Svante Paabo talk at NIH“According to Dr. Paabo, Ust-Ishim has longer Neandertal chunks than modern humans and this can be used to estimate that the admixture with Neandertals happened 331+/-99 generations before its time of 45,000y BP, or around 50-60,000y BP…. This pretty much proves that there were modern humans in Eurasia before the Upper Paleolithic revolution and disproves Richard Klein’s theory that modern humans together with UP technologies spread Out-of-Africa only after 50,000 years ago.” – from dienekes.

Europeans have three times more Neanderthal genes for lipid catabolism than Asians or Africans“Contemporary Europeans have as many as three times more Neanderthal variants in genes involved in lipid catabolism than Asians and Africans. Although Neanderthals are extinct, fragments of their genomes persist in modern humans. These shared regions are unevenly distributed across the genome and some regions are particularly enriched with Neanderthal variants.”

The really old Europe is mostly in Eastern Europe“‘These results confirm Sardinia as a refuge area where ancestry related to Early European Farmers has been best preserved, and also the greater persistence of WHG-related ancestry in present-day Eastern European populations. The latter finding suggests that West European Hunter-Gatherers (so-named because of the prevalence of Loschbour and La Braña) or populations related to them have contributed to the ancestry of present-day Eastern European groups.'” – @eurogenes blog.

More on Deafness“Seems to me that limited verbal stimulation is not a very plausible primary cause of low test scores and low academic achievement in blacks, because the degree of deprivation needed to cause a 1-standard deviation decline is extreme (deafness), and because there is an even greater depression of nonverbal scores, which, judging from the results in deaf children, should not be affected at all by limited verbal stimulation.” – from greg cochran.

Language structure: You’re born with it“Humans are unique in their ability to acquire language. But how? A new study shows that we are in fact born with the basic fundamental knowledge of language, thus shedding light on the age-old linguistic ‘nature vs. nurture’ debate.”

Selection for complex traits leaves little or no classic signatures of selection“We present empirical evidence to suggests little discernible ‘selection signature’ for complex traits in the genome of dairy cattle despite very strong and recent artificial selection.” – h/t razib!

Whole genome sequencing of six dog breeds from continuous altitudes reveals adaption to high-altitude hypoxia“To understand the genetic bases of adaption to high altitude in dogs, we performed whole-genome sequencing of 60 dogs including five breeds living at continuous altitudes along the Tibetan plateau from 800 to 5,100 m as well as one European breed…. Comparison of the breeds from different altitudes reveals strong signals of population differentiation at the locus of hypoxia-related genes including endothelial Per-Arnt-Sim (PAS) domain protein 1 (EPAS1) and beta hemoglobin cluster. Especially, four novel non-synonymous mutations specific to high-altitude dogs are identified at EPAS1, one of which occurred at a quite conserved site in the PAS domain. The association testing between EPAS1 genotypes and blood-related phenotypes on additional high-altitude dogs reveals that the homozygous mutation is associated with the decreased blood flow resistance, which may help to improve hemorheologic fitness. Interestingly, EPAS1 was also identified as a selective target in Tibetan highlanders, though no amino acid changes were found. Thus, our results not only indicate parallel evolution of humans and dogs in adaption to high-altitude hypoxia, but also provide a new opportunity to study the role of EPAS1 in the adaptive processes.” – h/t joe pickerell!

Facial Width-To-Height Ratio Relates to Alpha Status and Assertive Personality in Capuchin Monkeys“fWHR was positively associated with alpha status and with a dimensional rating of assertive personality in both males and females. Moreover, fWHR showed significant sexual dimorphism in adults but not juveniles, suggesting a developmental change may occur during puberty. In a sub-sample, sex differences were mediated by weight, suggesting fWHR dimorphism does not exceed what would be expected by differences in body weight. This is the first report of an association between face shape and behaviour in a non-human species.” – h/t stuart ritchie!

The relationship between Microcephalin, ASPM and intelligence: A reconsideration“Microcephalin is strongly associated with DNA repair, which indicates a special role for this allele in the intrinsic anti-viral immune response. Enhanced immune functioning may have advantaged both hunter–gatherer and agrarian societies coping with the heightened disease burden that resulted from population growth and exposure to zoonotic diseases, making it more likely that such growth and concomitant increases in intelligence could occur.” – from michael woodley et al. – see also The riddle of Microcephalin – from peter frost.

