I am not an expert but I do am a member of a message board where people discuss population genetics in a neutral and scientific way. The knowledgeable people there agree on one thing that Narshimmhan got that one thing wrong, we do have BMAC ancestry. Steppe MLBA people are thought to have trading relations with them and possibly admired with them too. That is one of the possible explanations of Jatts having high frequency of L1a2 (BMAC specific subclades) despite having highest Steppe levels in India.This appears to be based on the model where Andronovo people migrated to BMAC and mixed with local population. Later these fellows migrated into SWAT valley and further in.
Which is contrary to narsimham paper that concluded BMAC has negligible contribution to Indian ancestry. So from where did the high steppe ancestry in certain groups like rors and Jats come from.
Either directly from Andronovo or later migrations or they could very well be a part of Harappan population.
I mean at its peak IVC had 5 million inhabitants. How many skeletons unearthed ..... Around 1000 ..... How many have been successfully analysed....only 1.
Now witzel is talking about waves of Indo-Iranian migrations between 2000bce-1500bce and Indo-Aryans to 1500bce.
They are even calling Sinauli as a proof of Indo Iranian migration.
