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.

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.”

Intelligent people are more likely to trust others“Intelligent people are more likely to trust others, while those who score lower on measures of intelligence are less likely to do so, says a new study. Researchers based their finding on an analysis of the General Social Survey, a nationally representative public opinion survey carried out in the United States every one to two years.” – h/t mr. mangan, esq!

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)!

READ THIS (yes, there *will* be a pop quiz on the material later in the week (~_^) )!: Environmental Hereditarianism“[T]here is little evidence linking most ‘measurable’ aspects of the environment to human physical or behavioral traits….

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.”

Your Ancestors, Your Fate“The notion of genetic transmission of ‘social competence’ — some mysterious mix of drive and ability — may unsettle us. But studies of adoption, in some ways the most dramatic of social interventions, support this view. A number of studies of adopted children in the United States and Nordic countries show convincingly that their life chances are more strongly predicted from their biological parents than their adoptive families. In America, for example, the I.Q. of adopted children correlates with their adoptive parents’ when they are young, but the correlation is close to zero by adulthood. There is a low correlation between the incomes and educational attainment of adopted children and those of their adoptive parents. These studies, along with studies of correlations across various types of siblings (identical twins, fraternal twins, half siblings) suggest that genetics is the main carrier of social status.” – from gregory clark. see also The Son Also Rises: Surnames and the History of Social Mobility.

Reductionism! Determinism! Straw-man-ism!” The main problem, it seems to me, is a fundamental misunderstanding of what genetics as a science studies and how it relates to the function of complex systems. The following statements are not contradictory: 1. The function of a complex system emerges from the complex and dynamic interactions between all of the components of the system, in a context- and experience-dependent manner. 2. Variation in single components of the system (or in multiple components) can affect how it functions. Geneticists investigate the second question. Showing that variation in Gene X affects the behaviour or outcome of a system is not the same as saying that Gene X fully determines that behaviour or fully accounts for the entire system. Gene X is just a piece of DNA sitting in a cell somewhere – it doesn’t do anything by itself. But a *difference* in Gene X can account for a *difference* in how the system works. – from kevin mitchell.

The effect of paternal age on offspring intelligence and personality when controlling for paternal trait level [pdf] – “We examined the effect of father’s age at birth on offspring intelligence, head circumference and personality traits. Using the Minnesota Twin Family Study sample we tested paternal age effects while controlling for parents’ trait levels measured with the same precision as offspring’s. From evolutionary genetic considerations we predicted a negative effect of paternal age on offspring intelligence, but not on other traits. Controlling for parental intelligence (IQ) had the effect of turning an initially positive association non-significantly negative. We found paternal age effects on offspring IQ and Multidimensional Personality Questionnaire Absorption, but they were not robustly significant, nor replicable with additional covariates. No other noteworthy effects were found.” – from lars penke.

Reversed hierarchy in the brain for general and specific cognitive abilities: A morphometric analysis“Here, we analyze gray matter with three morphometric indices (volume, cortical surface area, and cortical thickness) at three levels of the intelligence hierarchy (tests, first-order factors, and a higher-order general factor, g)…. The key finding reveals substantial variability in gray matter correlates at the test level, which is substantially reduced for the first-order and the higher-order factors. This supports a reversed hierarchy in the brain with respect to cognitive abilities at different psychometric levels: the greater the generality, the smaller the number of relevant gray matter clusters accounting for individual differences in intelligent performance.” – h/t ben southwood!

Brighter persons have a lower proportion of their abilities accounted for by a common factor, even though the have higher absolute abilities.” – from dr. james thompson.

People believe in free will – at least in part – because they wish to affirm that people who do immoral things could have and should have acted differently’.”

Migration and interaction in a contact zone: mtDNA variation among Bantu-speakers in southern Africa“In this study, we analyze complete mtDNA genome sequences from over 900 Bantu-speaking individuals from Angola, Zambia, Namibia, and Botswana to investigate the demographic processes at play during the last stages of the Bantu expansion. Our results show that most of these Bantu-speaking populations are genetically very homogenous, with no genetic division between speakers of Eastern and Western Bantu languages. Most of the mtDNA diversity in our dataset is due to different degrees of admixture with autochthonous populations.”

Replacement or continuity?“Ancient DNA seems to promise a clearer picture because the only source of uncertainty is the age of the skeletal material. Unfortunately, this new method is more sensitive to uncertainty from another source: natural selection. Late hunter-gatherers and early farmers had to adapt to different environments.

