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 lost cousins of Homo sapiens in Asia and the South Pacific – on Homo denisova and Homo floresiensis.

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.”

Why Extroverts Like Parties and Introverts Avoid Crowds“[E]xtroverts are more likely to associate the rush of a feel-good brain chemical with the environment they are in at the time.” – see also: Are You an Introvert or Extrovert? Here’s How to Tell (true x 20 (^_^) ).

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.”

Sporting aggression more common in opponents of a similar ability than in contests between unequal teams“The same is also true of aggressive contests between individuals in the animal kingdom, whether it is rutting deer stags or quarrelsome Siamese fighting fish. Now scientists believe they have found evidence for the same trait in competing groups of sportsmen.”
