Also known as altruistic behavior. Behavior that benefits other individuals without considering any disadvantage to oneself. Typical examples are the raising of young and helper behavior by workers of social insects (ant and bee workers). When altruistic behavior is exchanged between individuals, such as grooming, it is called reciprocal altruism. The evolution of altruistic behavior is generally explained by the kin selection theory. → Related topics Inclusive fitness | Selfish genes Source : Heibonsha Encyclopedia About MyPedia Information |
