Bonobos Left and Right
Whereas most observed chimpanzee killings occur during territorial disputes, bonobos engage in sex at their boundaries. They can be unfriendly to neighbors, but soon after a confrontation has begun, females have been seen rushing to the other side to copulate with males or mount other females. Since it is hard to have sex and wage war at the same time, the scene rapidly turns into socializing. It ends with adults from different groups grooming each other while their children play.
