Mexican skeleton gives clue to American ancestry – “Naia’s mitochondrial DNA reveals genetic signatures in common with modern Native Americans, despite her very different skull shape. ‘You can never exclude that Native Americans have more than one group of ancestors,’ says Chatters. But his team’s data, he points out, are consistent with the idea that Native Americans evolved from Siberian ancestors…. The new DNA results indicate that the very different skulls of modern Native Americans have evolved on North American soil.” – see also jennifer raff.
Ancient faeces reveal origins of Puerto Rican natives – “DNA isolated from 1,600-year-old fossilized stools suggests migration from the Andes.”
An excess of X-chromosomal diversity in Africans – “‘Results show that X/A diversity is similar within each continental group but notably lower in European (EUR) and East Asian (ASN) populations than in African (AFR) populations.'” – @dienekes’.
Religiosity is negatively associated with later-life intelligence, but not with age-related cognitive decline – from stuart ritchie et al. – “Religious belief was negatively associated with intelligence in old age. Neither religious belief nor attendance was related to cognitive decline.”
The relationship between Microcephalin, ASPM and intelligence: A reconsideration – “At the population-level IQ and Microcephalin correlate significantly (.790 and .847). Microcephalin significantly predicts population differences in IQ. Microcephalin significantly predicts infectious disease burden. Vice versa in the case of Microcephalin. Microcephalin increased disease-resistance allowing access to new cognitive niches.” – from woodley et al. – h/t lars penke!

Molecular genetic contributions to socioeconomic status and intelligence – “21% of the variation in education, 18% of the variation in socioeconomic status, and 29% of the variation in general cognitive ability was explained by variation in common SNPs (SEs ~ 5%). The SNP-based genetic correlations of education and socioeconomic status with general intelligence were 0.95 (SE 0.13) and 0.26 (0.16), respectively. There are genetic contributions to intelligence and education with near-complete overlap between common additive SNP effects on these traits (genetic correlation ~ 1). Genetic influences on socioeconomic status are also associated with the genetic foundations of intelligence. The results are also compatible with substantial environmental contributions to socioeconomic status.”
Longevity Gene May Enhance Cognition – “Mice with the KLOTHO gene variant lived longer and were smarter.”
Short men are likely to live longer because they carry the ‘longevity gene’, scientists reveal – short japanese men… “The so-called ‘longevity gene’ FOXO3 has been proven to enhance lifespan in animal tests but has never before been linked to variations in height in humans. A new scientific study, the largest of its kind and involving more than 8,000 aging American-Japanese men in Hawaii, conclusively showed a direct connection between short height and long life. FOXO3, they found, leads to smaller body size during early development and a longer lifespan overall. Short men were also more likely to have lower blood insulin levels and less likely to get cancer.” – h/t eddy elmer!

Amorality of selected countries – “What Jonathan Haidt terms ‘WEIRD’ societies (read the modern West) tend to the least judgmental, followed by East Asia and the more European nations of Latin America, with sub-Saharan African and Muslim countries the most morally righteous (!). Descartes wept.” – from the awesome epigone.
The coerced consensus – “What is going on in academia when demonising and silencing your opponents has become so acceptable? It’s not just climate change. The nature-nurture debate is also policed by zealots, although less so than in the 1970s when any mention of genes and behaviour led to accusations of fascism…. Truly, the old joke is becoming ever more true: what’s the opposite of diversity? University.” – from matt ridley.
Stanford scholar shows Koreans and Americans tackle moral dilemmas using different brain regions – very small sample size, but… “Korean participants showed greater activity in brain regions associated with intuition, approximation and emotions: the putamen, the dorsolateral prefrontal cortex and the postcentral sulcus. Han posits that Korean participants consciously controlled their initial emotional reactions (such as disgust) to reach a decision that protected the largest number of people. In contrast, Americans took longer to ponder dilemmas that involved physically harming particular people. They also relied on brain regions associated with conflict management and, to a lesser degree, novelty: the anterior cingulate cortex and the frontopolar cortex. Han hypothesizes that Americans are exposed to socio-personal conflict more often than Koreans, whose society values social harmony over the expression of individual desires.”

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)
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.

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.”

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.

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!

Flies see the world in slow motion, say scientists – “Flies avoid being swatted in the same way Keanu Reeves dodges flying bullets in The Matrix, by watching time pass slowly, research suggests. The smaller an animal is, and the faster its metabolic rate, the slower time passes for it, scientists found. This means that across a wide range of species, time perception is directly related to size, with animals smaller than us seeing the world in slow motion…. ‘It’s tempting to think that for children time moves more slowly than it does for grown ups, and there is some evidence that it might…. People have shown in humans that flicker fusion frequency is related to a person’s subjective perception of time, and it changes with age. It’s certainly faster in children.’“ – mind. blown.
Poverty Can Trump a Winning Hand of Genes – “When psychologists first started studying twins, they found identical twins much more likely to have similar IQs than fraternal ones. They concluded that IQ was highly “heritable”—that is, due to genetic differences. But those were all high SES twins. Erik Turkheimer of the University of Virginia and his colleagues discovered that the picture was very different for poor, low-SES twins. For these children, there was very little difference between identical and fraternal twins: IQ was hardly heritable at all…. Richer children have similarly good educational opportunities, so genetic differences among them become more apparent…. But for poor children, haphazard differences in educational opportunity swamp genetic differences.”

Redneck Psychiatrists – “Schizophrenia is more common in men than women – about 1.4 to 1. It’s more common in the lowest SES groups, although that may be downward drift. Schizophrenia is considerably more common among people of African ancestry…. Schizophrenia seems to be more common among people that grew up in cities – about twice as common.” – from greg cochran.
Painful and extreme rituals enhance social cohesion and charity – “The study of 86 males in Mauritius found both observers and performers of the Kavadi were more charitable than those who only participated in the collective prayers. The researchers also found that higher levels of pain were positively associated with larger donations and a more inclusive self-identity.”
Why parents think your partner isn’t good enough – “[P]arents tend to give more resources to children whose partners provide less support, and that this leads to a conflict over mate choice…. ‘Parents are equally related to all of their children, whereas children value themselves more than their siblings — so each child wants to get more than their fair share of parental resources.’ This means that the children are willing to settle for a mate who is less caring than their parents would ideally like.”
The Social Life of Genes – “Your DNA is not a blueprint. Day by day, week by week, your genes are in a conversation with your surroundings.

The team believes this is due to multiple large migrations throughout Chinese history.”
