It seems the Jomon have contributed a lot on Japanese DNA.Will this change the views on Japanese history and DNA?

Paleolithic Contingent in Modern Japanese: Estimation and Inference using Genome-wide Data

Yungang He et al.

The genetic origins of Japanese populations have been controversial. Upper Paleolithic Japanese, i.e. Jomon, developed independently in Japanese islands for more than 10,000 years until the isolation was ended with the influxes of continental immigrants about 2,000 years ago. However, the knowledge of origin of Jomon and its contribution to the genetic pool of contemporary Japanese is still limited, albeit the extensive studies using mtDNA and Y chromosomes. In this report, we aimed to infer the origin of Jomon and to estimate its contribution to Japanese by fitting an admixture model with missing data from Jomon to a genome-wide data from 94 worldwide populations. Our results showed that the genetic contributions of Jomon, the Paleolithic contingent in Japanese, are 54.3∼62.3% in Ryukyuans and 23.1∼39.5% in mainland Japanese, respectively. Utilizing inferred allele frequencies of the Jomon population, we further showed the Paleolithic contingent in Japanese had a Northeast Asia origin.

I agree with Dienekes criticism of the paper, that the Altaic shared components in Japanese may be partially a part of the Yayoi-era migrations, not only representing Jomon. So the paper may be overestimating the Jomon components.

Anyway politically and historically speaking, it is fairly obvious from this study and earlier uniparental studies that Japanese are not an ancient native homogenous population, but a population that was mixed 2kya and has homogenized since then. Thus why I have close mtDNA matches in South Korea. So much for Japanese purity.

Japanese ancestors were "gaijin"

It will all hinge on those groups being considered to have been originally Koreans or not.

At least yayois have a Chinese origin I think.

It's the lesser of two evils for them, I agree. It's hard to measure which of both groups is the more "nigger" on those islands, though.

^^ probably not all of them... there would have been Altaic proto-Koreans as well.

Jomon is the most "N"as they are mostly related to Australoids and Pacific Islanders

^^ no, you're applying western colorism to Japanese racism, but it's something different. Koreans are as much N's as anyone, straight from the mouth of my grandmother.

I was only talking on a social sense, not a physical one.
