These mechanisms are purported to have developed as the result of an ancestral history that was largely influenced by frequent and violent intergroup conflict among males, in which success increased their reproductive fitness.

Introduction

Due to reproductive and survival benefits, humans (and other species) tend to come together in groups (Baumeister and Leary 1995). Although costly, intergroup conflict is, and has been, pervasive among humans (Bowles 2009). When these conflicts involve acts of aggression and violence, research finds...
