Taï Chimpanzee Project (Taï National Park, Côte d'Ivoire) has yielded unprecedented insights into the nature of cooperation, cognition and culture in our closest living relatives. Founded in 1979 by Christophe and Hedwige Boesch, the project has continued for over 40 years. Alongside with other famous long-term chimpanzee study sites at Gombe and Mahale in east Africa, the tireless work of the team at Taï has contributed to the field of behavioural ecology and anthropology as well as improving public awareness of the urgent need to protect this already endangered species. Encompassing important research topics including chimpanzee ecology, reproductive behaviour, tool use, culture, communication, cognition and conservation, this book provides an engaging account of how Taï chimpanzees are adapted to African jungle life and how they have developed unique forms of cooperation with less violence, regular adoptions and complex cultural differences between groups.
