As Razib mentions: "Basically, the individual(s) they got DNA out of did not have any Eurasian steppe ancestry."


“We did some analysis to figure out the exact date of the admixture. We have prepared a model in which all these stats fit together very tightly and that model suggests the Central Asian admixture happened about 1500-1000 BC…. Significant mixing happened around 1000 BC, also at 800 BC and 600 BC.”

I am not sure what Rai means by this:


“The Rakhigarhi samples have a significant amount of ‘Iranian farmer’ ancestry,” says Rai. “In India’s present-day population, only the south Indians have Iranian farmer ancestry. You won’t find Iranian farmer DNA in the north Indian population.”

Hmm, so not all "Iran N" is Iranian farmer? This study should be interesting.

"That is, the Swat Valley samples show admixture and genetic change after 1200 BC."

They don't show admixture and genetic change after, but the samples that were tested are after. Many sites show occupation as early as 3000 BC. So unless we have those earlier ones tested we would not know when the change occurred.

The Y-markers (E, J, H, G, L, R2, etc) in protohistoric IA Swat are not steppe markers expect perhaps one Q1b2. So was it a female based migration? - highly unlikely.
