Recently, Japan's national broadcasting corporation, NHK, presented a TV program for the generals, in which the latest findings of anthropology were given. The broadcasting corporation published a book in parallel with the TV program, unfortunately in Japanese.
I'll quote and translate a paragraph from the book, which would be the most critical to the issue.
Quote (translation by me)(at page 34): in [ ] my supplementation:
Mitochondria DNA
In the NHK publication, Dr. Satoshi Horai's research into mitochondria DNA is presented in detail. One section of the mitochondria DNA, called D-loop, consists of 482 characters. Out of the number, 190 characters were available throughout samples. The sample consists of 98 Asians, 10 Africans, 20 Europeans (so far, all samples are from live bodies), 3 Jomon bone sets from Hokkaido (ca. 3000 years ago), two Jomon bone sets from Saitama (ca. 6000 years ago) and 6 Ainu bones (say, 200 years ago).
His findings included:
Gene DNA Another DNA researcher, Keiichi OMOTO, says as follows.
Classic anthropology said Ainu was different from Japanese and many anthropologists said Ainu belonged to the group of white people. However, this theory has been rejected by recent molecular anthropology and others. (end of quote: Original in Japanese: Translation by me.)
I'd let you think about these, rather than solidify an unfounded perception impressed by appearances which would be dangerously subjective.
