Where were the Asian ancestors of South Koreans from based on DNA?
Jungeun Kim, Sungwon Jeon, Jae-Pil Choi, Asta Blazyte, Yeonsu Jeon, Jong-Il Kim, Jun Ohashi, Katsushi Tokunaga, Sumio Sugano, Suthat Fucharoen, Fahd Al-Mulla, Jong Bhak, The Origin and Composition of Korean Ethnicity Analyzed by Ancient and Present-Day Genome Sequences, Genome Biology and Evolution, Volume 12, Issue 5, May 2020, Pages 553–565, https://doi.org/10.1093/gbe/evaa062
We analyzed the haplotype distributions of 88 Koreans compared with ancient and modern whole genomes and suggested two major haplotype expansion events. A comprehensive genome comparison confirmed that Koreans possess dual ancestral genetic components originating broadly from East Siberia (E
si
) and East Asia (EA
b
). Ancient genome comparisons revealed that the genetic makeup of Koreans can be best described as an admixture of the Neolithic Devil’s Gate genome in Russia and the Iron Age Vat Komnou in Southeast Asia. Our analyses of ancient and present-day populations suggest a long and gradual admixture model of two Neolithic founders, the Devil’s Gate founder in Russia and the founder from Tianyuan Cave in China. These two major components were admixing throughout East Siberia and East Asia for an extended time up until the Neolithic period. Subpopulations of current East Asians, as well as modern Koreans, were probably established by a later regional genetic transition during the Bronze Age. The peopling of Korea is most likely a part of large population expansion and the subsequent admixture events which occurred in East Asia, rather than a unique isolated event or migration. We think that this kind of recent rapid expansion and admixture could be general models for other East Asian and Southeast Asian populations in which Bronze and Iron Age populations expanded and admixed with other peripheral region populations.
My comment :
Originally, HaploGroup O was classified as O1, O2, O3. But since 2017, it has been reclassified as O1 and O2. The paper still uses the old classification method, I still can't understand why old classification methods are used to induce confusion. And in previous studies, Haplo N and Q have been analyzed as a minority group of 1 to 2%. Suddenly, however, the interpretation of 7% and 4% as a large group raises doubts about what bias or wrong choice of the inspection group was involved in the paper.

I think this data is more accurate. It is the data surveyed on 708 samples, and there is none or little difference from previous studies.

Why is Indonesia a lot friendlier to Singapore compared to Malaysia when they have a lot more in common with the latter?
I understand that the Malay have already been ethnically displaced by the Chinese. Is that not the reason?

Why do many Koreans think Kong is from Korea?
Soybean cultivation began about 5,000 years ago, and relics and relics of carbonized soybeans have been found all over the Korean Peninsula.
Beans from the Korean Peninsula and Manchuria were brought to China through Qi during the Gojoseon Dynasty.

Philippine History Professor, Dayang Marikit thinks that the Malay language is not from Indonesia, not even a specific island and a specific part of Indonesia, and is actually foreign to Indonesia. What is the truth?

Who could be considered the most powerful woman character in Chinese mythology?
Well, the modern Chinese are descendants of the Dongyi ethnic,
who kill the children of the Nu-Wa tribe,
who kill the ethnic of the sun symbol,
who are descendants of cannibals.
The Chinese kill the original Nu-Wa people and they worship Nu-Wa.

Having worked at the Embassy of Japan to the USA, I have asked many Japanese this question. What is the name of the white triangle on the forehead of actors portraying ghosts on stage and screen?
Yeah Yeah, again, It’s returned to China's distortion play time.
Chinese argue that Dong-yi are Mainland Chinese, Qin Dynasty, South Asian, Manchurian, Korean, Japanese.
And the Qin Dynasty is ruined by Chinese immigration, South Asia is experiencing Chinese immigration, Korea is also ruined by Chinese immigration, and Japan is experiencing Chinese immigration.
I'm amazed at the history distortion techniques for Chinese immigration and reproduction.
