing of Pigmentation Lightening in Europeans, write:

… we estimate that the onset of the sweep shared by Europeans and East Asians at KITLG occurred approximately 30,000 years ago, after the out-of-Africa migration, whereas the selective sweeps for the European-specific alleles at TYRP1, SLC24A5, and SLC45A2 started much later, within the last 11,000–19,000 years, well after the first migrations of modern humans into Europe.

And finally from Wikipedia:

In a 2015 study based on 230 ancient DNA samples, researchers traced the origins of several genetic adaptations found in Europe.[46] The original mesolithic hunter-gatherers were dark skinned and blue eyed.[46] The HERC2 and OCA2 variations for blue eyes are derived from the original mesolithic hunter-gatherers, and the genes were not found in the Yamna people.[46] The HERC2 variation for blue eyes first appears around 13,000 to 14,000 years ago in Italy and the Caucasus.[38]

The migration of the neolithic farmers into Europe brought along several new adaptations.[46] The variation for light skin color was introduced to Europe by the neolithic farmers.[46] After the arrival of the neolithic farmers, a SLC22A4 mutation was selected for, a mutation which probably arose to deal with ergothioneine deficiency but increases the risk of ulcerative colitis, celiac disease, and irritable bowel disease.

The genetic variations for lactose persistence and greater height came with the Yamna people.[46]

To sum:

Skin: 10,000 years, 11-19,000 years, possibly arriving after blue eyes

Blond hair: 11,000 years

Blue eyes: 6-10,000 years ago, 13,000 to 14,000 years ago

It looks like some of these traits emerged in different populations and later combined as they spread, but they all look like they arose at approximately the same time.
Obviously I have neglected red and brown hair, green and hazel eyes, but the genetics all seem to be related.

Guest Post: Lawrence Glarus: Guest Families

idioma_hakka

Have you ever wondered if there are other market dominant minorities out there?  Blogger Lawrence Glarus has found another out there:

Most people in China are Han. In fact, the Han are 92% of the PRC. This would, in the popular imagination, imply that they culturally similar. This isn’t necessarily wrong but, like any nation, there are thinner slices you can make. Out of this mix of cultures has emerged another crab.  China has produced a market dominant minority diaspora: the Hakka. The Hakka are a subgroup of the Han. They have their own Chinese dialectic though their identity is mostly connected to patrilineal descent. What are the minimum steps to create a market dominant minority?
1. Migration
2. Economic niche formation by cultural bans or scarcity of normal work.
3. Limited integration.

In the Hakka we meet all the requirements. The Hakka originated from Northern China. This is not particularly exceptional since all Han originated from Northern China. Like many groups, there were multiple waves of migration from their homelands somewhere in the North. There seem to be a number of theories of their origin but there were plenty of wars and political events in which COULD have displaced them. Suffice to say something or someone gave them a reason to move.

“Migration and the stigma of rootlessness. Dominant Han tradition worshipped the native place, and the Min and Yue Cantonese disdain the Hakka as rootless. Four mass migrations shaped Hakka identity. In the first the Hakkas left Henan and Shandong during the chaos of the Jurchen attacks between the Tang and Song dynasties (907-959 A.D.), and settled around Changting (Tingzhou) in the underpopulated highlands of the Fujian-Jiangxi border. In the second they moved into north-eastern Guangdong during the period of the Song-Yuan dynastic transition (1127-1279), settling around Meixian and the North River highlands. In the third many Hakkas claimed untended land on the south-east Guangdong coast during the early Qing (1644-1800). Others, like Chen Yi’s kin, moved up to the Hunan-Jiangxi border. By 1800 Hakkas had also settled permanently in Guangxi, Hainan, Taiwan and famine-depopulated Sichuan.36 The fourth migration came in the mid-19th century, after nearly a million died in the Hakka-Bendi land wars, and in the aftermath of the Taiping Rebellion (1850-64). Hakkas dispersed further away from Guangdong, into Sichuan, Hong Kong and overseas.”-The Secret History of the Hakkas: The Chinese Revolution as a Hakka Enterprise Mary S. Erbaugh

That is a rough history, but then again China is/was a rough place.  It might actually may not be THAT exceptional.

“The name Hakka was first used by Guangfu Chinese. Hakka was originally used to refer to the third person and was gradually accepted as the ethnic name. Now, many people are proud to call themselves Hakka. The four Hakka states are Meizhou, Ganzhou, Huizhou, and Tingzhou. Meizhou is often referred to as the capital of the global population of Hakka because it has the highest population of Hakka, and many Hakka emigrated from Meizhou. Ganzhou is considered the ancestral home of Hakka, and is known as the “Hakka cradle”.
Hakka is one of the seven major Chinese dialects. Hakka dialects were formed as early as the Southern Song Dynasty through the inheritance of many language tones from the five dynasties and Song dynasties. The Hakka area is divided into “pure” and “impure” Hakka counties. There are 48 pure Hakka counties and cities in regions bordering Guangdong, Fujian, and Jiangxi. Although the total population of Hakka has not been determined, it is estimated that there are about 50 million Hakka worldwide. Although the Hakka population is an important component of Han populations, the anthropologic characteristics of Hakka have not been reported.” -Physical characteristics of Chinese Hakka ZHENG

Hakka roughly translates to “Guest Families”, which in my opinion is a perfect name for a market dominant minority. A guest family is welcome, but they never really integrate. Even after at least 1000 years of living in South China the Hakka are still distinct (or at least have a distinct identity) from the other Northern Chinese peoples who got there first.  The Hakka, for example, typically didn’t bind their daughter’s feet.

