Weird Evolutionary Science

See an article from The National Interest which examines why human societies are characterized by warfare. Guess what? Our closest relatives in the animal kingdom - chimpanzees - are brutal, organized killers. You may enjoy the conclusion:

The true source of the tragedy of the human condition is that we evolved in conditions of intense resource competition. Like Russell Crowe organizing the outnumbered combatants in Gladiator, natural selection favored individuals who cooperated to avoid being killed—and, if necessary, to kill. Regrettably, Einstein's concise question, “Why war?”, is answered by nature equally succinctly: because we are human.

No dispassionate student of human history could reach any other conclusion. Humans are the true killer ape.
