Evolutionary roots of aggression from "summary" of Evolutionary Psychology by David Buss
Aggression is a universal behavior that has deep evolutionary roots. It is not unique to humans; rather, it can be observed in many species as a means of survival and reproduction. In the animal kingdom, aggression serves as a tool for obtaining resources, defending territory, and securing mates. This primal instinct has been shaped by millions of years of evolution, as individuals who were better able to assert themselves in competitive environments were more likely to pass on their genes to future generations.

One key factor is the concept of intrasexual competition, where individuals compete with members of the same sex for access to mates.
