John Derbyshire On Nicholas Wade’s A TROUBLESOME INHERITANCE – A Small, But Significant, Step For Race Realism“Wade raises high the banner of race realism and charges head-on into the massed ranks of the SSSM. He states his major premise up front, on page two: ‘New analyses of the human genome have established that human evolution has been recent, copious, and regional.’ Those last four words are repeated at intervals throughout the narrative. They are, as it were, the keynote of the book; Wade returns to them many times to anchor his observations — and some speculations — on the history and development of human societies.” (my emphasis there – h.chick)

henry harpending on science“[T]his is perhaps at the heart of the slander of the so called hbd-crew that circulates. Most of us are really interested, in our hearts, in theory and models. This is the way that most of science works…. You state somewhere that the hbd crew is obsessed with IQ. Seems so, but wait! IQ is literally the only thing that can be reliably measured of a whole constellation of interesting traits. It really does work in the sense of telling one whom to hire or whom to admit to graduate school. You also speak of what we ‘believe’ but the whole fun of science is falsifying hypotheses, not believing them. I would give my eye teeth (if I had them) to come up with something besides IQ to look at.” (my emphasis again – h.chick)

Digging For Gold: Study Says Your Race Determines Your Earwax Scent – h/t hbd bibliography!

Austronesians Out of the Cauldron“…the emergence of Austronesians. Linguistics and archaeology already were rather clear on the pattern of expansion, and when. But now an ancient DNA remain from off the coast of Fujian dated to ~8,000 years ago solidifies in totality the where and when. This is not an argument anymore.” – from razib.

New Diet, Sexual Attraction May Have Spurred Europeans’ Lighter Skin“[A] new study of ancient DNA concludes that European skin color has continued to change over the past 5000 years, suggesting that additional factors, including diet and sexual attraction, may also be at play.” – see also: Natural selection has altered the appearance of Europeans over the past 5,000 years.

Did Europeans become white in historic times? – from peter frost.

Pause Is Seen in a Continent’s Peopling“Using a new method for exploring ancient relationships among languages, linguists have found evidence further illuminating the peopling of North America about 14,000 years ago. Their findings follow a recent proposal that the ancestors of Native Americans were marooned for some 15,000 years on a now sunken plain before they reached North America.”

The place of the Armenian language in the Indo-European family“A very interesting talk at the Library of Congress making a good case for a Greek-Phrygian-Armenian clade within the Indo-European family.” – from dienekes.

One Million Brits ‘Descended from Vikings” DNA Study Claims“Around one million Britons, or one in 33 men across the UK, can claim direct descent from Vikings, according to a new DNA study. Men from the far north of Scotland were most likely to provide a direct match with almost a third (29.2%) of the men from the Shetland Islands testing positive for Viking blood.” – h/t ed west!

Genetic Architectures“The point is that the genetic architecture of a quantitative trait does not have to be the same in different populations of the same species. For example, I have the impression that height is not as highly polygenic in Pygmies as it is most other human populations. There’s a particular region on chromosome 3 that seems to influence height- you don’t see such a concentration in Europeans.” – another from greg cochran.

Molecular genetic contributions to socioeconomic status and intelligence – h/t billaire! who tweeted: “21% of the var. in education level, 18% of SES, 29% of cognitive ability explained by COMMON SNPs in Scottish sample.”

Study finds genetic link between height and IQ“A team of researchers at Edinburgh University in Scotland has found a correlation between genes associated with height and those associated with intelligence. In their paper published in the journal Behavior Genetics, the group describes how they studied the DNA of 6,815 unrelated people and discovered what they describe as a direct correlation between height and intelligence—taller people are smarter, they say.”

Want Success? Choose the Right Parents“Gregory Clark’s startling new book, ‘The Son Also Rises,’ asks you to rethink everything you thought you knew about social mobility. His research, if it’s correct, isn’t good news. It says that socio-economic status is mostly a matter of nature not nurture, and suggests that trying to help the disadvantaged move up won’t make much difference.” – h/t alice teller! – see also: Social mobility: Have and have not“Mr Clark follows his logic to an unexpectedly egalitarian end. Redistribution is sensible, he argues, not in order to boost mobility but because mobility is intractably low. The cream will rise regardless, and so paying extraordinary salaries to capable workers is unnecessary. If high rates of mobility are used to excuse or justify inequality, he suggests, then the reality of low mobility implies something quite different: t hat great inequality serves little purpose and redistributing income from the rich to the poor might raise overall welfare at little economic cost. This makes for uncomfortable reading for those of all ideological persuasions.”

