New genetic light shed on human evolution – “A new genetic study of a group of sub-Saharan peoples has challenged the prevailing view that modern humans emerged from one location in Africa before spreading out across the world.” – see also Complex origins and natural selection of the Khoe-San from dienekes. and also African neighbours divided by their genes.
Out-of-Asia and Into-Africa (?) – “[I]t is very likely that there was indeed such a migration into East Africa. What Pickrell et al. have added to our knowledge is that this migration is fairly recent.” – from dienekes.
Are We Really Getting Smarter? – from james flynn.
Genetic Obesity Risk Heightened by Sugary Drinks – “[P]ersons with a greater genetic predisposition to obesity appeared to be more susceptible to the deleterious effects of sugar-sweetened beverages on BMI….”
speaking of fat: Human biodiversity in adiposity – “[T]he manner in which fat is deposited in the body, e.g. viscerally vs. subcutaneously, as well as the amount of fat deposited, is substantially heritable, varies between races, and that variation may be due to differences in infectious disease risk over time periods long enough for natural selection to act.” – @the breviary.

bonus bonus bonus bonus: How the Tabby Got Its Stripes: It’s in the Genes – “Tabby cats get their stripes from two important genes, according to new research — the same genes that create a rare ‘king’ cheetah’s stripes. Cats with narrow stripes, the so-called ‘mackerel’ pattern, have a working copy of the gene. But if a mutation turns the gene off, the cat ends up with the blotchy ‘classic’ pattern.”
