Некоторое время назад, я вышел на связь с Hong Shi и Bing Su. Оказались очень отзывчивые люди. Если есть вопросы к ученым, написавшим известную статью по гаплогруппе О3 - можете задавать вопросы в этой теме.

Abstract

The prehistoric peopling of East Asia by modern humans remains controversial with respect to early population
migrations. Here, we present a systematic sampling and genetic screening of an East Asian–specific Y-chromosome
haplogroup (O3-M122) in 2,332 individuals from diverse East Asian populations. Our results indicate that the
O3-M122 lineage is dominant in East Asian populations, with an average frequency of 44.3%. The microsatellite
data show that the O3-M122 haplotypes in southern East Asia are more diverse than those in northern East Asia,
suggesting a southern origin of the O3-M122 mutation. It was estimated that the early northward migration of
the O3-M122 lineages in East Asia occurred ?25,000–30,000 years ago, consistent with the fossil records of modern
humans in East Asia
