What does modern warfare, as fought by liberal societies, have in common with our human evolution? This study posits an important relationship between the two - we have evolved to fight, and traditional hunter-gatherer societies were often violent places. But we also evolved to cooperate, to feel empathy and to behave altruistically towards others.
