我们提出了一个来自西伯利亚的尼安德特人妇女的高质量基因组序列。我们发现,她的父母是在同父异母的兄弟姐妹的水平,近亲交配是常见的,她最近的祖先。我们还对来自高加索地区的尼安德特人的基因组进行了测序,覆盖率很低。对现有的古代基因组和25个现代人类基因组的关系和人口历史的分析表明,尼安德特人、丹尼索瓦人和早期现代人之间发生了几次基因流动事件,可能包括从未知的古代群体流入丹尼索瓦人的基因。因此,在更新世晚期,许多人类群体之间发生了杂交,尽管程度很低。此外,高质量的尼安德特人基因组使我们能够建立一个明确的替代清单,这些替代在现代人与尼安德特人和丹尼索瓦人的祖先分离后变得固定。
We present a high-quality genome sequence of a Neandertal woman from Siberia. We show that her parents were related at the level of half siblings and that mating among close relatives was common among her recent ancestors. We also sequenced the genome of a Neandertal from the Caucasus to low coverage. An analysis of the relationships and population history of available archaic genomes and 25 present-day human genomes shows that several gene flow events occurred among Neandertals, Denisovans and early modern humans, possibly including gene flow into Denisovans from an unknown archaic group. Thus, interbreeding, albeit of low magnitude, occurred among many hominin groups in the Late Pleistocene. In addition, the high quality Neandertal genome allows us to establish a definitive list of substitutions that became fixed in modern humans after their separation from the ancestors of Neandertals and Denisovans.
