The genetics of Mexico recapitulates Native American substructure and affects biomedical traits“We studied genomic variation within Mexico from over 1000 individuals representing 20 indigenous and 11 mestizo populations. We found striking genetic stratification among indigenous populations within Mexico at varying degrees of geographic isolation. Some groups were as differentiated as Europeans are from East Asians. Pre-Columbian genetic substructure is recapitulated in the indigenous ancestry of admixed mestizo individuals across the country. Furthermore, two independently phenotyped cohorts of Mexicans and Mexican Americans showed a significant association between subcontinental ancestry and lung function. Thus, accounting for fine-scale ancestry patterns is critical for medical and population genetic studies within Mexico, in Mexican-descent populations, and likely in many other populations worldwide.” – see also: People from Mexico show stunning amount of genetic diversity“When the team analyzed the genomes of 511 indigenous individuals from all over Mexico, they found a striking amount of genetic diversity. The most divergent indigenous groups in Mexico are as different from each other as Europeans are from East Asians, they report online today in Science. This diversity maps onto the geography of Mexico itself. The farther away ethnic groups live from each other, the more different their genomes turn out to be…. But most people in Mexico or of Mexican descent these days are not indigenous but rather mestizo, meaning they have a mixture of indigenous, European, and African ancestry. Do their genomes also vary by what region of Mexico they come from, or has all that local variation been smoothed out by centuries of different groups meeting, mixing, and having babies? To answer that question, the team collaborated with Mexico’s National Institute of Genomic Medicine, which has been collecting genetic data from mestizos for many years. Somewhat surprisingly, they found that mestizos in a given part of Mexico tended to have the same ‘rare’ genetic variants as their indigenous neighbors. The mestizo genomes ‘track so well with the indigenous groups that we could use the genetic diversity in mestizos to make inferences about [their native] ancestors,’ Pasaniuc says.”

Neanderthal-Human Skulls Shed Light on Evolution“Skulls found in a Spanish cave exhibit both Neanderthal and primitive human features, according to a new study published in the journal Science. The discovery provides clues about when the common ancestor of modern humans and Neanderthals lived, what happened after the two groups diverged, and how the two became so different over a relatively short period of time. There is consensus about the ending of the story: Modern humans and Neanderthals interbred, and Neanderthal DNA is still present in people of European and Asian ancestry. But the thousands of years before they connected, however, have been a mystery.” – see also: Palaeontology: How Neanderthals evolved“A study reveals that not all distinguishing features of hominid skulls have evolved at the same pace.”

Island-hopping odyssey brought civilisation to Europe“The farmers who brought advanced civilisation to Europe got there by sailing between the many islands strewn across the Aegean Sea between Greece and Turkey, according to a new genetic analysis. The first modern humans in Europe were hunter-gatherers who arrived around 40,000 years ago. But around 9000 years ago the first farmers arrived. They spread rapidly, dominating the continent by 7500 years ago, and pushing the hunter-gatherers into decline. The farmers originated in the Fertile Crescent in the Middle East, where farming arose, but until now no one knew which route they took to get to Europe.” – see also Publication Delays from greg cochran.

The population genomic landscape of human genetic structure, admixture history and local adaptation in Peninsular Malaysia“Peninsular Malaysia has greater genetic diversity corresponding to its role as a contact zone of both early and recent human migrations in Asia. However, each single Orang Asli (indigenous) group was less diverse with a smaller effective population size (Ne) than a European or an East Asian population, indicating a substantial isolation of some duration for these groups. All four MEGs were genetically more similar to Asian populations than to other continental groups, and the divergence time between MEGs and East Asian populations (12,000—6,000 years ago) was also much shorter than that between East Asians and Europeans. Thus, Malaysian Orang Asli groups, despite their significantly different features, may share a common origin with the other Asian groups. Nevertheless, we identified traces of recent gene flow from non-Asians to MEGs. Finally, natural selection signatures were detected in a batch of genes associated with immune response, human height, skin pigmentation, hair and facial morphology and blood pressure in MEGs. Notable examples include SYN3 which is associated with human height in all Orang Asli groups, a height-related gene (PNPT1) and two blood pressure-related genes (CDH13 and PAX5) in Negritos. We conclude that a long isolation period, subsequent gene flow and local adaptations have jointly shaped the genetic architectures of MEGs, and this study provides insight into the peopling and human migration history in Southeast Asia.”

Race a factor in mortality in heart attack patients on anti-clotting drug“The first genetic variations linked to race have been identified that begin to explain a higher risk of death among some African American and Caucasian patients taking the anti-clotting drug clopidogrel after a heart attack. In particular, the team found that two DNA variants common in African Americans were associated with an increased risk of both bleeding and death. In Caucasians, a different variant was linked to additional heart attacks and a higher risk of death.” – h/t hbd bibliography!

A hair-color allele of Neanderthal origin?“60-70% of Taiwanese aborigines have a loss-of-function allele at the main hair color gene, MC1R, yet their hair is as black as humans with the original ‘African’ allele. This seems to be a general pattern in Asians. They have fewer MC1R alleles than do Europeans, and the ones they have produce the same hair color.” – from peter frost.

Physical attractiveness as a phenotypic marker of health: an assessment using a nationally representative sample of American adults“[T]he more attractive a respondent was rated, the less likely he or she was to report being diagnosed with a wide range of chronic diseases and neuropsychological disorders.

