한국인DNA, 열본 열도를 개척

it has not been found at all among a total of twenty Ainu males whose Y-DNA has been sampled in two genetic studies.[8][19]

02b는 일본 전통의 열도 아이누인 에게서는 발견되지 않는다

Based on the STR haplotype diversity within Haplogroup O2b1,
it has been estimated that this haplogroup began to experience a population expansion among the proto-Japanese o approximately 4,000 years ago, which makes it a good candidate for a marker of the intrusion of a Neolithic population of the prehistoric Korean Peninsula into the southwestern parts of the Japanese Archipelago.

02b1의 경우 4000년전 일본 열도에 확장된 것으로 보인다
이러한 결과는 이 시기 한반도 도래인이 일본 남서부로 유입되다는 좋은 증거이다

However, the parent haplogroup, O2b*, is also found among Japanese, although at a relatively low frequency of approximately 4%[14] to 8%[9], and the descendant haplogroup O2b1 is found only with low frequency among samples of modern Koreans, which suggests the possibility that Haplogroup O2b* might have colonized the Japanese Archipelago much earlier, with the subgroup O2b1 subsequently evolving within the proto-Japanese-Ryukyuan population of the western parts of the archipelago.
