Evidence for "demonic male ape" is flimsy

Story here. I find this article of interest because it argues against the theory of the "demonic male" among apes. I have literally seen the argument made that men make lousy parents because male lions or polar bears allegedly kill their young. But such killings among apes, at least, are apparently rare--as is other war-like behavior. Excerpt:

'An important essay by columnist John Horgan that was published in 2010 in Scientific American summarizes much of what is known about warfare in great apes and other primates. Horgan is especially concerned with what is called the "demonic male" theory that states "both male humans and chimpanzees, our closest genetic relatives, are 'natural warriors' with an innate predisposition toward 'coalitionary killing,' which dates back to our common ancestor." Horgan summarizes what is actually known as follows: "All told, since Jane Goodall began observing chimpanzees in Tanzania's Gombe National Park in 1960, researchers have directly observed 31 intergroup killings, of which 17 were infants.... researchers at a typical site directly observe one killing every seven years ... my criticism -- and that of other critics I've cited -- stems from science, not ideology. The evidence for the demonic-males theory, far from extraordinary, is flimsy."'