The word “Hakka” is as blatant a brand of impoverished wandering as “Gypsy” or “Okie.” It was originally a hostile outside coinage, the Cantonese pronunciation of the characters for “guest family,” “settlers” (Mandarin pronunciation is kejia). “Guest” is often pejorative in Chinese. Jia is used in derisive names for minorities, but not for other Han except the even more benighted Danjia (Tanga, Tanka) boat people..Longsettled Han call themselves “locals,” “natives” bendi (punti), literally “rooted in the soil.” -The Secret History of the Hakkas: The Chinese Revolution as a Hakka Enterprise Mary S. Erbaugh

It is funny for Westerners to see this sort of behavior and attitudes in foreign nations.  Unlike our history, the dirty laundry of foreign (non-Western) cultures tends to not be aired.  There is nothing wrong with a little parochialism.  It is still a little hard to imagine a group being “guests” for a thousand years.  How many American’s even know the word “Okie” anymore?  To be fair it’s still fresh in the memories of the people of Oklahoma.

Hakkas are also called “newcomers” (xin ren) or “arrivals” (lai reri). They are often called “Cantonese,” especially in Taiwan, Hunan and Sichuan. Hakka dialect is also called “dirt Cantonese” (tu Guangdonghua); “newcomer talk” (xin min hua); or “rough border talk” (ma jie hua) (see Cui Rongchang, “Sichuan fangyan de biandiao xianxiang” -The Secret History of the Hakkas: The Chinese Revolution as a Hakka Enterprise Mary S. Erbaugh

It is certainly interesting that these people who focused on education would have a language called “rough border talk”.  It is probable that any successful Hakka would learn and speak Madarin (or whatever was the court dialect de jour) well though.  All the famous (at least famous outside China) Hakka we know of spoke other languages very well and did not seemingly utilize Hakka language in their public persona.  In fact, the Hakka seem to do much better in other people’s areas than in their own, where they have tended to be poor farmers.

“As Hakkas tend to be very clannish, strangers who found out that the other party is a Hakka will affectionately acknowledge each other as “zi-jia-ren” (自家人) meaning “all’s in the same (Hakka) family”.” -La Wik

China was very clannish up until the Communists took over. The Communists naturally wanted to break up the clan structures which were a threat to their power. In the modern day as the PRC has relaxed their grip Clans are re-emerging as power centers in China. The fact that the Hakka are clannish shouldn’t surprise us, but it should be noted that they see each other as a larger clan 50 million rather than the typical 50-500 of a regularly organized clan.

When the Hakka found themselves in an already populated area in South China they had only marginal land to work with. Rather than displacing the natives they found themselves adopting economically niche strategies.

“Hakka culture have been largely shaped by the new environment which they had to alter many aspects their culture to adapt, which helped influence their architecture and cuisine. When the Hakka expanded into areas with pre-existing populations in the South, there was often little agricultural land left for them to farm. As a result, many Hakka men turned towards careers in the military or in public service. Consequently, the Hakka culturally emphasized education.” -La Wik

snail_pit_tulou

This tradition seemingly continues till today. Given the history of China, there would have been plenty of opportunities to pursue education, military or public service.  While the Hakka are quite interesting in their own country they are even more interesting in other countries. Having a long tradition of military and publics service has made them prominent and influential in the diaspora.

“There is a Chinese saying, “有阳光的地方就有华人, 有华人的地方就有客家人”, which literally means “Wherever there is sunshine, there will be Chinese. Wherever there is Chinese, there will be Hakka.””-La Wik

lky-pm-lee-family-data

So if the Hakka focussed on education, military and civil service how good could they be at it?  Could there be a genetic or cultural propensity to enter the civil service that can overcome cultural barriers between cultures? Here is a short list of prominent Hakka that you may know of:

  1. Sun Yat-sen
  2. Lee Kuan Yew
  3. Deng Xiaoping

Okay, so that list wasn’t that long let’s get a list of Presidents of foreign countries who were Hakka. Years listed are years in power.

No Western country has had a Hakka Prime Minister or President but they do have a few Hakka politicians. Here are few. Firsts are noted.

It seems like wherever the Chinese go the Hakka are soon to find themselves in a position of power.  The Hakka have been very successful in this niche.  So we know that other market dominant minorities have a tendency to be not far behind a revolution, is that also true of the Hakka?