Why HBD“As I have tired to explain in my earlier post, Environmental Hereditarianism, the behavioral and physical traits of people are environmentally context-dependent. The broad environmental context regulates the expression of the genes. There is *not* a dichotomy between genes and ‘environment’. Nor could there be one – we are always ‘with’ both. The broad environment includes geography, climate, technology, and prevailing social landscape (otherwise known as ‘culture’). When the social-technological-geographic landscape changes, you can have broad behavioral change all without genetic change. This explains secular changes that occur too quickly to be a result of evolution, such as the sexual revolution, the modern rise in irreligiosity, the increase in the obesity rate, etc.” – from jayman.

Key connection“Biologists zero in on role of plasticity in evolution. For more than a century, scientists have suggested that the best way to settle the debate about how phenotypic plasticity — the way an organism changes in response to environment — may be connected to evolution would be to identify a single mechanism that controls both. Harvard researchers say they have discovered just such a mechanism in insulin signaling in fruit flies. Cassandra Extavour, an associate professor of organismic and evolutionary biology, and grad student Delbert André Green II were able to show that a single molecular pathway plays a role in both heritable changes in the flies’ number of ovarioles — egg-producing compartments in the ovaries — and in how they react to their environments by shutting down some ovarioles. The study is described in a paper published this month in the Proceedings of the Royal Society B. ‘This is the first example, to my knowledge, that shows this link — between heritability and plasticity — being controlled by the same mechanism,’ Extavour said. ‘What we’ve done with this paper is show that an important trait that controls how many offspring a fruit fly will have exhibits both heritable variation and phenotypic plasticity, and that both are controlled by insulin signaling.’” – h/t steven pinker!

Morality and the Lament of the Liberal Atheists“Moral relativism is the ground state of living things. It doesn’t work for a social species like ours. If every one of us tried to monopolize all the available resources within his grasp at the cost of everyone else, the chances that any given individual would survive and reproduce would be drastically reduced. Therefore, morality. It exists because, from an evolutionary perspective, it works. It will continue to function just as it always has, even if 100,000 philosophers shout at the top of their lungs that it’s irrational. Of course it is, but it doesn’t matter. We will continue to perceive the good and evil that seem so real to our imaginations as absolutes. It is our nature to do so….” – from helian

Hypothesis on Why Northwest Europe Began Outbreeding“It could just be coincidence that the outbreeding areas that coincide with other positive hajnal line traits were also lands conquered by men from tribes with the traditions of Germanic kingship. These kings were illiterate barbarians seeking legitimacy and thinking long term at the security of their line ruling…. This is a hypothesis, but the position these rulers were in was one of new conquerors in foreign lands. They needed to create and encourage loyalty in the natives as well as find a way to secure their individual line as king in a manner that was different from what their people, the conquerors, were accustomed to. The Church, an institution eager for power in a new area as well, offered an opportunity to import a political infrastructure and change the social make up of their new lands. Even moreso in England than the rest of core Europe, the Church and the elite’s motivations and goals overlapped perfectly. Christianity was new to them and new to the Britains, but as conversions mounted, it was a shared trait amongst them all. That shared identity was the warrior-chiefs’ way to have rule and kingship legitimized. That shared identity made the natives and newcomers men of Kent or East Anglia, later England, and not of the clan.” – good stuff from son of brock landers!

Do Women’s Mate Preferences Change Across the Ovulatory Cycle? A Meta-Analytic Review – answer: yes. – see also: Intersexual conflict across women’s ovulatory cycle“Results indicate that (a) men are particularly self-assertive toward partners when their partners are fertile; (b) similarly, women are especially self-assertive toward partners when they are fertile; (c) women report engaging in more behaviors that resist male vigilance and mate-guarding when they are fertile, especially in ways that are unobservable to male partners; (d) these effects are especially strong when women themselves report greater attraction to men other than partners when they are fertile, compared to the luteal phase.” – h/t robert burriss!

