War = the formation of groups to attack others within the same species
More resources (e.g. food) from a bigger territory
More females and more offspring = transfer of genes in to the next generation (the main principle of Darwinian Evolution)
Men evolved as hunter gatherers and women needed protection and therefore women needed to ‘choose’ their mates carefully.
This would suggest that there was at least some advantageous reasoning behind acts of high cost heroic bravery for it to be a characteristic chosen of men by females.
Evolutionary explanations of war
While aggressive display can cost a person their life, by joining a group and taking part in a war there is a greater chance of survival compared to the individual acting alone.
Groups are more powerful and afford more protection, hence war is adaptive.
Success in war can give better access to resources, higher status and ultimately a greater chance of reproducing.
Mass rape as a weapon of war can be accounted for by the evolutionary approach to war: the threat of rape makes people flee their territory, and rape itself may result in the victim becoming pregnant, so the aggressors genes are continuing.
Since those who win wars are the most aggressive, these are the people who have passed on their genes, leading to a species who have had aggression selected into their behaviour
