Study reveals that female chimpanzees team up to retaliate against male aggression

Study reveals that female chimpanzees team up to retaliate against male aggression: "Also, the absence of similar reports from wild populations suggests that females may be able to form coalitions only under appropriate conditions – such as ecology, demography or local tradition. If groups of females are able to spend time together because of the way food is distributed in the habitat, then they are ‘on-hand’ to provide support and form coalitions. Whether they do this simply because they are present when another female is threatened by a male, or because they have previously formed a supportive relationship, are questions for future research.’ "
