Nag,
They cannot show a geographical cline for R in the direction that they so desperately want. Their only alternative is to show a heirarchial cline in India itself which buttresses the argument that there is a social (caste) heirarchy in india - which can only be explained by an ait type scenario. This is a patently theological assumption about there being "religion" in India with certain sections acting as the agents of historical, religious (and also linguistic) change.
