Ancient distribution

H-L901/M2939 is believed to have split from HIJK 48,500 years before present. Ancient samples of H1a have been found in Iran, Turkmenistan, Afghanistan etc., and ancient H2 samples have been found in Levant, Anatolia and Europe. It may have been present in pre-Neolithic inhabitants of South Asia. Possible site of introduction may be West Asia or (for H1) northwest part of South Asia, since it is highly concentrated there.

H1a

Shahr-i Sokhta and Gonur sites

Shahr-e Sukhteh, Iran and Gonur, Turkmenistan. H1a1d2 - Bronze Age, 3200-1900 BCE.

Gogdara and Barikot sites

With limited ancient DNA testing in South Asia, accordingly there is a limited amount of ancient samples for H1a, despite it being a populous and well distributed haplogroup today. The first set of ancient DNA from South Asia was published in 2019. 65 samples were collected from the Swat Valley of northern Pakistan, 2 of which belonged to H1a.

H2

The earliest sample of H2 is found in the Pre-Pottery Neolithic B culture of the Levant 10,300 years ago. From ancient samples, it is clear that H2 also has a strong association with the spread of agriculture from Anatolia into Europe, and is commonly found with haplogroup G2a. H2 was found in Neolithic Anatolia, as well as in multiple later Neolithic cultures of Europe, such as the Vinča culture in Serbia, and the Megalith culture of Western Europe.

The 2021 study "Using Y-chromosome capture enrichment to resolve haplogroup H2 shows new evidence for a two-path Neolithic expansion to Western Europe" found that while H2 is less than 0.2% in modern-day western European populations it was more common during the Neolithic, between 1.5 and 9%. They identified two major clades H2m and H2d. With respect to the current ISOGG nomenclature, H2m appears to be defined by a mix of H2, H2a, H2a1 and H2c1a SNPs while H2d appears to be defined by two H2b1 SNPs, and four additional SNPs which were previously undetected. They estimated TMRCA for H2d and H2m was  ~15.4 kya with H2m and H2d estimated TMRCAs of  ~11.8 and  ~11.9 kya respectively. H2 diversity probably existed in Near-Eastern hunter-gatherers and early farmers, and subsequently spread via the Neolithic expansion into Central and Western Europe. H2d was found along the inland/Danubian route into central Europe, but most H2m individuals are found along the Mediterranean route into Western Europe, the Iberian Peninsula and ultimately, Ireland.

There were also two occurrences of H2a found in the Neolithic Linkardstown burials in the southeast Ireland. More Neolithic H2 samples have been found in Germany and France.

Roma people

Haplogroup H-M82 is a major lineage cluster in the Roma, especially Balkan Roma, among whom it accounts for approximately as high as 60% of males. A 2-bp deletion at M82 locus defining this haplogroup was also reported in one-third of males from traditional Roma populations living in Bulgaria, Spain, and Lithuania. High prevalence of Asian-specific Y chromosome haplogroup H-M82 supports their Indian origin and a hypothesis of a small number of founders diverging from a single ethnic group in India (Gresham et al. 2001).

Within the H-M82 haplogroup, an identical 8-microsatellite Y-chromosome haplotype is shared by nearly 30% of Gypsy men, an astonishing degree of preservation of a highly differentiated lineage, previously described only in Jewish priests. (A newly discovered founder population: the Roma/Gypsies - Stanford Medicine 2005)Within the H-M82 haplogroup, an identical 8-microsatellite Y chromo-some haplotype is shared by nearly 30% of Gypsy men, an astonishing degree of preservation of a highly differentiated lineage, previously described only in Jewish priests.

Important studies show a limited introgression of the typical Roma Y-chromosome haplogroup H1 in several European groups, including approximately 0.61% in Gheg Albanians and 2.48% in Tosk Albanians.

