Denyse O’Leary writes: Recent findings suggest that some things we take for granted in human civilizations are much older than thought. Now, these findings are provisional but they are worth looking at. Some owl stones from 5,500 and 4,750 years ago may be children’s art: But new research suggests the palm-sized plaques decorated in geometric patterns and with two engraved circles at the top might be the work of children. Numbering in the thousands and made from slate, the owl-like objects — previously dated the stone objects to be between 5,500 and 4,750 years old — may be “the archaeological trace of playful and learning activities carried out by youngsters,” according to the team of Spanish researchers behind the new study… They suggest Read More ›

Killer whales and chimpanzees also shared a combination of personality traits for conscientiousness (e.g., constant, stubborn and protective) and agreeableness (e.g., patient, peaceable and not bullying), along with some personality traits relating to dominance. The findings may suggest some evolutionary convergence where the personality traits of killer whales and primates are similar because of the advanced cognitive abilities required for complex social interactions. “Killer Whales Share Personality Traits with Humans, Chimpanzees” at Read More ›