“The Hakkas have had a significant influence, disproportionate to their smaller total numbers, on the course of modern Chinese and overseas Chinese history, particularly as a source of revolutionary, political and military leaders.” -La Wik

Hong Xiuquan 1812-1864 Leader, Taiping Rebellion Meixian, Guangdong
Zheng Shiliang 1863-1901  Huizhou Uprising Huiyang, Guangdong

Hsieh Liang-mu 1884-1931 Huanghuagang Uprising Meixian, Guangdong
Zeng Sheng 1910-1995 Column guerilla force, Hong Kong Huiyang, Guangdong

Check out this page on Wikipedia.  I listed revolutionary leaders but if you take a look at the page there are quite a number of plain members, military leader, and politicians coming out of the Hakka.  They are especially prevalent in the Communist Party of China and the Taiping Rebellion.  Keep in mind the size of the Hakka relative to the size of China.  Nowadays at best their total population including diaspora is 4% of the population of China.

“The Paradox of Hakka Obscurity and High Political Position The Hakka are an impoverished and stigmatized subgroup of Han Chinese whose settlements are scattered from Jiangxi to Sichuan. Socialist revolution meshed well with the Hakka tradition of militant dissent, so that their 3 per cent of the mainland population has been three times more likely than other Han to hold high position. Six of the nine Soviet guerrilla bases were in Hakka territory, while the route of the Long March moved from Hakka village to Hakka village. (Compare Maps 1, 2, 3 and 4.)1 In 1984, half the Standing Committee of the Politburo were Hakka, and the People’s Republic and Singapore both had Hakka leaders, Deng Xiaoping and Lee Kwan Yew, joined by Taiwan’s President Lee Teng-Hui in 1988.” -The Secret History of the Hakkas: The Chinese Revolution as a Hakka Enterprise Mary S. Erbaugh

There seems to be a cultural/phenotypic niche for the market dominant minority.  The Hakka are an interesting case study in how completely different genetic populations can produce similar political/cultural results.  Obviously, the Hakka are not identical to other diasporas, but the parallels are worth a thorough investigation.

If you liked Lawrence’s post, take a moment to enjoy his work on Degenerate Trucks (complex adaptive systems) or his Notes on the neural systems of sponges. If you’re looking for your regular dose of EvX, then you should also check out Lawrence’s blog, where I’m the guest.

Weight, Taste, and Politics: A Theory of Republican Over-Indulgence

So I was thinking about taste (flavor) and disgust (emotion.)

As I mentioned about a month ago, 25% of people are “supertasters,” that is, better at tasting than the other 75% of people. Supertasters experience flavors more intensely than ordinary tasters, resulting in a preference for “bland” food (food with too much flavor is “overwhelming” to them.) They also have a more difficult time getting used to new foods.

One of my work acquaintances of many years –we’ll call her Echo–is obese, constantly on a diet, and constantly eats sweets. She knows she should eat vegetables and tries to do so, but finds them bitter and unpleasant, and so the general outcome is as you expect: she doesn’t eat them.

Since I find most vegetables quite tasty, I find this attitude very strange–but I am willing to admit that I may be the one with unusual attitudes toward food.

Echo is also quite conservative.

This got me thinking about vegetarians vs. people who think vegetarians are crazy. Why (aside from novelty of the idea) should vegetarians be liberals? Why aren’t vegetarians just people who happen to really like vegetables?

What if there were something in preference for vegetables themselves that correlated with political ideology?

Certainly we can theorize that “supertaster” => “vegetables taste bitter” => “dislike of vegetables” => “thinks vegetarians are crazy.” (Some supertasters might think meat tastes bad, but anecdotal evidence doesn’t support this; see also Wikipedia, where supertasting is clearly associated with responses to plants:

Any evolutionary advantage to supertasting is unclear. In some environments, heightened taste response, particularly to bitterness, would represent an important advantage in avoiding potentially toxic plant alkaloids. In other environments, increased response to bitterness may have limited the range of palatable foods. …

Although individual food preference for supertasters cannot be typified, documented examples for either lessened preference or consumption include:

Mushrooms? Echo was just complaining about mushrooms.

Let’s talk about disgust. Disgust is an important reaction to things that might infect or poison you, triggering reactions from scrunching up your face to vomiting (ie, expelling the poison.) We process disgust in our amygdalas, and some people appear to have bigger or smaller amygdalas than others, with the result that the folks with more amygdalas feel more disgust.

Humans also route a variety of social situations through their amygdalas, resulting in the feeling of “disgust” in response to things that are not rotten food, like other people’s sexual behaviors, criminals, or particularly unattractive people. People with larger amygdalas also tend to find more human behaviors disgusting, and this disgust correlates with social conservatism.

To what extent are “taste” and “disgust” independent of each other? I don’t know; perhaps they are intimately linked into a single feedback system, where disgust and taste sensitivity cause each other, or perhaps they are relatively independent, so that a few unlucky people are both super-sensitive to taste and easily disgusted.

People who find other people’s behavior disgusting and off-putting may also be people who find flavors overwhelming, prefer bland or sweet foods over bitter ones, think vegetables are icky, vegetarians are crazy, and struggle to stay on diets.

