Haplogroup R1a (R-M420), is a human Y-chromosome DNA haplogroup which is distributed in a large region in Eurasia, extending from Scandinavia and Central Europe to Central Asia, southern Siberia and South Asia. [3] [2]

History and description of Haplogroup R1a (Y-chromosomal DNA) and its subclades. Haplogroup R1a is the dominant paternal lineage in Northeast Europe and southern Central Asia. It was diffused around Eurasia by the Indo-Aryans and Balto-Slavic people.

R1a* 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 .

One subclade of haplogroup R1b (especially R1b1a2), is the most common haplogroup in Western Europe and Bashkortostan , while a subclade of haplogroup R1a (especially haplogroup R1a1) is the most common haplogroup in large parts of South Asia, Eastern Europe, Central Asia, Western China, and South Siberia.

An analysis of the Hume DNA Project has provided conclusive evidence that the Scottish philosopher, historian and economist David Hume (1711-1776) belonged to haplogroup R1a-Z284 > S4458 > S5301 > S5153 > L448 > CTS4179. This subclade is …

Mar 26, 2014 · Whole Y-chromosome sequence analysis of eight R1a and five R1b individuals suggests a divergence time of ∼25 000 (95% CI: 21 300–29 000) years ago and a coalescence time within R1a-M417 of ∼...

This map was computed by adding paternal lineages associated with the diffusion Slavic peoples from the Iron Age onwards. These include Y-DNA haplogroups I2a1b-CTS10228, R1a-CTS1211, R1a-Z92 and some branches R1a-M458.

Family Tree DNA's haplogroup description of R1a: R1a - The R1a lineage is believed to have originated in the Eurasian Steppes north of the Black & Caspian Seas. This lineage is thought to descend from a population of the Kurgan culture, known for …

The two most common descendant clades of R1 are R1a and R1b. R1a-M420 is believed to have arisen on the Eurasian Steppe or the Indus Valley, and today is most frequently observed in eastern Europe and in western and central Asia.