Calcium absorption not the cause of evolution of milk digestion in Europeans“‘The evolution of lactase persistence is one of the best known and most dramatic examples of recent human evolution. One of the ironies of working in this area is that we know it happened but we still don’t fully know why’ says Sverrisdóttir. Lactase persistence is found at highest frequencies in southern Sweden and in Ireland. Given that calcium absorption is not the only reason why this trait evolved so rapidly, Sverrisdóttir and colleagues have proposed another cause: Although most early European farmers would not have been lactase persistent, they would still have been able to consume fermented milk products such as yoghurt and cheese, because fermentation converts much of the lactose into fats. But in famine conditions, such as when crops fail, they are likely to have eaten all the fermented milk foods, leaving only the more high-lactose products. This would have caused the usual lactose intolerance symptoms such as diarrhea. Diarrhea in in healthy people is not usually life-threatening, but in severely malnourished individuals it certainly can be. So famine could have led to episodes of very strong natural selection favoring lactase persistence.”

Human and Helicobacter pylori coevolution shapes the risk of gastric disease“Patients were recruited from two geographically distinct Colombian populations with significantly different incidences of gastric cancer, but virtually identical prevalence of H. pylori infection. All H. pylori isolates contained the genetic signatures of multiple ancestries, with an ancestral African cluster predominating in a low-risk, coastal population and a European cluster in a high-risk, mountain population. The human ancestry of the biopsied individuals also varied with geography, with mostly African ancestry in the coastal region (58%), and mostly Amerindian ancestry in the mountain region (67%). The interaction between the host and pathogen ancestries completely accounted for the difference in the severity of gastric lesions in the two regions of Colombia. In particular, African H. pylori ancestry was relatively benign in humans of African ancestry but was deleterious in individuals with substantial Amerindian ancestry. Thus, coevolution likely modulated disease risk, and the disruption of coevolved human and H. pylori genomes can explain the high incidence of gastric disease in the mountain population.”

Seeing X Chromosomes in a New Light“X-chromosome inactivation, Dr. Nathans’s pictures show, creates a genetic diversity that’s particularly dramatic. Two cells side by side may be using different versions of many different genes. ‘But there is also much larger-scale diversity,’ Dr. Nathans said. In some brains, for example, a mother’s X chromosome was seen dominating the left side, while the father’s dominated the right. Entire organs can be skewed toward one parent. Dr. Nathans and his colleagues found that in some mice, one eye was dominated by the father and the other by the mother. The diversity even extended to the entire mouse. In some animals, almost all the X chromosomes from one parent were shut; in others, the opposite was true.”

Are plants altruistic?“Roots can distinguish self from other, and they know their own kind (species), they can share resources and information about insect attacks and deliver nutrients to trees in need.

Sluggish metabolisms are key to primates’ long lives“[P]rimates expend 50 per cent less energy than other mammals of equivalent mass during an average day. ‘What’s more, he says the difference is not easily explained by differing activity levels: a human would need to run a whole marathon every day to be on an even energetic footing with mammals that aren’t primates….’ The finding offers a completely new way to understand why primates have slower life histories than other mammals of equivalent body size…. Pontzer thinks that the slower metabolism may have evolved to help primates cope with food shortages. For instance, orang-utans suffer frequent famines. ‘Orang-utans experience extended periods of low fruit availability,’ says Vogel. ‘There are months when caloric intake is less than expenditure – and they burn body fat stores.’ A slow metabolism might help them survive.”

Triune origins“With the latest paper, the story on European origins is becoming clearer. Three populations account for European ancestry: the Mesolithic hunter-gatherers of western Europe (dubbed WHG in the paper), early European farmers derived from somewhere in the Mideast (EEF), and a third group more closely related to ancient Siberians (ANE) than any existing population. Those Sibermen also contributed a third of Amerindian ancestry, the rest being similar to modern East Asian populations.” – from greg cochran.

The first industrial revolution“As early modern humans spread farther north, they entered more challenging environments…. Did these new cognitive demands have an evolutionary impact? Did they select for certain mental capacities over others? Piffer (2013) has addressed these questions by seeing how hunter-gatherers differ from farming peoples in alleles at COMT, a gene linked to executive function, working memory, and intelligence…. Northern hunting peoples, however, differ from other hunter-gatherers and resemble more advanced farming populations.” – from peter frost.

‘Out of Africa’ gene mutation in human pigmentation increases predisposition to skin cancer“The V60L mutation is more common in people with light hair and skin tone that, despite being light, tans easily in the summer. This mutation is positive for the climate of the Mediterranean region, as it facilitates the absorption of vitamin D in the winter months, in which the ultraviolet radiation is lower. In the summer months, in which the radiation is greater, the ease to darken the skin pigmentation provides a certain protection. However, the study also revealed that among people with this mutation there is a greater predisposition to skin cancer.” – see also: Simultaneous Purifying Selection on the Ancestral MC1R Allele and Positive Selection on the Melanoma-Risk Allele V60L in South Europeans.

