摘　　要：在现代人的起源过程中,某些已灭绝的古人类对现代人的基因组曾有过遗传贡献.丹尼索瓦人是著名的已灭绝古人类尼安德特人的姐妹群,也是现代人已灭绝的近亲分支之一.他们在(30~3)万a前生活在西伯利亚到东亚、东南亚的广阔区域,其面部形态与尼安德特人相似,但颌骨更宽,也更突出.基因组分析表明,当今很多地区的现代人携带不同比例的丹尼索瓦人基因,有些基因还对现代人的环境适应能力产生了积极影响.During the origin of modern humans, certain extinct archaic hominin groups made genetic contributions to the genome of modern humans.Denisovans are the sister group of Neanderthals, another extinct hominin, which were one of the close but extinct relatives of modern humans.They lived in a wide area from Siberia to East Asia and Southeast Asia during(300~30)ka.Their facial morphology shares more similarity with that of Neanderthals, but their jaws are wider and more protruding.Genomic analysis suggests that modern humans in many areas today carry genes from Denisovans in different proportions, some of which have a positive impact on the environmental adaptability of modern humans.
