目的探讨O 1a-M119的起源、变异和1万年来的人口统计学历史，以及它在东亚和东南亚人群，特别是汉族、台语和南岛语人群形成中的作用。包括本研究中新产生的17个，被用来重建一个修订的系统发育树与年龄估计，并确定亚谱系。结果修订的系统发育树、年龄估计和分布图显示，O 1a-M119单倍群在过去的1万年中不断扩展，不同地理区域的人口统计学历史存在差异。我们提出了几个亚系的O 1a-M119作为创始父系血统的汉族，台语，南岛语的人口。这三个人群之间共享了几个年轻的O 1a-M119亚系，其扩张时间小于6000年，支持它们在新石器时代的部分共同祖先;然而，父系遗传分化模式比以前基于人种学，考古学，讨论我们的分析有助于更好地了解过去10，000年来在汉族，南岛语族，说台语的人本研究所提供的资料，将有助于未来从民族学、考古学、语言学的角度，了解汉族、台语、南岛语族群的历史。
Objectives The aim of this research was to explore the origin, diversification, and demographic history of O1a-M119 over the past 10,000 years, as well as its role during the formation of East Asian and Southeast Asian populations, particularly the Han, Tai-Kadai-speaking, and Austronesian-speaking populations.Materials and Methods Y-chromosome sequences (n = 141) of the O1a-M119 lineage, including 17 newly generated in this study, were used to reconstruct a revised phylogenetic tree with age estimates, and identify sub-lineages. The geographic distribution of 12 O1a-M119 sub-lineages was summarized, based on 7325 O1a-M119 individuals identified among 60,009 Chinese males.Results A revised phylogenetic tree, age estimation, and distribution maps indicated continuous expansion of haplogroup O1a-M119 over the past 10,000 years, and differences in demographic history across geographic regions. We propose several sub-lineages of O1a-M119 as founding paternal lineages of Han, Tai-Kadai-speaking, and Austronesian-speaking populations. The sharing of several young O1a-M119 sub-lineages with expansion times less than 6000 years between these three population groups supports a partial common ancestry for them in the Neolithic Age; however, the paternal genetic divergence pattern is much more complex than previous hypotheses based on ethnology, archeology, and linguistics.Discussion Our analyses contribute to a better understanding of the demographic history of O1a-M119 sub-lineages over the past 10,000 years during the emergence of Han, Austronesians, Tai-Kadai-speaking populations. The data described in this study will assist in understanding of the history of Han, Tai-Kadai-speaking, and Austronesian-speaking populations from ethnology, archeology, and linguistic perspectives in the future.
