这项研究为文化规范发展和维持的进化基础提供了新的见解。我们产生的证据之间的生态威胁，等位基因频率的5-羟色胺转运体多态性（5-HTTLPR），文化的紧松规范和容忍偏离规范的力量和道德的可接受性一个独特的文化基因的共同进化模型。根据假设，21个国家的结果显示：（a）生态威胁倾向与5-HTTLPR中的短（S）等位基因频率相关，（B）5-HTTLPR中的等位基因频率和对生态威胁的脆弱性都与文化紧-松相关，（c）对生态威胁的易感性通过S等位基因携带者的介导预测紧-松，（d）S等位基因携带者的频率通过紧-松预测道德相关行为的可验证性。这项研究强调了研究当代社会行为差异背后的环境、遗传和文化因素之间相互作用的重要性，并为未来的研究提供了一个实证框架。本文的在线版本（doi：10.1007/s40167-013-0009-x）包含补充材料，可供授权用户使用。
This research provides novel insights into the evolutionary basis of cultural norm development and maintenance. We yield evidence for a unique culture–gene coevolutionary model between ecological threat, allelic frequency of the serotonin transporter polymorphism (5-HTTLPR), cultural tightness–looseness—the strength of norms and tolerance for deviance from norms—and moral justifiability. As hypothesized, the results across 21 nations show that: (a) propensity for ecological threat correlates with short (S) allele frequency in the 5-HTTLPR, (b) allelic frequency in the 5-HTTLPR and vulnerability to ecological threat both correlate with cultural tightness–looseness, (c) susceptibility to ecological threat predicts tightness–looseness via the mediation of S allele carriers, and (d) frequency of S allele carriers predicts justifiability of morally relevant behavior via tightness–looseness. This research highlights the importance of studying the interplay between environmental, genetic, and cultural factors underlying contemporary differences in social behavior and presents an empirical framework for future research.
