Despite San Jose’s reputation for inclusivity (about 40 percent of residents are foreign born) and economic mobility (ranked best among U.S. cities), Mayor Sam Liccardo says the region’s affordable housing shortage has forced thousands to crash on couches, live in their cars, or stay on the streets.
Here, I think I see your problem:
Despite Because of San Jose’s reputation for inclusivity (about 40 percent of residents are foreign born) and economic mobility (ranked best among U.S. cities), Mayor Sam Liccardo says the region’s affordable housing shortage has forced thousands to crash on couches, live in their cars, or stay on the streets.
There. Fixed it for you.
On the other hand, these startups might be nice places to live.
The authors use the vital statistics of 320,247 Maine citizens over a 29-year period to show that those born in 3-year peaks of 11-year solar cycles live an average of 1.5 years (CL 1.3–1.7) less than those born in non-peak years. Males are more sensitive than females to this phenomenon, which is statistically demonstrable well into adult life, showing the effect of probable UVR on the early human embryo despite superimposed adult lifetime hazards.
… we studied social mobility in five cohorts from three countries. We found that people with more education-linked genetics were more successful compared with parents and siblings. We also found mothers’ education-linked genetics predicted their children’s attainment over and above the children’s own genetics, indicating an environmentally mediated genetic effect. Findings reject pure social-transmission explanations of education GWAS discoveries. Instead, genetics influences attainment directly through social mobility and indirectly through family environments.
White Woman: Your parents would be embarrassed by you–and your grandparents–who have been oppressed by white men throughout history. You should be ashamed of yourself.
Asian Man: Why?
White Woman: Because you’re an Asian giving in to white supremacy, motherfucker
I don’t know anything about Andy Ngo, the photographer who captured this segment and wrote the thread, but I do think there’s some seriously non-self-aware irony in a white person insulting and verbally abusing an Asian person for a perceived failure to feel oppressed by other white people. If she’s so concerned about whites oppressing Asians, maybe she should… stop doing it herself?
As the crowd made their way to a nearby courthouse, they marched in the middle of the street, bringing traffic to a stop though they didn’t have a permit. Kent Houser, 74, made the mistake of attempting to pass them in his sedan. His car slowly pushed against a masked marcher. The crowd surrounded the car and started kicking it. After speeding down the block, Mr. Houser stepped out and was assaulted by the mob. They pushed him and smashed his car with clubs after he managed to get back inside the vehicle. No police were in sight even though the central precinct was blocks away. …
The mob later occupied a busy intersection. When a middle-aged man driving a car with North Carolina plates stopped in confusion, the agitators descended on him. “You white little f—er!” shouted one white man. “You are a little white supremacist. Go back to North Carolina where you came from.” The driver phoned police for assistance. Nobody came. …
A block away, police officers looked on passively. Why didn’t they respond? The department told me in a statement that it feared intervention would “change the demeanor of the crowd for the worse.”
Such lawlessness is increasingly typical here. Portland’s Resistance organized a protest after Election Day 2016 that turned into a riot. Masked vandals smashed stores and set fires, causing over $1 million in damage.
I remember those riots. They put a friend of mine who ticks every SJ-interest box you can name in danger, because antifa do not actually care about the people they claim to care about.
I’m sure the Portland Police would like to do their jobs, but it’s not worth it–either they’ve been told not to by their superiors or they’re guaranteed to get sued if they do.
Scientists have long believed that the “great leap forward” that occurred some 40,000 to 50,000 years ago in Europe marked end of significant biological evolution in humans. In this stunningly original account of our evolutionary history, top scholars Gregory Cochran and Henry Harpending reject this conventional wisdom and reveal that the human species has undergone a storm of genetic change much more recently. Human evolution in fact accelerated after civilization arose, they contend, and these ongoing changes have played a pivotal role in human history. They argue that biology explains the expansion of the Indo-Europeans, the European conquest of the Americas, and European Jews’ rise to intellectual prominence. …
I just received the book, so I haven’t read it yet, but I’ve been a big fan of Greg and Henry’s blog (now Greg’s blog, since Henry passed away,) for a long time. I expect to finish reading and get the relevant discussion posts up, therefore, in about two months–I’ll update the time frame as we get closer.
Please let me know if you prefer short form discussion (like our discussion of Kurzweil’s How to Build a Mind,) or long form discussion (like Auerswald’s The Code Economy,) or something in between.
I am frequently frustrated by our culture’s lack of good ethnonyms. Take “Hispanic.” It just means “someone who speaks Spanish or whose ancestors spoke Spanish.” It includes everyone from Lebanese-Mexican billionaire Carlos Slim to Japanese-Peruvian Alberto Fujimori, from Sephardi Jews to native Bolivians, from white Argentinians to black Cubans, but doesn’t include Brazilians because speaking Portuguese instead of Spanish is a really critical ethnic difference.*
*In conversation, most people use “Hispanic” to mean “Mexican or Central American who’s at least partially Native American,” but the legal definition is what colleges and government agencies are using when determining who gets affirmative action. People think “Oh, those programs are to help poor, brown people,” when in reality the beneficiaries are mostly well-off and light-skinned–people who were well-off back in their home countries.
This is the danger of using euphemisms instead of saying what you actually mean.
Our ethnonyms for other groups are equally terrible. All non-whites are often lumped together under a single “POC” label, as though Nigerian Igbo and Han Chinese were totally equivalent and fungible peoples. Whites are similarly lumped, as if a poor white from the backwoods of Georgia and a wealthy Boston Puritan had anything in common. There are technical names for these groups, used in historical or academic contexts, but if you tell the average person you hail from a mix of “Cavalier-Yeoman and Cracker ancestors,” they’re just going to be confused.
With the exception of Cajuns and recent immigrants who retain an old-world ethnic identity (eg, Irish, Jewish,) we simply lack common vernacular ethnonyms for the different white groups that settled the US–even though they are actually different.
American ethnic groups are not just Old World ethnic groups that happen to live in America. They’re real ethnicities that have developed over here during the past 500 years, but we have failed to adopt common names for them.
Woodard’s map implies a level of ethnic separation that is probably not entirely accurate, as these groups settled the American frontier in waves, creating layers of ethnicity that are thicker or thinner in different places. Today, we call these social classes, which is not entirely inaccurate.
Take the South. The area is dominated by two main ethnic blocks, Appalachians (in the mountains) and Cavalier-Plantation owners in the flatter areas. But the Cavalier area was never majority wealthy, elite plantation owners; it has always had a large contingent of middling-class whites, poor whites, and of course poor blacks. In areas of the “Deep South” where soils were poor or otherwise unsuited to cultivated, elite planters never penetrated, leaving the heartier backwoods whites–the Crackers–to their own devices.
If their ancestors spoke French, we recognize them as different, but if not, they’re just “poor”–or worse, “trash.”
Southern identity is a curious thing. Though I was born in the South (and my ancestors have lived there for over 400 years,) I have no meaningful “Southern identity” to speak of–nor do, I think, most southerners. It’s just a place; the core historical event of going to war to protect the interests of rich elites in perpetuating slavery doesn’t seem to resonate with most people I’ve met.
