This timing and spread align with simultaneous expansions linked to the Andronovo horizon, though the exact founder event for L657 in India could indicate either its formation within the subcontinent or a rare lineage survival from the Steppe that left little trace there. To clarify, Z93 itself is predominantly a Steppe lineage, but in India, mostly its descendant subclades (like L657) are present, reflecting complex migration and local expansion patterns rather than a simple direct migration of all of Z93. So yes, the key R1a lineages in India do trace back to Steppe origins but likely arrived in multiple waves and established distinct populations locally afterward.
