In human genetics, Haplogroup J-M172 or J2 is a Y-chromosome haplogroup which is a subclade (branch) of haplogroup J-P209. Haplogroup J-M172 is found in Western Asia, Central Asia, South Asia, Europe and North Africa, but it is usually associated with Northwest Asia. It is thought that J-M172 might have originated between the Caucasus Mountains, Mesopotamia and the Levant.

Contents

It is further divided into two complementary clades, J-M410 and J-M12 (M12, M102, M221, M314).

Origins

The date of origin for haplogroup J-M172 was estimated by Batini et al in 2015 as between 19,000 and 24,000 Years Before Present (YBP). Samino et al in 2004 dated the origin of the parent haplogroup, J-P209, to between 18,900 and 44,500 YBP.

It is likely that J2 men had settled over most of Anatolia, the South Caucasus and Iran by the end of the Last Glaciation 12,000 years ago.

Zalloua and Wells 2004 and al-Zaheri 2003 uncovered the earliest known migration of J2, from Sumeria to Canaan. In 2001, Nebel et al. found that, "According to Underhill et al. (2000), Eu 9 (H58) evolved from Eu 10 (H71) through a T→G transversion at M172 (emphasis added)," and that in today's populations, Eu 9 (the post-mutation form of M172) is strongest in the Caucasus, Asia Minor and the Levant, whilst Eu 10 becomes stronger and replaces the frequency of Eu 9 as one moves south into the Arabian Peninsula, so that Eastern Europeans from the Caucasus met with Arabs near and between Mesopotamia (formerly Sumeria) and the Negev Desert, as "Arabisation" spread from Arabia to the Levant and Turkey, as well as many peoples (e.g. Jews, Armenians, Lebanese) having returned from diasporas.

Per research by Di Giacomo 2004, J-M172 haplogroup spread into Southern Europe" from either the Levant or Anatolia, likely parallel to the development of agriculture. As to the timing of its spread into Europe, Di Giacomo points to events which post-date the Neolithic, in particular the demographic floruit associated with the rise of the Ancient Greek world. Semino et al. derived older age estimates for overall J2 (having used the Zhivotovsky method c.f. Di Giacomo), postulating its initial spread with Neolithic farmers from the Near East. However, its subclade distribution, showing localized peaks in the Southern Balkans, southern Italy, north/central Italy and the Caucasus, does not conform to a single 'wave-of-advance' scenario, betraying a number of still poorly understood post-Neolithic processes which created its current pattern. Like Di Giacomo, the Bronze Age southern Balkans was suggested by Semino 2004 to have been an important vector of spread.

Distribution

Haplogroup J-M172 is found mainly in the Fertile Crescent, the Caucasus (Nasidze 2003), Anatolia, Italy, the Mediterranean littoral, and the Iranian plateau(Semino 2004).

The highest reported frequency of J-M172 ever was 87.4%, among Ingush in Malgobek (Balanovsky 2011).

More specifically it is found in Iraq (Al-Zahery 2003), Kuwait (Qassemi 2009), Syria (Luis 2004), Lebanon (Zalloua 2008l), Turkey (Cinnioglu 2004), Georgia (Nasidze 2003), Azerbaijan (Di Giacomo 2004), North Caucasus (Nasidze 2004), Armenia (Wells 2001), Iran (Nasidze 2004), Israel (Semino 2004), Palestine (Semino 2004), Cyprus (Capelli 2005), Greece (Martinez 2007), Albania (Semino 2000), Italy (Capelli 2007), and Spain (Di Giacomo 2003), and more frequently in Iraqis 24%Al-Zahery 2011, Chechens 51.0%-58.0% (Balanovsky 2011), Georgians 21% (Wells 2001)-72% (Wells 2001), Lebanese 30%(Semino 2004), Ossetians 24%(Nasidze 2004), Balkars 24% (Battaglia 2008), Syrians 23% (Luis 2004), Turks 13% (Cinnioglu 2004)-40% (Semino 2000), Cypriots 12.9% (El-Sibai 2009)-37%(Capelli 2005), Armenians 21% (Wells 2001)-24% (Nasidze 2004), Circassians 21.8%,(Balanovsky 2011) Iranians 10% (Nasidze 2004)-25%, (Wells 2001) Albanians 16% (Battaglia 2008)-24%, (Semino 2000) Italians 9%-36% (Capelli 2007), Sephardi Jews 15%(Nebel 2001)-29%, (Semino 2004) Maltese 21%(Capelli 2005), Palestinians 17%(Semino 2004), Saudis 14% (Abu-Amero 2009), Jordanians 14%, Omanis 10%-15% (Di Giacomo 2004) and (Luis 2004), and North Indian Shia Muslim 18% (Eaaswarkhanth 2009).

Central Asia

J-M172 is found at moderate frequencies among Central Asian people such as Uyghurs, Uzbeks, Turkmens, Tajiks, Kazakhs, and Yaghnobis. According to the genetic study in Northeast China by Shou et al. (2010), a notable high frequency of J-M172 is observed particularly in Uyghurs 34% and Uzbeks 30.4% in East Turkestan, China. J*-M304, which is the genetic marker to define Paragroup J-P209, is also found among Xibo, Kazakh, Dongxiang and Uzbek people in Northwest China. This study also displays how far lineage J2 reached eastward, and it is also noted that the estimated age of J2-M172 in this region seems more ancient than the history of Islam.(Shou 2010)

In 2015, two ancient samples of J2-M172 (J2a) were found in two different archaeological sites, Kytmanovo and Sary-bel kurgan, which are located in Altai, Russia. Both of the ancient samples are related to Iron Age cultures in Altai. Sary-bel J2a is dated to 50 BC whereas Kytmanovo sample is dated to 721-889 AD. Genetic admixture of these samples also displays that Iron Age Altaians are more West Eurasian than contemporary Altaians, and these ancient J2a samples seem to be more related to present-day Turkic people based on Gedmatch results.

