Ancient Ethiopian genome reveals extensive Eurasian admixture throughout the African continent“Here, we present a 12.5x coverage ancient genome of an Ethiopian male (‘Mota’) who lived approximately 4,500 years ago. We use this genome to demonstrate that the Eurasian backflow into Africa came from a population closely related to Early Neolithic farmers, who had colonized Europe 4,000 years earlier. The extent of this backflow was much greater than previously reported, reaching all the way to Central, West and Southern Africa, affecting even populations such as Yoruba and Mbuti, previously thought to be relatively unadmixed, who harbor 6-7% Eurasian ancestry.” – h/t john hawks! who tweeted: “First ancient DNA from Ethiopia shows that today’s sub-Saharan Africans are at least 0.2-0.7% Neanderthal ancestry!” – see also: First Ancient African Genome Reveals Vast Eurasian Migration“The man’s genome is, unsurprisingly, more closely related to present-day Ethiopian highlanders known as the Ari than to any other population the team examined, suggesting a clear line of descent for the Ari from ancient human populations living in the area. But further genetic studies show that the Ari also descend from people that lived outside Africa, which chimes with a previous study that discovered a ‘backflow’ of humans into Africa from Eurasia around 3,000 years ago.”

Eight thousand years of natural selection in Europe“The arrival of farming in Europe around 8,500 years ago necessitated adaptation to new environments, pathogens, diets, and social organizations…. We identify genome-wide significant signatures of selection at loci associated with diet, pigmentation and immunity, and two independent episodes of selection on height…. These results suggest that the modern South-North gradient in height across Europe is due to both increased steppe ancestry in northern populations, and selection for decreased height in Early Neolithic migrants to southern Europe. “

The Hybrid Origin of “Modern” Humans“Recent genomic research has shown that hybridization between substantially diverged lineages is the rule, not the exception, in human evolution. However, the importance of hybridization in shaping the genotype and phenotype of Homo sapiens remains debated. Here we argue that current evidence for hybridization in human evolution suggests not only that it was important, but that it was an essential creative force in the emergence of our variable, adaptable species.”

Neanderthal ‘flower children’ burials theory debunked“New research casts doubt on the idea that Neanderthals buried their dead covered in flowers.”

Intelligence in youth and health at age 50“Higher intelligence in youth is linked with better physical health at age 50.” – h/t andrew sabisky!

Chorionicity and Heritability Estimates from Twin Studies: The Prenatal Environment of Twins and Their Resemblance Across a Large Number of Traits“There are three types of monozygotic (MZ) twins. MZ twins can either share one chorion and one amnion, each twin can have its own amnion, or MZ twins can—like dizygotic twins—each have their own chorion and amnion. Sharing the same chorion may create a more similar/dissimilar prenatal environment and bias heritability estimates…. We conclude that the influence on the MZ twin correlation of the intra-uterine prenatal environment, as measured by sharing a chorion type, is small and limited to a few phenotypes.”

Genetic transmission of reading ability – h/t steve stewart williams! who tweeted: “If you want your kids to read, your best bet is to have kids with a reader.”

It All Began at Ararat, and Esau’s Revenge“Ancient DNA in Europe strongly indicates massive replacement [of hunter-gatherers by agriculturalists]. But, there is also suggestion of admixture with the local substrate. And, unlike the stylized model of Bellwood, it seems that there were multiple migrations after the initial pulse which reshaped the genetic and cultural landscape of human societies in the wake of agriculture.” – from razib.

Closing the Black-White IQ Gap Debate, Part I – from chanda chisala. and a response from peter frost: No, blacks aren’t all alike. Who said they were? – and previously on this blog: there’s more to human biodiversity than just racial differences.

The Association of Cognitive Ability with Right-wing Ideological Attitudes and Prejudice: A Meta-analytic Review“The present meta-analyses revealed an average effect size of r = −.20 [95% confidence interval (95% CI) [−0.23, −0.17]; based on 67 studies, N = 84 017] for the relationship between cognitive ability and right-wing ideological attitudes and an average effect size of r = −.19 (95% CI [−0.23, −0.16]; based on 23 studies, N = 27 011) for the relationship between cognitive ability and prejudice.”

[male] Chimps like boys toys too“If you want to know why young boys play with toy guns, you could do worse than consider why young male chimpanzees play with leaves and stones.” – h/t darren burke! who tweeted: “Western social constructivism is so insidious and widespread it is even affecting wild chimpanzees now!” – (~_^)

Personality Traits Increasingly Important for Male Fertility: Evidence from Norway“[P]ersonality relates to men’s and women’s fertility differently; conscientiousness decreases female fertility, openness decreases male fertility and extraversion raises the fertility of both sexes. Neuroticism depresses fertility for men, but only for those born after 1956.”

Host genetic variation impacts microbiome composition across human body sites“Our results highlight the role of host genetic variation in shaping the composition of the human microbiome, and provide a starting point toward understanding the complex interaction between human genetics and the microbiome in the context of human evolution and disease.”

