This thesis broadly investigates the evolution of voluntary cooperative behaviour among individuals in conflict in non-egalitarian social groups. This work is partitioned into three sections. In the first section, we explore the emergence of non-egalitarian social groups to better understand the evolutionary incentives for voluntary participation in groups with unequal distributions of resources. In the second section, we study several scenarios in which genetically related individuals with unequal control over resources cooperate despite being in conflict. The evolution of parent-offspring conflict over provisioning, offspring signals, and alloparental care are each addressed in this section. In the last section, we investigate cooperative behaviours between unrelated individuals in conflict by modelling the evolution of coalitionary behaviour.
