More on Farming and Inheritance Systems – Part I: IQ – from jayman!

Spanish cave paintings shown as oldest in world“New tests show that crude Spanish cave paintings of a red sphere and handprints are the oldest in the world, so ancient they may not have been by modern man. Some scientists say they might have even been made by the much-maligned Neanderthals, but others disagree.”

Childhood obesity found linked to math performance“When compared with children who were never obese, boys and girls whose obesity persisted from the start of kindergarten through fifth grade performed worse on the math test, starting in first grade, and their lower performance continued through fifth grade. For boys whose obesity emerged later (in third or fifth grade), no such differences were found, and for girls who became obese later, poorer math performance was temporary.”

Why Smart People Are Stupid“[I]ntelligence seems to make things worse. The scientists gave the students four measures of ‘cognitive sophistication.’ As they report in the paper, all four of the measures showed positive correlations, ‘indicating that more cognitively sophisticated participants showed larger [cognitive] bias blind spots.'”

Scientists Sequence Genome Of Human Relative That Prefers Love Over War“They found that more than 3 percent of the human genome is more closely related to either the bonobo or the chimpanzee than the two apes are to each other, which indicates that the three species share a complex evolutionary relationship.”

“Gene Activity in the Brain Depends on Genetic Background”“Taken all together, the data from the study demonstrate that closer genetic relatives exhibit fewer differences in gene expression patterns, whereas more distant relatives show greater variation. Interestingly, the researchers found that the expression variations between genetic strains were more likely to be found in areas of the brain that evolved more recently. These regions are most commonly linked to higher order functions such as cognition, social behavior, learning and memory.”

Biologists are now divided over what, if anything, went wrong—and what needs to happen next.” (behind paywall, unfortunately.)
