Bonobos have what was thought to be a uniquely human trait: they share. Researchers in Congo tested the great apes by placing one bonobo in a room that had food and another bonobo in an empty room next-door. The one with the food usually invited the other over for a bite to eat. (Chimpanzees, a closely related species, don't do this.) Bonobo generosity wasn’t dependent on kinship, pressure or past favors. Instead the animals may have expected a favor in return or they may have had "a more altruistic motivation."