Woodley launches his Victorian defence“The Woodley gang argue that, once they have done a complete re-analysis to respond to the points raised against their original ‘Victorians’ paper, their new results ‘reveal a seemingly robust secular trend towards slowing reaction time in these two countries, which translates into a potential dysgenics rate of −1.21 IQ points per decade, or −13.9 points in total between 1889 and 2004. We conclude by arguing that the best way forward is to test novel predictions stemming from our finding relating to molecular genetics, neurophysiology and alternative cognitive indicators, thus shifting the research focus away from the purely methodological level towards the broader nomological level. We thank our critics for helping us to arrive at a much more precise estimate of the decline in general intelligence.’” – @dr. james thompson’s blog.

Criminal offending as part of an alternative reproductive strategy: Investigating evolutionary hypotheses using Swedish total population data“Convicted criminal offenders had more children than individuals never convicted of a criminal offense. Criminal offenders also had more reproductive partners, were less often married, more likely to get remarried if ever married, and had more often contracted a sexually transmitted disease than non-offenders. Importantly, the increased reproductive success of criminals was explained by a fertility increase from having children with several different partners. We conclude that criminality appears to be adaptive in a contemporary industrialized country, and that this association can be explained by antisocial behavior being part of an adaptive alternative reproductive strategy.” – h/t mary lou cowan! – chicks dig jerks. – see also You dropped your glove, my liege from the awesome epigone.

For The First Time, Chimpanzees Are Making A Fashion Statement — Sticking Blades Of Grass In Their Ears“It’s a trend that’s taken a troop of chimpanzees by storm: a blade of grass dangling from an ear. The “grass-in-ear behavior,” as scientists have termed it, seems to be one of the first times that chimpanzees have created a tradition with no discernible purpose — a primate fashion statement, in other words…. There’s no genetic or ecological factors, the scientists believe, that would account for this behavior — only culture.” – but, but, but…where does chimp culture come from?

The Little Divergence“A ‘great divergence’ between the economies of Western Europe and East Asia had unambiguously occurred by 1800. However, there’s a growing body of opinion that this was preceded by a ‘little divergence’ which might have started as early as 1200. I argue that the pre-modern ‘little divergence’ was probably real, but that doesn’t mean it happened because of a modern growth process — a sustained rise in the production efficiency of the divergent economies. The ‘little divergence’ might be only a reflexion of those societies’ Malthusian balance of natality and mortality.” – from pseudo. – see also Addendum to The Little Divergence.

Mike Lotus Meeting with Emmanuel Todd in Paris, Discussing Todd’s Current Work and America 3.0“Todd spoke about the origins of the Absolute Nuclear Family, as contrasted with the Community Family which predominates in much of Eurasia. Todd said that his most recent book, ‘L’Origine des systemes familiaux’ he shows that the entire history of the world is understood backward. Specifically, the supposedly most backward places are the most advanced. He told me that he had made an absurd mistake in his early book The Explanation of Ideology: Family Structure and Social Systems. He said in Explanation that the distribution of family systems appeared to be random. But, he said, he should have realized that this could not be correct. He took out a pile of printer paper and with rapid strokes sketched an oval and filled in the center, noting that this was the community family area. It was a given that I understood that the oval was Eurasia. He then marked Xs around the periphery for England, Iceland, Finland, France, Japan, Korea, the Philippines all areas which were still individualistic in family structure. He said the book articulates the ‘Principle of Peripheral Conservation.’ The oldest known family structure is the Undifferentiated Nuclear Family (UNF). In England the UNF evolved into the ANF over many centuries. The Community Family forms took four to five thousand years to form and to reach their current state of development. In particular the subjugation of women took a very long time to complete in these systems. In other words, the societies which are currently considered the most modern have as a foundation an archaic family structure.” – h/t t.greer!

Understanding current causes of women’s underrepresentation in science“[D]ifferential gendered outcomes in the real world result from differences in resources attributable to choices, whether free or constrained, and that such choices could be influenced and better informed through education if resources were so directed. Thus, the ongoing focus on sex discrimination in reviewing, interviewing, and hiring represents costly, misplaced effort: Society is engaged in the present in solving problems of the past, rather than in addressing meaningful limitations deterring women’s participation in science, technology, engineering, and mathematics careers today.”

Results showed that some lines seemed less sensitive to new events or environmental changes and could be defined as low responsive, while others were very sensitive and defined as high responsive.” – h/t justin tiehen!

Fungus, Get Off My Lawn!“Virginia wildrye, common on U.S. prairies and rangelands, often plays host to a fungus that helps this grass grow. But the plant pays a price. Researchers have discovered that infected plants produce less pollen than their noninfected counterparts. Instead, the fungus causes the rye grass to make extra seeds, which transmit the fungus to the next generation and new locations. This is the first time a fungus has proven capable of manipulating plant reproduction.” – manipulator!

Can People’s Personalities Change?“[P]ersonality was the strongest predictor of satisfaction with life. This is well-established and helps explain why some people have everything and are never satisfied and some people have next-to-nothing and seem quite happy with life.

Misguided Nostalgia for Our Paleo Past“Gregory Cochran and Henry Harpending even suggest that human evolution as a whole has, on the contrary, accelerated over the last several thousand years, and they also believe that relatively isolated groups of people, such as Africans and North Americans, are subject to differing selection. That leads to the somewhat uncomfortable suggestion that such groups might be evolving in different directions—a controversial notion to say the least.” – i dunno why that suggestion should be uncomfortable, but i guess it is. -?- see also steve sailer.
