The genetic history of Southern East Asians is not well-known, especially prior to the Neolithic period. To address this, we successfully sequenced two complete mitochondrial genomes of 11,000-year-old human individuals from Southern China, thus generating the oldest ancient DNA sequences from this area. Integrating published mitochondrial genomes, we characterized M71d, a new subhaplogroup of haplogroup M71. Our results suggest a possible early migration between Southern China and mainland Southeast Asia by at least 22,000 BP.
东亚南部人群的遗传历史并不为人所知，尤其是在新石器时代之前。为了解决这一问题，我们成功地对来自中国南部的两个 11000 年前的人类个体进行了全基因组测序，从而获得了该地区最古老的古 DNA 序列。整合已发表的线粒体基因组数据，我们鉴定了 M71d，这是 M71 单倍群下的一个新的亚单倍群。我们的研究结果表明，早在 22000 年前，东亚南部人群和东南亚大陆之间可能就已经存在早期的迁徙。
