Abstract:

The Ainu people are assumed to be the descendants of pre-agricultural native populations of northern Japan, while the majority of population of present-day Japan (Hondo-Japanese) is considered to have descended mainly from post-neolithic migrants. Sequence-level polymorphisms of the HLA-class I (HLA-A and HLA-B) genes were investigated in DNA samples of 50 Ainu living in Hidaka district, Hokkaido. HLA-A*2402, A*0201, A*0206, A*2601, A*3101, B*1501, B*5101, B*3901, and B*3501 were observed at frequencies of more than 10% and most of these have previously been found in populations of not only Asians but also North and South American Indians. A*68012, which has not so far been detected in Hondo-Japanese, was found in the Ainu (3%). On the other hand, several alleles common in Hondo-Japanese, including HLA-A*3303, A*1101, B*4403, B*5201, B*5401, B*4601, and B*0702 were infrequent in Ainu (0-1%). Correspondence and neighbor-joining analyses of various populations based on HLA-A, -B and -DRB1 gene frequencies enabled distinction between Asian, Native South American, European, and African populations. The Ainu, as well as Tlingit (Na-Dene), were placed midway between other East Asians, including Hondo Japanese, and Native South Americans (Amerindians) in the correspondence analysis. Furthermore, several HLA-A-B and HLA-B-DR-DQ haplotypes common in the Ainu, are shared with some Native American populations. These observations strongly suggest a unique place for the Ainu as descendants of some Upper Paleolithic populations of East Asia, from whom some Native Americans may have descended.

Interesting. I had similar ideas about Ainus.

Ainu are hairy with wavy hairs: it is enough to refer them
as originally non-mongoloid. Some authors relate them with
australoids.

Japan has a high percentage of the Negritid paternal haplogroup IV.

What is negritid?
Anyway negrids are not hairy. Even on the bushmens
totally lack any beard and moustaches.

Negritids are pygmies from tropical Asia, which have been placed within the Australoids. (And, Negritids did contribute to New Guinea.)

Ainu have genetic and physical links to South Seas populations, but theyre also Upper Paleolithic North-East Asians (from the same origin as Europeans).

They aren't the only pre-Neomongoloid people in North-East Asia.
