"The classic opening scene of 2001: A Space Odyssey shows an ape-man wreaking havoc with humanity's first invention - a bone used as a weapon to kill a rival. It's an image that fits well with popular notions of our species as inherently violent, with the idea that humans are - and always have been - warlike by nature. But as Douglas P. Fry convincingly argues in Beyond War, the facts show that our ancient ancestors were not innately warlike - and neither are we."--Jacket.
