The Anthropocene extinction is an existential threat to chimpanzee and bonobo populations. 
This PhD aims to examine the impacts the Anthropocene extinction is having on parochial altruism in great apes, with particular attention paid to the increased risk  
Ultimately hoping to explain how climate crises drive intergroup conflict, the impact of resource limitation on intra-group cohesion and explore the limits of parochial altruism under extreme environmental conditions.
