Bonobos offer insight into evolution of cooperation — Harvard Gazette

November 19, 2023

It turns out that one of our closest living relatives, bonobos, are also able to think outside the group. The ability to engage in such “out-group” cooperation is the foundation on which humans have created societies and cultures through trade and knowledge-sharing. The study was published in Science with lead author Liran Samuni, a former Harvard research associate who works at the German Primate Center in Göttingen. These certain few consistently engaged in behaviors such as grooming and food-sharing and acted as links between groups — think ape ambassadors. Within each behavior, individuals cooperated with specific counterparts who were also good cooperators in that domain.
