Exploring Warfare and Violence from a Cross-Cultural Perspective : Introduction to the Special Issue.

This special issue of Human Nature presents selected works from the 2015 and 2017 "Warfare, Environment, Social Inequality, and Pro-Sociability" (WESIPS) conferences held at the Center for Cross-Cultural Study in Seville, Spain. These investigations explore the manifestations of indigenous warfare and violence from a host of theoretical perspectives. Topics range from the origins of warfare to the psychological repercussions of combat, the relationship between warfare and status, as well as the documentation of peace processes among warring groups. This issue also examines the effects of militarization and coercive conservation on indigenous peoples.