What’s that, you say, I’ve just constructed a just-so story?

Well, this is the part where I go looking for evidence. It turns out that obesity and political orientation do correlate:

Michael Shin and William McCarthy, researchers from UCLA, have found an association between counties with higher levels of support for the 2012 Republican presidential candidate and higher levels of obesity in those counties.

Shin and McCarthy's map of obesity vs. political orientation
Shin and McCarthy’s map of obesity vs. political orientation

Looks like the Mormons and Southern blacks are outliers.

(I don’t really like maps like this for displaying data; I would much prefer a simple graph showing orientation on one axis and obesity on the other, with each county as a datapoint.)

(Unsurprisingly, the first 49 hits I got when searching for correlations between political orientation and obesity were almost all about what other people think of fat people, not what fat people think. This is probably because researchers tend to be skinny people who want to fight “fat phobia” but aren’t actually interested in the opinions of fat people.)

The 15 most caffeinated cities, from I love Coffee
The 15 most caffeinated cities, from I love Coffee–note that Phoenix is #7, not #1.

Disgust also correlates with political belief, but we already knew that.

A not entirely scientific survey also indicates that liberals seem to like vegetables better than conservatives:

  • Liberals are 28 percent more likely than conservatives to eat fresh fruit daily, and 17 percent more likely to eat toast or a bagel in the morning, while conservatives are 20 percent more likely to skip breakfast.
  • Ten percent of liberals surveyed indicated they are vegetarians, compared with 3 percent of conservatives.
  • Liberals are 28 percent more likely than conservatives to enjoy beer, with 60 percent of liberals indicating they like beer.

(See above where Wikipedia noted that supertasters dislike beer.) I will also note that coffee, which supertasters tend to dislike because it is too bitter, is very popular in the ultra-liberal cities of Portland and Seattle, whereas heavily sweetened iced tea is practically the official beverage of the South.

The only remaining question is if supertasters are conservative. That may take some research.

Update: I have not found, to my disappointment, a simple study that just looks at correlation between ideology and supertasting (or nontasting.) However, I have found a couple of useful items.

In Verbal priming and taste sensitivity make moral transgressions gross, Herz writes:

Standard tests of disgust sensitivity, a questionnaire developed for this research assessing different types of moral transgressions (nonvisceral, implied-visceral, visceral) with the terms “angry” and “grossed-out,” and a taste sensitivity test of 6-n-propylthiouracil (PROP) were administered to 102 participants. [PROP is commonly used to test for “supertasters.”] Results confirmed past findings that the more sensitive to PROP a participant was the more disgusted they were by visceral, but not moral, disgust elicitors. Importantly, the findings newly revealed that taste sensitivity had no bearing on evaluations of moral transgressions, regardless of their visceral nature, when “angry” was the emotion primed. However, when “grossed-out” was primed for evaluating moral violations, the more intense PROP tasted to a participant the more “grossed-out” they were by all transgressions. Women were generally more disgust sensitive and morally condemning than men, … The present findings support the proposition that moral and visceral disgust do not share a common oral origin, but show that linguistic priming can transform a moral transgression into a viscerally repulsive event and that susceptibility to this priming varies as a function of an individual’s sensitivity to the origins of visceral disgust—bitter taste. [bold mine.]

In other words, supertasters are more easily disgusted, and with verbal priming will transfer that disgust to moral transgressions. (And easily disgusted people tend to be conservatives.)

The Effect of Calorie Information on Consumers’ Food Choice: Sources of Observed Gender Heterogeneity, by Heiman and Lowengart, states:

While previous studies found that inherited taste-blindness to bitter compounds such
as PROP may be a risk factor for obesity, this literature has been hotly disputed
(Keller et al. 2010).

(Always remember, of course, that a great many social-science studies ultimately do not replicate.)

I’ll let you know if I find anything else.

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

Today we are finishing 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.

Eastern chimpanzee female twins 'Golden & Glitter' aged 14 years with their babies 'Gosama' aged 3 months and 'Glama' aged 1 year (Pan troglodytes schweinfurtheii). Gombe National Park, Tanzania. September 2012.
Eastern chimpanzee female twins ‘Golden & Glitter’ aged 14 years with their babies ‘Gosama’ aged 3 months and ‘Glama’ aged 1 year, from Jane’s Blog.

Melissa has a baby:

“As Melissa came down the slope toward our camp she moved on three limbs, supporting the newborn with one hand. Every so often she stopped and seemed to disentangle something from the undergrowth. When she got closer we saw that this was the placenta, still attached to the baby by the umbilical cord. …

“She seemed dazed, her eyes not quite focused, her movements slow and uncertain. When one of the mature males arrived, Melissa, usually so quick to greet another chimp, so anxious to ingratiate herself with her superiors, ignored him completely. … She continued to sit, the baby cuddled between her thighs, her feet crossed under his tiny rump, her arm behind his head. …. The baby’s head fell back on her knees, and Melissa, looking down, stared long at the tiny face.”

