Evolution and Group Behavior: Individual and Group Selection

摘要: Author(s): Bergstrom, Ted | Abstract: How selfish does our evolutionary history suggest that humans will be? We explore models in which groups are formed and dissolved where reproduction of individuals is determined by their payoffs a game played within groups. If ``randomly'' reproductive success group founders multi-person prisoners' dilemma game, then behavior prevail over maximization payoffs. However, interesting exist ``group selection'' sustains cooperative behavior. Forces support include assortative matching groups, longevity, punishment-based norms.