Study finds less cooperation among women than among men where hierarchy is involved“‘When I studied young children, I noticed that boys were typically interacting in groups, and girls tended to focus on one-on-one relationships,’ said Benenson, the study’s lead author, who explored similar questions in her book Warriors and Worriers. ‘There is even evidence that these differences exist in six-month-olds – but you can see it with the naked eye by about five or six years old, where boys form these large, loose groups, and girls tend to pair off into more intense, close friendships.’ What makes those differences particularly provocative, Benenson said, is that chimpanzees organize their relationships in nearly identical ways. ‘Chimpanzee males usually have another individual they’re very close with, and they may constantly battle for dominance, but they also have a larger, loose group of allies,’ Benenson said. ‘When it comes to defeating other groups, everybody bands together. I would argue that females don’t have that biological inclination, and they don’t have the practice.’”

Personality Traits and Body Mass Index in a Korean Population“Compared with the normal weight groups, overweight and obese men scored higher on openness to experience and lower on conscientiousness. Overweight and obese women scored lower on neuroticism and openness to experience and higher on agreeableness. Extraversion was positively associated with BMI in men (β = 0.032, P<0.05). BMI and waist circumference were significantly increased in individuals who were less dutiful. In women, neuroticism was inversely associated with BMI (β = −0.026, P<0.05). Openness to experience was negatively, and agreeableness was positively, associated with BMI (openness to experience: β = −0.072, agreeableness β = 0.068) and waist circumference (openness to experience: β = −0.202, agreeableness: β = 0.227) (P<0.05).”

The Costume of Shangri-La: Thoughts on White Privilege, Cultural Appropriation, and Anti-Asian Racism – it’s worth quoting the whole abstract: “This piece poses cultural appropriation as an undertheorized aspect of white privilege in White Privilege Studies. By way of narrative exploration, it asserts that a paucity of scholarship on Orientalism and anti-Asian racism has created a gap in White Privilege Studies that curbs its radical transformative potential. It argues for the value of a structural and historically focused lens for understanding the issue of cultural appropriation, and extends questions of culture and race relations beyond the borders of the United States. It also explores the complex ways that interracial and transnational relationships can influence white racial identity, and illustrates the disruptive potential that queer interracial relationships can offer to dominant historical patterns of white behavior.” – (~_^) h/t ben southwood!

DNA USA*“[A]bout about 4 percent of whites have at least 1 percent or more African ancestry. Although it is a relatively small percentage, the percentage indicates that an individual with at least 1 percent African ancestry had an African ancestor within the last six generations, or in the last 200 years. This data also suggests that individuals with mixed parentage at some point were absorbed into the white population. Looking a little more deeply into the data, Kasia also found that the percentage of whites with hidden African ancestry differed significantly from state-to-state. Southern states with the highest African American populations, tended to have the highest percentages of hidden African ancestry…. Previous published studies estimate that on average African Americans had about 82 percent African ancestry and about 18 percent European ancestry. But in self-identified African Americans in 23andMe’s database, Kasia found the average amount of African ancestry was closer to 73 percent. Kasia found significant differences in state-to-state comparisons. African Americans in the northern and western states have more mixed ancestry than those in the southern states…. On average Latinos had about 70 percent European ancestry, 14 percent Native American ancestry and 6 percent African ancestry. The remaining ancestry is difficult to assign because the DNA is either shared by a number of different populations around the world, or because it’s from understudied populations, such as Native Americans.” – from 23andMe.

Common Variants in the CDH7 Gene are Associated with Major Depressive Disorder in the Han Chinese Population“Recent genome-wide association study also demonstrated that CDH7 was significant associated with bipolar disorder…. Our results support CDH7 to be a risk factor of MDD in the Han Chinese population. However, further studies with more markers and independent samples were suggested to validate our findings.”