Fifi’s fascination with her little brother, Flint:

“Flo sat down and began to tickle Flint’s neck with small nibbling movements of her worn teeth, and Fifi once again sat close and reached out to make a few grooming movements on Flint’s back. Flo ignored this. Earlier, though, when Flint was not yet two months old, Flo had usually pushed Fifi’s hand away each time she had tried to touch Flint…

“When Flint was three months old… he began to respond when Fifi approached by reaching out to her. Fifi became more and more preoccupied with him. She began to make repeated attempts to pull him away from his mother. …

“When Flint was thirteen weeks old we saw Fifi succeed in pulling him away from his mother. Flo was grooming Figan when Fifi, with infinite caution and many quick glances toward her mother’s face, began to pull at Flint’s foot. Inch by inch she drew the infant toward her–and all at once he was in her arms. Fifi lay on her back and cuddled Flint to her tummy with her arms and legs. She lay very still. …

Flo the chimpanzee, image from Jane Goodall's website
Flo the chimpanzee, image from Jane Goodall’s website

“Flo for the first few moments appeared to take no notice at all. But when Flint, who had possibly never lost contact with his mother’s body, reached around and held his arms toward her, pouting his lips and uttering a soft hoo of distress, Flo instantly gathered him to her breast and bent to kiss his head with her lips. …

“After this, not a day passed without Fifi pulling her infant brother away from Flo. …

“When Flint was very small his two elder brothers, although they sometimes stared at him, paid him little attention.”

Pom and Passion:

“Babies less than five months of age are normally protected by their mothers from all contact with other chimpanzees, except their own siblings. … It was, however, very different for Pom, one of the first female infants born into our group. Her mother, Passion, actually laid the baby on the ground the very first day of her life and allowed two young females to touch and even groom her as she lay there. But then, in all respects, Passion was a somewhat unnatural mother.

“She was no youngster, this Passion… I know she lost one infant before Pom’s birth in 1965. If her treatment of Pom was anything to go by, I suspect Passion had lost other infant, too, for Pom had to fight for her survival right from the start. When she was a mere two months old, she began to ride on her mother’s back–three or four months earlier than other infants. It started when Pom hurt her foot badly. She could not grip properly, and Passion, rather than constantly support her infant with one hand as most mothers wold have done, probably pushed Pom up onto her back. The very first day that Pom adopted this new riding position, Passion hurried for about thirty yards in order to greet a group of adult males, seeming quite without concern for her infant, Pom, clinging frantically, managed to stay aboard–though much older infants, when they tart riding on their mothers’ back, usually slide down if their mothers make sudden movements. …

“Flo, it will be remembered, was very solicitous when Flint was finding his feet, gathering him up if he fell and often supporting him with one hand as he wobbled along. …. Passion was positively callous. One day, precious to which Pom had never been seen to totter on her own more than a two yards, Passion suddenly got up and walked away from her infant. Pom, struggling to follow and falling continually, whimpered louder each time, and finally her mother returned and shoved the infant onto her back. This happened repeatedly. As Pom learned to walk better, Passion did not even bother to return when the infant cried–she just waited for her to catch up by herself.

“… It was not really surprising that, during her second year, when most infants wander about happily quite far away from their mothers, Pom usually sat or played very close to Passion. For months on end she actually held tightly on to Passion with one hand during her games with Flint and Goblin and the other infants. Obviously she was terrified of being left behind.

EvX: Passion, aside from being a terrible mother, was a cannibal. According to Wikipedia:

She, along with her daughter Pom, captured, killed, and ate several newborns at Gombe.[78]

Passion only had three children who made it to adulthood. Of these, two had no surviving children–Pom had one child who died, and then Pom disappeared; Pax lost his testicles in a conflict between other chimps and his mother, and never reproduced. The Wikipedia doesn’t record whether the third child had any children, but compared to Flo, Wilkie, and even Frodo, Passion was clearly not successful. (Though her cannibalism may have ultimately benefited other, more distantly related chimps in her family.)

Childhood:
“Like Human children, chimpanzee children are dependent on their mothers for several years. …

“Just then Flint, six months older than Goblin, came bouncing up and the two children began to play, both showing their lower teeth in the chimpanzee’s playful smile. Flo was reclining nearby grooming Figan; Goblin’s mother, Melissa, was a little farther away, also grooming. It was so peaceful…. All at once a series of pant-hoots announced the arrival of more chimpanzees, and there was instant commotion in the group. Flint pulled away from the game and hurried to jump onto Flo’s back as she moved for safety halfway up a palm tree. I saw Mike with his hair on end beginning to hoot; I knew he was about to display. So did the other chimpanzees of his group–all were alert, prepared to dash out of the way or to join in the displaying. All, that is, save Goblin. He seemed totally unconcerned and, incredibly, began to totter toward Mike. Melissa, squeaking with fear, was hurrying toward her son, but she was too late. Mike began his charge, and as he passed Goblin seized him up as though he were a branch and dragged him along the ground.

