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.
It made their brown eyes blue… – “A recent report in PNAS shows the inhabitants of the Ukraine and its environs had much darker hair, skin, and eyes back in the Bronze Age and earlier.” – from greg cochran.
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).”

Ed Houben has come to see his daughter for the first time. He talks gently to the six-week-old baby, and little Madita looks up at him. She is, he says, his 98th child.”
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!

Y-chromosome “Adam” was not necessarily human – “From the point of view of population genetics, there is absolutely no reason that the common ancestor of all human Y chromosomes must have existed in an individual that we would identify as ‘human’.”
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].

Genome of longest-living cancer: 11,000-year-old living dog cancer reveals its origin, evolution – “A cancer normally lives and dies with a person, however this is not the case with a sexually transmitted cancer in dogs. In a new study, researchers have described the genome and evolution of this cancer that has continued living within the dog population for the past 11,000 years.”
Why the masculine face? Genetic evidence reveals drawbacks of hyper-masculine features – “[A]round half the variation in both male and female facial masculinity could be attributed to additive genetic variation…. The extensive genetic variation in masculinity makes more plausible the idea that choosing to mate with a masculine man can result in more attractive offspring. But the genes that made a male face more masculine did not make it more attractive. Worse, these same genes made female faces more masculine and thus less attractive. Families that make manly-looking sons tend also to make masculine-looking daughters.”
Casting Out The Devil – “[C]onservatives generally think that liberals are misguided, and live in deep denial of obvious truths about human nature and the way the world actually works (as opposed to the way they think it *ought* to work), liberals view conservatives not just as misguided, but as *morally evil*.” – from malcolm pollack.

‘Rare’ Gene Common in African Descendants, May Contribute to Heart Disease – “Researchers at Weill Cornell Medical College have found that a genetic variation that is linked to increased levels of triglycerides — fats in the blood associated with disorders such as heart disease, type 2 diabetes, obesity and stroke — is far more common than previously believed and disproportionally affects people of African ancestry…. The finding offers a clue as to why Africans and people of African descent have an increased risk of cardiovascular disease and type 2 diabetes compared to many other populations, says the study’s senior author, Dr. Ronald Crystal, chairman of genetic medicine at Weill Cornell. African Americans with the variant had, on average, 52 percent higher triglyceride levels compared with blacks in the study who did not have the variant…. The gene variant the scientists studied is a single point mutation — a replacement of one of DNA segment with another — in the ApoE gene, which carries fats and other molecules through the blood.” – h/t hbd bibliography!
A gene mutation for excessive alcohol drinking found – “UK researchers have discovered a gene that regulates alcohol consumption and when faulty can cause excessive drinking…. [M]ice with a genetic mutation to the gene Gabrb1 overwhelmingly preferred drinking alcohol over water, choosing to consume almost 85% of their daily fluid as drinks containing alcohol…. Dr Quentin Anstee, Consultant Hepatologist at Newcastle University, joint lead author said: ‘It’s amazing to think that a small change in the code for just one gene can have such profound effects on complex behaviours like alcohol consumption.’“ – see also Firewater from greg cochran.
Predicting Human Body Height from DNA – “Predicting tall stature from these 180 DNA variants resulted in an accuracy of 0.75 on a scale from 0.5 (meaning random prediction) to 1.0 (completely accurate prediction). ‘Although the achieved DNA-based prediction accuracy for tall stature is still somewhat lower than we previously established for eye color, hair color and age,’ said Kayser, ‘I expect that upcoming new knowledge on height genetics will further increase the accuracy in predicting tall stature, and eventually the full range of body height, from DNA.'”
Study Connects Dots Between Genes, Human Behavior – “The team studied individuals with a rare disorder known as Williams syndrome. By measuring neural activity in the brain associated with the distinct language skills and facial recognition abilities that are typical of the syndrome, they showed that Williams is due not to a single gene but to distinct subsets of genes, hinting that the syndrome is more complex than originally thought.”
Different Gene Expression in Male, Female Brains May Help Explain Brain Disorder Differences – “UCL scientists have shown that there are widespread differences in how genes, the basic building blocks of the human body, are expressed in men and women’s brains. Based on post-mortem adult human brain and spinal cord samples from over 100 individuals, scientists at the UCL Institute of Neurology were able to study the expression of every gene in 12 brain regions…. They found that the way that the genes are expressed in the brains of men and women were different in all major brain regions and these differences involved 2.5% of all the genes expressed in the brain.” – h/t heartiste!