Humans May Have Been Stuck on Bering Strait for 10,000 Years“In the new Perspectives article, published today (Feb. 27) in the journal Science, the researchers compile existing data to support the idea, known as the Beringia standstill hypothesis. Among that evidence is genetic data showing that founding populations of Native Americans diverged from their Asian ancestors more than 25,000 years ago. In addition, land in the region of the Bering Strait teemed with grasses to support big game (for food) and woody shrubs to burn in the cold climate, supporting a hard-scrabble existence for ancient people.” – razib is skeptical.

Was skin cancer a selective force for black pigmentation in early hominin evolution?“[D]ata on age-associated cancer incidence and lethality in albinos living at low latitudes in both Africa and Central America support the contention that skin cancer could have provided a potent selective force for the emergence of black skin in early hominins.”

Neanderthal Introgression at Chromosome 3p21.31 Was Under Positive Natural Selection in East Asians“Studies of the Neanderthal and Denisovan genomes demonstrate archaic hominin introgression in Eurasians. Here, we present evidence of Neanderthal introgression within the chromosome 3p21.31 region, occurring with a high frequency in East Asians (ranging from 49.4% to 66.5%) and at a low frequency in Europeans. We also detected a signal of strong positive selection in this region only in East Asians…. [S]uggestive evidence supports latitude-dependent selection, implicating a role of ultraviolet-B.”

Neanderthals challenge the origins of speech“Neanderthals, may well have spoken in languages not dissimilar to the ones we use today…. [I]n terms of mechanical behaviour, the Neanderthal hyoid was basically indistinguishable from our own, strongly suggesting that this key part of the vocal tract was used in the same way. ‘From this research, we can conclude that it’s likely that the origins of speech and language are far, far older than once thought.’” – h/t billare (who is 0.1% neanderthal)!

The man who destroyed America’s ego“How a rebel psychologist challenged one of the 20th century’s biggest—and most dangerous—ideas…. Among the most egregious errors they discovered were those in the papers that focused on academic performance. A correlation had been repeatedly found between high self-esteem and good grades. So, the logic went, if you boosted self-esteem you’d also boost grades. But the authors had made one of the most elementary mistakes in science. ‘When they tracked people over time,’ says Baumeister, ‘the grades came first, and then the self-esteem. High self-esteem was a *result* of good grades, not a cause.’” – h/t matthew wygant!

Genetic Influences on Political Ideologies: Twin Analyses of 19 Measures of Political Ideologies from Five Democracies and Genome-Wide Findings from Three Populations“Here we present results from original analyses of a combined sample of over 12,000 twins pairs, ascertained from nine different studies conducted in five democracies, sampled over the course of four decades. We provide evidence that genetic factors play a role in the formation of political ideology, regardless of how ideology is measured, the era, or the population sampled…. We then present results from one of the first genome-wide association studies on political ideology using data from three samples: a 1990 Australian sample involving 6,894 individuals from 3,516 families; a 2008 Australian sample of 1,160 related individuals from 635 families and a 2010 Swedish sample involving 3,334 individuals from 2,607 families. No polymorphisms reached genome-wide significance in the meta-analysis. The combined evidence suggests that political ideology constitutes a fundamental aspect of one’s genetically informed psychological disposition, but as Fisher proposed long ago, genetic influences on complex traits will be composed of thousands of markers of very small effects and it will require extremely large samples to have enough power in order to identify specific polymorphisms related to complex social traits.”

This pattern of Neolithization contrasts markedly to that occurring contemporaneously in the Baltic, suggesting that geographically distinct ecological and cultural influences dictated the evolution of subsistence practices at this critical phase of European prehistory.”

The booms and busts of Neolithic Europe (and their potential impact on our DNA)“most of the interactions between the genetically Near Eastern-like Neolithic farmers and indigenous European hunter-gatherers, including mixing, in all likelihood took place on the peripheries of the farming societies. If so, then perhaps every time there was a bust, it was the relatively more admixed, or even more hunter-gatherer-like, farmer groups from the peripheries that took advantage of the situation and moved in to grab some land in the depopulated regions? In other words, this might have been the process which led to the well-documented reemergence of hunter-gatherer-derived ancestry in the heart of Europe after the early Neolithic.” – @eurogenes.