“An then the normally fearful, cautious Melissa, frantic for her child, hurled herself at Mike. It was unprecedented behavior, and she got severely beaten up for her interference, but she did succeed in rescuing Goblin–the infant lay, pressed close to the ground and screaming, where the dominant male had dropped him. Even before Mike had ceased his attack on Melissa the old male Huxley had seized Goblin from the ground. I felt sure he too was going to display with the infant, but he remained quite still, holding the child and staring down at him almost, it seemed in bewilderment. Then as Melissa, screaming and bleeding, escaped from Mike, Huxley set the infant on the ground. As his mother hurried up to him Goblin leaped into her arms…

“Normally, small infants are shown almost unlimited tolerance from all other members of the community; it almost seem as though the adult male may lose many of his social inhibitions during his charging display.”

EvX: At another time, when Goblin got lost in some confusion, Mike rescued him and stayed with him until Melissa returned–Mike wasn’t normally aggressive toward the small children in his troop.

Teenagers:

“Although I never saw a juvenile son who was frightened of his mother, as Miff [female] was of Marina, nevertheless the male juvenile normally shows a good deal of respect for his mother.
One day I came across Figan with the freshly killed body of a colobus monkey. He climbed a tree with the tail of the monkey in one hand and the body slung over his shoulder He was closely pursued by Fifi. When he reached a comfortable branch he sat and began eating, and Fifi, who was about three years old at the time, begged persistently. Several times Figan gave he small fragments of meat.
A few minutes later I saw Flo climbing toward Figan. Instantly he slung the carcass over his shoulder and climbed to a higher branch. Flo remained in a low fork, gazing around, not once looking at her son. He relaxed and began feeding again, though constantly he glanced somewhat apprehensively toward his mother. The old female sat there for a full ten minutes. Then, with only a preliminary fleeting glance at Figan, she very slowly climbed slightly higher, looking oh so nonchalant, and sat on the net branch up. …

“When he reached a very high position in the tree Flo could keep up her pretence no longer–without warning she rushed toward him. Figan with a scream leaped down into the foliage and vanished from sight…

“For the most part, these adolescent males, even when they were ten or eleven years old, continued to how respect for their old mothers. If we offered a banana the son usually stood back and waited for his mother to take the fruit. …

“On many occasions a mother will hurry to try to help her adolescent son. Once when Mr. Worzle attacked Faben, who was then about twelve, Flo, with hair on end and Flint clinging to her, rushed toward the scene of strife. As she approached, Faben’s frightened screams turned instantly to angry waa barks and he began to display, standing upright and swaggering from foot to foot. Then mother and son, side by side, charged along the track toward old Mr. Worzle… Mr. Worzle turned and fled. …

“As the adolescent male grows older, he is increasingly likely to hurry to his mother’s aid when she is threatened. …

“In his dealings with the higher-ranking males the adolescent must be cautions, because now, more than when he was a mere juvenile, an act of insubordination tends to bring severe retribution. …”

EvX: Jane notes that the chimps show sign of trying to avoid incest, though they likely have no way of avoiding father/daughter couplings, half-sibling couplings, and similar such cases.

Pestilence rides a white horse:

“Olly’s new baby was four weeks old when he suddenly became ill. … One morning Olly walked slowly into camp supporting him with one hand. Each time she made a sudden moved, he uttered a loud squawk as though in pain, and he was gripping badly. First one hand or foot and then another slipped from Olly’s hair and dangled down. …

“Next morning it was obvious that the baby was very ill. All his four limbs hung limply down and he screamed almost every time his mother took a step. … Olly only moved a few yards at a time, and then, as though worried by the screams of her infant, sat down to cradle him close. When he quieted, she moved again, but he instantly began to call out so that once more she sat to comfort him. After traveling about a hundred yards, which took her just over half an hour, Olly climbed into a tree. Again she carefully arranged her baby’s limp arms and legs on her lap as she sat down. … The baby stopped screaming and, apart from occasionally grooming his head briefly, Olly paid him no further attention.

“When we had been there some fifteen minutes it began to pour, a blinding deluge that almost obscured the chimps from my sight. During the storm, which went on for thirty minutes, the baby must either have died or lost consciousness…

“Olly climbed down the tree with her infant carelessly in one hand, and when she reached the ground she flung the limp body over her shoulder. It was as though she knew he was dead….

“The following day Olly arrived in camp, followed by Gilka, with the corpse of her infant slung over her shoulder. When she sat down the body sometimes dropped heavily to the ground. Occasionally Olly pushed it into her groin as she sat; when she stood she held it by an arm or even a leg. …

“Finally Olly wandered away from camp and she and Gilka, with me following went some way up the opposite mountain slope. Olly seemed dazed; she looked neither left nor right but plodded up the narrow trail through the forest., the body slung over her neck, until she reached a place halfway up the mountainside. Then she sat down.