If an alarm goes off, respond to it. Got a bad feeling? Address it. Something nagging at you? Stop and look into it. Don’t ignore these signals. Don’t rationalize and mentally correct them. Don’t dismiss them without assessing them. Your body is built for survival and one of its hard-wired systems is designed to alert you to danger.” – h/t mr. mangan, esq!

sorry for the delay! the sunday linkfest hasn’t appeared on a wednesday since … gee … the last time it appeared on a wednesday! (*^_^*)
Butterflies show origin of species as an evolutionary process, not a single event – “The evolution of new species might not be as hard as it seems, even when diverging populations remain in contact and continue to produce offspring…. ‘We find that only a small fraction of the genome is markedly different between closely related species, but then much more of the genome — more than you’d expect — shows similar differences between more distantly related species…. That indicates that the genetic changes that are important for causing speciation are tightly clustered early in speciation, but not so later on in the process; the overall pattern of genome divergence starts slow and then skyrockets.'”
Mating advantage for rare males in wild guppy populations – “Negative frequency-dependent selection (NFDS), a form of selection in which genotypes are favoured when they are rare, can potentially maintain such extensive polymorphism, but few experimental studies have confirmed its operation in nature…. Here we use highly replicated experimental manipulations of natural populations to show that males with rare colour patterns have higher reproductive fitness, demonstrating NFDS mediated by sexual selection. Rare males acquired more mates and sired more offspring compared to common males and, as previously reported, had higher rates of survival.” – h/t rob brooks!
Japanese north–south gradient in IQ predicts differences in stature, skin color, income, and homicide rate – “In Japan, there is IQ gradient from north to south. Stature and average income cline is also from north to south. Homicide rates increase from north to south. Fertility rates and suicide rates decrease from north to south. Infant mortality is not correlated with latitude.”
Global patterns of sex-biased migrations in humans – “We found that genetic differentiation between populations was higher for Y chromosome than for the mtDNA at global scales. The migration rate of female might be three times higher than that of male, assuming the effective population size is the same for male and female.” – h/t hbd bibliography!
Shape Differences Between the Faces of Homosexual and Heterosexual Men – “Homosexual men showed relatively wider and shorter faces, smaller and shorter noses, and rather massive and more rounded jaws, resulting in a mosaic of both feminine and masculine features.” – h/t neuroskeptic!
The rule-dependence model explains the commonalities between the Flynn effect and IQ gains via retesting – “[W]e propose that Flynn effect gains are partly a function of the degree to which a test is dependent on rules or heuristics. This means that testees can become better at solving ‘rule-dependent’ problems over time in response to changing environments, which lead to the improvement of lower-order cognitive processes (such as implicit learning and aspects of working memory). These in turn lead to apparent IQ gains that are partially independent of general intelligence. We argue that the Flynn effect is directly analogous to IQ gains via retesting, noting that Raven’s Progressive Matrices is particularly sensitive to both the effects of retesting and the Flynn effect.” – from woodley and armstrong! (^_^) – see also dr. thompson.
Civilizations rise and fall on the quality of their soil – “Great civilisations have fallen because they failed to prevent the degradation of the soils on which they were founded…. This is according to Professor Mary Scholes and Dr Bob Scholes who have published a paper in the journal Science, which describes how the productivity of many lands has been dramatically reduced as a result of soil erosion, accumulation of salinity, and nutrient depletion.”
Bad reporting generates bad arguments – “The Sunday Times gets 3.5 million readers a week. Anything mentioned in it has a chance of influencing public understanding and opinion in Britain. Last week they did a piece on Professor Robert Plomin’s recent book ‘G is for Genes’ which focuses on the genetic contribution to scholastic achievement. The newspaper’s coverage was misleading….” – of course. – from dr. james thompson.
Embryo Selection for Cognitive Enhancement – “We find that embryo selection, on its own, may have significant impacts, but likely not drastic ones, over the next 50 years, though large effects could accumulate over multiple generations. However, there is a complementary technology, stem cell-derived gametes, which has been making rapid progress and which could amplify the impact of embryo selection, enabling very large changes if successfully applied to humans.” – h/t mike anissimov!

