The genetic divergence of R1a (M420) is estimated to have occurred 25,000 [2] 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".

Haplogroup R1, or R-M173, is a Y-chromosome DNA haplogroup. A primary subclade of Haplogroup R (R-M207), it is defined by the SNP M173. The other primary subclade of Haplogroup R is Haplogroup R2 (R-M479). Males carrying R-M173 in modern populations appear to comprise two subclades: R1a and R1b, which are found mainly in populations native to ...
Haplogroup R (mtDNA) For the Y-chromosome haplogroup, see Haplogroup R (Y-DNA). Haplogroup R is a widely distributed human mitochondrial DNA (mtDNA) haplogroup. Haplogroup R is associated with the peopling of Eurasia after about 70,000 years ago, and is distributed in modern populations throughout the world outside of sub-Saharan Africa. [ 4 ]
Haplogroup R1a is one of the major classifications (called clades) of Y-chromosome types found in human male lines.It is widespread all across Eurasia.Many sample studies therefore carry information on the incidence of R1a and/or its subclassifications, in particular the dominant branching line represented by the haplogroups R1a1 and R1a1a.
While R1a originated c. 22,000 [56] to 25,000 [74] years ago, its subclade M417 (R1a1a1) diversified c. 5,800 years ago. [74] The distribution of M417-subclades R1-Z282 (including R1-Z280) [75] in Central and Eastern Europe and R1-Z93 in Asia [74] [75] suggests that R1a1a diversified within the Eurasian Steppes or the Middle East and Caucasus ...
R1 has two descendant subclades: R1a and R1b. R1a is associated with the proto-Indo-Iranian and Balto-Slavic peoples, and is now found predominantly in Central Asia, South Asia, and Eastern Europe. Haplogroup R1b is the dominant haplogroup of Western Europe and is also found sparsely distributed among various peoples of Asia and Africa.
v. t. e. A haplotype is a group of alleles in an organism that are inherited together from a single parent, [1][2] and a haplogroup (haploid from the Greek: ἁπλοῦς, haploûs, "onefold, simple" and English: group) is a group of similar haplotypes that share a common ancestor with a single-nucleotide polymorphism mutation. [3]
Haplogroup R (Y-DNA) Haplogroup R, or R-M207, is a Y-chromosome DNA haplogroup. It is both numerous and widespread amongst modern populations. Some descendant subclades have been found since pre-history in Europe, Central Asia and South Asia. Others have long been present, at lower levels, in parts of West Asia and Africa.
