中国拥有丰富的本土绵羊（Ovis aries）品种资源，与几个游牧社会的历史运动有关。然而，羊的历史和相关的游牧社会在古代中国仍然知之甚少。在这里，我们研究了中国绵羊的基因组多样性，使用全基因组SNP，线粒体和Y染色体变异在> 1,000个现代样本。人口基因组分析结合考古记录和历史民族人口统计数据揭示了中国绵羊起源、二次扩张和混合的遗传特征，从而揭示了东亚游牧民族的居住模式和早期畜牧业的扩张。中国羊起源于距今5,000 - 5,700年的蒙古高原，并在距今3,000 - 5,700年前随着氐羌人的扩张而扩散到黄河中上游地区。之后，绵羊被推断在距今2,000 - 2,600年前沿着氐羌人从北向西南的迁徙路线到达青藏高原和滇黔桂高原。我们还揭示了随后的两波大尾羊迁移到北方中国，这在很大程度上与12 - 13世纪回族穆斯林的祖先东迁和蒙古人的祖先南迁相对应。此外，我们揭示了盘羊渐渗到国内绵羊，广泛的历史混合国内人口和强大的人工选择的尾巴类型和其他性状的迹象，反映了不同的育种策略，在古代中国游牧社会。
China has a rich resource of native sheep (Ovis aries) breeds associated with historical movements of several nomadic societies. However, the history of sheep and the associated nomadic societies in ancient China remains poorly understood. Here, we studied the genomic diversity of Chinese sheep using genome-wide SNPs, mitochondrial and Y-chromosomal variations in > 1,000 modern samples. Population genomic analyses combined with archeological records and historical ethnic demographics data revealed genetic signatures of the origins, secondary expansions and admixtures, of Chinese sheep thereby revealing the peopling patterns of nomads and the expansion of early pastoralism in East Asia. Originating from the Mongolian Plateau ∼5,000‒5,700 years ago, Chinese sheep were inferred to spread in the upper and middle reaches of the Yellow River ∼3,000‒5,000 years ago following the expansions of the Di-Qiang people. Afterwards, sheep were then inferred to reach the Qinghai-Tibetan and Yunnan-Kweichow plateaus ∼2,000‒2,600 years ago by following the north-to-southwest routes of the Di-Qiang migration. We also unveiled two subsequent waves of migrations of fat-tailed sheep into northern China, which were largely commensurate with the migrations of ancestors of Hui Muslims eastward and Mongols southward during the 12th‒13th centuries. Furthermore, we revealed signs of argali introgression into domestic sheep, extensive historical mixtures among domestic populations and strong artificial selection for tail type and other traits, reflecting various breeding strategies by nomadic societies in ancient China.
