Reciprocal altruism is based on the idea of helping others in anticipation of them returning the favor in the future. This requires a stable social group where individuals can interact with each other repeatedly over time. Primates often live in stable social groups, making it possible for them to engage in reciprocal altruism. While primates can recognize kin and have long-term memories, these factors alone are not sufficient to support reciprocal altruism.
