Definition
Lethal raiding is a form of coalitionary, intergroup aggression observed in chimpanzees in which a party leaves its core range to find and attempt to kill strongly outnumbered and isolated members of neighboring communities.
Introduction
While intergroup conflict is common in social animals, fatal aggression is rare and usually a result of accidental injury during escalated fights (Manson and Wrangham 1991). However, in some species, such as chimpanzees and humans, intergroup aggression appears to be marked by coalitionary, apparently deliberate attempts to kill conspecifics. In chimpanzees, this behavior is likely facilitated by their fission-fusion dynamics, male philopatry, and resource defense polygynandry. We review several proposed hypotheses on the adaptive function of this behavior,...
