«Considered in total, this study provides important early archaeological evidence for meat eating, hunting and scavenging behaviors - cornerstone adaptations that likely facilitated brain expansion in human evolution, movement of hominins out of Africa and into Eurasia, as well as important shifts in our social behavior, anatomy and physiology,» Ferraro said.

A new study from the George Washington University's Center for the Advanced Study of Human Paleobiology (CASHP) found that whereas brain size evolved at different rates for different species, especially during the evolution of Homo, the genus that includes humans, chewing teeth tended to evolve at more similar rates.

For more than three decades evolutionary psychologists have advanced a simple theory of human sexuality: because men invest less reproductive effort in sperm than women do in eggs, men's and women's brains have been shaped differently by evolution.

Rather than inheriting big brains from a common ancestor, Neandertals and modern humans each developed that trait on their own, perhaps favored by changes in climate, environment, or tool use experienced separately by the two species «more than half a million years of separate evolution,» writes Jean - Jacques Hublin, a paleoanthropologist at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, in a commentary in Science.