My interest in the region and its peoples stems not from Southern Pride, but the conventional curiosity adoptees tend to feel about their birth families: Where did I come from? What were they like? Were they good people? and Can I find a place where I feel comfortable and fit in? (No.)
My immediate biological family hails from parts of the South that never had any plantations (I had ancestors in Georgia in the 1800s, and ancestors in Virginia in the 1700s, but they’ve been dead for a while; my father lives within walking distance of his great-grandparent’s homestead.)
As previously discussed, I don’t exactly feel at home in cities; perhaps this is because calling my ancestors “farmers” is a rather generous description for folks who thought it was a good idea to move to Oklahoma during the Dust Bowl.
(By the way, the only reason the prairies are consistently farmed today is due to irrigation, drawing water up from the Ogallala and other aquifers, and we are drawing water from those aquifers much faster than it is being replenished. If we keep using water at this rate–or faster, due to population growth–WE WILL RUN OUT. The prairies will go dry and dust storms will rage again.)
To be fair, some of my kin were successful farmers when it actually rained, but some were never so sedentary. Pastoralists, ranchers, hoe-farmers–they were the sorts of people who settled frontiers and moved on when places got too crowded, who drank hard and didn’t always raise their children. They match pretty closely Richard Sapp’s description of the Florida Crackers.
From a genetic standpoint, the Crackers are either descended from borderlanders and Scotch-Irish (the pink region on the map at the top of the post,) or from folks who got along well with borderlanders and decided to move alongside them. I find it amazing that a relatively small place like Britain could produce such temperamentally different peoples as Puritans and Crackers–the former hard working, domesticated, stiff, and proper; the latter loud, liberty-loving, and more violent.
Peter Frost (evo and proud) has a theory that “core” Europe managed to decrease its homicide rates by executing criminals, thus removing them from the gene pool; the borderlands of Scotland and Ireland were perhaps beyond the reach of the hangman’s noose, or hopping the border allowed criminals to escape the police.
“The third American Revolution reached its climax in the years from 1779 to 1781. This was a rising of British borderers in the southern backcountry against American loyalists and British regulars who invaded the region. The result was a savage struggle which resembled many earlier conflicts in North Britain, with much family feuding and terrible atrocities committed on both sides. Prisoners were slaughtered, homes were burned, women were raped and even small children were put to the sword.” …
i’ve got a couple of posts related to those rambunctious folks from the backcountry whose ancestors came from the borderlands between england and scotland. libertarian crackers takes a quick look at why this group tends to love being independent and is distrustful of big gubmint — to make a long story short, the border folks married closely for much longer than the southern english — and they didn’t experience much manorialism, either (the lowland scots did, but not so much the border groups). did i mention that they’re a bit hot-headed? (not that there’s anything wrong with that! (~_^) ) see also: hatfields and mccoys. not surprising that this group’s war of independence involved “much family feuding.”
Less manorialism, less government control, less executing criminals, more cousin-marriage, more clannishness.
During the experiment, a confederate bumped some subjects and muttered ‘asshole’ at them. Cortisol (a stress hormone) and testosterone (rises in preparation for violence) were measured before and after the insult. Insulted Southerners showed big jumps in both cortisol and testosterone compared to uninsulted Southerners and insulted Northerners. The difference in psychological and physiological responses to insults was manifest in behavior. Nisbett and Cohen recruited a 6’3” 250 lb (190 cm, 115 kg) American style football player whose task was to walk down the middle of a narrow hall as subjects came the other direction. The experimenters measured how close subjects came to the football player before stepping aside. Northerners stepped aside at around 6 feet regardless of whether they had been insulted. Un-insulted Southerners stepped aside at an average distance of 9 feet, whereas insulted Southerners approached to an average of about 3 feet. Polite but prepared to be violent, un-insulted Southerners take more care, presumably because they attribute a sense of honor to the football player and are normally respectful of others’ honor. When their honor is challenged, they are prepared and willing to challenge someone at considerable risk to their own safety.”
(The bit about honor is… not right. I witnessed a lot of football games as a child, and no one ever referred to the players as “honorable.” Southerners just don’t like to get close to each other, which is very sensible if people in your area get aggressive and angry easily. The South also has a lower population density than the North, so people are used to more space.)
As my grandmother says, “You don’t get to pick your ancestors.” I don’t know what I would think of my relatives had I actually grown up with them. They have their sins, like everyone else. But from a distance, as an adult, they’re fine people and they always have entertaining stories.
“Oh, yes, yet another time I almost died…”
As for racial attitudes, if you’re curious, they vary between “probably marched for Civil Rights back in the 50s” and “has never spoken a word, good or bad, generalizing about any ethnic group.” (I have met vocally anti-black people in the South; just not in my family.) I think my relatives are more interested in various strains of Charismatic Christianity than race.
It seems rather unfortunate that Southern identity is so heavily linked to the historical interests of the Plantation Elites. After all, it did the poor whites no good to die in a war fought to protect the interests of the rich. I think the desire to take pride in your ancestors and group is normal, healthy, and instinctive, but Southerners are in an unfortunate place where that identity is heavily infused with a racial ideology most Southerners don’t even agree with.
> Be white
> Be from the south
> Not into Confederacy
> Want an identity of some sort
> Now what?
In my case, I identify with nerds. This past is not an active source of ethnic identity, nor is the Cracker lifestyle even practical in the modern day. But my ancestors have still contributed (mostly genetically) to who I am.
Well, this was going to just be an introduction to today’s anthropology selection, but it turned out rather longer than expected, so let’s just save the real anthropology for next week.
Welcome back to Anthropology Friday. Today we are continuing with Sidney L. Gulick’s Evolution of the Japanese, Social and Psychic, published in 1903. Gulick was a Puritan missionary who moved to Japan shortly after the “opening of Japan” and Meiji Restoration. He wrote at a time when very Japanese society was changing at break-neck speed and very few accounts of Japan existed at all in the West. (As usual, quotes will be in “” instead of blocks)
“Many writers have dwelt with delight on the cheerful disposition that seems so common in Japan. Lightness of heart, freedom from all anxiety for the future, living chiefly in the present, these and kindred features are pictured in glowing terms. And, on the whole, these pictures are true to life. The many flower festivals are made occasions for family picnics when all care seems thrown to the wind. There is a simplicity and a freshness and a freedom from worry that is delightful to see. But it is also remarked that a change in this regard is beginning to be observed. The coming in of Western machinery, methods of government, of trade and of education, is introducing customs and cares, ambitions and activities, that militate against the older ways. Doubtless, this too is true. If so, it but serves to establish the general proposition of these pages that the more outstanding national characteristics are largely the result of special social conditions, rather than of inherent national character. …
“Yet the Japanese are by no means given up to a cheerful view of life. Many an individual is morose and dejected in the extreme. This disposition is ever stimulated by the religious teachings of Buddhism. Its great message has been the evanescent character of the present life. Life is not worth living, it urges; though life may have some pleasures, the total result is disappointment and sorrow. Buddhism has found a warm welcome in the hearts of many Japanese. For more than a thousand years it has been exercising a potent influence on their thoughts and lives. Yet how is this consistent with the cheerful disposition which seems so characteristic of Japan? The answer is not far to seek. Pessimism is by its very nature separative, isolating, silent. Those oppressed by it do not enter into public joys. They hide themselves in monasteries, or in the home. The result is that by its very nature the actual pessimism of Japan is not a conspicuous feature of national character.