Males and females differ in specific brain structures“Reviewing over 20 years of neuroscience research into sex differences in brain structure, researchers have conducted the first meta-analysis of the evidence. The team performed a quantitative review of the brain imaging literature testing overall sex differences in total and regional brain volumes. They found that males on average have larger total brain volumes than women (by 8 to 13 percent). Looking more closely, the researchers found differences in volume between the sexes were located in several regions. These included parts of the limbic system, and the language system.”

(note: comments do not require an email. bili apes!)

remember avi tuschman‘s Our Political Nature: The Evolutionary Origins of What Divides Us that i posted about a couple of months ago? and remember how i said that, in large part, he based his theory on what causes the differences between liberals and conservatives on results from what’s known as right-wing authoritarianism (rwa) studies, while at the same time he failed to take into account studies on left-wing authoritarianism?

in case you don’t remember, i said in that previous post:

“i’m sorry, but i can’t help but think that authoritarianism — including personality types that favor authoritarianism — also occurs on the left. a ten-second google search shows me that left-wing authoritarianism has both been researched and found to exist — something which tuschman, unfortunately, doesn’t mention in the book.”

the first two papers i found on left-wing authoritarianism were: The Presence of Left-Wing Authoritarianism in Western Europe and Its Relationship with Conservative Ideology and Left-wing authoritarianism is not a myth, but a worrisome reality. Evidence from 13 Eastern European countries. (more about both of them in the previous post.)

avi responded [my emphasis]:

“The three components of RWA that Altemeyer came up with (including submission and aggression) are NOT the same ones that I use in my analysis, although I did mention his thinking in one place in Ch. 4 where I describe how he developed the test. My own breakdown of the content on his test (shown in the chart above, without the words ‘submission’ or ‘aggression’) is a fresh analysis, and the clusters I’ve described are much more in-line with the underlying statistical factors that emerged from a meta-analysis of 88 studies on multiple political-orientation tests given around the world (including RWA).”

in the book, avi suggests that the political sentiments measured by the right-wing authoritarianism test can be broken down into three broad categories which he defines, and how you feel about the issues related to these categories predicts whether you are liberal or conservative. his three categories (which i described in the previous post) are:

“- Tribalism. Tribalism breaks down into ethnocentrism (vs. the opposite force, xenophilia, which means an attraction to other groups), religiosity (vs. secularism), and different levels of tolerance toward nonreproductive sexuality.

“- Tolerance of Inequality. There are two opposing moral worldviews toward inequality; one is based on the principle of egalitarianism, and the other is based on hierarchy.

“- Perceptions of Human Nature. Some people see human nature as more cooperative, while others see it as more competitive.”

and according to avi, as he claimed in the comment i quoted above, these three categories of his are “in-line” with this meta-analysis of eighty-eight studies conducted “around the world”. here’s what he says about that meta-analysis in the book [from chapter 5 - links and emphases added by me]:

“This breakdown of political ideology coincides very well with independent research conducted by a multidisciplinary team from Stanford University, UC Berkeley, and the University of Maryland, College Park. These professors carried out a meta-analysis of studies on political orientation in North America, Europe, the Middle East, Africa, and New Zealand. The eighty-eight studies they evaluated covered nearly twenty-three thousand individuals who took various types of political tests between 1958 and 2002. These tests included the F-scale, RWA, several other political-conservatism scales, economic-conservatism scales, self-reported ideological positions, issue opinions, and voting records.

“After analyzing all of the data, the team concluded that the ‘two relatively stable, core dimensions that seem to capture the most meaningful and enduring differences between liberal and conservative ideologies’ are: (1) ‘attitudes toward social change versus tradition’ and (2) ‘attitudes toward inequality.’ The analysis showed that, although these two factors are ‘often related to one another,’ they are ‘obviously distinguishable.’

