CARTA: Male Aggression and Violence in Human Evolution – Anne Pusey: Intergroup Violence: Chimpanzees and Lions

In both lions and chimpanzees, males cooperate in inter-group conflict with group-mates who are often relatives and with whom they maintain close, life-long social bonds. Anne Pusey (Duke Univ) discusses some of the mounting evidence that successful intergroup aggression and killing results in better resources for group members in both species.
