Ancestry profile of Japanese genetic clusters illustrating their genetic similarities to five mainland Asian populations. [46]Gyaneshwer Chaubey and George van Driem (2020) suggest that the Jōmon people were rather heterogeneous, and that there was also a pre-Yayoi migration during the Jōmon period, which may be linked to the arrival of the Japonic languages, meaning that Japonic is one of ...
Jōmon-associated ancestry is commonly found throughout the Japanese archipelago, ranging from c. 15% among modern Japanese people, to c. 30% among Ryukyuan people, and up to c. 75% among modern Ainu people, and at lower frequency among surrounding groups, such as the Nivkhs or Ulch people, but also Koreans and other coastal groups, suggesting ...
However, recent DNA analyses revealed genetic links to both Jomon and Japanese people, as well as to the broader East Asian population cluster. The Minatogawa specimens' genetic type, based on extracted DNA alleles, was found to be common among modern Japanese peoples, Jomon and Yayoi samples, although being not their direct ancestor.
According to the recent genetic studies, the Ryukyuans share more alleles with the southern Jōmon (16,000–3,000 years ago) hunter-gatherers than the Yayoi people, who had rice farming culture, have smaller genetic contributions from Asian continental populations, which supports the dual-structure model of K. Hanihara (1991), a widely ...
Recent genetic studies on the Yayoi people suggest that they were closely related to populations from the Korean Peninsula and Northeast Asia. [22] [25] [26] [27] To what extent the Yayoi population impacted the modern Japanese gene pool is still being analyzed. For further information, see Japanese people's Dual ancestry theory.
The analysis of a Jōmon sample (Ikawazu shell-mound, Tahara, Japan) and an ancient sample from the Tibetan Plateau (Chokhopani, China) found only partially shared ancestry, pointing towards a "positive genetic bottleneck" regarding the spread of haplogroup D from ancient "East Asian Highlanders" (related to modern day Tujia people, Yao people ...
This hypothesis proposes that contemporary Japanese people are from three distinct ancestral groups: Jōmon, Yayoi and Kofun, with 13%, 16% and 71% of genetic ancestry, respectively. [3] During the Kofun period, it is said that migrant groups from China came to Japan and settled on the island, bringing with them various cultural advances and ...
The statistics also do not take into account minority groups who are Japanese citizens such as the Ainu (an aboriginal people primarily living in Hokkaido), the Ryukyuans (from the Ryukyu Islands south of mainland Japan), naturalized citizens from backgrounds including but not limited to Korean and Chinese, and citizen descendants of immigrants ...
