Male aggression against other males is a common theme of human history. In the US, around 90% of violent crime is committed by males and the vast majority is against other males; the same pattern can be seen around the world. Warfare has always been a male enterprise, and it is easy to see why. Consider Genghis Khan. As the victorious Mongol armies spread throughout Asia, he and his descendants established harems of women and sired large numbers of children. Recent genetic research shows that he now has around 16 million male descendants scattered throughout Asia. Like the invading lion coalition, there was a huge payoff for the winners of war throughout human history.
