Male chimpanzees compete intensely with each other over food, status and females. However, they also form coalitions, hunt in groups, share food and jointly defend their territory against neighboring chimpanzee communities. How do they achieve this balance between competition and cooperation? Why cooperate if Natural Selection favors those who act in their own self-interest? Join us for a discussion of these and other fascinating topics with Ian Gilby, chimpanzee expert and co-director of the Jane Goodall Institute Research Center at Duke University.
