摘　　要：水平基因转移(horizontal gene transfer,HGT)是指遗传物质在种间通过非垂直传递方式的移动。HGT可能造成种群的快速协同进化、不同物种间的趋同进化、获得新遗传性状等,是物种进化的重要驱动力之一。过去对HGT的研究主要集中在原核生物和植物方面,但近年来动物方面的HGT现象逐渐受到关注。为进一步了解动物类群中HGT的研究概况,列举了近年来动物类群中HGT的实例和相关证据,评估了证据的可靠性,同时简要介绍了HGT的验证方法,以期更好地理解HGT在动物进化中的重要意义。Horizontal gene transfer （HGT） means the movement of genetic material between species other than via vertical transmission. HGT may cause rapid coevolution in populations, convergent evolution among different species, and inheritance of novel genetic traits, making it one of important driving forces in evolution of species. In the past, HGT studies were mainly focused on prokaryotes and plants, but in recent years, phenomena of HGT in animals gradually attract attention. To further understand current status of research on HGT in animals, examples and relevant evidences of HGT in animal groups are presented, the reliability of the evidence is evaluated, and authentication methods for HGT are briefly described. This may help better understand the significance of HGT in animal evolution.