Europe

In Europe, the frequency of Haplogroup J-M172 drops as one moves northward away from the Mediterranean. In Italy, J-M172 is found with regional frequencies ranging between 9% and 36% (Capelli 2007). In Greece, it is found with regional frequencies ranging between 10% and 48%. Approximately 24% of Turkish men are J-M172 according to a recent study, (Cinnioglu 2004) with regional frequencies ranging between 13% and 40% (Semino 2000). Combined with J-M267, up to half of the Turkish population belongs to Haplogroup J-P209.

It has been proposed that haplogroup subclade J-M410 was linked to populations on ancient Crete by examining the relationship between Anatolian, Cretan, and Greek populations from around early Neolithic sites in Crete. Haplogroup J-M12 was associated with Neolithic Greece (ca. 8500 - 4300 BCE) and was reported to be found in modern Crete (3.1%) and mainland Greece (Macedonia 7.0%, Thessaly 8.8%, Argolis 1.8%) (King 2008).

North Caucasus

J-M172 is found at very high frequencies in certain peoples of the Caucasus: among the Ingush 87.4% (Balanovsky 2011), Chechens 55.2% (Balanovsky 2011), Georgians 21%-72%, (Wells 2001), Azeris 24% (Di Giacomo 2004)-48%, (Wells 2001) Abkhaz 25%, (Nasidze 2004) Balkars 24% (Battaglia 2008), Ossetians 24% (Nasidze 2004), Armenians 21% (Wells 2001)-24% (Nasidze 2004), Circassians 21.8% (Balanovsky 2011), and other groups ( Nasidze 2004 and Nasidze 2003).

West Asia

Sephardi Jews have about 15% (Nebel 2001)-29% (Semino 2004), of haplogroup J-M172, and Ashkenazi Jews have 15% (Shen 2004)-23% (Semino 2004). It was reported in an early study which tested only four STR markers (Malaspina 2001) that a small sample of Italian Cohens belonged to Network 1.2, an early designation for the overall clade now known as J-L26, defined by the deletion at DYS413. However, a large number of all Jewish Cohens in the world belong to haplogroup J-M267 (see Cohen modal haplotype).

Haplogroup J-M172 has been shown to have a more northern distribution in the Middle East, although it exists in significant amounts in the southern middle-east regions, a lesser amount of it was found when compared to its brother haplogroup, J-M267, which has a high frequency southerly distribution. It was believed that the source population of J-M172 originated from the Levant/Syria (Syrid-J-M172), and that its occurrence among modern populations of Europe, Central Asia, and South Asia was a sign of the neolithic agriculturalists. However, as stated it is now more likely to have originated in regions farther to the north, with the first metallurgists of the Middle East.

South Asia

J2-M172 was found to be significantly higher among Dravidian castes at 19% than among Indo-European castes at 11%. J2-M172 and J-M410 is found 21% among Dravidian middle castes, followed by upper castes, 18.6%, and lower castes 14%. J2 is present in Indian tribals too and has a frequency of 11% in Austro-Asiatic tribals. Among the Austro-Asiatic tribals, the predominant J2 occurs in the Lodha(35%) of West Bengal. J2 is also present in the South Indian hill tribe Toda at a frequency of 38.46% and in the Kol tribe of Uttar Pradesh at a frequency of 33.34%. Haplogroup J-P209 was found to be more common in India's Shia Muslims, of which 28.7% belong to haplogroup J, with 13.7% in J-M410, 10.6% in J-M267 and 4.4% in J2b (Eaaswarkhanth 2009).

In Pakistan, the highest frequencies of J2-M172 were observed among the Parsis at 38.89%, the Dravidian speaking Brahui's at 28.18% and the Makrani Balochs at 24%. It also occurs at 18.18% in Makrani Siddis and at 3% in Karnataka Siddis.

J2-M172 is found at an overall frequency of 16.1% in the people of Sri Lanka. In Maldives, 22% of Maldivian population were found to be haplogroup J2 positive. Subclades of M172 such as M67 and M92 were not found in either Indian or Pakistani samples which also might hint at a partial common origin.

Subclade distribution

Haplogroup J-M172 is subdivided into two complementary sub-haplogroups: J-M410, defined by the M410 genetic marker, and J-M12, defined by the M12 genetic marker.

Phylogenetics

In Y-chromosome phylogenetics, subclades are the branches of haplogroups. These subclades are also defined by single nucleotide polymorphisms (SNPs) or unique event polymorphisms (UEPs).

Phylogenetic history

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, the major research groups came together and formed the Y-Chromosome Consortium (YCC). They published a joint paper that created a single new tree that all agreed to use. Later, a group of citizen scientists with an interest in population genetics and genetic genealogy formed a working group to create an amateur tree aiming at being above all timely. 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.

Research publications

The following research teams per their publications were represented in the creation of the YCC Tree.

Phylogenetic trees

There are several confirmed and proposed phylogenetic trees available for haplogroup J-M172. The scientifically accepted one is the Y-Chromosome Consortium (YCC) one published in Karafet 2008 and subsequently updated. A draft tree that shows emerging science is provided by Thomas Krahn at the Genomic Research Center in Houston, Texas. The International Society of Genetic Genealogy (ISOGG) also provides an amateur tree.
