Aggressive interactions between two or multiple conspecifics from different social groups in primate species usually lead to the death of at least one of the contenders and to fitness advantages to victors.


Observations of between-group aggression and killing exist for a wide range of primate and nonprimate mammals. Such phenomena occur in different forms, such as coalitional efforts, or independent and individual attacks (i.e., dyadic aggression), and targets may be individuals of any age. This entry will review the current literature on lethal intergroup aggression in nonhuman primates, describing evidences of adaptive value for aggressive interactions and especially killing between groups, in contrast to hypotheses that rely on the concepts of environmental mismatch, trait neutrality, or maladaptation to explain such phenomena. Even though this...
