Bonobos willingly share food with strangers in exchange for company
Bonobos voluntarily share food and even renounce its own food by a stranger, but only if the receiver offers to change social interaction, according to a study published this Wednesday by Jingzhi Tan and Brian Hare, the Duke University (United States), in the magazine 'Plos One'.
In a series of experiments, the authors found that the behaviour of bonobos was at least partly driven by altruistic motivations, Since the animals helped buy food to strangers, even without the possible social interaction as a result of helping them. But, his generosity had its limits: animals do not share food in their possession if there is no social interaction possible.
Although the study subjects were all bonobos orphaned by the bushmeat trade in the Congo, showed no significant psychological differences from bonobos that had been raised by their mothers. According to the researchers, their results highlight the evolution of the generosity of these apes, the closest relatives of humans, and suggest that the behavior may have evolved to allow for expansion of the various social networks.
