"We don't see sexual coercion in bonobos, which is a common phenomenon in chimpanzees," said Surbeck. Intriguingly, females, both within and from different groups, were found to form coalitions - sometimes to chase an individual from a feeding tree, at other times to prevent a coercive sexual advance from a male. The positive interactions occurred despite a low level of genetic relatedness between the groups, and despite the fact that reciprocity - such as paying back a gift of fruit - often took place much later, in future encounters. These individuals tended to connect with similar "pro-social" bonobos from the other group, creating a system of mutual benefit, or "reciprocal altruism." The team found that cooperation between the groups was driven largely by a select few who were more helpful within their own group. "There are those that are more introverts, extroverts, there are those that are more pro-social than others." "Every individual is different," said Samuni. Samuni and Surbeck focused on two small bonobo groups of 11 and 20 adults respectively, and found to their surprise they spent 20% of their total time together - feeding, resting, traveling and more. is try to run away from you," Surbeck told AFP, explaining it took a long time for the bonobos to overcome their inherent fears of humans and behave normally.ĭays began at 4am and involved researchers trekking through the dark forest until they reached bonobo nests, then waiting for sunrise so they could follow the apes throughout the day, aided by indigenous Mongandu trackers. In the new paper, Samuni teamed up with Martin Surbeck, a professor at Harvard who founded the Kokolopori Bonobo Reserve, to carry out a long-term study over two years. Female coalitions against sexual aggression. With research on chimps dominating the literature, some scientists assumed hostility against outsiders was innate to human nature - something we had perhaps trained ourselves to get past by inventing new social norms, even as that trait lurked deep inside. That's because bonobos, an endangered species, are notoriously difficult to study in their natural habitat - and they live only in remote regions of the Democratic Republic of the Congo. Lead author Liran Samuni of the German Primate Center in Gottingen told AFP that studying the primates offered a "window into our past," possibly signaling an evolutionary basis for how our own species began wider-scale collaborative endeavors.īonobos (Pan paniscus) are our closest living relatives, alongside chimpanzees (Pan troglodytes), and the two species are also very closely related to each other.īut while encounters between chimpanzee groups are inherently hostile and often result in lethal violence, interactions between bonobo parties had not been as well examined. WASHINGTON - Human society is founded on our ability to cooperate with others beyond our immediate family and social groups.Īnd according to a study published Thursday in the journal Science, we are not alone: bonobos team up with outsiders too, in everything from grooming to food sharing, even forming alliances against sexual aggressors.
