Male sex drive ‘to blame for virtually all conflict’

Male sex drive is at the root of most conflict in the world, from football violence to world wars, scientists have claimed.

A review of psychological evidence concludes that men are shaped by evolution to be aggressive towards “outsiders”. The tendency, at the heart of all inter-tribal violence, emerged through natural selection as a result of competition for mates.

Today it can be seen in large-scale conflicts between nations as well as clashes involving rival gangs, football fans or religious groups, say the researchers.

Women, on the other hand, are said to have been programmed by natural selection to “tend and befriend” to protect their offspring.
