Haplogroup R1a, or haplogroup R-M420, is a human Y-chromosome DNA haplogroup which is distributed in a large region in Eurasia, extending from Scandinavia, Central Europe and southern Siberia to South Asia.[1][2]

While R1a originated ca. 22,000[3] to 25,000[2] years ago, its subclade M417 (R1a1a1) diversified ca. 5,800 years ago.[4] The distribution of M417-subclades R1-Z282 (including R1-Z280)[5] in Central- and Eastern Europe and R1-Z93 in Asia[5][2] suggests that R1a1a diversified within the Eurasian Steppes or the Middle East and Caucasus region.[5] The place of origin of these subclades plays a role in the debate about the origins of Indo-Europeans.

The SNP mutation R-M420 was discovered after R-M17 (R1a1a), which resulted in a reorganization of the lineage in particular establishing a new paragroup (designated R-M420*) for the relatively rare lineages which are not in the R-SRY10831.2 (R1a1) branch leading to R-M17.


R1a origins[edit]

Tatiana et al. (2014) "rapid diversification process of K-M526 likely occurred in Southeast Asia, with subsequent westward expansions of the ancestors of haplogroups R and Q." [6]

The split of R1a (M420) is computed to ca. 22,000,[3] or 25,000[2] years ago, which is the time of the last glacial maximum. A large, 2014 study by Peter A Underhill et al., using 16,244 individuals from over 126 populations from across Eurasia, concluded that there was compelling evidence that "the initial episodes of haplogroup R1a diversification likely occurred in the vicinity of present-day Iran."[2]

Diversification of R1a1a1 (M417) and ancient migrations[edit]

R1a1a1 proposed steppe origins and migrations

According to Underhill (2014), the downstream R1a-M417 subclade diversified into Z282 and Z93 circa 5,800 years ago.[4][note 1] The question of the origins of R1a1a is relevant to the ongoing debate concerning the urheimat of the proto-Indo-European people, and may also be relevant to the origins of the Indus Valley Civilisation. R1a shows a strong correlation with Indo-European languages of western/southern Asia and eastern Europe,[9][1] being most prevalent in Poland, Russia and Ukraine in Europe and in central Asia, Afghanistan, Pakistan and India in Asia. In Eastern Europe Z282 is prevalent, while in South Asia Z93 dominates. The connection between Y-DNA R-M17 and the spread of Indo-European languages was first noted by T. Zerjal and colleagues in 1999.[10]

Steppe origins[edit]

Proposed steppe dispersal of R1a1a[edit]

Kivisild et al. (2003) have proposed either south or west Asia,[11][note 2] while Mirabal et al. (2009) see support for both south and central Asia.[9] Other studies suggest Ukrainian,[12] Central Asian[13] and West Asian origins for R1a1a.[14][1][15][5][2]

Ornella Semino et al. (2000) proposed Ukrainian origins, and a postglacial spread of the R1a1 gene during the Late Glacial Maximum, subsequently magnified by the expansion of the Kurgan culture into Europe and eastward.[16] Spencer Wells proposes central Asian origins, suggesting that the distribution and age of R1a1 points to an ancient migration corresponding to the spread by the Kurgan people in their expansion from the Eurasian steppe.[13] According to Pamjav et al. (2012), R1a1a diversified in the Eurasian Steppes or the Middle East and Caucasus region:

Inner and Central Asia is an overlap zone for the R1a1-Z280 and R1a1-Z93 lineages [which] implies that an early differentiation zone of R1a1-M198 conceivably occurred somewhere within the Eurasian Steppes or the Middle East and Caucasus region as they lie between South Asia and Central- and Eastern Europe."[5]

Three genetic studies in 2015 gave support to the Kurgan theory of Gimbutas regarding the Indo-European Urheimat. According to those studies, haplogroups R1b and R1a, now the most common in Europe (R1a is also common in South Asia) would have expanded from the Russian steppes, along with the Indo European languages; they also detected an autosomal component present in modern Europeans which was not present in Neolithic Europeans, which would have been introduced with paternal lineages R1b and R1a, as well as Indo European Languages.[17][18][19]

