Description
R1 is the parent clade of R1a and R1b — the two most widespread Y-DNA haplogroups in Europe and South Asia. R1 likely originated in Central Asia during the last glacial maximum and subsequently expanded with post-glacial population movements and, later, the Bronze Age steppe migrations. The M173 mutation defines R1.
Interesting Fact
The split between R1a and R1b occurred approximately 25,000–22,000 years ago, yet today these two branches dominate entirely different geographic regions — R1b in Western Europe, R1a in Eastern Europe and South Asia — a divergence shaped by Bronze Age migrations thousands of years after the initial split.