“The meta-study’s first dimension clearly corresponds to the grey cluster (tribalism) in figure 10 [see fig. 10 here - h.chick]. The second dimension [avi's "tolerance of inequality" - h.chick] is the same as the black cluster. What about the white cluster? The debate over the nature of human nature is the ancient subject of political philosophy, which stretches back for millennia. The problem of human nature has also been studied extensively in its own right by political psychologists and evolutionary biologists, who have made valuable discoveries about this core political topic. Moreover, the white cluster overlaps substantially with both the grey and the black clusters; we’ll explore the relationship between them later on.”

ok. so what about this meta-study of these eighty-eight studies conducted around the world? i looked it up:

Political Conservatism as Motivated Social Cognition [pdf]

here’s what the authors of the paper had to say about the eighty-eight studies at which they looked [pg. 14]:

“The data for our review come from 38 journal articles, 1 monograph, 7 chapters from books or annual volumes, and 2 conference papers involving 88 different samples studied between 1958 and 2002. Some of the original data are derived from archival sources, including speeches and interviews given by politicians and opinions and verdicts rendered by judges, whereas others are taken from experimental, field, or survey studies. The total number of research participants and individual cases is 22,818 (see Table 1). The data come from 12 different countries, with 59 of the samples (or 67% of the total) coming from the United States. The remaining samples were studied in England (n=8), New Zealand (4), Australia (3), Poland (3), Sweden (2), Germany (2), Scotland (2), Israel (2), Italy (1), Canada (1), and South Africa (1). Sixty percent of the samples are exclusively composed of college or university student populations, but they account for only 37% of the total number of research participants included in our review. The remaining samples include family members, high school students, student teachers, adult extension students, nonstudent adults, professionals, politicians, judges, political activists, and religious ministers.

jost - table 1

i’m sorry, but THESE ARE ALMOST ALL STUDIES OF W.E.I.R.D. PEOPLE!

apart from israel and poland, all of the countries here are in western europe or are offshoots of western europe (the u.s.a., for example). and the ONE south african study was conducted on white afrikaaner students [pg. 363 in article]. 20,863 out of the 22,818 total number of participants — a full 91% of the total — were from anglo nations (australia, canada, england, new zealand, scotland, united states)!! this meta-study is NOT cross-cultural by any stretch of the imagination. where’s eastern europe (where left-wing authoritarianism has actually been found)? where’s asia (where only 4.3+ billion people live)? where’s latin america?

this is not a meta-analysis of studies conducted “around the world.” this is a meta-analysis of studies conducted on mostly w.e.i.r.d. individuals in the anglo world. which is interesting, but might not tell us much about the rest of the world.

in his comment to the previous post, avi also said:

“There are many places in the book that discuss political extremism on the left. However, the chapter that describes what you’ve referred to as left-wing authoritarianism is Ch. 22, ‘The Altruism That Isn’t: Self-Deception among People and Politicians.’ This chapter explains why extreme left-wing regimes have authoritarian properties. Although when I use the word authoritarian in this context, I’m referring to the structure of left-wing dictatorships. Explaining why these leaders and their regimes violate the egalitarian ideologies that they supposedly espouse is a fascinating question that deserves its own chapter. Leaders (especially dictators) can of course have different interests than followers, even when they ostensibly share an ideology. So measuring tolerance toward inequality in public opinion is different than explaining how dictators behave.

in chapter 22, avi says:

“The Self-Deception of Leaders on the Extreme Left

“Extreme left-wing ideologies typically espouse radical egalitarianism. Yet in practice, Communist governments are famous for their authoritarian dictators. The hierarchy of Communist regimes presents an especially glaring moral hypocrisy. But this hierarchy has a function, which is to serve the self-interest of the dictator; without the protection of hierarchy, the leader wouldn’t be able to remain on *top*.

“In order to maintain popular support, however, left-wing dictators must continue towing a leftist ideology that exalts egalitarianism. Doing so successfully is easier with self-deception. After all, leftist revolutionary leaders would not command so much self-sacrifice from their followers if the followers suspected that their leaders had nefarious plans to sabotage the party’s ideals once in power….”

avi claims that sometimes (oftentimes!) left-wing leaders hijack their movements once they get into power and use their positions at the top for their own ends. sure. that’s pretty obvious. but then he suggests that the leaders need to deceive their followers about things like equality in their new society in order to maintain their position — i.e. the leaders have to pretend that they’re not at the top of any sort of hierarchy, but really just one among equals in society:

“Dictators of the extreme left often try to present a ‘first among equals’ image to obscure the fact that they sit on top of a steep hierarchy. To convince others (and perhaps themselves) that they are merely *primus inter pares*, these leaders are fond of wearing modest clothes. Some wear simple army fatigues. Others, such as Fidel Castro or Hugo Chavez, were also known for donning tracksuits.