David Anthony considers the Yamna culture to be the Indo-European Urheimat.[20][21] According to Haak et al. (2015), a massive migration from the Yamna culture northwards took place ca. 2,500 BCE, accounting for 75% of the genetic ancestry of the Corded Ware culture, noting that R1a and R1b may have "spread into Europe from the East after 3,000 BCE".[22] Yet, all their seven Yamna samples belonged to the R1b-M269 subclade,[22] but no R1a1a has been found in their Yamna samples.[23] This raises the question where the R1a1a in the Corded Ware culture came from, if it was not from the Yamna culture.[24][25]

R1a may have migrated from the Anatolian-Iranian area via Central Asia to Eastern Europe, in concreto the Comb Ware culture (4,200 BCE – 2,000 BCE),[26] which was partly absorbed by the Corded Ware culture. R1a1 has been found in samples from the Narva culture,[26] which was part of the Comb Ware culture. Horvath rejects this possible migration route, given the dominance of haplogroup N1c in the Comb Ware culture, and that the Corded ware autosomal DNA is derived from the Yamna culture, and not from the Comb Ware culture.[26] In contrast, Semenov and Bulat do argue for such an origin of R1a1a in the Corded ware culture, noting that several publications point to the presence of R1a1 in the Comb Ware culture.[27][note 3]

Horvath proposes a migration of R1a from the Anatolian-Iranian area to the Pontic steppe via the Balkan.[24] Horvath notes that Haak et al. (2015) found that part of the Yamna ancestry derived from the Middle East, and that neolithic techniques probably arrived at the Yamna culture from the Balkans.[28][note 4] Horvath further notes that in the area of the Rossen culture (4,600–4,300 BC), which was situated on Germany and predates the Corded Ware culture, an old subclade of R1a, namely L664, can still be found.[30][note 5] From these facts Horvath speculates that R1a arrived in the Balkans via Anatolia, and from there spread first north-west to the Rossen culture, and then east from the Cucuteni culture to the Yamna and Afanasevo cultures, despite the absence of R1a from intermediate cultures between the Near East, Anatolia and the Balkans.[31][note 6][note 7]

Transcaucasia & West Asian origins and possible influence on Indus Valley Civilisation[edit]

Part of the South Asian genetic ancestry derives from west Eurasian populations, and some researchers have implied that Z93 may have come to India via Iran[33] and expanded there during the Indus Valley Civilisation.[2][34]

Mascarenhas et al. (2015) note that the roots of Z93 lie in West Asia, and propose that "Z93 and L342.2 expanded in a southeasterly direction from Transcaucasia into South Asia,"[33] noting that such an expansion is compatible with "the archeological records of eastward expansion of West Asian populations in the 4th millennium BCE culminating in the so-called Kura-Araxes migrations in the post-Uruk IV period."[33] Yet, Lazaridis noted that sample I1635 of Lazaridis et al. (2016), their Armenian Kura-Araxes sample, carried Y-haplogroup R1b1-M415(xM269)[note 8] (also called R1b1a1b-CTS3187).[35]

According to Underhill et al. (2014/2015) the diversification of Z93 and the "early urbanization within the Indus Valley [...] occurred at [5,600 years ago] and the geographic distribution of R1a-M780 (Figure 3d[note 9]) may reflect this."[2][note 10] Poznik et al. (2016) note that 'striking expansions' occurred within R1a-Z93 at ~4,500–4,000 years ago, which "predates by a few centuries the collapse of the Indus Valley Civilisation."[34]

Proposed South Asian origins[edit]

Kivisild et al. (2003) have proposed either South or West Asia,[11][note 2] while Mirabal et al. (2009) see support for both South and Central Asia.[9]

South Asian populations have the highest STR diversity within R1a1a,[37][38][9][1][3][39] and subsequent older TMRCA datings, and R1a1a is present among both higher (Brahmin) castes and lower castes, although the presence is substantially higher among Brahmin castes.[3][39] From these findings some researchers have concluded that R1a1a originated in South Asia,[38][3][note 11] excluding a substantial genetic influx from Indo-European migrants.[38][37][1]

