In other studies, haplogroup D-M174 has been observed in 6.7% (3/45) and 4.0% (3/75) of samples from Korea without any further specification of the area of sampling. In Korea, Haplogroup D-M174 has been observed in 3.8% (5/133) of a sample from Daejeon, 3/85 = 3.5% of a sample from Seoul, 3.3% (3/90) of a sample from Jeolla, 2.4% (2/84) of a sample from Gyeongsang, 2.3% (13/573) of another sample from Seoul, 1.4% (1/72) of a sample from Chungcheong, 1.1% (1/87) of a sample from Jeju, and 0.9% (1/110) of a third sample from Seoul-Gyeonggi. In another study of Han Chinese Y-DNA published in 2011, Haplogroup D-M174 was observed in 1.94% (7/361) of a sample of unrelated Han Chinese male volunteers at Fudan University in Shanghai, with the origins of most of the volunteers being traced back to East China (Jiangsu, Zhejiang, Shanghai, and Anhui). A study published in 2011 found D-M174 in 2.49% (43/1729) of Han Chinese males, with frequencies of this haplogroup tending to be higher than average toward the north and toward the west of the country (5/56 = 8.9% D-M174 Shaanxi Han, 13/221 = 5.9% D-M174 Gansu Han, 6/136 = 4.4% D-M174 Yunnan Han, 1/27 = 3.7% D-M174 Guangxi Han, 2/61 = 3.3% D-M174 Hunan Han, 2/62 = 3.2% D-M174 Sichuan Han). Haplogroup D is also found in populations of China proper and Korea, but with much lower frequency than in populations of Tibet and Japan. Haplogroup D-M174 chromosomes are also found at low to moderate frequencies among the Bai, Dai, Han, Hui, Manchu, Miao, Tujia, Xibe, Yao, and Zhuang of China and among several minority populations of Sichuan and Yunnan that speak Tibeto-Burman languages and reside in close proximity to the Tibetans, such as the Jingpo, Jino, Mosuo, Naxi, Pumi, Qiang, and Yi. The Ainu of Japan and various Tibeto-Burmese people (such as the Tripuri people) are notable for possessing almost exclusively Haplogroup D-M174 chromosomes. It is found today at high frequency among populations in Tibet, northern Myanmar, Qinghai, the Japanese archipelago, and the Andaman Islands, though curiously not as much in the rest of India. One group of population migrated to Siberia, others to Japan and Tibet, and another group migrated to the Andaman islands. Ī 2019 study by Haber et al showed that Haplogroup D-M174 originated in Central Asia and evolved as it migrated to different directions of the continent. Rather, haplogroup D was part of the standing variation carried by the Eastern OOA expansion, and later lost from most of the populations except in Andaman and partially in Japan and Tibet”. The authors concluded that: ”This strongly suggests that haplogroup D does not indicate a separate ancestry for Andamanese populations. The East Asian D1a2b had diverged from the Japanese D1a2a lineage ~53,000 years ago. The Jarawa and Onge shared this D1a2b with each other within the last ~7000 years. finds that the Riang people (a Tibeto-Burmese population) and the Andamanese share the same D clade (D1a3 also known as D2a2b), and have their closest lineages with other clades in East Asia. He suggests that there were multiple waves into Eastern Eurasia. According to Hammer et al., haplogroup D-M174 originated between Tibet and the Altai mountains. 2018) suggest that the paternal haplogroup D-M174 originated somewhere in Central Asia. 2006, Shinoda 2008, Matsumoto 2009, Cabrera et al. Haplogroup D1 is often associated with "Northern Asian" populations. While haplogroup D-M174 along with haplogroup E contains the distinctive YAP polymorphism (which indicates their closer ancestry than C), no haplogroup D-M174 chromosomes have been found anywhere outside of Asia. Haplogroup D-M174 is believed to have originated in Asia some 60,000 years before present. Haplogroup D and its subclades shown in turquoise. Haplogroup migration map within Eastern Eurasia.
