Genetics, Puberty and African American Girls“Out of 42 SNPs associated with age at menarche in European women, 25 were also associated with the trait in African-American women, bolstering the evidence that these genes genetic variants are tied to menarche timing. However, they also found variants in eight regions of the genome that were more strongly associated with age at menarche in African-American women than in European-American women.”

Genetic switches play big role in human evolution“A Cornell Univ. study offers further proof that the divergence of humans from chimpanzees some 4 million to 6 million years ago was profoundly influenced by mutations to DNA sequences that play roles in turning genes on and off. The study, published in Nature Genetics, provides evidence for a 40-year-old hypothesis that regulation of genes must play an important role in evolution since there is little difference between humans and chimps in the proteins produced by genes.”

The Causes of Group Differences in Intelligence Studied Using the Method of Correlated Vectors and Psychometric Meta-Analysis“It is concluded that these findings are strongly in line with a substantial genetic component in group differences in intelligence. This suggest that the large group differences in school achievement and work achievement are stable and that I/O psychologists should find ways to deal with them instead of ways of trying to change them.” – @meng hu’s blog! via hbd bibliography.

Researchers conclude that what causes menopause is — wait for it — men“[M]enopause is actually an unintended outcome of natural selection – the result of its effects having become relaxed in older women.

J.P. Rushton’s theory of ethnic nepotism [pdf] – “Ethnic nepotism due to similarity is a weak social force compared to social identity. However its pervasiveness makes it a potential driver of evolutionary and social change, a potential borne out by sociological studies of the impact of ethnic diversity on social cohesion and public altruism. Genomics confirms the theory for interactions within populations with sufficient genetic diversity, such as ethnically mixed societies. GST [genetic similarity theory] applied to ethnicity is promising for further research in evolutionary social science because it unifies evolutionary and behavioral mechanisms in a single theory.” – from salter and harpending. h/t hbd bibliography!

The team believes this is due to multiple large migrations throughout Chinese history.”
