Although evolutionary theory was proposed before Darwin, he is credited with systematizing it and making it widely accepted. Lamarck’s advances, Darwin’s theory of natural selection, neo-Darwinism, and genetic research have all contributed to the progressive development of evolutionary theory. However, evolutionary theory still faces controversy with creationism, especially the debate...

Altruism in human societies, where selfishness and altruism coexist, is difficult to explain in terms of natural selection, and group selection theory provides a solution. While individual selection favors selfish behavior, group selection favors altruistic groups that cooperate to survive. For example, altruistic groups can cooperate to care for the weak and thus maintain a larger surviving...

To understand why altruistic behavior persists in human societies, the theory of group selection is proposed. Group selection is the hypothesis that natural selection occurs at the group level rather than the individual level, and that altruistic behavior favors the survival of the group. Despite the fact that altruistic behavior is to the detriment of the individual, the transmission of...