“The judgment that all Japanese are cheerful rests on shallow grounds. Because, forsooth, millions on holidays bear that appearance, and because on ordinary occasions the average man and woman seem cheerful and happy, the conclusion is reached that all are so. No effort is made to learn of those whose lives are spent in sadness and isolation. I am convinced that the Japan of old, for all its apparent cheer, had likewise its side of deep tragedy. Conditions of life that struck down countless individuals, and mental conditions which made Buddhism so popular, both point to this conclusion.”
In Japan, hikikomori (Japanese: ひきこもり or 引き籠り, lit. “pulling inward, being confined”, i.e., “acute social withdrawal“) are reclusive adolescents or adults who withdraw from social life, often seeking extreme degrees of isolation and confinement. Hikikomori refers to both the phenomenon in general and the recluses themselves. Hikikomori have been described as loners or “modern-day hermits“. Estimates reveal that nearly half a million Japanese youth have become social recluses....
According to government figures released in 2010, there are 700,000 individuals living as hikikomori with an average age of 31. Still, the numbers vary widely among experts. These include the hikikomori who are now in their 40s and have spent 20 years in isolation. This group is generally referred to as the “first-generation hikikomori.” There is concern about their reintegration into society in what is known as “the 2030 Problem,” when they are in their 60s and their parents begin to die. Additionally, the government estimates that 1.55 million people are on the verge of becoming hikikomori.Tamaki Saitō, who first coined the phrase, originally estimated that there may be over one million hikikomori in Japan, although this was not based on national survey data. Nonetheless, considering that hikikomori adolescents are hidden away and their parents are often reluctant to talk about the problem, it is extremely difficult to gauge the number accurately.
I suspect this is becoming a problem in the West, too. But back to Gulick:
“The Japanese give the double impression of being industrious and diligent on the one hand, and, on the other, of being lazy and utterly indifferent to the lapse of time. The long hours during which they keep at work is a constant wonder to the Occidental. I have often been amazed in Fukuoka to find stores and workshops open, apparently in operation, after ten and sometimes even until eleven o’clock at night, while blacksmiths and carpenters and wheelwrights would be working away as if it were morning. Many of the factories recently started keep very long hours. Indeed most of the cotton mills run day and night, having two sets of workers, who shift their times of labor every week. Those who work during the night hours one week take the day hours the following week. In at least one such factory, with which I am acquainted, the fifteen hundred girls who work from six o’clock Saturday evening until six o’clock Sunday morning, are then supposed to have twenty-four hours of rest before they begin their day’s work Monday morning; but, as a matter of fact, they must spend three or four and sometimes five hours on Sunday morning cleaning up the factory. …
“But there are equally striking illustrations of an opposite nature. The farmers and mechanics and carpenters, among regular laborers, and the entire life of the common people in their homes, give an impression of indifference to the flight of time, if not of absolute laziness. The workers seem ready to sit down for a smoke and a chat at any hour of the day. In the home and in ordinary social life, the loss of time seems to be a matter of no consequence whatever. Polite palaver takes unstinted hours, and the sauntering of the people through the street emphasizes the impression that no business calls oppress them.”
“Two other strongly contrasted traits are found in the Japanese character, absolute confidence and trustfulness on the one hand, and suspicion on the other. It is the universal testimony that the former characteristic is rapidly passing away; in the cities it is well-nigh gone. But in the country places it is still common. The idea of making a bargain when two persons entered upon some particular piece of work, the one as employer, the other as employed, was entirely repugnant to the older generation, since it was assumed that their relations as inferior and superior should determine their financial relations; the superior would do what was right, and the inferior should accept what the superior might give without a question or a murmur. Among the samurai, where the arrangement is between equals, bargaining or making fixed and fast terms which will hold to the end, and which may be carried to the courts in case of differences, was a thing practically unknown in the older civilization. Everything of a business nature was left to honor, and was carried on in mutual confidence.
“A few illustrations of this spirit of confidence from my own experience may not be without interest. On first coming to Japan, I found it usual for a Japanese who wished to take a jinrikisha to call the runner and take the ride without making any bargain, giving him at the end what seemed right. And the men generally accepted the payment without question. I have found that recently, unless there is some definite understanding arrived at before the ride, there is apt to be some disagreement, the runner presuming on the hold he has, by virtue of work done, to get more than is customary. This is especially true in case the rider is a foreigner. Another set of examples in which astonishing simplicity and confidence were manifested was in the employment of evangelists. I have known several instances in which a full correspondence with an evangelist with regard to his employment was carried on, and the settlement finally concluded, and the man set to work without a word said about money matters. It need hardly be said that no foreigner took part in that correspondence. …
“This confidence and trustfulness were the product of a civilization resting on communalistic feudalism; the people were kept as children in dependence on their feudal lord; they had to accept what he said and did; they were accustomed to that order of things from the beginning and had no other thought; on the whole too, without doubt, they received regular and kindly treatment. Furthermore, there was no redress for the peasant in case of harshness; it was always the wise policy, therefore, for him to accept whatever was given without even the appearance of dissatisfaction. This spirit was connected with the dominance of the military class. Simple trustfulness was, therefore, chiefly that of the non-military classes. The trustfulness of the samurai sprang from their distinctive training. As already mentioned, when drawing up a bond in feudal times, in place of any tangible security, the document would read, “If I fail to do so and so, you may laugh at me in public.”
“Since the overthrow of communal feudalism and the establishment of an individualistic social order, necessitating personal ownership of property, and the universal use of money, trustful confidence is rapidly passing away. Everything is being more and more accurately reduced to a money basis. The old samurai scorn for money seems to be wholly gone, an astonishing transformation of character. Since the disestablishment of the samurai class many of them have gone into business. Not a few have made tremendous failures for lack of business instinct, being easily fleeced by more cunning and less honorable fellows who have played the “confidence” game most successfully; others have made equally great successes because of their superior mental ability and education. The government of Japan is to-day chiefly in the hands of the descendants of the samurai class. …
“Passing now from the character of trustful confidence, we take up its opposite, suspiciousness. The development of this quality is a natural result of a military feudalism such as ruled Japan for hundreds of years. Intrigue was in constant use when actual war was not being waged. In an age when conflicts were always hand to hand, and the man who could best deceive his enemy as to his next blow was the one to carry off his head, the development of suspicion, strategy, and deceit was inevitable. The most suspicious men, other things being equal, would be the victors; they, with their families, would survive and thus determine the nature of the social order. The more than two hundred and fifty clans and “kuni,” “clan territory,” into which the land was divided, kept up perpetual training in the arts of intrigue and subtlety which are inevitably accompanied by suspicion.”
EvX: You can almost hear the HBD argument being made…
“Modern manifestations of this characteristic are frequent. Not a cabinet is formed, but the question of its make-up is discussed from the clannish standpoint. Even though it is now thirty years since the centralizing policy was entered upon and clan distinctions were effectually broken down, yet clan suspicion and jealousy is not dead.”
