Where did the Japanese ancestors come from?

The Nikkei Business News and other media 20 1 2165438+1October1reported that DNA analysis confirmed that modern Japanese were handed down from the aborigines of the Japanese archipelago and the Yayoi people from the Korean peninsula.

The research team composed of the University of Tokyo and the Graduate School of a comprehensive university jointly published this research result on October 20 121October 3 1. Based on the published DNA data of about 460 Japanese indigenous scholars, Asians and westerners, the team additionally analyzed the data of 7 1 person such as dwarf slaves and Okinawa. Dwarf slaves are primitive Japanese residents who have been living in Hokkaido and other northeastern regions since the 5th century BC.

The results show that pygmy slaves are the closest to Okinawa people in genetics, followed by Japanese indigenous rope writers, Koreans and China people. At the same time, it also shows that the rope literati are genetically closer to Koreans and China than the dwarf slaves and Okinawa people.

This means that from 3000 years ago, the rope literati of the Japanese archipelago were mixed with the Yayoi people from the East Asian continent (mainly through the Korean Peninsula). On the contrary, the mixed-race between people in Hokkaido and Okinawa, which face each other from north to south, has been slow. Therefore, in these areas, the genetic characteristics of local people have been preserved relatively more.

Japan's "Economic News" commented: "Although there have been similar research results so far, this study analyzed up to 900,000 DNA mutations per person, which greatly improved the credibility." Asahi Shimbun also gave a new meaning to the research results, saying that "the research results have genetically confirmed that the mixed blood of the rope literati and the Yayoi people is the origin of the Japanese".

Extended data:

The main ethnic group in Japan is the Yamato ethnic group, also known as the Yamato ethnic group, with a population of about 65.438+0.25 billion, and its mother tongue is Japanese. The word "harmony" originated from the Yamato region where the Japanese regime was located in the 3rd century. It accounts for about 99% of Japan's total population (the rest are Ainu and Ryukyu), mainly distributed in the whole Japanese archipelago.

Sometimes it is synonymous with "Japan". For example, "Harmony" means "Japanese spirit". In the era of Japanese Empire, harmony refers to a nation different from Ainu, Ryukyu, Han and Korean, and also refers to a nation different from "Gaoshan".

Hezu is mainly composed of the residents of the Sea of Japan and the residents of East Asia who originally lived in Northeast Asia. Its ethnic group was completely formed in the ancient tomb culture, and its own culture has been influenced by the East Asian continent for a long time, but it has its own system because of its special geographical location and climate.
