Chimps Kill, Mutilate and Cannibalize Member of Own Group

A male chimpanzee named Foudouko met a horrific end when members of his former community in the wild in Senegal attacked and killed him, then mutilated and partly cannibalized his body, a new study finds. It's not uncommon for chimpanzees (Pan troglodytes) to attack and kill chimps in neighboring groups, but it's rare for the primates to kill members of their own community, the researchers said. "It was very difficult and quite gruesome to watch," Jill Pruetz, a professor of anthropology at Iowa State University, said in a statement.