“The foreigner is impressed by the constant need of care in conversation, lest he be thought to mean something more or other than he says. When we have occasion to criticise anything in the Japanese, we have found by experience that much more is inferred than is said. Shortly after my arrival in Japan I was advised by one who had been in the land many years to be careful in correcting a domestic or any other person sustaining any relation to myself, to say not more than one-tenth of what I meant, for the other nine-tenths would be inferred. Direct and perfectly frank criticism and suggestion, such as prevail among Anglo-Americans at least, seem to be rare among the Japanese.”
I’m about halfway through Caleb Everett’s Numbers and the Making of Us: Counting and the Course of Human Cultures. Everett begins the book with a lengthy clarification that he thinks everyone in the world has equal math abilities, some of us just happen to have been exposed to more number ideas than others. Once that’s out of the way, the book gets interesting.
When did humans invent numbers? It’s hard to say. We have notched sticks from the Paleolithic, but no way to tell if these notches were meant to signify numbers or were just decorated.
The slightly more recent Ishango, Lebombo, and Wolf bones (30,000 YA, Czech Republic) seem more likely to indicate that someone was at least counting–if not keeping track–of something.
The Ishango bone (estimated 20,000 years old, found in the Democratic Republic of the Congo near the headwaters of the Nile,) has three sets of notches–two sets total to 60, the third to 48. Interestingly, the notches are grouped, with both sets of sixty composed of primes: 19 + 17 + 13 + 11 and 9 + 19 + 21 + 11. The set of 48 contains groups of 3, 6, 4, 8, 10, 5, 5, and 7. Aside from the stray seven, the sequence tantalizingly suggests that someone was doubling numbers.
The Ishango bone also has a quartz point set into the end, which perhaps allowed it to be used for scraping, drawing, or etching–or perhaps it just looked nice atop someone’s decorated bone.
The Lebombo bone, (estimated 43-44,2000 years old, found near the border between South Africa and Swaziland,) is quite similar to the Ishango bone, but only contains 29 notches (as far as we can tell–it’s broken.)
I’ve seen a lot of people proclaiming “Scientists think it was used to keep track of menstrual cycles. Menstruating African women were the first mathematicians!” so I’m just going to let you in on a little secret: scientists have no idea what it was for. Maybe someone was just having fun putting notches on a bone. Maybe someone was trying to count all of their relatives. Maybe someone was counting days between new and full moons, or counting down to an important date.
Without a far richer archaeological assembly than one bone, we have no idea what this particular person might have wanted to count or keep track of. (Also, why would anyone want to keep track of menstrual cycles? You’ll know when they happen.)
The Wolf bone (30,000 years old, Czech Republic,) has received far less interest from folks interested in proclaiming that menstruating African women were the first mathematicians, but is a nice looking artifact with 60 notches–notches 30 and 31 are significantly longer than the others, as though marking a significant place in the counting (or perhaps just the middle of the pattern.)
Everett cites another, more satisfying tally stick: a 10,000 year old piece of antler found in the anoxic waters of Little Salt Spring, Florida. The antler contains two sets of marks: 28 (or possibly 29–the top is broken in a way that suggests another notch might have been a weak point contributing to the break) large, regular, evenly spaced notches running up the antler, and a much smaller set of notches set beside and just slightly beneath the first. It definitely looks like someone was ticking off quantities of something they wanted to keep track of.
Here’s an article with more information on Little Salt Spring and a good photograph of the antler.
I consider the bones “maybes” and the Little Salt Spring antler a definite for counting/keeping track of quantities.
Everett also mentions a much more recent and highly inventive tally system: the Incan quipu.
A quipu is made of knotted strings attached to one central string. A series of knots along the length of each string denotes numbers–one knot for 1, two for 2, etc. The knots are grouped in clusters, allowing place value–first cluster for the ones, second for the tens, third for hundreds, etc. (And a blank space for a zero.)
Thus a sequence of 2 knots, 4 knots, a space, and 5 knots = 5,402
The Incas, you see, had an empire to administer, no paper, but plenty of lovely alpaca wool. So being inventive people, they made do.
Everett then discusses the construction of names for numbers/base systems in different languages. Many languages use a combination of different bases, eg, “two twos” for four, (base 2,) “two hands” to signify 10 (base 5,) and from there, words for multiples of 10 or 20, (base 10 or 20,) can all appear in the same language. He argues convincingly that most languages derived their counting words from our original tally sticks: fingers and toes, found in quantities of 5, 10, and 20. So the number for 5 in a language might be “one hand”, the number for 10, “Two hands,” and the number for 20 “one person” (two hands + two feet.) We could express the number 200 in such a language by saying “two hands of one person”= 10 x 20.
(If you’re wondering how anyone could come up with a base 60 system, such as we inherited from the Babylonians for telling time, try using the knuckles of the four fingers on one hand  times the fingers of the other hand  to get 60.)
Which begs the question of what counts as a “number” word (numeral). Some languages, it is claimed, don’t have words for numbers higher than 3–but put out an array of 6 objects, and their speakers can construct numbers like “three twos.” Is this a number? What about the number in English that comes after twelve: four-teen, really just a longstanding mispronunciation of four and ten?
Perhaps a better question than “Do they have a word for it,” is “Do they have a common, easy to use word for it?” English contains the world nonillion, but you probably don’t use it very often (and according to the dictionary, a nonillion is much bigger in Britain than in the US, which makes it especially useless.) By contrast, you probably use quantities like a hundred or a thousand all the time, especially when thinking about household budgets.
Roman Numerals are really just an advanced tally system with two bases: 5 and 10. IIII are clearly regular tally marks. V (5) is similar to our practice of crossing through four tally marks. X (10) is two Vs set together. L (50) is a rotated V. C (100) is an abbreviation for the Roman word Centum, hundred. (I, V, X, and L are not abbreviations.) I’m not sure why 500 is D; maybe just because D follows C and it looks like a C with an extra line. M is short for Mille, or thousand. Roman numerals are also fairly unique in their use of subtraction in writing numbers, which few people do because it makes addition horrible. Eg, IV and VI are not the same number, nor do they equal 15 and 51. No, they equal 4 (v-1) and 6 (v+1,) respectively. Adding or multiplying large Roman numerals quickly becomes cumbersome; if you don’t believe me, try XLVII times XVIII with only a pencil and paper.
Now imagine you’re trying to run an empire this way.
You’re probably thinking, “At least those quipus had a zero and were reliably base ten,” about now.
Interestingly, the Mayans (and possibly the Olmecs) already had a proper symbol that they used for zero in their combination base-5/base-20 system with pretty functional place value at a time when the Greeks and Romans did not (the ancient Greeks were philosophically unsure about this concept of a “number that isn’t there.”)
(Note: given the level of sophistication of Native American civilizations like the Inca, Aztec, and Maya, and the fact that these developed in near total isolation, they must have been pretty smart. Their current populations appear to be under-performing relative to their ancestors.)