However, this diversity (but not the TMRCA dating) could be partially explained by historically high population numbers[citation needed], which increases the likelihood of diversification and microsatellite variation. According to Sengupta et al. (2006), "[R1a1 and R2] could have actually arrived in southern India from a southwestern Asian source region multiple times."[37][note 12] Silva et al. (2017) notes R1a in South Asia most "likely spread from a single Central Asian source pool, there do seem to be at least three and probably more R1a founder clades within the Subcontinent, consistent with multiple waves of arrival."[41]


The R1a family tree now has three major levels of branching, with the largest number of defined subclades within the dominant and best known branch, R1a1a (which will be found with various names; in particular, as "R1a1" in relatively recent but not the latest literature.)


The topology of R1a is as follows (codes [in brackets] non-isogg codes):[42][8][43][44][45] Tatiana et al. (2014) "rapid diversification process of K-M526 likely occurred in Southeast Asia, with subsequent westward expansions of the ancestors of haplogroups R and Q." [46]

Haplogroup R[edit]


R-M173 (R1)[edit]

R1a is distinguished by several unique markers, including the M420 mutation. It is a subclade of Haplogroup R-M173 (previously called R1). R1a has the sister-subclades Haplogroup R1b-M343, and the paragroup R-M173*.

R-M420 (R1a)[edit]

R-M420, defined by the mutation M420, has two branches: R-SRY1532.2, defined by the mutation SRY1532.2, which makes up the vast majority; and R-M420*, the paragroup, defined as M420 positive but SRY1532.2 negative. (In the 2002 scheme, this SRY1532.2 negative minority was one part of the relatively rare group classified as the paragroup R1*.) Mutations understood to be equivalent to M420 include M449, M511, M513, L62, and L63.[1][49]

Only isolated samples of the new paragroup R-M420* were found by Underhill 2009, mostly in the Middle East and Caucasus: 1/121 Omanis, 2/150 Iranians, 1/164 in the United Arab Emirates, and 3/612 in Turkey. Testing of 7224 more males in 73 other Eurasian populations showed no sign of this category.[1]

R-SRY1532.2 (R1a1)[edit]

R1a1 is defined by SRY1532.2 or SRY10831.2), understood to always include SRY10831.2, M448, L122, M459, and M516.[1][50]) This family of lineages is dominated by M17 and M198. In contrast, paragroup R-SRY1532.2* lacks either the M17 or M198 markers.

The R-SRY1532.2* paragroup is apparently less rare than R1*, but still relatively unusual, though it has been tested in more than one survey. Underhill et all. (2009) reported 1/51 in Norway, 3/305 in Sweden, 1/57 Greek Macedonians, 1/150 Iranians, 2/734 ethnic Armenians, and 1/141 Kabardians.[1] Sahoo et al. (2006) reported R-SRY1532.2* for 1/15 Himachal Pradesh Rajput samples.[38]

R-M17/M198 (R1a1a)[edit]

The following SNPs are associated with R1a1a:

R-M17 (R1a1a1)[edit]

R1a1a1 (RM-417) is the most widely found subclade, in two variations which are found respectively in Europe (R1a1a1b1 (R-Z282) ([R1a1a1a*] (R-Z282) (Underhill 2014/2015)[44]) and Central and South Asia (R1a1a1b2 (R-Z93) ([R1a1a2*] (R-Z93) Underhill 2014/2015)[44]).

R-Z282 (R1a1a1b1a) (Eastern Europe)[edit]

This large subclade appears to encompass most of the R1a1a found in Europe.[51]

  • R1a1a1b1a [R1a1a1a* (Underhill (2014))] (R-Z282*) occurs in northern Ukraine, Belarus, and Russia at a frequency of ~20%. (Underhill et al. 2014)
  • R1a1a1b1a3 [R1a1a1a1 (Underhill (2014))] (R-Z284) occurs in Northwest Europe and peaks at ~20% in Norway. (Underhill et al. 2014)
  • R1a1a1c (M64.2, M87, M204) is apparently rare: it was found in 1 of 117 males typed in southern Iran.[14]
R-M458 (R1a1a1b1a1)[edit]
File:R-M458 frequency distribution.PNG
Frequency distribution of R-M458

