One of the more curious aspects of Indo-Aryan history is the case of the Y-DNA lineage R-Z93>Z94>Y3>Y2>Y27>L657.
While this is overwhelmingly dominant among R1a lineages in India outside NW, it is very rare in modern Steppe pops and aDNA

On the other hand, the R-Z93>Z94>Z2124 lineage is ubiquitous in aDNA (including the Sintashta). Its also common in modern Steppe pops and NW-India.
This paradox merits more attention.
More importantly, does this disprove the theory of Steppe origins of Indo-Aryans ?

Exploring further with admixture dating:
1) Using WEHG instead of Steppe_MLBA to date admixture of Indo-Iranians and IVC pops in Swat samples
Very similar date of 1613 BC instead of 1671 BC using Steppe_MLBA !
(1/6)
Earlier date with Steppe_MLBA is likely due to earlier admixture of IVC with Anatolia_N from BMAC or West Asia.
Either way, it was very marginal compared to the Anatolia_N received from Steppe_MLBA.

The male-biased migrations of Indo-Europeans across Eurasia during the Bronze Age is well known.
But this 2021 paper explores possible Steppe female migrations into India through mtDNA analysis.
A short thread of my takeaways (as a layman):
nature.com/articles/s4143…1) Haplogroups H2a1a,J1b1a1,U4a1 and W3a1 are the genetic legacy of the Indo-Iranian migration into India.
For instance, U4a1 and W3a1 are present in BA Yamnaya, IA Swat valley as well as in modern populations in E-Europe, C-Asia and India and Thailand. (see A in following pic)

FAQ thread on the Aryan Invasion Theory (AIT) and assimilating it into the Hindu narrative.
Earlier date with Steppe_MLBA is likely due to earlier admixture of IVC with Anatolia_N from BMAC or West Asia.
