5. Evolutionary explanations
of War
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
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 group display is adaptive
Success in war can give better access to resources, higher status and ultimately a greater chance of reproducing
