Гаплогруппа D1: Происхождение и распространение в Азии

Haplogroup D1 or D M174 is a subclade of haplogroup D CTS3946. This male haplogroup is found primarily in East Asia, Magar ethnic Nepal and the Andaman Islands. It is also found regularly with lower frequency in Central Asia and Mainland Southeast Asia, and, more rarely, in Europe and the Middle East.

Haplogroup D M174 is believed to have originated in Asia some 60,000 years ago. 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 outside of Asia. A 2017 study by Mondal et al. finds that the Riang people (a Tibeto Burmese population) and the Andamanese share the same D clade (D1a3, also known as D1a2b) and have their closest lineages with other clades in East Asia. The Jarawa and Onge shared D1a2b with each other within the last ~7,000 years. The East Asian D1a2b diverged from the Japanese D1a2a lineage ~53,000 years ago. The authors conclude: "This strongly suggests that haplogroup D does not indicate a separate ancestry for Andamanese populations. 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". A 2020 genetic study by Hallast et al. on ancient and modern haplogroups using a phylogenetic analysis of haplogroup C, D, and FT sequences—including very rare deep rooting lineages such as D0/D2, a divergent D lineage not belonging to D M174—argues that the initial splits within haplogroup CT (an ancestor of DE) occurred in Africa. It also argues that phylogeographic analyses of ancient and present day non African Y chromosomes all point to East/Southeast Asia as the origin of all known surviving non African male lineages (apart from recent migrants) soon after an initial 70,000–55,000 year ago migration from Africa of basal haplogroup D and other basal Y lineages. It argues that these lineages then rapidly expanded across Eurasia, diversified in Southeast Asia, and expanded westward around 55,000–50,000 years ago, replacing other local lineages within Eurasia; haplogroup D (as D M174) then underwent rapid expansions within Eastern Eurasian populations and consists of five branches that formed about 45,000 years ago. The study finds that these haplogroups currently have their greatest diversity in Eastern Eurasia (East/Southeast Asia). Tibeto Burmese populations of East and Southeast Asia were found to have the highest amount of diversity.

Haplogroup D M174 is found today with high frequency among populations in Tibet, Magar ethnic Nepal, northern Myanmar, Qinghai, the Japanese archipelago, and the Andaman Islands, though curiously not as much in the rest of India. The Ainu people of Japan and various Tibeto Burmese people (such as the Tripuri people) are notable for possessing almost exclusively haplogroup D M174 chromosomes. 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 peoples 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. Haplogroup D is also found in populations in China proper and in Korea, but with much lower frequency than in Tibet and Japan. A study published in 2011 found D M174 in 2.49% (43/1729) of Han Chinese males, with frequencies tending to be higher than average toward the north and west of the country (8.9% of Shaanxi Han, 5.9% of Gansu Han, 4.4% of Yunnan Han, 3.7% of Guangxi Han, 3.3% of Hunan Han, and 3.2% of Sichuan Han). 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). In Korea, haplogroup D M174 was observed in 3.8% (5/133) of a sample from Daejeon, 3.5% (3/85) of a sample from Seoul,)

