Using genome-wide data of 89 ancient individuals dated to 5100 100 years before the present (B.P.) from 29 sites across Tibetan Plateau, we found plateau-specific ancestry plateau populations, with substantial genetic structure indicating high differentiation 2500 B.P. Northeastern populations rapidly showed admixture associated millet farmers by 4700 in Gonghe Basin. High similarity on southern and southwestern population expansion along Yarlung Tsangpo River since 3400 ago. Central...
The extreme environments of the Tibetan Plateau offer considerable challenges to human survival, demanding novel adaptations. While role biological and agricultural adaptations in enabling early colonization plateau has been widely discussed, contribution pastoralism is less well understood, especially dairy that historically central diets. Here, we analyze ancient proteins from dental calculus (n = 40) all individuals with sufficient preservation interior plateau. Our paleoproteomic results...
The settlement of the Tibetan Plateau epitomizes human adaptation to a high-altitude environment that poses great challenges activity. Here, we reconstruct 4000-year maternal genetic history Tibetans using 128 ancient mitochondrial genome data from 37 sites in Tibet. phylogeny haplotypes M9a1a, M9a1b, D4g2, G2a'c, and D4i show share most recent common ancestor with Middle Upper Yellow River populations around Early Holocene. In addition, connections between Northeastern Asians vary over past...
The clarification of the genetic origins present-day Tibetans requires an understanding their past relationships with ancient populations Tibetan Plateau. Here we successfully sequenced 67 complete mitochondrial DNA genomes 5200 to 300-year-old humans from plateau. Apart identifying two plateau lineages (haplogroups D4j1b and M9a1a1c1b1a) that suggest some ancestors came low-altitude areas 4750 2775 years ago were involved in expansion people moving between high-altitude 2125 1100 ago, found...
The Qinghai-Tibet Plateau (QTP) has become a valuable site for investigation of adaptive regimes prehistoric humans to extreme environments. At present most studies have focused solely on single site. Using more integrated approach that covers the complete scope plateau is needed better understand expansion logic moving towards plateau. Here, we conducted accelerator mass spectrometry
Southwest China is vital for understanding the dispersal and development of farming because coexistence millet rice in this region since Neolithic. However, process Neolithic transition southwest largely unknown due to lack ancient DNA from period. Here we report genome-wide data 11 human samples Gaoshancheng Haimenkou sites with mixed dating between 4500 3000 years before present China. The two groups derived about 90% their ancestry Yellow River farmers, suggesting a demic diffusion Their...
