Ancient Jomon people not like present-day East Asians“‘We found a unique genetic position of the Jomon people who had diverged before the diversification of most of present-day East Eurasian populations including East Eurasian Islanders. This indicates that Jomon people were a basal population in East Eurasia and genetically isolated from other East Eurasians for long time.'” – h/t charles!

Uncovering the Genetic History of the Present-Day Greenlandic Population“[W]e analyzed ∼200,000 SNPs from more than 10% of the adult Greenlandic population (n = 4,674). We found that recent gene flow from Europe has had a substantial impact on the population: more than 80% of the Greenlanders have some European ancestry (on average ∼25% of their genome). However, we also found that the amount of recent European gene flow varies across Greenland and is far smaller in the more historically isolated areas in the north and east and in the small villages in the south. Furthermore, we found that there is substantial population structure in the Inuit genetic component of the Greenlanders and that individuals from the east, west, and north can be distinguished from each other. Moreover, the genetic differences in the Inuit ancestry are consistent with a single colonization wave of the island from north to west to south to east. Although it has been speculated that there has been historical admixture between the Norse Vikings who lived in Greenland for a limited period ∼600–1,000 years ago and the Inuit, we found no evidence supporting this hypothesis. Similarly, we found no evidence supporting a previously hypothesized admixture event between the Inuit in East Greenland and the Dorset people, who lived in Greenland before the Inuit.” – h/t razib!

Estimating the genotypic intelligence of populations and assessing the impact of socioeconomic factors and migrations – from davide piffer who tweeted: “New version of my paper with genetic distances. Migrations or drift less likely to explain results.” also, from the paper: “The results also provide preliminary evidence in favor of the hypothesis that poor environmental conditions (i.e. economic and sociocultural) tend to depress national IQ scores. Countries with lower per capita GDP and a lower index of Human Development tended to have larger positive ‘residuals’, that is the difference between the score predicted by the regression (of IQs for developed countries on the 4 SNPs g factor) and the actually measured IQ was larger in countries with lower GDP and HDI (r around 0.7). Thus, poorer and less developed countries have yet to reach their full intellectual potential. The results of this study indicate that the gaps in intellectual performance between some populations can be narrowed via adequate improvement of environmental conditions, however the overall pattern of intellectual scores is due to relatively stable and fixed (genetic) factors and cannot be substantially altered.” – see also terrific post from anatoly karlin on this paper!: Genetics, IQ, and Convergence.

Geographical Variation in Dementia: Examining the Role of Environmental Factors in Sweden and Scotland“We found a 2- to 3-fold geographical variation in dementia odds in Sweden, after twin random effects — likely to capture genetic and shared environmental variance — were removed. In Scotland, we found no variation in dementia odds in childhood but substantial variation, following a broadly similar pattern to Sweden, by adulthood. Conclusion: There is geographical variation in dementia rates.” – h/t erwin schmidt! – also Genetics and Underlying Pathology of Dementia.

Archaeogenomic insights into the adaptation of plants to the human environment: pushing plant–hominin co-evolution back to the Pliocene“The colonization of the human environment by plants, and the consequent evolution of domesticated forms is increasingly being viewed as a co-evolutionary plant–human process that occurred over a long time period, with evidence for the co-evolutionary relationship between plants and humans reaching ever deeper into the hominin past. This developing view is characterized by a change in emphasis on the drivers of evolution in the case of plants. Rather than individual species being passive recipients of artificial selection pressures and ultimately becoming domesticates, entire plant communities adapted to the human environment.” – h/t george perry!

Are flu shots effective? Your genetics determine how the immune system responds

Environment, more than genetics, shapes immune system“Everyone’s immune system is slightly different—a unique mixture of hundreds of these cells and proteins. But the main driver of this variation is unclear. Although scientists know that our immune system can adapt to our environment—that’s why vaccines work, for instance—it is also built by our genes…. After recruiting 210 identical and fraternal twins between 8 and 82 years old, Davis and colleagues took blood samples and measured more than 200 parameters of their immune systems. For example, they measured the numbers of 95 kinds of immune cells and 51 kinds of proteins. Today, the researchers report online in Cell that identical twins’ immune systems were too different for the variation to boil down to genetics. Indeed, environment overshadowed inheritance in three-quarters of the measurements, and half showed no measurable genetic influence. Moreover, younger twins were more similar than were older twins, evidence that as the twins aged and were exposed to different environments, their immune systems diverged over time.”

Levels of Selection Are Artefacts of Different Fitness Temporal Measures“I show by comparing the fitness of individuals with that of collectives of individuals in the same environment and over the same period of time – as required to decide if one or more levels of selection is acting in a population – that the selection of collectives is a by-product of selection at the individual level; thus, talking about two or more levels of selection represents merely a different perspective on one and the same process.”