But let’s let Everett have a chance to speak:
Our increasingly refined means of survival and adaptation are the result of a cultural ratchet. This term, popularized by Duke University psychologist and primatologist Michael Tomasello, refers to the fact that humans cooperatively lock in knowledge from one generation to the next, like the clicking of a ratchet. In other word, our species’ success is due in large measure to individual members’ ability to learn from and emulate the advantageous behavior of their predecessors and contemporaries in their community. What makes humans special is not simply that we are so smart, it is that we do not have to continually come up with new solutions to the same old problems. …
Now this is imminently reasonable; I did not invent the calculus, nor could I have done so had it not already existed. Luckily for me, Newton and Leibniz already invented it and I live in a society that goes to great lengths to encode math in textbooks and teach it to students.
I call this “cultural knowledge” or “cultural memory,” and without it we’d still be monkeys with rocks.
The importance of gradually acquired knowledge stored in the community, culturally reified but not housed in the mind of any one individual, crystallizes when we consider cases in which entire cultures have nearly gone extinct because some of their stored knowledge dissipated due to the death of individuals who served as crucial nodes in their community’s knowledge network. In the case of the Polar Inuit of Northwest Greenland, population declined in the mid-nineteenth century after an epidemic killed several elders of the community. These elders were buried along with their tool sand weapons, in accordance with local tradition, and the Inuits’ ability to manufacture the tools and weapons in question was severely compromised. … As a result, their population did not recover until about 40 years later, when contact with another Inuit group allowed for the restoration of the communal knowledge base.
The first big advance, the one that separates us from the rest of the animal kingdom, was language itself. Yes, other animals can communicate–whales and birds sing; bees do their waggle dance–but only humans have full-fledged, generative language which allows us to both encode and decode new ideas with relative ease. Language lets different people in a tribe learn different things and then pool their ideas far more efficiently than mere imitation.
The next big leap was the development of visual symbols we could record–and read–on wood, clay, wax, bones, cloth, cave walls, etc. Everett suggests that the first of these symbols were likely tally marks such us those found on the Lebombo bone, though of course the ability to encode a buffalo on the wall of the Lascaux cave, France, was also significant. From these first symbols we developed both numbers and letters, which eventually evolved into books.
Books are incredible. Books are like external hard drives for your brain, letting you store, access, and transfer information to other people well beyond your own limits of memorization and well beyond a human lifetime. Books reach across the ages, allowing us to read what philosophers, poets, priests and sages were thinking about a thousand years ago.
Recently we invented an even more incredible information storage/transfer device: computers/the internet. To be fair, they aren’t as sturdy as clay tablets, (fired clay is practically immortal,) but they can handle immense quantities of data–and make it searchable, an incredibly important task.
But Everett tries to claim that cultural ratchet is all there is to human mathematical ability. If you live in a society with calculus textbooks, then you can learn calculus, and if you don’t, you can’t. Everett does not want to imply that Amazonian tribesmen with no words for numbers bigger than three are in any way less able to do math than the Mayans with their place value system and fancy zero.
But this seems unlikely for two reasons. First, we know very well that even in societies with calculus textbooks, not everyone can make use of them. Even among my own children, who have been raised with about as similar an environment as a human can make and have very similar genetics, there’s a striking difference in intellectual strengths and weaknesses. Humans are not identical in their abilities.
Moreover, we know that different mental tasks are performed in different, specialized parts of the brain. For example, we decode letters in the “visual word form area” of the brain; people whose VWAs have been damaged can still read, but they have to use different parts of their brains to work out the letters and they end up reading more slowly than they did before.
Memorably, before he died, the late Henry Harpending (of West Hunter) had a stroke while in Germany. He initially didn’t notice the stroke because it was located in the part of the brain that decodes letters into words, but since he was in Germany, he didn’t expect to read the words, anyway. It was only when he looked at something written in English later that day that he realized he couldn’t read it, and soon after I believe he passed out and was taken to the hospital.
Why should our brains have a VWA at all? It’s not like our primate ancestors did a whole lot of reading. It turns out that the VWA is repurposed from the part of our brain that recognizes faces :)
Likewise, there are specific regions of the brain that handle mathematical tasks. People who are better at math not only have more gray matter in these regions, but they also have stronger connections between them, letting the work together in harmony to solve different problems. We don’t do math by just throwing all of our mental power at a problem, but by routing it through specific regions of our brain.
Interestingly, humans and chimps differ in their ability to recognize faces and perceive emotions. (For anatomical reasons, chimps are more inclined to identify each other’s bottoms than each other’s faces.) We evolved the ability to recognize faces–the region of our brain we use to decode letters–when we began walking upright and interacting to each other face to face, though we do have some vestigial interest in butts and butt-like regions (“My eyes are up here.”) Our brains have evolved over the millenia to get better at specific tasks–in this case, face reading, a precursor to decoding symbolic language.
And there is a tremendous quantity of evidence that intelligence is at least partly genetic–estimates for the heritablity of intelligence range between 60 and 80%. The rest of the variation–the environmental part–looks to be essentially random chance, such as accidents, nutrition, or perhaps your third grade teacher.
So, yes, we absolutely can breed people for mathematical or linguistic ability, if that’s what the environment is selecting for. By contrast, if there have been no particular mathematical or linguistic section pressures in an environment (a culture with no written language, mathematical notation, and very few words for numbers clearly is not experiencing much pressure to use them), then you won’t select for such abilities. The question is not whether we can all be Newtons, (or Leibnizes,) but how many Newtons a society produces and how many people in that society have the potential to understand calculus, given the chance.
Just looking at the state of different societies around the world (including many indigenous groups that live within and have access to modern industrial or post-industrial technologies), there is clear variation in the average abilities of different groups to build and maintain complex societies. Japanese cities are technologically advanced, clean, and violence-free. Brazil, (which hasn’t even been nuked,) is full of incredibly violent, unsanitary, poorly-constructed favelas. Some of this variation is cultural, (Venezuela is doing particularly badly because communism doesn’t work,) or random chance, (Saudi Arabia has oil,) but some of it, by necessity, is genetic.
But if you find that a depressing thought, take heart: selective pressures can be changed. Start selecting for mathematical and verbal ability (and let everyone have a shot at developing those abilities) and you’ll get more mathematical and verbal abilities.
But this is getting long, so let’s continue our discussion next week.
New tests on two ancient teeth found in a cave in Indonesia more than 120 years ago have established that early modern humans arrived in Southeast Asia at least 20,000 years earlier than scientists previously thought, according to a new study. …
The findings push back the date of the earliest known modern human presence in tropical Southeast Asia to between 63,000 and 73,000 years ago. The new study also suggests that early modern humans could have made the crossing to Australia much earlier than the commonly accepted time frame of 60,000 to 65,000 years ago.
I would like to emphasize that nothing based on a couple of teeth is conclusive, “settled,” or “proven” science. Samples can get contaminated, machines make errors, people play tricks–in the end, we’re looking for the weight of the evidence.
I am personally of the opinion that there were (at least) two ancient human migrations into south east Asia, but only time will tell if I am correct.