Changes in Thickness and Surface Area of the Human Cortex and Their Relationship with Intelligence“At 10 years of age, more intelligent children have a slightly thinner cortex than children with a lower IQ. This relationship becomes more pronounced with increasing age: with higher IQ, a faster thinning of the cortex is found over time. In the more intelligent young adults, this relationship reverses so that by the age of 42 a thicker cortex is associated with higher intelligence. In contrast, cortical surface is larger in more intelligent children at the age of 10. The cortical surface is still expanding, reaching its maximum area during adolescence. With higher IQ, cortical expansion is completed at a younger age; and once completed, surface area decreases at a higher rate. These findings suggest that intelligence may be more related to the magnitude and timing of changes in brain structure during development than to brain structure per se, and that the cortex is never completed but shows continuing intelligence-dependent development.”

Why do spatial abilities predict mathematical performance?“About a third of the variation in spatial ability at age 12 is explained by genetic factors; a little less than half of the variation in mathematics at this age is genetic. We find no sex differences in the genetic and environmental influences (either in magnitude or type) on mathematical and spatial variation at age 12. The observed overlap between spatial ability and mathematics is substantial (r > .40). Approximately 60% of this overlap is explained by common genetic effects, with 40% of the overlap due to environmental experience.” – h/t DOCTOR stuart ritchie! (^_^)

Dogs’ Closest Wolf Ancestors Went Extinct, Study Suggests” A new genetic analysis of modern dogs and wolves suggests that man’s best friend was domesticated before agriculture. But the origin of this domestication remains stubbornly mysterious. Researchers analyzed the genomes of wolves from three likely sites of domestication (the Middle East, Asia and eastern Europe), and found that modern dogs were not more closely related to any of the three. In fact, it seems that the closest wolf ancestors of today’s dogs may have gone extinct, leaving no wild descendants.” – also: Paedomorphic Facial Expressions Give Dogs a Selective Advantage – woof! – h/t claire lehmann!

Iberian Neolithic farmer DNA“‘The Neolithic Portalón individual is genetically most similar to southern Europeans, similar to a Scandinavian Neolithic farmer and the Tyrolean Iceman. In contrast, the Neolithic Portalón individual displays little affinity to two Mesolithic samples from the near-by area, La Brana, demonstrating a distinct change in population history between 7,000 and 4,000 years ago for the northern Iberian Peninsula.’” – @dienekes’.

Male and female brains wired differently, scans reveal“Maps of neural circuitry show women’s brains are suited to social skills and memory, men’s perception and co-ordination…. Maps of neural circuitry showed that on average women’s brains were highly connected across the left and right hemispheres, in contrast to men’s brains, where the connections were typically stronger between the front and back regions.” – see also Sex differences in the structural connectome of the human brain. – and see also Stop the Presses! from malcolm pollack.

Promiscuity Is Pragmatic“Why women and other female primates seek out multiple partners…. [T]here are two environmental contexts where women commonly choose multiple partners. The first is where women have more material support from their kin or economic independence from men more generally. This may explain why multiple mating is most common among small-scale matrilocal societies (in which women remain in their home village after marriage), such as the partible paternity societies of South America or the Mosuo of China. It may also explain why female infidelity has increased in Western societies as women have gained greater political and economic independence…. The second environmental context Scelza identified is where the sex ratio is female-biased (indicating a scarcity of men) or there is a high level of male unemployment (indicating a scarcity of men who can provide support).” – one for the gameboyz.

Our IQs Are Climbing, But We’re Not Getting Smarter – re. woodley and armstrong paper.

Academic experts criticise Boris Johnson IQ claims“Dr James Thompson, senior lecturer in psychology at University College London, said Boris had been ‘inelegant’ in his choice of words. Thompson, co-author of Cognitive Capitalism, said: ‘What Boris Johnson has done is inelegantly describe things which in fact do seem to be true: intelligence, however you assess it, is predictive. It’s predicative of income, life span and of occupational status. People are different and have different futures and intelligence seems to be an important part of that.’ He said studies showed there seemed to be a correlation between ‘being bright in youth and doing well in life later’. Asked if inequality was inevitable, he said: ‘In one way that is true. There’s two things, one is that some people are brighter than others and can do more complicated work and that more complicated work is generally more valued.’ However, he added that how much people should be paid was a decision for society. Professor Richard Lynn, co-author of IQ and the Wealth of Nations, said that the association between IQ and income was ‘only modest’. ‘That is because some high IQ people go into jobs that don’t have particularly high earnings like university professors, schoolteachers or social workers. Some professions attract very high IQ people but they don’t have very high earnings,’ he said. ‘You could say that the IQ is only one determinant of high earnings, the others are ambition and motivation and the third one is luck.’” – h/t holtz!

