Rakhigarhi samples from the Indus Valley Civilisation will support the conclusions of Narasimhan et al. (2018)

New article on The Caravan, Indus Valley People Did Not Have Genetic Contribution From The Steppes: Head Of Ancient DNA Lab Testing Rakhigarhi Samples, by Hartosh Singh Val.

Niraj Rai, head of the DNA Laboratory where the samples from the Harappan site of Rakhigarhi in Haryana are being analysed, has this to say:

It will show that there is no steppe contribution to the Indus Valley DNA.

The Indus Valley people were indigenous, but in the sense that their DNA had contributions from near eastern Iranian farmers mixed with the Indian hunter-gatherer DNA, that is still reflected in the DNA of the people of the Andaman islands.

The Rakhigarhi study provides direct evidence for the claims of a paper published in preprint on bioRxiv in March 2018, which outlines a comprehensive model for the settlement of different populations within the subcontinent.

Rai had earlier told Open magazine that the male:

Y chromosome R1a genetic marker is missing in the Rakhigarhi sample.

Commenting on other hypotheses:

any model of migration of Indo-Europeans from South Asia simply cannot fit the data that is now available.

The paper based on the examination of the Rakhigarhi samples will soon be published on bioRxiv.
