Europeans drawn from three ancient “tribes”“The modern European gene pool was formed when three ancient populations mixed within the last 7,000 years, Nature journal reports. Blue-eyed, swarthy hunters mingled with brown-eyed, pale skinned farmers as the latter swept into Europe from the Near East. But another, mysterious population with Siberian affinities also contributed to the genetic landscape of the continent.” – see also: Before Slavery“From what I can see so far, it looks as the invaders killed all the LBK-descended farmers in northern Europe, or nearly so. The locals had had long trapezoidal houses clustered in small villages: the Corded Ware culture has almost no buildings at all, and a lot less agriculture. They didn’t make the EEF guys serfs and get a cut of their grain – the villages disappeared. They didn’t tax them, but then money and bureaucracy hadn’t been invented yet. Same for slavery: hadn’t been invented, probably. Judging from the mtDNA patterns, they didn’t even grab many of the nubile women. The genetic mix changes little as you move across the north European plain: if the invaders were picking up local genes as they rolled along, it should have. We used to call Corded Ware the Battle-Axe culture, but that’s too accurate for comfort.” – from greg cochran.

They weren’t wimps: how modern humans, like Neanderthals, braved the northern cold“Recent finds at Willendorf in Austria reveal that modern humans were living in cool steppe-like conditions some 43,500 years ago – and that their presence overlapped with that of Neanderthals for far longer than we thought.” – h/t mr. robert ford!

Stone Age groups made similar toolmaking breakthroughs“Different palaeolithic populations around the world might have developed a crucial toolmaking skill independently. This conclusion, based on the analysis of hundreds of artefacts from a recently excavated archaeological site in Armenia, weakens a long-held theory that Stone Age people in Eurasia learnt sophisticated techniques from migrating African tribes. The work is published in Science.”

Human paternal and maternal demographic histories: insights from high-resolution Y chromosome and mtDNA sequences“Comparisons of maternally-inherited mitochondrial DNA (mtDNA) and paternally-inherited non-recombining Y chromosome (NRY) variation have provided important insights into the impact of sex-biased processes (such as migration, residence pattern, and so on) on human genetic variation…. Our results confirm the controversial assertion that genetic differences between human populations on a global scale are bigger for the NRY than for mtDNA, although the differences are not as large as previously suggested. More importantly, we find substantial regional variation in patterns of mtDNA *versus* NRY variation.” – h/t juan fernández lópez! – see also: New analysis of human genetic history reveals female dominance – (heh. that was a nice twist on the story!

Admixture in Latin America: Geographic Structure, Phenotypic Diversity and Self-Perception of Ancestry Based on 7,342 Individuals“We estimated individual ancestry proportions in a sample of 7,342 subjects ascertained in five countries (Brazil, Chile, Colombia, México and Perú). These individuals were also characterized for a range of physical appearance traits and for self-perception of ancestry. The geographic distribution of admixture proportions in this sample reveals extensive population structure, illustrating the continuing impact of demographic history on the genetic diversity of Latin America. Significant ancestry effects were detected for most phenotypes studied. However, ancestry generally explains only a modest proportion of total phenotypic variation. Genetically estimated and self-perceived ancestry correlate significantly, but certain physical attributes have a strong impact on self-perception and bias self-perception of ancestry relative to genetically estimated ancestry.” – see also razib: The Phenotypic and the Genotypic.

Ashkenazi Jewish population has distinctive, yet similar genomes“Post-population bottleneck, descendants of Eastern European Jews are all 30th-ish cousins…. Compared to genomes of modern Europeans—in this case, the genomes of 26 Flemish people—the Ashkenazi genomes have 47 percent more novel DNA differences per genome. These DNA variants, while novel, are population specific; sequence sharing, where two individuals have a set of the same variants, is eight percent more abundant among the Ashkenazi Jews than it is between the two populations or even among the Flemish genomes.” – h/t billare!

The hereditarian hypothesis almost certainly true“Surely, there are huge benefits to being the first author to publish a study that almost conclusively disproves the genetic model for AA’s. Researchers with access to the data have a strong incitement to publish such a study. If the data supports the view, they have all the necessary means too. Since they haven’t published it, we can hence infer that the data does not support the politically favorable non-genetic conclusion, but instead the genetic model.” – also from emil kirkegaard.

Human preferences for sexually dimorphic faces may be evolutionarily novel [pdf] – “A large literature proposes that preferences for exaggerated sex typicality in human faces (masculinity/femininity) reflect a long evolutionary history of sexual and social selection. This proposal implies that dimorphism was important to judgments of attractiveness and personality in ancestral environments. It is difficult to evaluate, however, because most available data come from large-scale, industrialized, urban populations. Here, we report the results for 12 populations with very diverse levels of economic development. Surprisingly, preferences for exaggerated sex-specific traits are only found in the novel, highly developed environments. Similarly, perceptions that masculine males look aggressive increase strongly with development and, specifically, urbanization.” – h/t jayman!

