Chimpanzees are less likely to steal food from their friends compared to non-friends, as shown in a recent study published in Evolution and Human Behavior. Victims of food theft by friends displayed less emotional distress and calmed down more quickly compared to victims of theft by non-friends, according to researchers at the Ngamba Island Chimpanzee Sanctuary. The study suggests that chimpanzees exhibit relation-specific intentions and mutual expectations in friendships, which may provide insight into the evolutionary roots of human friendships and moral principles.
