Sex and war

Sinopse

Human beings have been battling one another since time immemorial. But why war and terrorism? Why are men almost always the killers, and why are war and sex so inextricably linked? Why do we kill members of our own species intentionally, when few other animals do so? Sex and War traces the cultural and biological evolution of warfare from its prehuman origins through to our own times. In the spirit of Guns, Germs, and Steel, Potts and Hayden pull together insights from history, archaeology, psychology and biology to produce a clarifying new understanding of human history and current events.
