摘　　要： 大约5～10万年前,现代人走出非洲并迁移至世界各地繁衍生息.在这一历史迁徙过程中,他们面临着各种新环境的生存挑战.随着群体遗传学信息、环境因素和表型资料等的不断累积,越来越多的研究发现环境因素在人类的适应性进化中起着至关重要的作用.本文从自然气候因素、环境中的病原体分布及食物来源等方面对人类的适应性进化进行综述,并对今后的研究进行展望. Archaeological and genetic evidence suggests that anatomically modem humans migrated out of Africa about 50000-100000 years ago and then spread to the rest of world. During this period, they encountered multiple environmental challenges. Progress in the study of human population genetics, along with environmental and phenotypic information, has allowed the identification of many excellent examples of human environmental adaptation. The aim of this review is to provide a brief overview of the advances made by human environmental adaptation studies, especially in relation to climate change, pathogens, and food sources, as well as to outline future research directions.
