Abstract Abstract. A model for the evolution of cooperation shows that two conditions are necessary for cooperation to be stable: a hunting success rate that is low for single hunters and increases with group size, and a social mechanism limiting access to meat by non-hunters. Testing this model on Tai chimpanzees, Pan troglodytes, showed that (1) it pays for individuals to hunt in groups of three or four rather than alone or in pairs, and (2) cooperation is stable because hunters gain more at… 

The meat-scrap hypothesis: small quantities of meat may promote cooperative hunting in wild chimpanzees (Pan troglodytes)

A mathematical model is described demonstrating that group hunting may evolve when individuals can obtain micronutrients more frequently by hunting in groups than by hunting solitarily, provided that group size is below a certain threshold.

“Decision-making” in conflicts of wild chimpanzees (Pan troglodytes): an extension of the Relational Model

Abstract>We examined the “decision-making” process of aggressive interactions within a community of wild chimpanzees (Pan troglodytes verus) in the Taï National Park, Côte d’Ivoire (West Africa).

Longitudinal changes in the targets of chimpanzee (Pan troglodytes) hunts at Mahale Mountains National Park: how and why did they begin to intensively hunt red colobus (Piliocolobus rufomitratus) in the 1980s?

The hunting activities of chimpanzees (Pan troglodytes) at Mahale Mountains National Park exhibited a significant change over a 46-year observation period, shifting from sporadic hunting for small

Cognitive consequences of cooperative breeding? A critical appraisal

It is concluded that there is currently no reason to suppose that cooperative breeding has major cognitive consequences, and there is no compelling evidence that these processes are either unique to cooperative breeders or particularly cognitively demanding.

Two Key Steps in the Evolution of Human Cooperation

Modern theories of the evolution of human cooperation focus mainly on altruism. In contrast, we propose that humans’ species-unique forms of cooperation—as well as their species-unique forms of

Prosocial primates: selfish and unselfish motivations

Observational and experimental evidence is reviewed for the reciprocity mechanisms that underlie cooperation among non-relatives, for inequity aversion as a constraint on cooperation and on the way defection is dealt with.