We investigated the genetic architecture of family relationship satisfaction and friendship satisfaction in the UK Biobank. …
In the DSM-55, difficulties in social functioning is one of the criteria for diagnosing conditions such as autism, anorexia nervosa, schizophrenia, and bipolar disorder. However, little is known about the genetic architecture of social relationship satisfaction, and if social relationship dissatisfaction genetically contributes to risk for psychiatric conditions. …
We present the results of a large-scale genome-wide association study of social
relationship satisfaction in the UK Biobank measured using family relationship satisfaction and friendship satisfaction. Despite the modest phenotypic correlations, there was a significant and high genetic correlation between the two phenotypes, suggesting a similar genetic architecture between the two phenotypes.
Note: the two “phenotypes” here are “family relationship satisfaction” and “friendship satisfaction.”
We first investigated if the two phenotypes were genetically correlated with
psychiatric conditions. As predicted, most if not all psychiatric conditions had a significant negative correlation for the two phenotypes. … We observed significant negative genetic correlation between the two phenotypes and a large cross-condition psychiatric GWAS38. This underscores the importance of social relationship dissatisfaction in psychiatric conditions. …
In other words, people with mental illnesses generally don’t have a lot of friends nor get along with their families.
One notable exception is the negative genetic correlation between measures of cognition and the two phenotypes. Whilst subjective wellbeing is positively genetically correlated with measures of cognition, we identify a small but statistically significant negative correlation between measures of correlation and the two phenotypes.
Are they saying that smart people have fewer friends? Or that dumber people are happier with their friends and families? I think they are clouding this finding in intentionally obtuse language.
A recent study highlighted that people with very high IQ scores tend to report lower satisfaction with life with more frequent socialization.
Oh, I think I read that one. It’s not the socialization per se that’s the problem, but spending time away from the smart person’s intellectual activities. For example, I enjoy discussing the latest genetics findings with friends, but I don’t enjoy going on family vacations because they are a lot of work that does not involve genetics. (This is actually something my relatives complain about.)
…alleles that increase the risk for schizophrenia are in the same haplotype as
alleles that decrease friendship satisfaction. The functional consequences of this locus must be formally tested. …
Loss of function mutations in these genes lead to severe biochemical consequences, and are implicated in several neuropsychiatric conditions. For
example, de novo loss of function mutations in pLI intolerant genes confers significant risk for autism. Our results suggest that pLI > 0.9 genes contribute to psychiatric risk through both common and rare genetic variation.
It was only two years ago that researchers found the first ancient human genome in Africa: a skeleton in a cave in Ethiopia yielded DNA that turned out to be 4,500 years old.
On Thursday, an international team of scientists reported that they had recovered far older genes from bone fragments in Malawi dating back 8,100 years. The researchers also retrieved DNA from 15 other ancient people in eastern and southern Africa, and compared the genes to those of living Africans.
We assembled genome-wide data from 16 prehistoric Africans. We show that the anciently divergent lineage that comprises the primary ancestry of the southern African San had a wider distribution in the past, contributing approximately two-thirds of the ancestry of Malawi hunter-gatherers ∼8,100–2,500 years ago and approximately one-third of the ancestry of Tanzanian hunter-gatherers ∼1,400 years ago.
The San are also known as the Bushmen, a famous group of recent hunter-gatherers from southern Africa.
We document how the spread of farmers from western Africa involved complete replacement of local hunter-gatherers in some regions…
…and we track the spread of herders by showing that the population of a ∼3,100-year-old pastoralist from Tanzania contributed ancestry to people from northeastern to southern Africa, including a ∼1,200-year-old southern African pastoralist…
Whereas the two individuals buried in ∼2,000 BP hunter-gatherer contexts in South Africa share ancestry with southern African Khoe-San populations in the PCA, 11 of the 12 ancient individuals who lived in eastern and south-central Africa between ∼8,100 and ∼400 BP form a gradient of relatedness to the eastern African Hadza on the one hand and southern African Khoe-San on the other (Figure 1A).
The Hadza are a hunter-gatherer group from Tanzania who are not obviously related to any other people. Their language has traditionally been classed alongside the languages of the KhoiSan/Bushmen people because they all contain clicks, but the languages otherwise have very little in common and Hadza appears to be a language isolate, like Basque.
The genetic cline correlates to geography, running along a north-south axis with ancient individuals from Ethiopia (∼4,500 BP), Kenya (∼400 BP), Tanzania (both ∼1,400 BP), and Malawi (∼8,100–2,500 BP), showing increasing affinity to southern Africans (both ancient individuals and present-day Khoe-San). The seven individuals from Malawi show no clear heterogeneity, indicating a long-standing and distinctive population in ancient Malawi that persisted for at least ∼5,000 years (the minimum span of our radiocarbon dates) but which no longer exists today. …
We find that ancestry closely related to the ancient southern Africans was present much farther north and east in the past than is apparent today. This ancient southern African ancestry comprises up to 91% of the ancestry of Khoe-San groups today (Table S5), and also 31% ± 3% of the ancestry of Tanzania_Zanzibar_1400BP, 60% ± 6% of the ancestry of Malawi_Fingira_6100BP, and 65% ± 3% of the ancestry of Malawi_Fingira_2500BP (Figure 2A). …
Both unsupervised clustering (Figure 1B) and formal ancestry estimation (Figure 2B) suggest that individuals from the Hadza group in Tanzania can be modeled as deriving all their ancestry from a lineage related deeply to ancient eastern Africans such as the Ethiopia_4500BP individual …
So what’s up with the Tanzanian expansion mentioned in the summary?
Western-Eurasian-related ancestry is pervasive in eastern Africa today … and the timing of this admixture has been estimated to be ∼3,000 BP on average… We found that the ∼3,100 BP individual… associated with a Savanna Pastoral Neolithic archeological tradition, could be modeled as having 38% ± 1% of her ancestry related to the nearly 10,000-year-old pre-pottery farmers of the Levant … These results could be explained by migration into Africa from descendants of pre-pottery Levantine farmers or alternatively by a scenario in which both pre-pottery Levantine farmers and Tanzania_Luxmanda_3100BP descend from a common ancestral population that lived thousands of years earlier in Africa or the Near East. We fit the remaining approximately two-thirds of Tanzania_Luxmanda_3100BP as most closely related to the Ethiopia_4500BP…
…present-day Cushitic speakers such as the Somali cannot be fit simply as having Tanzania_Luxmanda_3100BP ancestry. The best fitting model for the Somali includes Tanzania_Luxmanda_3100BP ancestry, Dinka-related ancestry, and 16% ± 3% Iranian-Neolithic-related ancestry (p = 0.015). This suggests that ancestry related to the Iranian Neolithic appeared in eastern Africa after earlier gene flow related to Levant Neolithic populations, a scenario that is made more plausible by the genetic evidence of admixture of Iranian-Neolithic-related ancestry throughout the Levant by the time of the Bronze Age …and in ancient Egypt by the Iron Age …
There is then a discussion of possible models of ancient African population splits (were the Bushmen the first? How long have they been isolated?) I suspect the more ancient African DNA we uncover, the more complicated the tree will become, just as in Europe and Asia we’ve discovered Neanderthal and Denisovan admixture.