“The dead infant slumped to the ground beside her, and other than to glance down briefly, Olly ignored it. She just sat staring into space…

“Now, at last, came Gilka’s opportunity to play with her sibling… Carefully she groomed it, and then she even tried to play, pulling one dead hand into the ticklish spot between her collarbone and neck… We had been so glad for Gilka’s sake when old Olly had given birth again–but it looked as if Gilka was always to be ill-fated. … Only then did Olly’s lethargy leave her for a moment. She snatched the body away, and then once more let it fall to the ground. …

“The following afternoon Olly and Gilka arrived in camp without the body. …

“Had we known at the time that Olly’s infant was without doubt the first victim of the terrible paralytic disease that struck our chimpanzee community, I wouldn’t have have followed the family–for at this time my own baby was on the way …

“When we realized that the disease was probably polio, we panicked, for Hugo and I and our research assistant Alice Ford had not received a full course of polio vaccine. … The Pfizer Laboratories in Naiobi generously supplied us with the oral vaccine, and we offered it to the chimps in bananas. …

“I think those few moths were the darkest I have ever lived through: every time a chimp stopped visiting the feeding area, we started to wonder whether we would ever see him again, or worse, if he would reappear hideously crippled. Fifteen chimpanzees in our group were afflicted, of whom six lost their lives… Gilka lost partial use of one hand and Melsa was affected in her neck and shoulders. … Pepe and Faben both appeared after short absences trailing one useless arm. One adolescent male returned, after a long absence, shuffling along in a squatting position and with both arms paralyzed. He could only eat the bits and pieces he was able to reach with his lips, and he was nothing but a skeleton covered with dull, staring hair. We had to shoot him. And thew ere other victims–like fat, bustling J.B., of whom we had all become so fond–who just disappeared, and we could only conjecture about their lonely deaths.

EvX: Old Mr. McGregor also died, the account of which is the saddest part of the book.

“We did not allow any of the chimps to see his dead body, and for a long time it looked as if Humphrey did not realize he would not meet his old friend again. For six months he kept returning to the place where Gregor had spent the last days of his life and would sit on one tree or another staring around, waiting, listening. During this time he seldom joined the other chimps when they left together for a distant valley; he sometimes went a short way with such a group, but within a few hours he usually came back again and sat staring over the valley, waiting, surely to see old Gregor again, listening for the deep, almost braying voice, so similar to his own, that was silenced forever.”

Let us conclude on a more upbeat note (I think I will just skip who killed whom in the Gombe war; you can look it up yourself if you want to know):

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 near [David Greybeard] at the bank of a tiny trickle of crystal-clear water, I saw a ripe red palm nut lying on the ground. I picked it up and held it out to him on my open palm. He turned his head away. When I moved my hand closer he looked at it, then at me, and then he took the fruit, and at the same time held my hand firmly and gently with his own. As I sat motionless he released my hand, looked down at the nut, and dropped it to the ground.

“At that moment there was no need of any scientific knowledge to understand his communication of reassurance. … It was a reward far beyond my greatest hopes.”

I’m Bloody Tired of the Classism Inherent in the Election

Is the darn thing over yet?

No?

Damn.

American politics are deeply, fundamentally classist.

Those who want to sound high-class (or are) adopt the rhetoric of the liberals. The working class go Republican.

You know what? Screw it, I don’t even want to pull up data on this. If you don’t believe me, go stick your head back in the sand and believe whatever you want. Tell yourself that you despise conservatives because they are Bad People and not because they are Low Class and not Good People Like You. And conservatives can tell themselves that they hate liberals because liberals are Bad People who Hate Americans.

In reality, of course, most people are good people (except for the one who work in HR, who should all be shot–NAHRALT, of course.)

When people hear that I write about “politics” they tend to assume that this means that I enjoy reading/debating about electoral politics. The truth is that I basically hate electoral politics.

Most of what passes for “political debate” is really just tribal signalling. Tribal signaling need not be wise, thoughtful, or factually correct; it need only signal “my tribe is better than your tribe.” I might be able to stand this kind of inanity if I felt comfortably a member of one of the big tribes and basically hated (or had no friends in) the other tribe. Of course, I have to have friends from across the economic system.

Working class and prole whites are convinced that elite whites hate them. Elite whites are convinced that prole whites hate just about everyone. And blacks, Muslims, etc., are probably pretty concerned about proles hating them, too. Family members are voting for the people they think are on their side against those bad people on the other side. Friends are voting for different people whom they think are on their side against those bad people on the other side.

Almost no one I’ve talked to is voting for a particular side because they’ve undertaken a careful study of the particular issues under discussion and decided that one of the candidates has the best policies. How many Democratic voters agree with Hillary’s stance on the Iraq War? How many Republicans agree with Trump’s opinion on the same?

The most vocal Trump supporter I know was talking about how we need to do more for immigrant children coming from Latin America just last year, and has told me that they don’t actually want to see anyone deported. They just hate liberals, and they are voting for Trump to stick it to the liberals.

No matter how I vote, someone gets fucked.

The West has no Idea how to Handle Islam

ETA: more terrorist attacks have happened since I wrote this. I give up on covering them all.

