Most humans would choose the person they know first, if they shared at all.But bonobos, those notoriously frisky, ardently social great apes of the Congo, prefer to share with a stranger before sharing with an animal they know. In fact, a bonobo will invite a stranger to share a snack while leaving an acquaintance watching helplessly from behind a barrier."It seems kind of crazy to us, but bonobos prefer to share with strangers," said Brian Hare, a professor of evolutionary anthropology at Duke University. "They're trying to extend their social network." And they apparently value that more than maintaining the friendships they already have.