It has also been found among linguistically similar (Turkic or Mongolic speaking) modern populations of the desert and oasis belt south of the steppe, such as Yugurs, Bao’an, Monguors, Uyghurs, and Uzbeks. In commercial testing, members have been found as far west as Romania in Europe and Iraq in Western Asia. Unlike haplogroup C M217, haplogroup D M174 is not found in the New World; it is not present in any modern Native American (North, Central, or South) populations. While it is possible that it traveled to the New World like haplogroup C M217, those lineages apparently became extinct. Haplogroup D M174 is remarkable for its rather extreme geographic differentiation, with a distinct subset of chromosomes being found exclusively in each of the populations that contains a large percentage of individuals whose Y chromosomes belong to haplogroup D M174: haplogroup D M15 among Tibetans, as well as other East/Southeast Asian populations that display low frequencies of haplogroup D M174 Y chromosomes; haplogroup D M55 among the various populations of the Japanese archipelago and with low frequency among Koreans; and haplogroup D P99 among the inhabitants of Tibet and some other parts of central Eurasia (e. g. Mongolia and the Altai Another type (or types) of paragroup D M174* without positive tested subclades of D M15, D P47, or D M55 is found at a very low frequency among the Turkic and Mongolic populations of Central Asia, amounting to no more than 1% in total. This apparently ancient diversification of haplogroup D M174 suggests that it may perhaps be better characterized as a "super haplogroup" or "macro haplogroup". In one study, the frequency of haplogroup D M174 without positive tested subclades found among Thais was 10%. Meanwhile, the authors found D M15 in 15% of a pair of samples of Yao, including 30% (3/10) Yao Jinxiu and 0% (0/10) Yao Nandan; 14.3% (2/14) of a sample of Yi; 3.8% (1/26) of a sample of Cambodians; and 3.6% (1/28) of a sample of Zhuang.

The haplogroup D M174 Y chromosomes that are found among Tibeto Burman populations as well as people of the Japanese archipelago belong to haplogroup D1a2b, D1a2a, and D1a1. D M55 (D1a2a) is particularly distinctive, bearing a complex of at least five individual mutations along an internal branch of the haplogroup D M174 phylogeny, thus distinguishing it clearly from the other haplogroup D M174 chromosomes that are found among Tibetans and Andaman Islanders and providing evidence that Y chromosome haplogroup D M55 was the modal haplogroup in the ancestral population that developed the prehistoric Jōmon culture in the Japanese islands. It is suggested that the majority of D M174 Y chromosome carriers migrated from Central Asia to East Asia. One group migrated to the Andaman Islands, thus forming or helping to form the Andamanese people. Another group stayed in modern Tibet and southern China (today Tibeto Burman peoples), and a third group migrated to Japan, possibly via the Korean Peninsula (pre Jōmon people). Subsequently, Y DNA belonging to haplogroup D M15 has been found frequently among Tibeto Burman speaking populations of Southwestern China (including approximately 23% of Qiang, approximately 12.5% of Tibetans,), and among Yao people inhabiting northeastern Guangxi (6/31 = 19.4% Lowland Yao, 5/41 = 12.2% Native Mien, 3/41 = 7.3% Lowland Kimmun),

This subclade is found with high frequency among Pumi, and with medium frequency among Japanese and Ryukyuans. Hammer et al. (2006) found haplogroup D P37.1 in 4.0% (3/75) of a sample from South Korea. According to Mitsuru Sakitani, haplogroup D1 arrived from Central Asia to northern Kyushu via the Altai Mountains and the Korean Peninsula more than 40,000 years ago, and haplogroup D M55 (D1a2a) was born in the Japanese archipelago.

D M174 (xM15,P99,M55) is found in some Tibetan minority tribes in Northeast India (among whom rates vary from 0% to 65%). The basal D M174 (xM15, P47, M55) has been found in approximately 5% of Altaians. Kharkov et al. found haplogroup D*(xD M15) in 6.3% (6/96) of a pool of samples of Southern Altaians from three different localities, particularly in Kulada (5/46 = 10.9%) and Kosh Agach (1/7 = 14%), though they did not test for any marker of the subclade D M55 or D P99. Kharkov et al. also reported finding haplogroup DE M1(xD M174) Y DNA in one Southern Altaian individual from Beshpeltir (1/43 = 2.3%). In 2023 found in one Individual in North America, Ramon Moses, Lacrosse, Wi, USA. D M174.

Prior to 2002, there were in academic literature at least seven naming systems for the Y chromosome phylogenetic tree. This led to considerable confusion. In 2002, major research groups came together and formed the Y Chromosome Consortium (YCC). They published a joint paper that created a single new tree. Later, a group of citizen scientists with an interest in population genetics and genealogy formed a working group to create an amateur tree. The table below brings together all of these works at the point of the landmark 2002 YCC tree. This allows a researcher reviewing older published literature to quickly move between nomenclatures.
