For example, up to 90% of Ainu paternal DNA belong to Y-haplogroup D, while only 50% of Japanese paternal DNA do. Ainu also have a significant - up to 20% - of mtDNA Y, which among Japanese reaches only 1-2%.

Their distribution is quite similar to that of Tibetans, with similar percentages of D and O, 45% and 30%, respectively. But importantly, they have up to 17% of R1a, J, and F. Their mtDNA is largely shared with lowland East Asians, but also contain a few distant clades such as M5c2, M21d, and U.

It cannot be used to argue about the Neolithic and/or Paleolithic migrations that shaped the plateau. The fact that Y-DNA D is so plentiful among both Tibetans and Sherpa must be explained, as it is a generally rare haplogroup in low-land populations as well as populations to the north that might've migrated into the plateau.
