happy father’s day to all you dads out there! (^_^)

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. Over time, human males have shown a preference for younger women in selecting mates, stacking the Darwinian deck against continued fertility in older women, the researchers have found.”

Does Geography Influence How a Language Sounds?“A linguist finds a correlation between ‘ejective consonants’ and high altitude…. Everett speculated that ejectives are easier to produce at high altitudes because air pressure decreases with altitude, and it takes less effort to compress less-dense air.”

Blacks are more likely than both Hispanics and whites to believe race was a factor in the shooting of Trayvon Martin, a black teenager. And blacks also are more likely than whites to follow the court case closely. Hispanics are less likely than all groups to follow the case closely.”

Scientists find ethnicity linked to antibodies“‘[I]t’s early days,’ emphasizes Watson, ‘but these findings could mean that past environmental exposures to certain pathogens caused DNA insertions or deletions in different ethnic groups, which could impact disease risk. Our results demonstrate that antibody studies need to take into account the ethnicity of DNA samples used.'”

Those resistant to ‘love hormone’ may also be easier to hypnotize“Gene variants linked to social detachment may increase suggestibility.”

[P]aternal first-cousin marriages constituted 27.7% of all marriages and 72% (565/786) of all first-cousin marriages, while maternal first-cousin marriages constituted 10.8% of all marriages and 28% (221/786) of all first-cousin marriages.”