Does incidental disgust amplify moral judgment? A meta-analytic review of experimental evidence [pdf] – “We meta-analyzed all available studies, published and unpublished, that experimentally manipulated incidental disgust prior to or concurrent with a moral judgment task (k=50). We found that there is evidence for a small amplification effect of disgust (d=.11), which is strongest for gustatory/olfactory modes of disgust induction. However, there is also some suggestion of publication bias in this literature, and when this is accounted for, the effect disappears entirely (d=-.01). Moreover, prevalent confounds mean that the effect size that we estimate is best interpreted as an upper bound on the size of the amplification effect. The results of this meta-analysis argue against strong claims about the causal role of affect in moral judgment and suggest a need for new, more rigorous research on this topic.” – h/t stuart ritchie!

The Scariest Explanation for America’s Vast Prison Population: We Want It That Way“[I]n federal prisons at least, Hispanics have overtaken blacks in the dubious distinction of being the most disproportionately imprisoned. Nor can we blame the war on drugs. The idea that vast numbers of Americans are in prison for smoking pot or snorting blow turns out to be a fantasy. About 20 percent of inmates are in for drug-related crimes, but those crimes are rarely limited to their own casual use. According to a 2004 estimate, only about 12,000 people were incarcerated for simple possession, without intent to traffic or distribute.”

Legal Recognition of Same-Sex Couples and Family Formation“It has long been debated how legalizing same-sex marriage would affect (different-sex) family formation. In this article, I use data on OECD member countries for the period 1980–2009 to examine the effects of the legal recognition of same-sex couples (through marriage or an alternative institution) on different-sex marriage, divorce, and extramarital births. Estimates from difference-in-difference models indicate that the introduction of same-sex marriage or of alternative institutions has no negative effects on family formation…. In addition, the country-by-country case studies provide evidence of homogeneity of the estimated effects.”

Archaeologists unearth remains of oldest Norman ever found which ‘fills gap in our knowledge of pre-Neanderthal evolution’“On a bend of the river Seine near Rouen in Normandy, archaeologists have found the remains of the oldest Norman ever discovered. The three bones from the left arm of a pre-Neanderthal should shed fresh light on a little-known period. In particular, they could help scientists to understand the evolution of the squat, muscular hunters who died out 30,000 to 40,000 years ago, just after the first humans arrived in what is now Europe. The discovery of the bones at Tourville-la-Rivière, 14km south of Rouen, is exceptional because ‘this is a period with very few fossils’, according to Bruno Maureille, a palaeontologist at the National Centre for Scientific Research. He said the arm bones, dating from 200,000 years ago, in the Middle Pleistocene era, were ‘the only known example from northern Europe’.”

coolest story! a MUST READ!: Finding Clues in Genes of ‘Exceptional Responders’“One study at Memorial Sloan-Kettering Cancer Center tested a drug called everolimus that is approved for kidney and breast cancer. Researchers asked if it could treat bladder cancer. Forty-five patients received the drug. Two responded. ‘The verdict was, “O.K., I guess everolimus does not work in bladder cancer,” ‘ said Dr. David Solit, the principal investigator. But then there were those two patients — one, in particular. Her cancer had spread to her abdomen. She was expected to live less than a year, and there was no treatment for her. But with everolimus, her tumors disappeared. ‘I was at a clinical meeting, and everyone was saying this drug did not work,’ Dr. Solit said. ‘I said, “It worked for her.” ‘ The investigators found out why. Her cancer had a mutation in a gene that made it dependent on a protein, mTOR, for growth. Everolimus squelches the activity of mTOR. The woman is still taking everolimus, and her cancer has not recurred.”

The high heritability of educational achievement reflects many genetically influenced traits, not just intelligence“Genetic research has shown that intelligence makes a major contribution to the heritability of educational achievement. However, we show that other broad domains of behavior such as personality and psychopathology also account for genetic influence on GCSE scores beyond that predicted by intelligence. Together with intelligence, these domains account for 75% of the heritability of GCSE scores. These results underline the importance of genetics in educational achievement and its correlates.” – (because there’s more to hbd than just iq!)

The plant uses an essentially random rotation process to assign workers to positions, leading to three types of teams: (a) ethnically homogeneous teams, and teams in which (b) one or (c) both downstream workers belong to a tribe in rivalry with the upstream worker’s tribe. I find strong evidence that upstream workers undersupply non-coethnic downstream workers (vertical discrimination) and shift flowers from non-coethnic to coethnic downstream workers (horizontal discrimination), at the cost of lower own pay and total output.” – spite! it’s so funny. – h/t ben southwood!