The Uncertain Biological Basis of Morality – “[S]ome of our deepest moral intuitions are gut feelings that are with us for no more lofty a reason than that they helped our ancestors protect themselves and spread their genes.” – h/t urho lintinen! – see also: You Can’t Learn About Morality from Brain Scans.
War Before Civilization – from peter turchin.
Cooperation and conflict between women in the family – “Reproductive competition within and between families may have underpinned the biological evolution of fertility patterns (such as menopause) and the cultural evolution of marriage, residence, and inheritance norms (such as late male marriage or primogeniture), which can enhance cooperation and minimize the observed incidence of such conflicts.”
Do human females use indirect aggression as intrasexual competition strategy? [pdf] – yes. (duh.) – h/t michael w. story!
Bone flute discovery indicates 9000 years of Chinese music tradition – “Archaeologists announced the discovery of three ancient flutes made of red-crowned crane bones that may prove that Chinese have been playing music for 9,000 years. The flutes were excavated at an ancient tomb in the site of a Neolithic settlement in Henan Province…. The bone flutes, pictured above, are thought to be the world’s earliest heptatonic musical instruments ever discovered.”
Total Fertility Rate – “Oversimplifying, if your tribe has 60 men and 40 women, if each woman has two kids during her lifetime, when the next generation turns over, your population will have declined from 100 people to 80. Conversely, if your tribe has 40 men and 60 women, and each woman has two kids, your tribe will have grown from 100 to 120. The female sex is the limiting factor when it comes to reproduction, after all.” – from the awesome epigone.
Earlier Onset of Puberty in Girls Linked to Obesity – “[T]he respective ages at the onset of breast development varied by race, body mass index (obesity), and geographic location. Breast development began in white, non-Hispanic girls, at a median age of 9.7 years, earlier than previously reported. Black girls continue to experience breast development earlier than white girls, at a median age of 8.8 years. The median age for Hispanic girls in the study was 9.3 years, and 9.7 years for Asian girls. Body mass index was a stronger predictor of earlier puberty than race or ethnicity.” – h/t hbd bibliography!
What color are Whites? – “In reality, most *Français de souche* act as individuals and have only a weak sense of their collective interest. Collective action is instead wielded by better organized factions, particularly the globalized business community—which lobbies hard to outsource employment to low-wage countries and insource low-wage workers.” – from peter frost.

bonus bonus: There’s a global morality gap — and it’s getting wider – “It is now clear, though not much talked about, that humanity, all 7.1 billion of us, tends to fall into one of two distinct camps. On the one side are those who buy into the whole post-Enlightenment human rights revolution. For them the moral trajectory of the last 300 years is clear: once we were brutal savages; in a few decades, the whole planet will basically be Denmark, ruled by the shades of Mandela and Shami Chakrabarti. And there’s some truth in this trajectory — except for the fact that it only applies to half the planet. The other half resolutely follows a different moral code: might is right, all men were not created equal and there is a right and a wrong form of sexual orientation. You can identify those countries in the dark half of the divide by their attitudes to homosexuality and women; to honour killings, race, disability, mental illness, religious minorities and to crime, torture and punishment, even animal rights and the environment.” – h/t ed west!

Patterns of selection on Neanderthal alleles in modern humans – “‘We identified Neandertal alleles that are at higher frequency than expected under a model of neutral evolution, and identify dozens of genomic locations in Europeans and East Asians at which the Neandertal alleles are the targets of positive selection. Interestingly, there is evidence for more extensive positive selection in East Asian than in European populations.'” – @race/history/evolution notes.
On the antiquity of language: the reinterpretation of Neandertal linguistic capacities and its consequences – “[W]e argue here that recognizably modern language is likely an ancient feature of our genus pre-dating at least the common ancestor of modern humans and Neandertals about half a million years ago.” – via mr. mangan, esq.!

It’s tragic.” – yup. =/ from the awesome epigone.
Ethnic background influences immune response to TB – “Over the thousands of years that humans have been infected with TB, people of different ethnicities have evolved different immune mechanisms for handling the bacteria, a finding that could affect the outcome of planned trials for new TB drugs…. [D]ifferences in the way TB affects the body are also linked to ethnicity. For example, he found that most infections in Europeans are in the lungs, for example, while Asians and Africans get most TB infections in other organs.” – @new scientist. also: Scientists discover ethnic differences in immune response to TB bacterium.

Chinese People May Be at Higher Risk for Stroke Than Caucasians – “[T]he research found a slightly higher overall risk of stroke in Chinese people than in Caucasians, with a range of 205 to 584 strokes per 100,000 Chinese people age 45 to 74, compared to 170 to 335 strokes per 100,000 Caucasian people the same age. Chinese also had a higher risk of intracerebral hemorrhage, a type of stroke due to bleeding into the brain from a ruptured blood vessel, compared to Caucasian people, or 33 percent of all strokes compared to 12 percent of all strokes in community-based studies. Chinese people had a lower average age of stroke onset of 66 to 70 years-old, compared to 72 to 76 years-old for Caucasians.” – via hbd bibliography!
