Origins


R1a origins

The split of R1a (M420) is computed to c. 22,000 or 25,000 years ago, which is the time of the last glacial maximum. A 2014 study by Peter A. Underhill et al., using 16,244 individuals from over 126 populations from across Eurasia, concluded that there was "a compelling case for the Middle East, possibly near present-day Iran, as the geographic origin of hg R1a". The ancient DNA record has shown the first R1a during the Mesolithic in

Diversification of R1a1a1 (M417) and ancient migrations

According to , the downstream R1a-M417 subclade diversified into Z282 and Z93 circa 5,800 years ago "in the vicinity of Iran and Eastern Turkey". Even though R1a occurs as a Y-chromosome haplogroup among various languages such as Slavic and Indo-Iranian, the question of the origins of R1a1a is relevant to the ongoing debate concerning the of the

, consistent with multiple waves of arrival." According to Martin P. Richards, co-author of , the prevalence of R1a in India was "very powerful evidence for a substantial Bronze Age migration from central Asia that most likely brought Indo-European speakers to India."


Proposed South Asian origins

Kivisild et al. (2003) have proposed either South or West Asia, while see support for both South and Central Asia. Sharma et al.(2009) showcased the existence of R1a in India beyond 18,000 years to possibly 44,000 years in origin. South Asian populations have the highest STR diversity within R1a1a, and subsequent older

datings, and R1a1a is present among both higher ( Brahmin) castes and lower castes, although the frequency is higher among Brahmin castes. Nevertheless, the oldest TMRCA datings of the R1a haplogroup occur in the Saharia tribe, a scheduled caste of the Bundelkhand region. From these findings some researchers have concluded that R1a1a originated in South Asia, excluding a more recent, yet minor, genetic influx from Indo-European migrants in northwestern regions such as Afghanistan, Balochistan, Punjab, and Kashmir. However, this diversity, and the subsequent older TMRCA-datings, can also be explained by the historically high population numbers, which increases the likelihood of diversification and microsatellite variation. According to Sengupta et al. (2006), " 1a1 and R2could have actually arrived in southern India from a southwestern Asian source region multiple times." However, Sengupta also described in this article: This suggests that the origins of paternal haplogroup R1a point to the Indian subcontinent and not Central Asia.


Proposed Yamnaya origins

David Anthony considers the Yamnaya culture to be the Indo-European Urheimat. According to , a massive migration from the Yamnaya culture northwards took place c. 2,500 BCE, accounting for 75% of the genetic ancestry of the
Corded Ware culture The Corded Ware culture comprises a broad archaeological horizon of Europe between ca. 3000 BC – 2350 BC, thus from the late Neolithic, through the Copper Age, and ending in the early Bronze Age. Corded Ware culture encompassed a ...
, noting that R1a and R1b may have "spread into Europe from the East after 3,000 BCE". Yet, all their seven Yamnaya samples belonged to the R1b-M269 subclade, but no R1a1a has been found in their Yamnaya samples. This raises the question where the R1a1a in the Corded Ware culture came from, if it was not from the Yamnaya culture. According to Marc Haber, the absence of haplogroup R1a-M458 in Afghanistan does not support a Pontic-Caspian steppe origin for the R1a lineages in modern Central Asian populations. According to

However, according to , steppe pastoralists are a likely source for R1a in India.


Phylogeny

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 such as "R1a1" in relatively recent but not the latest literature).

R1a1 is defined by SRY1532.2 or SRY10831.2 (understood to always include SRY10831.2, M448, L122, M459, and M516). This family of lineages is dominated by M17 and M198. In contrast,

The following SNPs are associated with R1a1a:

R1a1a1 (R-M417) is the most widely found subclade, in two variations which are found respectively in Europe (R1a1a1b1 (R-Z282) ( 1a1a1a*(R-Z282) (Underhill 2014)) and Central and South Asia (R1a1a1b2 (R-Z93) ( 1a1a2*(R-Z93) Underhill 2014)).


R-Z282 (R1a1a1b1a) (Eastern Europe)

This large subclade appears to encompass most of the R1a1a found in Europe. * R1a1a1b1a 1a1a1a* (Underhill (2014))(R-Z282*) occurs in northern Ukraine, Belarus, and Russia at a frequency of c. 20%. * R1a1a1b1a3 1a1a1a1 (Underhill (2014))(R-Z284) occurs in Northwest Europe and peaks at c. 20% in Norway. * R1a1a1c (M64.2, M87, M204) is apparently rare: it was found in 1 of 117 males typed in southern Iran.

R-L260 (R1a1a1b1a1a)

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 . In 2010 it was verified to be a haplogroup identified by its own mutation (SNP). It apparently accounts for about 8% of Polish men, making it the most common subclade in Poland. Outside of Poland it is less common. In addition to Poland, it is mainly found in the Czech Republic and Slovakia, and is considered "clearly West Slavic". 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.

and Kerman in eastern Iran, but they did not find any member of this haplogroup in a sample of 25 Kurds collected in the province of Kermanshah in western Iran. Further to the north of these Western Asian 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 Karachay-Balkar (, ), or Mountain Turkic (, ), is a Turkic language spoken by the Karachays and Balkars in Kabardino-Balkaria and Karachay–Cherkessia, European Russia, as well as by an immigrant population in Afyonkarahisar Province, Turkey. I ...
among whom about one quarter of men tested so far are in haplogroup R1a1a.


Historic naming of R1a

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 The Y Chromosome Consortium (YCC) was a collection of scientists who worked toward the understanding of human Y chromosomal phylogenetics and evolution. The consortium had the following objectives: web resources that communicate information relati ...
(YCC) proposed a new naming system for haplogroups , which has now become standard. In this system, names with the format "R1" and "R1a" are "

" 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 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 The discovery of M420 in 2009 has caused a reassignment of these phylogenetic names.( and ) 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.
