![]() in 2015, using genome-wide SNP data comparison, found that the Hokkaido Jōmon samples, ancestral to the Ainu people, carried gene alleles associated with facial features, which are commonly found among Europeans and Middle-Easterners at a medium frequency. 2005) and resembled modern East Asian comparison samples rather than the geographical close Urawa Jomon sample." Ī study published in the scientific journal Nature by Jinam et al. This individual carried ancestry, which is widely distributed among modern East Asians (Nohira et al. (2013) described the craniometrics and aDNA sequence from a Jomon individual from Nagano (Yugora cave site) dated to the middle of the initial Jomon Period (7920–7795 cal BP). They tested for regional differences and found the Tokoku Jomon (northern Honshu) were more similar to Hokkaido Jomon than to geographically adjacent Kanto Jomon (central Honshu). (2013) analysed craniometrics and extracted aDNA from museum samples that came from the Sanganji shell mound site in Fukushima Prefecture dated to the Final Jomon Period. This observation is further substantiated by the studies of Kanzawa-Kiriyama et al. These results suggest a level of inter-regional heterogeneity not expected among Jomon groups. "In this respect, the biological identity of the Jomon is heterogeneous, and it may be indicative of diverse peoples who possibly belonged to a common culture, known as the Jomon. Īccording to the article "Jōmon culture and the peopling of the Japanese archipelago" by Schmidt and Seguchi (2014), the prehistoric Jōmon people descended from various paleolithic populations, which migrated into the Japanese archipelago, using different routes at different times. įorensic reconstruction from a Jōmon individual from Niigata prefecture.ĭental morphology suggests that the Jōmon had Sundadont dental structure which is more common among modern Southeast Asians and Indigenous Taiwanese, and is ancestral to the Sinodont dental structure commonly found among modern Northeast Asians, suggesting that the Jōmon split from the common "Ancestral East Asians" prior to the formation of modern Northeast Asians. They subsequently received some geneflow from an Upper-Paleolithic North Eurasian population ( Yana RHS), but following their migration into the Japanese archipelago, they became largely isolated from outside geneflow. Population genomic data from various Jōmon period samples show that their main ancestry component split from other East Asian people at about 15,000 BCE, after the estimated split of Ancestral Native Americans from East Asians at about 25,000 BCE. In the same study, the mean Jōmon component of the modern Japanese individual estimated using the ADMIXTURE analysis was 9.31%. The results of a study from 2021 inferred gene flow from the Jōmon period population to the modern Japanese across all migration models tested, with genetic contributions ranging from 8.9 to 11.5%. Jōmon samples represented by a specimen obtained from the Funadomari archaeological site on Rebun Island and two specimens obtained from Honshu, show that mainstream Japanese people have inherited an average of 10% Jōmon period ancestry in their genome. Multiple studies on the Jōmon population analyzed the genetic contribution towards modern Japanese. The Jōmon people may have consisted of multiple groups, which arrived and merged at different times in the Japanese archipelago, using multiple migration routes, rather than a single homogeneous people. "Jōmon people" ( 縄文 人, Jōmon jin) is the generic name of several peoples who lived in the Japanese archipelago during the Jōmon period ( c.