R-M458 is a mainly Slavic SNP, characterized by its own mutation, and was first called cluster N. Underhill et al. (2009) found it to be present in modern European populations roughly between the Rhine catchment and the Ural Mountains and traced it to "a founder effect that [...] falls into the early Holocene period, 7.9±2.6 KYA."[52] M458 was found in one skeleton from a 14th-century grave field in Usedom, Mecklenburg-Vorpommern, Germany.[53] The paper by Underhill et al. (2009) also reports a surprisingly high frequency of M458 in some Northern Caucasian populations (for example 27.5% among Karachays and 23.5% among Balkars, 7.8% among Karanogays and 3.4% among Abazas).

R-L260 (R1a1a1b1a1a) (Gwozdz's cluster P)[edit]

R1a1a1b1a1a (R-L260), commonly referred to as West Slavic or Polish, is a subclade of the larger parent group R-M458, and was first identified as an STR cluster by Pawlowski 2002 and then by Gwozdz 2009. Thus, R-L260 was what Gwozdz 2009 called cluster "P." In 2010 it was verified to be a haplogroup identified by its own mutation (SNP).[54] It apparently accounts for about 8% of Polish men, making it the most common subclade in Poland. Outside of Poland it is less common (Pawlowski 2002). In addition to Poland, it is mainly found in the Czech Republic and Slovakia, and is considered "clearly West Slavic."[55] The founding ancestor of R-L260 is estimated to have lived between 2000 and 3000 years ago, i.e. during the Iron Age, with significant population expansion less than 1,500 years ago.[56]


R-M334 ([R1a1a1g1],[45] a subclade of [R1a1a1g] (M458)[45] c.q. R1a1a1b1a1 (M458)[42]) was found by Underhill et al. (2009) only in one Estonian man and may define a very recently founded and small clade.[1]

R1a1a1b1a2 (S466/Z280, S204/Z91)[edit]
R1a1a1b1a2b3* (Gwozdz's Cluster K)[edit]

R1a1a1b1a2b3* (M417+, Z645+, Z283+, Z282+, Z280+, CTS1211+, CTS3402, Y33+, CTS3318+, Y2613+) (Gwozdz's Cluster K)[43] is a STR based group that is R-M17(xM458). This cluster is common in Poland but not exclusive to Poland.[56]

R1a1a1b1a2b3a (R-L365)[edit]

R1a1a1b1a2b3a (R-L365)[42] was early called Cluster G.[citation needed]

R1a1a1b2 (R-Z93) (Asia)[edit]

This large subclade appears to encompass most of the R1a1a found in Asia.[51]

  • R1a1a1b2 [R1a1a2* (Underhill (2014))] (R-Z93) is most common (>30%) in the South Siberian Altai region of Russia, cropping up in Kyrgyzstan (6%) and in all Iranian populations (1–8%).[57]
  • R1a1a1b2a* (R-Z2125): This subgroup occurs at highest frequencies in Kyrgyzstan and in Afghan Pashtuns (>40%). At a frequency of >10% it is also observed in other Afghan ethnic groups and in some populations in the Caucasus and Iran.[57]

  • R-M434 is a subclade of Z2125. It was detected in 14 people (out of 3667 people tested) all in a restricted geographical range from Pakistan to Oman. This likely reflects a recent mutation event in Pakistan (Underhill 2009).
  • R1a1b2a1* (R-M560 is very rare and was only observed in four samples: two Burushaski speakers (north Pakistan), one Hazara (Afghanistan), and one Iranian Azerbaijani.[57]
  • R1a1b2a2* (R-M780) occurs at high frequency in South Asia: India, Pakistan, Afghanistan, and the Himalayas. The group also occurs at >3% in some Iranian populations and is present at >30% in Roma from Croatia and Hungary.[57]