Morality and the State“In general, ‘virtuous’ states – those free of corruption, that do not cheat or steal from their citizens, and that are effective in enforcing laws that are perceived as just – are more effective at promoting the common weal than their opposites. Heraclitus’ dictum that ‘character is destiny’ likely applies to states as well as individuals. I personally think that states are far more likely to be ‘virtuous’ in that sense if their powers are carefully circumscribed and limited.”

Investigation reveals black market in China for research paper authoring“The journal Science has uncovered, via investigation, a thriving black market in science paper authoring—people are paying to have their names added to papers that have been written to describe research efforts…. All in all, the investigative team contacted 27 agencies involved in helping researchers get their work published—only five of them refused an offer to pay for adding a name to a research paper.”

Does Nyborg’s study make sense?“One other thing bothers me. So please let me say it. Why must the Danes prove that they deserve to keep their country to themselves? Isn’t that a basic right? They have only one land to call home…unlike the many ‘refugees’ who regularly visit their own homelands. Once the Danes lose majority status in their country, they’ll be like the Copts of Egypt and other minorities in this world. They’ll have to live by their wits, trying to balance off one potential enemy against another.” – hear, hear! – from peter frost.

Migration Hurts the Homeland“The migration that research shows is unambiguously beneficial is the kind in which young people travel to democracies like America for higher education and then go home. Not only do these young people bring back valuable skills directly learned in the classroom; they bring back political and social attitudes that they have assimilated from their classmates. Their skills raise the productivity of the unskilled majority, and their attitudes accelerate democratization…. Many on the left, for their part, don’t like to recognize that we’re taking away fairy godmothers. They prefer to believe that they’re helping poor people flee difficult situations at home. But we might be feeding a vicious circle, in which home gets worse precisely because the fairy godmothers leave. Humanitarians become caught up trying to help individuals, and therefore miss the larger implications: There are poor people, and there are poor societies. An open door for the talented would help Facebook’s bottom line, but not the bottom billion. – h/t michael story!

Deletion of Any Single Gene Provokes Mutations Elsewhere in the Genome“Johns Hopkins researchers report that the deletion of any single gene in yeast cells puts pressure on the organism’s genome to compensate, leading to a mutation in another gene…. ‘The deletion of any given gene usually results in one, or sometimes two, specific genes being “warped” in response….’”

Europeans and South Asians share by descent SLC24A5 light skin allele“‘We date the coalescence of the light skin associated allele at 22–28 KYA. Both our sequence and genome-wide genotype data confirm that this gene has been a target for positive selection among Europeans. However, the latter also shows additional evidence of selection in populations of the Middle East, Central Asia, Pakistan and North India but not in South India.’” – @dienekes’.

The ancestors with no descendants“On the eve of the last ice age, Siberia was home to a people who were related to modern Europeans and Amerindians but not to modern native Siberians. So concludes an analysis of DNA from the remains of a boy who lived 24,000 years ago at Mal’ta near Lake Baikal, Siberia…. [T]he Mal’ta people probably looked very much like native Indians with a more European skull shape, perhaps like the Ainu of northern Japan or the Kennewick humans of North America.”

Political colour is half genetic“New study provides definitive evidence that heritability plays a significant role in the formation of political ideology, regardless of how ideology is measured, the time period or population sampled.” – @ScienceNordic.com – the photo caption is pretty funny/telling: “Imagine if scientists could identify the ‘liberal’ genes and genetically modify babies so that they all voted liberal when they grow up? Brave new world?” (and the first comment is priceless!) – h/t ray sawhill!

It’s not just conservatives that support discrimination against their ideological foes“‘Discrimination by liberals has received scant attention in the literature, despite this being a prevalent concern in conservative rhetoric. By only examining conservative biases, social scientists fail to fully explore political intolerance in America. This research helps fill that gap….’ When opposing groups were seen as violating core values, liberals were just as likely to support discrimination against same-sex marriage opponents, religious fundamentalists, Tea Party protestors, and prolife people as were conservatives against feminists, atheists, leftist protestors, and prochoice people.”

Rich Chinese Couples Turning To American Surrogates For Easier Immigration And ‘Designer Babies’“Another factor that has some Chinese couples choosing American surrogates is a desire for ‘designer babies.’ While most couples still use their own eggs and sperm, making the child biologically theirs, Reuters reports that more and more people are open to egg donation, to get what some clients believe are smarter and better-looking children. ‘Lots of clients that are Chinese do use tall, blond donors,’ Jennifer Garcia, who works at Extraordinary Conception in California, where 40 percent of clients are Chinese, said in the report.” – h/t mark krikorian!
