摘要

We present 智能體-based simulations of a model of a deme-structured 族群 in which group differences in 社會 institutions are 文化ly transmitted and individual behaviors are 遺傳ally transmitted. We use a standard extended fitness accounting framework to identify the parameter space for which this co-演化ary process generates high levels of group-beneficial behaviors. We show that intergroup conflicts may explain the 演化ary success of both: (a) altruistic forms of human 社會ity towards unrelated members of one's group; and (b) group-level institutional structures such as food sharing which have emerged and diffused repeatedly in a wide variety of ecologies during the course of human history. Group-beneficial behaviors may evolve if (a) they inflict sufficient fitness costs on outgroup individuals and (b) g