Europe, Caucasus, Central Asia & Middle East

Haplogroup H1a is found at much lower levels outside of the Indian subcontinent and the Roma populations but is still present in other populations:

• Europe - 0.9% (1/113) H-M82 in a sample of Serbians, 2% (1/57) H-M82 in a sample of Macedonian Greeks, 1% (1/92 H-M82) to 2% (1/50 H-M69) of Ukrainians, H1a2a in 1.3% (1/77) of a sample of Greeks. to 7.5% (3/40 H-M82) of Romanians
• Caucasus- 2.6% (1/38) H-M82 in a sample of Balkarians,
• Central Asia - 12.5% (2/16) H-M52 in a sample of Tajiks from Dushanbe, 5.19% (7/135) H-M69 in a sample of Salar from Qinghai, 5.13% (2/39) H (including 1/39 H(xH1,H2) and 1/39 H1) in a sample of Uyghurs from Darya Boyi Village, Yutian (Keriya) County, Xinjiang, 4.65% (6/129) H-M69 in a sample of Mongols from Qinghai, 4.44% (2/45) H-M52 in a sample of Uzbeks from Samarkand, 3.56% (17/478) H-M69 and 0.84% (4/478) F-M89(xG-M201, H-M69, I-M258, J-M304, L-M20, N-M231, O-M175, P-M45, T-M272) in a sample of Uyghurs from the Hotan area, Xinjiang, 2.86% (2/70) H-M52 in a sample of Uzbeks from Xorazm, 2.44% (1/41) H-M52 in a sample of Uyghurs from Kazakhstan, 1.79% (1/56) H-M52 in a sample of Uzbeks from Bukhara, 1.71% (3/175) H-M69 in a sample of Hui from the Changji area, Xinjiang, 1.59% (1/63) H-M52 in a sample of Uzbeks from the Fergana Valley, 1.56% (1/64) H1 in a sample of Uyghurs from Qarchugha Village, Yuli (Lopnur) County, Xinjiang, 1.32% (1/76) H2 in a sample of Uyghurs from Horiqol Township, Awat County, Xinjiang, 0.99% (1/101) H-M69 in a sample of Kazakhs from the Hami area, Xinjiang.

East & South-East Asia

At the easternmost extent of its distribution, Haplogroup H-M69 has been found in Thais from Thailand (1/17 = 5.9% H-M69 Northern Thailand; 2/290 = 0.7% H-M52 Northern Thai; 2/75 = 2.7% H-M69(xM52) and 1/75 = 1.3% H-M52(xM82) general population of Thailand), Balinese (19/551 = 3.45% H-M69), Tibetans (3/156 = 1.9% H-M69(xM52, APT)), Filipinos from southern Luzon (1/55 = 1.8% H-M69(xM52)), Bamars from Myanmar (1/59 = 1.7% H-M82, with the relevant individual having been sampled in Bago Region), Chams from Binh Thuan, Vietnam (1/59 = 1.7% H-M69), and Mongolians (1/149 = 0.7% H-M69). The subclade H-M39/M138 has been observed in the vicinity of Cambodia, including one instance in a sample of six Cambodians and one instance in a sample of 18 individuals from Cambodia and Laos. A genome study about Khmer people resulted in an average amount of 16,5% of Khmer belonging to y-DNA H.

H1b

H1b is defined by the SNPs - B108, Z34961, Z34962, Z34963, and Z34964. Only discovered in 2015, H1b was detected in a single sample from an individual in Myanmar. Due to only being classified recently, there are currently no studies recording H1b in modern populations.

H2

H2 (H-P96), which is defined by seven SNPs – P96, M282, L279, L281, L284, L285, and L286 – is the only primary branch found mainly outside South Asia. Formerly named F3, H2 was reclassified as belonging to haplogroup H due to sharing the marker M3035 with H1. While being found in numerous ancient samples, H2 has only been found scarcely in modern populations across West Eurasia.

H3

H3 (Z5857) like H1, is also mostly centered in South Asia, albeit at much lower frequencies.

Like other branches of H, due to it being newly classified it is not explicitly found in modern population studies. Samples belonging to H3 were likely labeled under F*. In consumer testing, it has been found principally among South Indians and Sri Lankans, and other areas of Asia such as Arabia as well. ----The following gives a summary of most of the studies which specifically tested for the subclades H1a1a (H-M82) and H2 (H-P96), formerly F3, showing its distribution in different part of the world.