“Leftist dictators occasionally use titles to brandish their supposed anti-hierarchical credentials. Colonel Gaddafi’s official title was ‘Brotherly Leader’ of the Great Socialist People’s Libyan Arab Jamahiriya. Rather than taking titles such as president, prime minister, or king, some Communist leaders have assumed the role of ‘chairman’ or ‘secretary,’ suggesting a first-among-equals status on a council.”

but then avi has a hard time explaining this:

“The egalitarian ideal, however, belies a much more hierarchical reality. Indeed, leader worship pervades the cultures of extreme-leftist regimes. Vietnam’s Marxist-Leninist revolutionary Ho Chi Minh is referred to simply as ‘Uncle Hồ.’ Yet an almost god-like personality cult has sprung up around him in the Communist country. Hundreds of people constantly line up to pay homage to his embalmed body at a mausoleum in Hanoi. And an image of Ho Chi Minh appears on every denomination of đồng banknotes circulating in Vietnam.”

the reason he has a hard time explaining this is, i think, because he overlooks the existence of left-wing authoritarianism. the most parsimonious explanation for why many left-wing movements in places like venezuela and vietnam and russia wind up with authoritarian leaders is not (only) that the leaders hijack the movements and subsequently lie to their peoples, but rather because left-wingers in these non-western places are left-wing authoritarians themselves. they want strong leaders — or strong governments, anyway — that will take care of everyone.

but avi hasn’t considered that many left-wingers in some populations might have authoritarian traits, because he’s only looked at studies of authoritarianism in the west — primarily in the anglo world — and, yes, most left wingers in the west don’t seem to have authoritarian traits. only extreme leftists in the west — members of communist/stalinist parties — seem to exhibit such traits (at least according to studies so far). on the other hand, left wingers in eastern europe DO exhibit authoritarian traits — see for example Left-wing authoritarianism is not a myth, but a worrisome reality. Evidence from 13 Eastern European countries.

who knows? researchers might find more left-wing authoritarianism in other parts of the world, too — if they bother looking.

Genomic variation in sharing between siblings“Visscher et al make really nice use of this slight variability in how much of the genome sibs share to learn about how much variation in height within a population is due to genetic variation. They use the fact that sibs who share slightly more of their genome (>0.5) should have more similar heights, than sibs who share less of their genomes (<0.5). This allows them to partition out how much of the resemblance between siblings is due to a shared environment, as opposed to shared genomes…. It also makes me wonder if sibs are actually unconsciously, weakly aware of these subtle genomic differences (through their similarity in a range of traits, including height etc). I could imagine doing a study where siblings (or others) are asked to assess how similar they are/feel, and then assessing whether this is weakly correlated with the fraction of the genome shared. I keep meaning to followup on this idea with some popgen theory to assess how this might play out in modifying kin-selection and altruism between sibs and other relatives." – from graham coop [this guy].

A Living Time Capsule Shows the Human Mark on Evolution“Scientists have revived shrimp-like animals that have been buried at the bottom of the lake for an estimated 700 years. If this estimate holds up to further testing, they are the oldest animals ever resurrected…. The oldest DNA the scientists obtained from the lake dates back to around the time the Vandals were ransacking Rome. The scientists found that one genetic strain of water fleas dominated at the time — and continued to until the late 1800s. As phosphorus [from fertilizers] flooded the lake, a previously rare strain emerged and took over.”

Evolution Hidden in Plain Sight“One of the hallmarks of *Escherichia coli* as a species is that when there’s oxygen around, it can’t feed on a compound called citrate. But one day a flask turned cloudy with an explosion of *E. coli* that were doing just that. The change was so profound that it may mean these bacteria had evolved into a new species.”

SLC24A5 light skin pigmentation allele origin“‘The distributions of C11 and its parental haplotypes make it most likely that these two last steps occurred between the Middle East and the Indian subcontinent, with the A111T mutation occurring after the split between the ancestors of Europeans and East Asians.’” – @dienekes’.

