Summary

Researchers have proposed that bonobos evolved domesticated behavior to encourage group living. By isolating a group of 40 putative brain domestication genes in the prefrontal cortex and comparing their expression in humans versus chimps and bonobos, researchers found that the activity of that gene group in bonobos was clearly "domesticated" compared with chimps, they reported at the Biology of Genomes meeting.