They also compared genomes to look for genetic adaptations and found evidence for selection for taste receptors and “response to radiation” in the Bushmen, which the authors note “could be due to exposure to sunlight associated with the life of the ‡Khomani and Ju|’hoan North people in the Kalahari Basin, which has become a refuge for hunter-gatherer populations in the last millenia due to encroachment by pastoralist and agriculturalist groups.”
(The Bushmen are lighter than Bantus, with a more golden or tan skin tone.)
They also found evidence of selection for short stature among the Pygmies (which isn’t really surprising to anyone, unless you thought they had acquired their heights by admixture with another very short group of people.)
Overall, this is a great paper and I encourage you to RTWT, especially the pictures/graphs.
Examining ethnically diverse African genomes, we identify variants in or near SLC24A5, MFSD12, DDB1, TMEM138, OCA2 and HERC2 that are significantly associated with skin pigmentation. Genetic evidence indicates that the light pigmentation variant at SLC24A5 was introduced into East Africa by gene flow from non-Africans. At all other loci, variants associated with dark pigmentation in Africans are identical by descent in southern Asian and Australo-Melanesian populations. Functional analyses indicate that MFSD12 encodes a lysosomal protein that affects melanogenesis in zebrafish and mice, and that mutations in melanocyte-specific regulatory regions near DDB1/TMEM138 correlate with expression of UV response genes under selection in Eurasians.
I’ve had an essay on the evolution of African skin tones sitting in my draft folder for ages because this research hadn’t been done. There’s plenty of research on European and Asian skin tones (skin appears to have significantly lightened around 10,000 years ago in Europeans,) but much less on Africans. Luckily for me, this paper fixes that.
Looks like SLC24A5 is related to that Levantine/Iranian back-migration into Africa documented in the first paper.
Zoroastrianism is one of the world’s oldest surviving religions and possibly its first monotheistic one. It emerged in now-Iran about 3,000 years ago, but following the Arab (Islamic) conquest of Persia, many Zoroastrians migrated to India, where they became known as the Parsi (from the word for “Persian.”) To be clear, where this post refers to “Parsis” it means the specific Zoroastrian community in India, and where it refers to “Iranian Zoroastrians” it means the Zoroastrians currently living in Iran.
Although Zoroastrianism was once the official state religion of Persia, today only about 190,000 believers remain (according to Wikipedia,) and their numbers are declining.
Portuguese physician Garcia de Orta observed in 1563 that “there are merchants … in the kingdom of Cambaia … known as Esparcis. We Portuguese call them Jews, but they are not so. They are Gentios.”
Another parallel: Ashkenazi Jews and Parsis are both reported to be very smart. Famous Parsis include Queen Guitarist Freddy Mercury, nuclear physicist Homi J. Bhabha, and our Harvard-employed friend, Homi K. Bhabha.
Historical records indicate that migrants from Persia brought Zoroastrianism to India, but there is debate over the timing of these migrations. Here we present genome-wide autosomal, Y chromosome, and mitochondrial DNA data from Iranian and Indian Zoroastrians and neighboring modern-day Indian and Iranian populations and conduct a comprehensive genome-wide genetic analysis in these groups. … we find that Zoroastrians in Iran and India have increased genetic homogeneity relative to other sampled groups in their respective countries, consistent with their current practices of endogamy. Despite this, we infer that Indian Zoroastrians (Parsis) intermixed with local groups sometime after their arrival in India, dating this mixture to 690–1390 CE and providing strong evidence that Iranian Zoroastrian ancestry was maintained primarily through the male line.
Note that all diasporic–that is, migrant–groups appear to be heavily male. Women tend to stay put while men move and take new wives in their new homelands.
By making use of the rich information in DNA from ancient human remains, we also highlight admixture in the ancestors of Iranian Zoroastrians dated to 570 BCE–746CE, older than admixture seen in any other sampled Iranian group, consistent with a long-standing isolation of Zoroastrians from outside groups. …
Admixture with whom? (Let’s just read the paper and see if it answers the question):
Furthermore, a recent study using genome-wide autosomal DNA found that haplotype patterns in Iranian Zoroastrians matched more than other modern Iranian groups to a high-coverage early Neolithic farmer genome from Iran …
A study of four restriction fragment length polymorphisms (RFLPs) suggested a closer genetic affinity of Parsis to Southern Europeans than to non-Parsis from Bombay. Furthermore, NRY haplotype analysis and patterns of variation at the HLA locus in the Parsis of Pakistan support a predominately Iranian origin. …
In (1) and (2), we detected admixture in the Parsis dated to 27 (range: 17–38) and 32 (19–44) generations ago, respectively, in each case between one predominantly Indian-like source and one predominantly Iranian-like source. This large contribution from an Iranian-like source (∼64%–76%) is not seen in any of our other 7 Indian clusters, though we detect admixture in each of these 7 groups from wide-ranging sources related to modern day individuals from Bangladesh, Cambodia, Europe, Pakistan, or of Jewish heritage (Figures 2 and S7, Tables S5–S7). For Iranian Zoroastrians, we detect admixture only under analysis (2), occurring 66 (42–89) generations ago between a source best genetically explained as a mixture of modern-day Croatian and Cypriot samples, and a second source matching to the Neolithic Iranian farmer WC1. … The two Iranian Zoroastrians that had been excluded as outliers exhibited admixture patterns more similar to the Lebanese, Turkish Jews, or Iranian Bandari individuals than to Zoroastrians (Table S8).
If I assume a generation is about 25 years long, 27 generations was about 675 years ago; 32 was about 800 years ago. (Though given the wide range on these dates, perhaps we should estimate between 425 and 1,100 years ago.) This sounds consistent with Parsis taking local wives after they arrived in India between the 8th and 10th century CE (after the Arab conquest of Perisa.) Also consistently, this admixture isn’t found in Iranian Zoroastrians.
The Iranians’ admixture occurred about 1,050 and 2,225 years ago, which is an awfully broad time range. Could Croatian or Cypriot migrants have arrived due to the Greek/Roma/ Byzantine Empires? Were they incorporated into the Persian Empire as a result of its territorial conquests or the Arab conquest? Or were they just long-distance merchants who happened to wander into the area?
The authors found that Parsi priests had “the lowest gene diversity values of all population samples studied for both Y and mtDNA,” though they didn’t have enough Iranian Zoroastrian priest samples to compare them to Parsi priests. (I bet this is similar to what you’d find if you sampled Orthodox rabbis.)
Finally, in the genetic selection and diseases section, the authors write:
In the case of the Iranian Zoroastrians, … some of the most significant SNPs… are located upstream of gene SLC39A10 … with an important role in humoral immunity61 or in CALB2 … which plays a major role in the cerebellar physiology.62
With regard to the positive selection tests on Parsis versus India Hindu/Gujarati groups, the most significant SNPs were embedded in WWOX … associated with neurological disorders like early epilepsy … and in a region in chromosome 20 … (see Table S11 for a complete list). …
Genetic isolation and endogamous practices can be associated with higher frequencies of disease prevalence. For example, there are reports claiming a high recurrence of diseases such as diabetes among the Iranian Zoroastrians, and Parkinson, colon cancer, or the deficiency of G6PD, an enzyme that triggers the sudden reduction of red blood cells, among the Parsis.
