Chimps Caught Killing One of Their Own | Video

Chimpanzees are known to attack chimps in rival groups, but it’s rare for them to kill a member of their own group. However, researchers in Senegal witnessed just that: When a exiled alpha male chimp attempted to rejoin his group, the group killed him and then mutilated and partially cannibalized his body, according to a new study.