Haplogroup R1a has been found in ancient fossils associated with the Corded Ware culture[58][59] and Urnfield culture;[60][unreliable source?] as well as the burial of the remains of the Sintashta culture,[61] Andronovo culture,[62] the Pazyryk culture,[63] Tagar culture[62] and Tashtyk culture,[62] the inhabitants of ancient Tanais,[64] in the Tarim mummies,[65] the aristocracy Xiongnu.[66] in two ancient Khazar fossils. The skeletal remains of a father and his two sons, from an archaeological site discovered in 2005 near Eulau (in Saxony-Anhalt, Germany) and dated to about 2600 BCE, tested positive for the Y-SNP marker SRY10831.2. The Ysearch number for the Eulau remains is 2C46S. The ancestral clade was thus present in Europe at least 4600 years ago, in association with one site of the widespread Corded Ware culture.[67]


In Europe, the R1a1 sub-clade is found at highest levels among peoples of Eastern European descent, with 50 to 65% among Sorbs, Poles, Russians and Ukrainians.[68][69][12] In the Baltic countries R1a1a frequencies decrease from Lithuania (45%) to Estonia (around 30%).[70] Levels in Hungarians have been noted between 20 and 60%.[71][72][12][73]

There is a significant presence in peoples of Scandinavian descent, with highest levels in Norway and Iceland, where between 20 and 30% of men are in R1a1a.[74][75] Vikings and Normans may have also carried the R1a1a lineage westward; accounting for at least part of the small presence in the British Isles.[76][77] In East Germany, where Haplogroup R1a1a reaches a peak frequency in Rostock at a percentage of 31.3%, it averages between 20 and 30%.[78]

Haplogroup R1a1a was found at elevated levels among a sample of the Israeli population who self-designated themselves as Levites and Ashkenazi Jews (Levites comprise approximately 4% of Jews). Behar reported R1a1a to be the dominant haplogroup in Ashkenazi Levites (52%), although rare in Ashkenazi Cohanim (1.3%).[69]

In Southern Europe R1a1a is not common, but significant levels have been found in pockets, such as in the Pas Valley in Northern Spain, areas of Venice, and Calabria in Italy.[79] The Balkans shows lower frequencies, and significant variation between areas, for example more than 30% in Slovenia, Croatia and Greek Macedonia, but less than 10% in Albania, Kosovo and parts of Greece.[80][72][12]

R1a is virtually composed only of the Z284 subclade in Scandinavia, which is only found in single sample of a Slovenian in Eastern Europe, where the main subclade is Z282(Z280 and M458) and there is a negligible representation of Z93 in each region other than Turkey.[44] The West Slavs and Hungarians are characterized by a high frequency of the subclade M458 and a low Z92, a subclade of Z280. Hundreds of samples of each Slovenians, and Czechs lack the Z92 subclade of Z280, while Poles, Slovaks, Croats and Hungarians only show a very low frequency of Z92.[44] The Balts, East Slavs, Serbs, Macedonians, Bulgarians and Romanians demonstrate a ratio Z280>M458 and a high, up to a prevailing share of Z92.[44] Balts and East Slavs have the same subclades and similar frequencies in a more detailed phylogeny of the subclades.[81][82] The Russian geneticist Oleg Balanovsky speculated that there is a predominance of the assimilated pre-Slavic substrate in the genetics of East and West Slavic populations, according to him the common genetic structure which contrasts East Slavs and Balts frоm other populations may suggest the explanation that the pre-Slavic substrate of the East Slavs consisted most significantly of Baltic-speakers, which at one point predated the Slavs in the cultures of the Eurasian steppe according to archaeological and toponymic references.[83]


Central Asia[edit]

In Afghanistan, R1a1a is found at 51% among the Pashtuns who are the largest ethnic group in Afghanistan, 50% among the Kyrgyz, and 30% among the Tajiks. It is less frequent among the Hazaras (7%) and the Turkic-speaking Uzbeks (18%).[84]

South Asia[edit]

In South Asia, R1a1a has often been observed with high frequency in a number of demographic groups.[38][37]

In India, high frequencies of this haplogroup is observed in West Bengal Brahmins (72%)[37] to the east, Konkanastha Brahmins (48%)[37] to the west, Khatris (67%)[1] in the north and Iyengar Brahmins (31%)[37] in the south. It has also been found in Bihar Paswan (38%) in a Schedule Caste group and several South Indian Dravidian-speaking Adivasis including the Chenchu (26%) and the Valmikis of Andhra Pradesh and the Kallar of Tamil Nadu suggesting that R1a1a is widespread in Tribal Southern Indians.[11]

Besides these, studies show high percentages in regionally diverse groups such as Manipuris (50%)[1] to the extreme North East and among Punjabis (47%)[11] to the extreme North West.

