Hamilton's inclusive fitness theory
WebMar 12, 2010 · Hamilton’s theory of inclusive fitness showed how natural selection could lead to behaviors that decrease the relative fitness of the actor and also either benefit (altruism) or harm (spite) other individuals. However, several fundamental issues in the evolution of altruism and spite have remained contentious. Here, we show how recent … WebJan 2, 2024 · Fig. 1.
