Intraspecific coalitional aggression between groups of individuals is a widespread trait in the animal world. It happens in invertebrates and vertebrates, and is prevalent in humans. What are the circumstances under which coalitional aggression evolves in natural populations? In this article, I develop a mathematical model delineating situations where natural choice can favor the coevolution of belligerence and bravery between small-scale societies. Belligerence increases an actor’s group probability of attempting to conquer one other group and bravery enhance the actors’s group chance of defeating an attacked group.

The mannequin takes into consideration two several types of demographic eventualities that will lead to the coevolution of belligerence and bravery. Under the first, the fitness benefits driving the coevolution of belligerence and bravery come by way of the repopulation of defeated teams by fission of victorious ones. Under the second demographic scenario, the fitness benefits come through a short lived improve in the local carrying capacity of victorious groups, after transfer of assets from defeated teams to victorious ones. The evaluation of the mannequin means that the selective pressures on belligerence and bravery are stronger when defeated teams might be repopulated by victorious ones. The evaluation also means that, depending on the form of the competition success function, pricey bravery can evolve in teams of any dimension.
