Title Ancient mitogenomes show plateau populations from last 5,200 years partially contributed to present-day Tibetans
Relevance Evolution
Data types Assembly
Organisms Homo sapiens
Description The clarification of the genetic origins of present-day Tibetans requires an understanding of their past relationships with the ancient populations of the Tibetan Plateau. Here we successfully sequenced 67 complete mitochondrial (mtDNA) genomes of 5,200 to 300-year-old humans from the plateau. Apart from identifying two ancient plateau lineages (haplogroups D4j1b and M9a1a1c1b1a) that suggest some ancestors of Tibetans came from low-altitude areas 4,750 to 2,775 years ago and that some were involved in an expansion of people moving between high-altitude areas 2,125 to 1,100 years ago, we found limited evidence of recent matrilineal continuity on the plateau. Furthermore, deep learning of the ancient data incorporated into simulation models with an accuracy of 97% supports that present-day Tibetan matrilineal ancestry received partial contribution rather than complete continuity from the plateau populations of the last 5,200 years.