However, the authors warn that these results are weak (these are rare conditions in an already small population) and cannot not be depended upon.
There are three categories of supersars who seem to attract excessive female interest. The first is actors, who of course are selected for being abnormally attractive and put into romantic and exciting narratives that our brains subconsciously interpret as real. The second are sports stars and other athletes, whose ritualized combat and displays of strength obviously indicate their genetic “fitness” for siring and providing for children.
The third and strangest category is professional musicians, especially rock stars.
I understand why people want to pass athletic abilities on to their children, but what is the evolutionary importance of musical talent? Does music tap into some deep, fundamental instinct like a bird’s attraction to the courtship song of its mate? And if so, why?
There’s no denying the importance of music to American courtship rituals–not only do people visit bars, clubs, and concerts where music is being played in order to meet potential partners, but they also display musical tastes on dating profiles in order to meet musically-like-minded people.
Of all the traits to look for in a mate, why rate musical taste so highly? And why do some people describe their taste as, “Anything but rap,” or “Anything but country”?
At least when I was a teen, musical taste was an important part of one’s “identity.” There were goths and punks, indie scene kids and the aforementioned rap and country fans.
Is there actually any correlation between musical taste and personality? Do people who like slow jazz get along with other slow jazz fans better than fans of classical Indian? Or is this all compounded by different ethnic groups identifying with specific musical styles?
Obviously country correlates with Amerikaner ancestry; rap with African American. I’m not sure what ancestry is biggest fans of Die Antwoord. Heavy Metal is popular in Finno-Scandia. Rock ‘n Roll got its start in the African American community as “Race Music” and became popular with white audiences after Elvis Presley took up the guitar.
While Europe has a long and lovely musical heritage, it’s indisputable that African Americans have contributed tremendously to American musical innovation.
Here are two excerpts on the subject of music and dance in African societies:
Both of these h/t HBD Chick and my apologies in advance if I got the sources reversed.
One of the major HBD theories holds that the three races vary–on average–in the distribution of certain traits, such as age of first tooth eruption or intensity of an infant’s response to a tissue placed over its face. Sub-Saharan Africans and Asians are considered two extremes in this distribution, with whites somewhere in between.
If traditional African dancing involves more variety in rhythmic expression than traditional European, does traditional Asian dance involve less? I really know very little about traditional Asian music or dance of any kind, but I would not be surprised to see some kind of continuum affected by whether a society traditionally practiced arranged marriages. Where people chose their own mates, it seems like they display a preference for athletic or musically talented mates (“sexy” mates;) when parents chose mates, they seem to prefer hard-working, devout, “good providers.”
Even in traditional European and American society, where parents played more of a role in courtship than they do today, music still played a major part. Young women, if their families could afford it, learned to play the piano or other instruments in order to be “accomplished” and thus more attractive to higher-status men; young men and women often met and courted at musical events or dances organized by the adults.
It is undoubtedly true that music stirs the soul and speaks to the heart, but why?
I’m starting some new IRL projects (that have nothing to do with the blog and won’t be discussed here.) It’s a big time commitment and if all goes well, I’m going to be really busy for the foreseeable future.
Right now I have no idea how this will affect the blog, whether I’ll be figure out how to balance my time and keep up my regular schedule or will need to cut back. I’ll let you know when I find out.
(Update: hooo boy has life been kicking my butt.)
In the meanwhile, here’s a graph of the incidence of people who never develop their permanent third molars, broken down by continent (I assume N. and S. America are sampled from Native American populations.)
This is not the same as not getting your wisdom teeth, though I’d wager a graph of that would look similar.
(“agenesis”= does not begin; “m3″= third molar.)
And a simple graph of heights in the US, Europe and Sweden over the past … 2000 years.
I propose that the recent increase in heights isn’t just because of better nutrition/more food/more milk and protein in the diet, but also because fewer women die giving birth to large babies now that we have c-sections, and large babies likely grow into large adults.
Observations of chimpanzees (Pan troglodytes) and bonobos (Pan paniscus) provide valuable comparative data for understanding the significance of conspecific killing. … Lethal violence is sometimes concluded to be the result of adaptive strategies, such that killers ultimately gain fitness benefits by increasing their access to resources such as food or mates. Alternatively, it could be a non-adaptive result of human impacts, such as habitat change or food provisioning. To discriminate between these hypotheses we compiled information from 18 chimpanzee communities and 4 bonobo communities studied over five decades. Our data include 152 killings (n = 58 observed, 41 inferred, and 53 suspected killings) by chimpanzees in 15 communities and one suspected killing by bonobos. We found that males were the most frequent attackers (92% of participants) and victims (73%); most killings (66%) involved intercommunity attacks; and attackers greatly outnumbered their victims (median 8:1 ratio). Variation in killing rates was unrelated to measures of human impacts. Our results are compatible with previously proposed adaptive explanations for killing by chimpanzees, whereas the human impact hypothesis is not supported.
…He produces a list of recent killings he contends are the result of feuding families – not just random acts of violence in a country awash with guns, but the result of continued adherence to an ancient Albanian code of justice known as the “kanun”, or canon.
There is a farmer who was killed after cutting down his neighbour’s tree, a lover who shot both his girlfriend’s brothers after being denied her hand in marriage, and a returning migrant worker gunned down after he went back to his village, reigniting a decades-old feud.
Such are the rules of the “kanun”, a tribal code of 1,262 rules laid down by the 15th-century Albanian nobleman Lekë Dukagjini, which ordains that “spilled blood must be met with spilled blood”.
But while the Kanun stories remain part of Albania’s cultural and historical DNA, they are also a source of growing concern for Britain’s asylum tribunals. Since 2012 tens of thousands of Albanians have migrated to Europe, many seeking asylum on the basis that they are afraid for their lives as a result of “blood feuds”. …
Herodotus, writing in the Histories, Book II.53 around 450 BCE, remarked that Homer “lived, as I believe, not more than 400 years ago.” Many modern classicists and historians prefer a more recent, mid-8th century date for the Iliad. We (Altschuler, Calude, Meade, & Pagel, 2013) decided to try to estimate a date for the Iliad by investigating patterns of cognacy among the 200 words of Swadesh’s (1952) fundamental vocabulary in three languages: Modern Greek, Homeric Greek from Homer’s Iliad, and Hittite, a language distantly related to both modern and Homeric Greek.
We first recorded whether each word in the Swadesh list was cognate or not between pairs of the three languages. Then, we solved for the date in history that was the most likely for the Iliad, given our knowledge of the rates of change of the words and the patterns of cognacy we observed. Our calculation suggested that the original text of the Iliad was released in approximately 762 BCE. This date is in close agreement with classicists’ and historians’ beliefs arrived at independently by studying historical references and the nature of Homeric Greek as expressed in the Iliad.
E: … I know in terms of iodine deficiency, pre-modern-transport and storage, distance from the sea makes a big difference. And probably in a well-ordered place with relatively good transport like the Roman Empire at its height, fish sauce must have been the easiest way to get the benefits to the most people, regardless of distance from the ocean. (I wonder if there would be any way to test iodine deficiency in bodies in the Alps before, during, and after the Roman Empire…)
Someone get on testing bodies for iodine deficiency!