Most of the world’s ethnic groups divide up pretty neatly–if not into countries, then into distinct groups spread across several different countries. Alliances between countries are normally formally announced, so that you know that if you attack, Japan circa 1942, you’re likely to be counter-attacked by Germany. You don’t have to worry, though, about being attacked by China, or random Chinese people living in your own country, because China isn’t Japan, doesn’t have an alliance with Japan, and the Chinese people don’t particularly care what you do to Japan so long as you don’t do it to them. (In fact, the Chinese were pretty pissed at Japan by that point.)

As long as two countries don’t have an alliance, you can normally attack one without worrying about the other.

Islamic identity seems to function somewhat differently (at least in some cases.)

Americans are used to thinking of religion as a set of beliefs, eg, “God made the world in 6 days,” or “Enlightened people move on to a higher plane of existence,” or “You shouldn’t turn on the lights on Saturday.” Religion therefore falls under our philosophical notion of freedom of conscience, enshrined in the First Amendment.

But throughout much of the world, religion functions much more like ethnicity than like belief. Yes, technically people from different religions believe different things, but as a practical matter, the belief that “We are people who follow the true religion and they are people who follow the false religion,” is more important than the specific details of the religions involved.

If you don’t believe me, just ask yourself what were the theological underpinnings of the conflict between Catholics and Protestants in Northern Ireland?

It’s a near meaningless question. Knowing that the Catholics have a Pope and the Protestants don’t because centuries ago because King Henry VIII wanted a divorce tells you nothing useful. You just need to know that Catholics and Protestants see themselves as different groups.

Judaism is the only religion Westerners have much experience with and are used to thinking of as operating like an ethnic group. Most Westerners I’ve discussed the subject with seem vaguely confused about what exactly Judaism is, but they understand pretty well that if you start massacring Jews in your country, you should expect a visit from the Israeli air force.

But Jews are a relatively small group, with only one official country which has clearly articulated alliances with others, so there is not too much confusion on the point.

Recent random terrorist attacks in the West have included a Pakistani couple who opened fire at a Christmas party in an Bernardino, CA; a Moroccan Tunisian man who drove a truck into a crowd of French folks celebrating Bastile Day; and an Afghan teenager who attacked a train full of Germans with an axe.

The US is not at war with Pakistan*, France with Morocco, nor Germany with Afghanistan. Random American, French, and German citizens abroad do not, to my knowledge, make politically motivated mass-attacks on their host countries.

*Or is the US? I know Obama has authorized drone strikes on targets within Pakistan, among other countries. It was easy under Bush II to keep track of America’s military engagements, because they were big, declared, and obvious. Under Obama, we are not exactly at war with Pakistan, but we do sometimes kill people who happen to be living in Pakistan, like Osama Bin Laden. It’s confusing.

At any rate, according to Wikipedia, the Farooks were motivated by the desire to be jihadis and allegiance to ISIL, not Pakistan. Riaz Ahmadzai, the 17 year old Afghan, also appears to have acted on behalf of ISIL (though probably not on ISIL’s instruction,) not Afghanistan’s. Mohamed Lahouaiej-Bouhlel, the Tunisian armed with a 19-ton truck, also committed his attack on behalf of ISIL, not Tunisia. Fun fact: “A UN report from May 2015 shows that 25,000 “foreign terrorist fighters” from 100 countries have joined “Islamist” groups, many of them working for ISIL or al-Qaeda.[393]

Picture 4

The US, France, Germany, Russia, India, and probably the majority of the world are, in fact, at war with ISIL, which makes it kind of incredible that it still exists–the rest of the world has forgotten how to conduct wars.

You might think that ISIL draws its supporters from the ranks of the super-devout, but the opposite is most likely true:

“I always thought the people most likely to join a terrorist group were the people praying five times a day with a beard and being very pious and going to a radical mosque,” says Usmani, who is Muslim and was born in Pakistan. He came to the U.S. to do his PhD at Florida Institute of Technology.

But what he found is that they are more likely to go from secular to radicalized. They are often educated online — among the 5,000+ YouTube videos from supposed Muslim “scholars.” Technology has enabled an explosion of content that is far from true Islam.*

Now, this is a rotten pickle. It’s bad enough to worry about about Japanese-Americans when you are at war with Japan; it’s another thing entirely to have to worry about anyone whose parents were vaguely Buddhist.

I am particularly saddened by all of this for personal reasons. This isn’t the world I asked for; I certainly don’t want this conflict.

I assume the solution is to actually defeat ISIL instead of pussy-footing around so that it stops being a problem. But look how well that went the last time we tried to take over a country in the Middle East and replace its government with a more favorable regime.

 

*Phrases like “true Islam” annoy me because as far as I know, there is no Islamic “Pope” who gets to decide what is and isn’t “true Islam.” Nevertheless, it remains a constant in my experience that really devout people (of whatever religion) tend to believe more in principles like “love everyone because we are all God’s children,” than moderate religious folks.
