In 1998, researchers in Uganda saw a group of male chimpanzees beating on and swaggering around another male chimp's freshly killed body. Its windpipe, fingernails and testicles were torn out.
The finding added to a growing number of documented incidents of chimpanzees ganging up on, hunting down and killing each other--activities in which some researchers find eerie parallels to human war. These scientists argue that the killings among chimps, our closest ape relatives, may offer clues to war's evolutionary origins, lessons that could help us break our own violent habits. |
