Chimps are mini-gorillas, not the joyful babies they used to show on TV and circus acts. Their society has been described as similar to a motorcycle gang. Some years ago they were building a road in Africa, and the researchers in the construction area started noticing grotesque carnage among the chimps there. It seems the chimps could not stand the sound of the construction equipment, so the chimp groups whose territory was being used for construction left to go into territory away from the sound. That territory belonged to another group of chimps. If one lone chimp wanders into another group's territory, they gang up and kill it. If many chimps come in, it's a war. The chimps apparently had this war, and the side which was losing fled into territory even farther away from the road construction, causing yet another war then. And so on. For several miles away from the road construction, chimp corpses were spread all over the place.
Bonobos, close relatives of the chimps, split off about 2 Million years ago and are much less violent.

This thread was prompted by a video I watched on another site, in which a group of chimps (that had males outnumbering females by a good majority) kicked out the dominant male. After a long time, the male came back. He was tortured, killed, and cannibalized.
