On a number of tests bonobos show greater inclination to cooperate and share than chimps. (Humans look to see who's watching.)Chimpanzees and bonobos are our closest primate relatives, but the two apes have very different personalities. While primatologists have often noted nasty, competitive behavior among power-hungry chimps, bonobos have a reputation as free-loving peaceniks. Now, a behavioral study that directly compares the two apes suggests that the bonobos' more cordial nature enables them to cooperate more successfully than chimps in some situations.