Women and men react differently to infidelity“While men are most jealous of sexual infidelity, women are most jealous of emotional infidelity.” – w.e.i.r.d. study. (n=1000).

‘Safe spaces’ exist because universities treat secular ideas as sacred“The most influential effect of this cultural and political imbalance is that academia has ignored the increasing evidence that human traits are heavily influenced by hereditary factors, most prominently in intelligence and sexual differences. This has a huge bearing on public policy, especially when so much of policy is involved in tackling inequality of various kinds. It would be like trying to reduce economic inequality while pretending that wealth cannot be inherited, because that’s offensive to people’s parents, and that all fortunes were the results of education, hard work or sheer luck.” – from ed west.

Relics of the Blank Slate, as Excavated at “Ethics” Magazine“There’s a reason that the Blank Slaters clung so bitterly to their absurd orthodoxy for so many years. If there is such a thing as human nature, then all the grandiose utopias they concocted for us over the years, from Communism on down, would vanish like so many mirages.” – from helian.

Anthropologist: “I’ve Never Been So Disgusted with My Own Data” – from steve sailer.

Excavations at Mexican ruin site yields new details of Aztecs’ sacrifice of captured Spaniards“It was one of the worst defeats in one of history’s most dramatic conquests: Only a year after Hernan Cortes landed in Mexico, hundreds of people in a Spanish-led convey were captured, sacrificed and apparently eaten.”

bonus: Most worker ants are slackers“[N]ew research shows that many ants in a colony seem to specialize in doing nothing at all. To get a closer look at how these ants filled their time, researchers marked every member of five lab-based colonies with dots of colored paint. Over the course of 2 weeks, a high-definition camera recorded 5-minute segments of the ants in action six times a day, capturing their behavior (or lack thereof). Out of the ‘workers,’ 71.9% were inactive at least half the time, and 25.1% were never seen working. A small fraction of the ants, just 2.6%, were always active during observation, the researchers wrote last month in Behavioral Ecology and Sociobiology.”

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….'”

Self-heal like Wolverine? Gene discovery might hold clues“In a discovery by a Harvard researcher, a reactivated gene found in embryos helps mice regrow clipped parts of their ears and toes. Could the ‘fountain of youth’ gene hold promise for humans too?” – i want one! – h/t mike anissimov!

Gene Variants Up CKD [chronic kidney disease] Risk in Blacks“A high-risk genetic variant conferred a significantly increased risk of progressive kidney disease in African Americans, at least partly explaining a racial disparity in end-stage renal disease (ESRD), investigators reported here. Analysis of black and white patients in another trial — half with diabetes — showed kidney function declined almost three times as fast in blacks with the high-risk APOL1 profile as compared with whites….”

Genetic clue to high heart risk of black Americans“The gene that produces the protein [PC-TP which activates a clotting factor called PAR4] is four times more active in the platelets of black Americans than it is in white Americans.” – h/t hbd bibliography!

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.”

In Hookups, Inequality Still Reigns“[A] study of 24,000 students at 21 colleges over five years found that about 40 percent of women had an orgasm during their last hookup involving intercourse, while 80 percent of men did.” – h/t john durant!

The Co-Villains Behind Obesity’s Rise“Not everyone, however, has the same gut bacteria. And, interestingly, the composition of this bacteria correlates with obesity…. [T]he bacteria study found that the ‘obese gut bacteria’ had an impact only when the mice were fed diets heavy in saturated fats.” – h/t jayman!

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!

CRISPR gene therapy: Scientists call for more public debate around breakthrough technique“‘I’m sure there will be some concern about the possibility that the technology could be used for “enhancement” rather than repair, veering from medicine towards eugenics,’ [professor wells] warned.” – oh noes! not “enhancement”! *swoon!* h/t anatoly!

John Derbyshire’s Modest Proposal On Politics and Intelligence“And the too-dumb-to-vote segment is only a part of the problem we conservatives have with universal suffrage. Here’s another part: too *smart* to vote…. At the very highest levels of intelligence, the correlation between IQ and sensible political opinions may actually be *inverse*: the more brilliant you are, the dumber your politics. Albert Einstein thought well of Stalin; Hitlerism got its first mass following in the highly-selective German universities.”

following my post of yesterday about the secular right smarties, i happened to notice that the lower the wordsum score, the more moderates to be found. so, i ran a search (on the gss) for POLVIEWS + WORDSUM minus the GOD variable (n=22,022) and, sho nuff, dumb people tend to be more moderate politically. waaaay more moderate.

something like, i dunno, 60%+ of the people who scored 1 on the wordsum test call themselves moderates (do they know what the word means?). on the other hand, people who scored a perfect 10 are more (dare i say it) diverse in their political leanings — more of them are liberal, more of them are conservative, less of them are moderates.

so, thinking people tend to have stronger political opinions? they think, therefore they are politically opinionated?
