Chimpanzee Death: Killing Comes 'Naturally' To Chimps, But What About Humans?

Murder is an act of aggression that "comes naturally" to chimpanzees, according to a new study published in the scientific journal Nature. Researchers found that killing has become an evolved tactic for the species, and is usually done by groups of male chimps, in an effort to have better access to land, mates and other resources. The study was co-written by over 30 scientists worldwide who looked at death among 18 chimpanzee communities in Africa for over five decades.