Caucasian Boys Show Highest Prevalence of Color Blindness Among Preschoolers“The first major study of color blindness in a multi-ethnic group of preschoolers has uncovered that Caucasian male children have the highest prevalence among four major ethnicities, with 1 in 20 testing color blind. Researchers also found that color blindness, or color vision deficiency, in boys is lowest in African-Americans, and confirmed that girls have a much lower prevalence of color blindness than boys.”

Genetic Influences Are Virtually Absent for Trust“Here we examine a population-based sample of 1,012 twins and relatives. We show that the genetic influence on generalized trust in other people (trust-in-others: h2 = 5%, ns), and beliefs regarding other people’s trust in the self (trust-in-self: h2 = 13%, ns), is virtually absent…. We show that, relative to cognitive abilities, psychiatric disorders, and classic personality variables, genetic influences are smaller for trust, and propose that experiences with or observations of the behavior of other people shape trust more strongly than other traits.” – h/t rene bekkers!

If someone’s brain lacks the moral niceties the rest of us take for granted, they obviously can’t do anything about that, any more than a colour-blind person can start seeing colour. So where does this leave the concept of moral responsibility? ‘The legal system traditionally asserts that all people standing in front of the judge’s bench are equal. That’s demonstrably false,’ says the neuroscientist David Eagleman, author of Incognito: The Secret Lives of the Brain. He suggests that instead of thinking in terms of blameworthiness, the law should deal with the likelihood that someone will reoffend, and issue sentences accordingly, with rehabilitation for those likely to benefit and long sentences for those likely to be long-term dangers.” – h/t (heh!

The truth is that of course men and women are equal (all human beings are equal), but this does not mean that they are, on average, the same. 2 + 3 = 10 – 5, but these expressions are not the same. And, in fact, if two groups really are different on average in some respect, but they are being treated the same, then they are not being treated equally on average.”

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?

speaking of species: Roe Deer × Domestic Sheep“This rather distant cross, which represents a case of interbreeding between separate mammalian families (Cervidae × Bovidae) was reported in the last decade of the 18th century by the Finnish academic Carl Niklas Hellenius (1745-1820), also known as Carl Niklas von Hellens (or af Hellens).” – say what?!

Evolution is not a one-way road towards complexity“[T]he fact that the highly complex larval muscular bodyplan is so similar in both groups [aplacophorans and chitons] but is only carried over into the adult stage in one of them — the chitons — strongly suggests that the common ancestor of both groups was of similar complexity; thereby implying that the worm-like groups lost these complex traits and became secondarily simplified over evolutionary time.”

On the other hand, if the soil varies considerably then the yields will vary partly because of seed quality, and partly because of soil quality.” – from dr. james thompson.

A focused gene set analysis suggests that some of the overall correlation can be explained by specific systems; for example, an olfactory gene set is homophilic and an immune system gene set is heterophilic.” – via charles!

I began using commonly known ways to ‘measure’ relatedness between organisms — Sewall Wright’s coefficient of inbreeding and its extended concept, the coefficient of relatedness. This was very unusual in cultural anthropology. In short, I was discussing Yanomamö kinship with *the biological meaning* of kinship in mind — at a time when the vast majority of cultural anthropologists assumed that ‘kinship’ and ‘the biological meaning of Yanomamö kinship’ were, at best, only vaguely similar and any allusion to this was generally ‘suspect.’ But since ‘kinship’ was traditionally a central focus of anthropological theory, I began developing ways to show precisely, using my meticulous genealogies on the Yanomamö, that people took sides in fights according to how closely *genetically* they were related to each other and fought against people they were *less related to genetically*. Many of the most prominent anthropologists held the extreme view that ‘kinship’ among humans had *nothing* to do with the biological meaning of kinship as is assumed in the fields of biology, genetics, or animal husbandry. A common claim was something to the effect that ‘whatever kinship among humans was about, it was NOT about biology.'” – h/t g-nice!
