    Why is it that humans, nearly unique in this regard, have a natural inclination to band together and kill off members of our own species? The fact that chimpanzees, our closest evolutionary relatives, are the only other animals known to exhibit such organized warlike behavior is a big clue.Malcolm Potts and Thomas Hayden, authors of the new book Sex and War, assert that the answers lie in our biological history -- that aggression against our own species is rooted in deep evolutionary impulses and predispositions.
