Description
Haplogroup R is the parent of R1 (which contains R1a and R1b, dominant across Europe and South Asia) and R2 (found mainly in South Asia and Central Asia). R likely originated in Central Asia during the Upper Paleolithic and expanded dramatically with the Bronze Age steppe migrations. It is the most numerically dominant Y-DNA macro-haplogroup in Eurasia today.
Interesting Fact
R1a and R1b together are carried by an estimated 600–700 million men, making haplogroup R arguably the most successful paternal lineage radiation in the last 30,000 years of human history.