Factor Analysis of Population Allele Frequencies as a Simple, Novel Method of Detecting Signals of Recent Polygenic Selection: The Example of Educational Attainment and IQ [pdf] – “Frequencies of 10 SNPs found to be associated with educational attainment in a recent genome-wide association study were obtained from HapMap, 1000 Genomes and ALFRED. Factor analysis showed that they are strongly statistically associated at the population level, and the resulting factor score was highly related to average population IQ (r=0.90). Moreover, allele frequencies were positively correlated with aggregate measures of educational attainment in the population, average IQ, and with two intelligence increasing alleles that had been identified in different studies.” – h/t elijah! see also jayman.

Ancient hunter-gatherers had rotten teeth“Scientists have long thought that tooth decay only became common in humans about 10,000 years ago, when we began farming – and eating starchy crops that fed sugar-loving bacteria on our teeth. But Isabelle De Groote of the Natural History Museum in London, UK, and her colleagues have found widespread tooth decay in hunter-gatherers that lived several thousand years before the origin of agriculture.”

Is the dark side of parenting genetic?“In a novel finding, Robert Plomin and colleagues suggest that negative aspects of parenting are more heritable than positive aspects. They call this The Dark Side of parenting. The effect is interesting and subtle: it suggests that whilst parents are generally consistent in their handling of their children, some genetically driven characteristics of their children lead them into more negative parenting styles…. In simple terms, even peaceable parents get irritable with difficult children.” – from dr. james thompson.

Lyme bacteria show that evolvability is evolvable“Natural selection favours those with a greater capacity to generate genetic variation.”

50,000 generations of bacteria prove that evolution never stops“[C]omputer models have shown that animals can still experience significant evolutionary changes over time, even in the absence of selectional pressures. Traits like evolvability, or evolutionary potential. Indeed, the Lenski study shows that the same holds true when working with organisms in evolutionary ‘real time.’ The researchers, who performed a comparative analyses of the bacteria after every 500 generations, showed that E. coli will continue to evolve towards increasing replicative efficiency.” – h/t peter turchin! – see also Krazy Kats from greg cochran.

How Our Minds Went Viral“Based on this research, the scientists propose a scenario. Our ancestors millions of years ago were infected with a virus. Eventually it became lodged in our genome. At some point, a mutation moved the virus enhancer next to the PRODH gene. Further mutations allowed it to helped boost the gene’s activity in certain areas of the brain, such as the hippocampus…. Perhaps our minds are partly the way they are today thanks to an infection our ancestors got a few millions of years ago.” – h/t john durant!

Reconstructing the Population Genetic History of the Caribbean“‘We find evidence of two pulses of African migration. The first pulse—which today is reflected by shorter, older ancestry tracts—consists of a genetic component more similar to coastal West African regions involved in early stages of the trans-Atlantic slave trade. The second pulse—reflected by longer, younger tracts—is more similar to present-day West-Central African populations, supporting historical records of later transatlantic deportation. Surprisingly, we also identify a Latino-specific European component that has significantly diverged from its parental Iberian source populations, presumably as a result of small European founder population size. We demonstrate that the ancestral components in admixed genomes can be traced back to distinct sub-continental source populations with far greater resolution than previously thought, even when limited pre-Columbian Caribbean haplotypes have survived.’” – @dienekes’.

The Paradox of Diverse Communities“Their simulations of more than 20 million virtual ‘neighborhoods’ demonstrate a troubling paradox: that community and diversity may be fundamentally incompatible goals…. After 20 million-plus simulations, the authors found that the same basic answer kept coming back: The more diverse or integrated a neighborhood is, the less socially cohesive it becomes, while the more homogenous or segregated it is, the more socially cohesive…. [T]he models demonstrated that it was impossible to simultaneously foster diversity and cohesion ‘in all reasonably likely worlds.’ In fact, the trends are so strong that no effective social policy could combat them, according to Neal. As he put it in a statement, ‘In essence, when it comes to neighborhood desegregation and social cohesion, you can’t have your cake and eat it too.’” – see also original research article: The (In)compatibility of Diversity and Sense of Community [pdf]. – h/t nearly everybody on twitter!
