摘要: Abstract Understanding the evolution of parochial altruism is great importance. We here institute an analytical model to study emergence in group-structured populations. Individuals' strategy contingent on interacting partners' group property. Only when sharing common tag(s), they play prisoner's dilemma game; otherwise punishment game. The conditions for are specified weak selection. Emergence promoted by assortment as well intergroup punishment. Furthermore, affiliation plays a negative (positive) role low (high) mutation.
