Great apes communicate cooperatively

Human language is a fundamentally cooperative enterprise, embodying fast-paced interactions. It has been suggested that it evolved as part of a larger adaptation of humans’ unique forms of cooperation. In a cross-species comparison of bonobos and chimpanzees, scientists from the Humboldt Research Group of the Max Planck Institute for Ornithology in Seewiesen now showed that communicative exchanges of our closest living relatives, the great apes resemble cooperative turn-taking sequences in human conversation.

Human communication is one of the most sophisticated signalling systems, being highly cooperative and including fast interactions. The first step into this collective endeavour can already be observed in early infancy, well before the use of first words, when children start to engage in turn-taking interactional practices embodying gestures to communicate with other individuals. One of the predominant theories of language evolution thus suggested that the first fundamental steps towards human communication were gestures alone.

The research team of Marlen Fröhlich and Simone Pika of the Humboldt Research Group at the Max Planck Institute for Ornithology together with colleagues from the Max Planck Institute for Evolutionary Anthropology in Leipzig, the Ludwig- Maximilians-University in Munich and the Kyoto University in Japan, conducted the first systematic comparison of communicative interactions in mother-infant dyads of two different bonobo and two different chimpanzee communities in their natural environments.

The bonobos were studied over the duration of two years in the Salonga National Park and Luo Scientific Reserve in the Democratic Rebublic of Congo. The chimpanzees were observed in the Taï National Park, Côte D’Ivoire, and Kibale National Park in Uganda.

The results showed that communicative exchanges in both species resemble cooperative turn-taking sequences in human conversation. However, bonobos and chimpanzees differ in their communication styles. “For bonobos, gaze plays a more important role and they seem to anticipate signals before they have been fully articulated” says Marlen Froehlich, first author of the study.

In contrast, chimpanzees engage in more time-consuming communicative negotiations and use clearly recognizable units such as signal, pause and response. Bonobos may therefore represent the most representative model for understanding the prerequisites of human communication. “Communicative interactions of great apes thus show the hallmarks of human social action during conversation and suggest that cooperative communication arose as a way of coordinating collaborative activities more efficiently,” says Simone Pika, head of the study.
