现代人类到达东亚的时间和性质以及随后向东亚的扩张仍然存在争议。利用 Y 染色体双等位标记，我们研究了东亚古代人类迁徙模式。我们的数据表明，东亚南部人群的多态性比北部人群高得多，后者仅具有南部单倍型的一个子集。这一模式表明，现代人类在东亚的首次定居发生在最后一个冰河时期的东南亚大陆，恰逢5万至10万年前东亚地区没有人类化石。在最初的人口出现之后，大规模的北迁延伸到了中国北部和西伯利亚。
The timing and nature of the arrival and the subsequent expansion of modern humans into eastern Asia remains controversial. Using Y-chromosome biallelic markers, we investigated the ancient human-migration patterns in eastern Asia. Our data indicate that southern populations in eastern Asia are much more polymorphic than northern populations, which have only a subset of the southern haplotypes. This pattern indicates that the first settlement of modern humans in eastern Asia occurred in mainland Southeast Asia during the last Ice Age, coinciding with the absence of human fossils in eastern Asia, 50,000-100,000 years ago. After the initial peopling, a great northward migration extended into northern China and Siberia.