In Pakistan it is found at 71% among the Mohanna tribe in Sindh province to the south and 46% among the Baltis of Gilgit-Baltistan to the north.[1] Among the Sinhalese of Sri Lanka, 23% were found to be R1a1a (R-SRY1532) positive. [85] Hindus of Chitwan District in the Terai region Nepal show it at 69%.[86]

East Asia[edit]

The frequency of R1a1a is comparatively low among some Turkic-speaking groups including Turks, Azeris, Kazakhs, and Yakuts, yet levels are higher (19 to 28%) in certain Turkic or Mongolic-speaking groups of Northwestern China, such as the Bonan, Dongxiang, Salar, and Uyghurs.[13][87][88]

In Eastern Siberia, R1a1a is found among certain indigenous ethnic groups including Kamchatkans and Chukotkans, and peaking in Itel'man at 22%.[89]

West Asia[edit]

R1a1a has been found in various forms, in most parts of Western Asia, in widely varying concentrations, from almost no presence in areas such as Jordan, to much higher levels in parts of Kuwait, Turkey and Iran. The Shimar (Shammar) Bedouin tribe in Kuwait show the highest frequency in the Middle East at 43%.[90][91][92])

Wells 2001, noted that in the western part of the country, Iranians show low R1a1a levels, while males of eastern parts of Iran carried up to 35% R1a1a. Nasidze 2004 found R1a1a in approximately 20% of Iranian males from the cities of Tehran and Isfahan. Regueiro 2006 in a study of Iran, noted much higher frequencies in the south than the north.

A newer Study has found 20.3% R-M17* among Kurdish samples which were taken in the Kurdistan Province in western Iran, 9.7% among Mazandaranis in North Iran in the province of Mazandaran, 9.4% among Gilaks in province of Gilan, 12.8% among Persian and 17.6% among Zoroastrians in Yazd, 18.2% among Persians in Isfahan, 20.3% among Persians in Khorasan, 16.7% Afro-Iranians, 18.4% Qeshmi "Gheshmi", 21.4% among Persian Speaking Bandari people in Hormozgan and 25% among the Baloch people in Sistan and Baluchestan Province.[93]

Further to the north of these Middle Eastern regions on the other hand, R1a1a levels start to increase in the Caucasus, once again in an uneven way. Several populations studied have shown no sign of R1a1a, while highest levels so far discovered in the region appears to belong to speakers of the Karachay-Balkar language among whom about one quarter of men tested so far are in haplogroup R1a1a.[1]

Popular science[edit]

Bryan Sykes in his book Blood of the Isles gives imaginative names to the founders or "clan patriarchs" of major British Y haplogroups, much as he did for mitochondrial haplogroups in his work The Seven Daughters of Eve. He named R1a1a in Europe the "clan" of a "patriarch" Sigurd, reflecting the theory that R1a1a in the British Isles has Norse origins.

In art[edit]

Artem Lukichev created an animation based on the Bashkir epic about the Ural, which outlined the history of the clusters of haplogroup R1: R1a and R1b.[94]

Historic naming of "R1a"[edit]

The historic naming system commonly used for R1a was inconsistent in different published sources, because it changed often; this requires some explanation.

In 2002, the Y Chromosome Consortium (YCC) proposed a new naming system for haplogroups (YCC 2002), which has now become standard. In this system, names with the format "R1" and "R1a" are "phylogenetic" names, aimed at marking positions in a family tree. Names of SNP mutations can also be used to name clades or haplogroups. For example, as M173 is currently the defining mutation of R1, R1 is also R-M173, a "mutational" clade name. When a new branching in a tree is discovered, some phylogenetic names will change, but by definition all mutational names will remain the same.

