摘　　要：灵长类动物的社会组织形式呈现出极高的多样性,但其演化历程,特别是几种最复杂的社会组织的起源尚未得到阐明。近百年来,为回答该问题,社会生态学和行为学领域已经积累了丰富的资料,提出了众多理论,但它们主要停留在宏观层面,缺乏对基因组等微观机制的阐述。近日发表于《科学》的一项工作中,由西北大学齐晓光教授等中外科学家组成的联合团队,聚焦于独特珍稀的亚洲叶猴类,综合了来自比较基因组学、生态学、古生物学、行为学、细胞生物学等多领域的证据,全面地还原了该类群的自然史,尝试回答什么是社会组织演化的驱动因素。结果显示,亚洲叶猴类的社会组织具有很强的系统发育信号,且受到历史上环境事件的深刻影响。其中,群体的复杂化可能与寒冷驱动的多巴胺通路和催产素通路的快速演化有关。该研究开创了“行为-生态-基因组”综合分析的范式,为灵长类社会演化研究领域开辟了新的道路。The social systems of primates are highly diverse,but their evolutionary history,especially the origin of some most complex societies,remains elusive.Although much attention has been focused on this issue for about one century and tremendous progress has been made in thefields of social ecology and ethology,we still know little about the genetic underpinnings of primates’social behaviors.Recently,a joint team of Chinese and foreign scientists,led by Professor Qi Xiaoguang of Northwest University,has provided new insights into this question with evidence from comparative genomics,ecology,paleontology,ethology,and cell biology.This work has been published in Science.They focused on the natural history of Asian colobines,a group of unique and endangered Old World monkeys,and discovered the possible driving force of their social evolution.The results demonstrated that this taxon’s social systems both have a strong phylogenetic signal and were deeply affected by historical environmental events.Rapid evolution and reorganization of dopamine and oxytocin pathways driven by cold climate may play a key role in the formation of the most complex multi-level societies.This study has pioneered a“behavior-ecology-genome”paradigm,opening up a new avenue for the study of primate social evolution.
