A）阶段1 Period I（45~19 kaBP）；B）阶段2 Period II（19~10 kaBP）：AE，以Kostenki 14为代表的古欧洲人群相关的遗传成分ancestry related to Ancient Europeans (represent by Kostenki 14)；BE，与未经取样的古欧亚人群相关且在现今欧洲人群、部分古代和现今中东人群中可找到的遗传成分ancestry related to an unsampled population known as Basal Eurasians and found in small numbers in ancient and present-day populations of the Near East and in present-day Europeans；ANS，以Yana为代表的古西伯利亚北部人群相关的遗传成分ancestry related to ancient North Siberians (represent by Yana); ANE, ancestry related to ancient North Eurasians (represent by Mal’ta-1 and Afontova Gora-3)；ANE，以Mal’ta-1和Afontova Gora-3为代表的古北欧亚人群相关的遗传成分；BEA，以田园洞人和AR33K为代表的基础东亚人相关的遗传成分；BA，以La368为代表的古代东南亚狩猎采集人群相关祖源成分；AEA，东亚古北方人群和东亚古南方人群分离前的亚洲人群；ANEA，以AR14K、扁扁洞、Devil’s Gate等个体为代表的东亚古北方人群；ASEA，以奇和洞、亮岛个体为代表的东亚古南方人群；AGX，以隆林个体为代表的古广西人群。图1A中的紫色代表田园洞人和Goyet Q116-1个体相联系的成分。虚线区域是指该遗传成分源自根据遗传数据所推测的人群状态，但未发现这一时期的古代样本。各颜色大致显示为某代表区域之间或之内的遗传成分组合，且颜色梯度显示为不同人群之间可能存在的遗传联系（如基因流）。

Fig.1. Schematic of Populations in Eurasia from 45 to 10 kaBP
AE, ; BE, ; ANS, ; BEA, ancestry related to Basal East Asians (represent by Tianyuan and AR33K); BA, ancestry related to Basal Asians (represented by La368); AEA, ancestry related to Ancient East Asians; ANEA, ancestry related to Ancient Northern East Asians (represented by AR14K, Bianbian, Devil’s Gate, etc); ASEA, ancestry related to Ancient Southern East Asians (represented by Qihe and Liangdao); AGX, ancestry related to Ancient Guangxi population (represented by Longlin). The purple color in Fig.1A shows the connection between Tianyuan and Goyet Q116-1. Broken lines indicate no ancient genetic samples have been found for a population with the inferred ancestry. Colors loosely indicate genetic groupings between or within a region, with color gradients showing the connections (i.e., gene flow) that may exist between different ancient populations.