The widely occurring haplogroup defined by mutation M17 was known by various names, such as "Eu19", as used in (Semino 2000) in the older naming systems. The 2002 YCC proposal assigned the name R1a to the haplogroup defined by mutation SRY1532.2. This included Eu19 (i.e. R-M17) as a subclade, so Eu19 was named R1a1. Note, SRY1532.2 is also known as SRY10831.2[citation needed] The discovery of M420 in 2009 has caused a reassignment of these phylogenetic names.(Underhill 2009 and ISOGG 2012) R1a is now defined by the M420 mutation: in this updated tree, the subclade defined by SRY1532.2 has moved from R1a to R1a1, and Eu19 (R-M17) from R1a1 to R1a1a.

More recent updates recorded at the ISOGG reference webpage involve branches of R-M17, including one major branch, R-M417.

  • More controversial is another big name he invokes: “Peter Underhill, scientist at the Department of Genetics at the Stanford University School of Medicine, is one of those at the centre of the action. Three years ago, a team of 32 scientists he led published a massive study mapping the distribution and linkages of R1a. It used a panel of 16,244 male subjects from 126 populations across Eurasia. Dr. Underhill’s research found that R1a had two sub-haplogroups, one found primarily in Europe and the other confined to Central and South Asia. Ninety-six per cent of the R1a samples in Europe belonged to sub-haplogroup Z282, while 98.4% of the Central and South Asian R1a lineages belonged to sub-haplogroup Z93. The two groups diverged from each other only about 5,800 years ago.” Note that 5,800 years ago is about the time estimated by legitimate experts in linguistics for the initial fragmentation of Proto-Indo-European. It could for instance be the time when an Indo-European-speaking population left its Indian homeland.

“Dr. Underhill’s research showed that within the Z93 that is predominant in India, there is a further splintering into multiple branches. The paper found this ‘star-like branching’ indicative of rapid growth and dispersal. So if you want to know the approximate period when Indo-European language speakers came and rapidly spread across India, you need to discover the date when Z93 splintered into its own various subgroups or lineages.” From these data about Z93, it does not follow that “Indo-European language speakers came” to India. Here you see a vivid illustration of how the interpretative framework in terms of an Aryan invasion is merely borrowed on trust from people whose bias the geneticists don’t even realize. According to Joseph: “This hypothesis was based on the erroneous assumption that R1a lineages in India had huge diversity compared to other regions, which could be indicative of its origin here. As Prof. Richards puts it, ‘the idea that R1a is very diverse in India, which was largely based on fuzzy microsatellite data, has been laid to rest’ thanks to the arrival of large numbers of genomic Y-chromosome data.” But even with the data now claimed, R1a is still more diverse in India than in Central Asia and Europe. If the former is therefore incapable of being the homeland, so are the latter. Nonetheless, our AIT activist goes full steam ahead: “Now that we know that there WAS indeed a significant inflow of genes from Central Asia into India in the Bronze Age, can we get a better fix on the timing, especially the splintering of Z93 into its own sub-lineages? Yes, we can; the research paper that answers this question was published just last year, in April 2016, titled: ‘Punctuated bursts in human male demography inferred from 1,244 worldwide Y-chromosome sequences.’ This paper, which looked at major expansions of Y-DNA haplogroups within five continental populations, was lead-authored by David Poznik of the Stanford University, with Dr. Underhill as one of the 42 co-authors. The study found ‘the most striking expansions within Z93 occurring approximately 4,000 to 4,500 years ago’.” Here we see no link with an immigration, perfectly unnecessary for a genetic differentiation. And if there was one, it apparently took place 4,500 years ago, still a thousand years before the established Aryan invasion scenario.

