西伯利亚东北部更新世以来的人口历史

哥本哈根大学Eske Willerslev研究组近日取得一项新进展。他们探究了西伯利亚东北部自更新世以来的人口历史。 该项研究成果发表在2019年6月5日出版的《自然》上。

据悉,西伯利亚东北部已经有4万多年的人类居住历史,但对其深厚的人口历史仍知之甚少。
 
课题组人员通过分析34个新发现的古代基因组来研究西伯利亚东北部晚更新世的种群历史。这些基因组可以追溯到3.1万到600年前。课题组人员记录了这一时期复杂的人口动态,包括至少三个主要的迁移事件:在一开始,这里居住的是旧石器时代不为人知的“古北西伯利亚人”,他们与早期的西欧亚狩猎采集者有远亲关系;随后有东亚民族到来,导致了“古代古西伯利亚人”的出现,他们与当代远西伯利亚东北部的群落(如科里亚克民族)以及美洲原住民有着密切的联系;以及全新世其他东亚相关民族的迁徙,该课题组人员称之为“新西伯利亚人”,许多当代西伯利亚人都是他们的后裔。每一次人口扩张都在很大程度上取代了早期的居民,并最终形成了居住在横跨欧亚大陆北部到美洲广大地区的当代人类的镶嵌基因组成。

Abstract: Northeastern Siberia has been inhabited by humans for more than 40,000 years but its deep population history remains poorly understood. Here we investigate the late Pleistocene population history of northeastern Siberia through analyses of 34 newly recovered ancient genomes that date to between 31,000 and 600 years ago. We document complex population dynamics during this period, including at least three major migration events: an initial peopling by a previously unknown Palaeolithic population of ‘Ancient North Siberians’ who are distantly related to early West Eurasian hunter-gatherers; the arrival of East Asian-related peoples, which gave rise to ‘Ancient Palaeo-Siberians’ who are closely related to contemporary communities from far-northeastern Siberia (such as the Koryaks), as well as Native Americans; and a Holocene migration of other East Asian-related peoples, who we name ‘Neo-Siberians’, and from whom many contemporary Siberians are descended. Each of these population expansions largely replaced the earlier inhabitants, and ultimately generated the mosaic genetic make-up of contemporary peoples who inhabit a vast area across northern Eurasia and the Americas.
