A new study has looked into how our psychology concerning war and conflict may have been shaped by our evolutionary past. Following a review of current academic literature by psychologists, biologists and anthropologists, the study concludes that men are biologically programmed to be warriors because of our deep ancestral history of inter-tribal war and conflict. Meanwhile, females have evolved a response to threats from male outsiders where they ‘tend and befriend’ as a way of protecting their offspring, suggests the study.
