Question

Quizplus · Accepted Answer

The statement that reciprocal altruism exists among primates because they often live in stable social groups is supported by research. Primates, such as vervet monkeys and chimpanzees, have been observed engaging in behaviors that can be explained by reciprocal altruism, such as grooming each other or sharing food. These behaviors are more likely to occur within stable social groups where individuals have repeated interactions and the opportunity for future exchanges of favors. Kin recognition and long-term memory are important factors in the evolution of reciprocal altruism, but they are not the only factors. The diverse diet of primates is not directly related to the existence of reciprocal altruism.