Do your genes skew how you taste alcohol?“A new study shows that how people perceive and taste alcohol varies as a result of genetics. The scientists focused on three chemosensory genes—two bitter-taste receptor genes known as TAS2R13 and TAS2R38 and a burn receptor gene, TRPV1. The research is the first to consider whether variation in the burn receptor gene might influence alcohol sensations, which has not previously been linked to alcohol consumption.” – alcohol tastes gooooood!

Violent Video Games and Real-World Violence: Rhetoric Versus Data“Contrary to the claims that violent video games are linked to aggressive assaults and homicides, no evidence was found to suggest that this medium was positively related to real-world violence in the United States. Unexpectedly, many of the results were suggestive of a decrease in violent crime in response to violent video games. Possible explanations for these unforeseen findings are discussed and researchers are cautioned about generalizing the results from laboratory and correlational studies to severe forms of violent behavior.” – h/t mugwump! who tweeted some of the tables here, here, and here.

Paradox of nationalism“Nationalism as we know it arose in modern times in Europe. Other countries outside Europe just don’t seem to have the same thing, although there are exceptions, such as Japan, or maybe Turkey. And in fact, nationalism was at one time considered a part of liberalism – which is another European invention…. Other countries that don’t have the same history as Europe seem unlikely to develop that kind of nationalism. Think of Iraq, Syria, most African countries, even China: they are more given to clannishness than patriotism.” – from mr. mangan, esq.

Confusion Over the Biological Reality of the Human Races“[O]ne can see clearly why Wade’s argument is not racist: at the core of his argument is his claim that the tribalism of racial ethnocentrism belongs to an ancient stage of human evolution that has to be overcome to move into modern states and inclusive institutions (see Wade, 136, 173-82, 196-97).” – larry arnhart on A Troublesome Inheritance.

The Woman’s Heart Attack“[M]en more typically have ‘crushing’ pain; women, nausea. That women are likelier to have early warning signs, such as unaccustomed fatigue or insomnia (unaccustomed: That’s the key word here). That we are likelier — this spooked me and kept me, for months, glued to calendars — to die within a year of a heart attack. That our symptoms can be so varied and nuanced that we feel no fear, seek no help, and possibly die — which may be why, although more men have heart attacks, a greater percentage of women die of them.”

The Evolution of Culturally-Variable Sex Differences: Men and Women Are Not Always Different, but When They Are…It Appears *Not* to Result from Patriarchy or Sex Role Socialization“[E]vidence is marshaled across 21 data sources that directly challenge this foundational assumption of social role theory. Empirically, sex differences in most psychological traits — in personality, sexuality, attitudes, emotions, behaviors, and cognitive abilities — are conspicuously *larger* in cultures with more egalitarian sex role socialization and greater sociopolitical gender equity. Even sex differences in many physical traits such as height, obesity, and blood pressure are larger in cultures with more egalitarian sex role socialization and greater sociopolitical gender equity.”

School Performance After Preterm Birth“An increased risk of poor school performance for children born preterm has been shown in many studies, but whether this increase is attributable to preterm birth per se or to other factors associated with preterm birth has not been resolved…. Preterm birth was strongly and negatively correlated with school performance. The distribution of school grades for children born at 31-33 weeks was on average 3.85 (95% confidence interval = -4.36 to -3.35) centiles lower than for children born at 40 weeks. For births at 22-24 weeks, the corresponding figure was -23.15 (-30.32 to -15.97). When taking confounders into account, the association remained. When restricting the analysis to siblings, however, the association between school performance and preterm birth after week 30 vanished completely, whereas it remained, less pronounced, for preterm birth before 30 weeks of gestation. Our study suggests that the association between school performance and preterm birth after 30 gestational weeks is attributable to factors other than preterm birth per se.”

Can the Game of Thrones option save the UK?“The situation now resembles the Union of Crowns from 1603-1707 when Scotland had its own parliament but was still under the king in Westminster, and Cameron is behaving like Charles I: making promises to his northern kingdom that affect the southern one, without regards to how the southerners feel. Just as in 1640, the greatest protests are coming from the east of England, once the stronghold of Puritanism and the parliamentary rebels and now the Ukip heartland.” – from ed west.

