Closely related species
Studies on communicative skills of very closely related species (humans – great apes) enable us to draw inferences about the evolutionary origins of human language.
Bonobos (Pan paniscus)
Our studies on bonobos take place at two field stations in the Democratic Republic of Congo (DRC):
(1) Lui Kotal, Salonga National Park (in cooperation with Dr. B. Fruth and Dr. G. Hohmann, Max Planck Institute for Evolutionary Anthropology, Germany), and
(2) Wamba, Luo Scientific Reserve (in cooperation with Prof. T. Furuichi, Kyoto University, Japan).
Chimpanzees (Pan troglodytes)
We observe the communicative behaviour of chimpanzees at three field stations in Uganda and the Ivory Coast in Africa:
(1) Kanyawara, Kibale National Park, Uganda (in cooperation with Dr. M. Muller, University of New Mexico, USA and Prof. R. Wrangham, Harvard University, USA),
(2) Ngogo, Kibale National Park, Uganda (in cooperation with Prof. J. Mitani, University of Michigan, USA and Prof. D. Watts, Yale University, USA), and
(3) Taï, Taï National Park, Ivory Coast (in cooperation with Dr. R. Wittig and Prof. C. Boesch, Max Planck Institute for Evolutionary Anthropology, Germany).