(2003): "Haplogroup R1a, previously associated with the putative Indo-Aryan invasion, was found at its highest frequency in Punjab but also at a relatively high frequency (26%) in the Chenchu tribe. This finding, together with the higher R1a-associated short tandem repeat diversity in India and Iran compared with Europe and central Asia, suggests that southern and western Asia might be the source of this haplogroup."[11]

M780 is concentrated in the Ganges Vally, the locus of the classic Vedic society.
  11. Qutes:
    • Sahoo et al. (2006): "... one should expect to observe dramatically lower genetic variation among Indian Rla lineages. In fact, the opposite is true: the STR haplotype diversity on the background of R1a in Central Asia (and also in Eastern Europe) has already been shown to be lower than that in India (6). Rather, the high incidence of R1* and Rla throughout Central Asian European populations (without R2 and R* in most cases) is more parsimoniously explained by gene flow in the opposite direction, possibly with an early founder effect in South or West Asia.[40]
    • Sharma et al. (2009): "A peculiar observation of the highest frequency (up to 72.22%) of Y-haplogroup R1a1* in Brahmins hinted at its presence as a founder lineage for this caste group. Further, observation of R1a1* in different tribal population groups, existence of Y-haplogroup R1a* in ancestors and extended phylogenetic analyses of the pooled dataset of 530 Indians, 224 Pakistanis and 276 Central Asians and Eurasians bearing the R1a1* haplogroup supported the autochthonous origin of R1a1 lineage in India and a tribal link to Indian Brahmins. However, it is important to discover novel Y-chromosomal binary marker(s) for a higher resolution of R1a1* and confirm the present conclusions."[3]
  12. Sengupta et al. (2006): "The widespread geographic distribution of HG R1a1-M17 across Eurasia and the current absence of informative subdivisions defined by binary markers leave uncertain the geographic origin of HG R1a1-M17. However, the contour map of R1a1-M17 variance shows the highest variance in the northwestern region of India [...] The question remains of how distinctive is the history of L1 relative to some or all of R1a1 and R2 representatives. This uncertainty neutralizes previous conclusions that the intrusion of HGs R1a1 and R2 from the northwest in Dravidian-speaking southern tribes is attributable to a single recent event. [R1a1 and R2] could have actually arrived in southern India from a southwestern Asian source region multiple times, with some episodes considerably earlier than others. Considerable archeological evidence exists regarding the presence of Mesolithic peoples in India (Kennedy 2000), some of whom could have entered the subcontinent from the northwest during the late Pleistocene epoch. The high variance of R1a1 in India (table 12), the spatial frequency distribution of R1a1 microsatellite variance clines (fig. 4), and expansion time (table 11) support this view."[37]

  83. П, Балановский О. "Генофонд Европы" (in русский). KMK Scientific Press. Прежде всего, это преобладание в славянских популяциях дославянского субстрата — двух ассимилированных ими генетических компонентов – восточноевропейского для западных и восточных славян и южноевропейского для южных славян...Можно с осторожностью предположить, что ассимилированный субстратмог быть представлен по преимуществу балтоязычными популяциями. Действительно, археологические данные указыва ют на очень широкое распространение балтских групп перед началом расселения славян. Балтскийсубстрату славян (правда, наряду с финно-угорским) выявляли и антропологи. Полученные нами генетические данные — и на графиках генетических взаимоотношений, и по доле общих фрагментов генома — указывают, что современные балтские народы являются ближайшими генетически ми соседями восточных славян. При этом балты являются и лингвистически ближайшими род ственниками славян. И можно полагать, что к моменту ассимиляции их генофонд не так сильно отличался от генофонда начавших свое широкое расселение славян. Поэтому если предположить,что расселяющиеся на восток славяне ассимилировали по преимуществу балтов, это может объяснить и сходство современных славянских и балтских народов друг с другом, и их отличия от окружающих их не балто-славянских групп Европы...В работе высказывается осторожное предположение, что ассимилированный субстрат мог быть представлен по преимуществу балтоязычными популяциями. Действительно, археологические данные указывают на очень широкое распространение балтских групп перед началом расселения славян. Балтский субстрат у славян (правда, наряду с финно-угорским) выявляли и антропологи. Полученные в этой работе генетические данные — и на графиках генетических взаимоотношений, и по доле общих фрагментов генома — указывают, что современные балтские народы являются ближайшими генетическими соседями восточных славян.<templatestyles src="Module:Citation/CS1/styles.css"></templatestyles>