God, Darwin and My College Biology Class“[A] third consequence of evolutionary insights: a powerful critique of theodicy, the scholarly effort to reconcile belief in an omnipresent, omni-benevolent God with the fact of unmerited suffering. Theological answers range from claiming that suffering provides the option of free will to announcing (as in the Book of Job) that God is so great and we so insignificant that we have no right to ask. But just a smidgen of biological insight makes it clear that, although the natural world can be marvelous, it is also filled with ethical horrors: predation, parasitism, fratricide, infanticide, disease, pain, old age and death — and that suffering (like joy) is built into the nature of things. The more we know of evolution, the more unavoidable is the conclusion that living things, including human beings, are produced by a natural, totally amoral process, with no indication of a benevolent, controlling creator.” – david barash, pessimist(?).

reparations

whaddya suppose the statute of limitations is on reparations for slavery?

i mean, there was plenty of slavery back in medieval europe (pgs. 43-65 and 88-113), and given that my entire extended family are a bunch of lovable lugs, i’m pretty sure many of my ancestors were probably on the receiving end of all that enslavement, so where do i apply?

come to think of it — african-americans ought to think about demanding reparations from some african nations. and i don’t mean because some of the people from those countries, who are all now long gone, were involved in the transatlantic slave trade, but rather because the ancestors of many african-americans were probably slaves back IN africa. somebody oughta sue…somebody!

Skull Fossil Suggests Simpler Human Lineage“Early, diverse fossils — those currently recognized as coming from distinct species like Homo habilis, Homo erectus and others — may actually represent variation among members of a single, evolving lineage. In other words, just as people look different from one another today, so did early hominids look different from one another, and the dissimilarity of the bones they left behind may have fooled scientists into thinking they came from different species.” see also: Skull of Homo erectus throws story of human evolution into disarray @the guardian. see also john hawks: The new skull from Dmanisi. and greg cochran: All One Species?

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.”

But if ‘corrupt’ behaviors are an ordinary part of governance supported by political institutions, there will be no corruption gender gap.'” – h/t jayman!

Politicians like power – from steve sailer.

Study: The Neg Works – (~_^) – @heartiste.

Some people are feminine – get over it“Whenever you have one group of people who believe one thing for ideological reasons, and another who believe something else because their business model depends on it, I tend to trust the latter. Who do you think knows more about the minds of girls and boys — the academics who’ve spent years discussing gender feminism, or people who sell toys?” (~_^) – from ed west.

Stephen Hsu on Cognitive Genomics“At the extremes, there are some academics and social activists who violently oppose any kind of research into the genetics of cognitive ability. Given that the human brain — its operation, construction from a simple genetic blueprint, evolutionary history — is one of the great scientific mysteries of the universe, I cannot understand this point of view.”

Heritability estimates and unexplained variance“Nobody owns unexplained variance.” – from dr. james thompson.

Why do haters have to hate? Newly identified personality trait holds clues“New research has uncovered the reason why some people seem to dislike everything while others seem to like everything. Apparently, it’s all part of our individual personality – a dimension that researchers have coined ‘dispositional attitude.'”

Everyday sadists take pleasure in others’ pain“[P]eople who score high on a measure of sadism seem to derive pleasure from behaviors that hurt others, and are even willing to expend extra effort to make someone else suffer.” – yeah. you know who you are.

Making The Right Mistakes: Error Management And The Evolution Of Errors“Human cognitive mechanisms evolved to deal with the problems of the past, where we spent 99% of our history, not those of the present. We should, therefore, hardly expect our brains to perform well all the time in modern settings where the social and physical environment is so different.”

From Slavs to Slaves“Between 1500 and 1650, Eastern Europe exported 1.5 million slaves to North Africa, the Middle East, and South Asia. Western Europe exported a little over a million between 1530 and 1780.” – from peter frost.

not sure if this is a late linkfest from this past sunday or an early linkfest for next sunday…. (~_^)

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.!

Law alone?“People of northwestern European descent put the least emphasis on the blood bond of a nation’s population…. The paradox presented here for many like myself is that the places inspiring the warmest feelings and that I would like most to live in are the places that tend to put the least effort into maintaining what they have. 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.

Link between low vitamin D blood levels and heart disease varies by race“Low vitamin D blood levels are linked to greater risk of heart disease in whites and Chinese, but not in blacks and Hispanics.”

Nature, nurture, and expertise“More than half of the difference between expert and normal readers is genetic…. Less than a fifth of the expert-normal difference is due to shared environment.” – via mr. mangan, esq.! see also dr. james thompson.

‘Genes’ a reason poor kids struggle at school, says [an australian] government report“In a controversial new report released today, the Productivity Commission cites ‘parents’ cognitive abilities and inherited genes’ as one of five main reasons why kids from low-income families lag behind those from wealthy homes.” – surely heads must be rolling!

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!
