It clearly bears an astonishing resemblance to R1b in Europe and SW Asia. It would be neccessary to also assume some like with the R1* and R* phases to fully explain its distribution in Asia.
One thing it really does not fit is R1a. That should not really be the case given both descendant from R1. It is clear to me that one or the other has lost the original R autosomal signature. It looks most likely that current Slavic area R1a is very low in Gedrosia. The lower traces in the urals and south Ukraine may be a faint echo of a former stronger presence. It seems to me however that what is largely now the Slavic zone does not have much Gedrosia and at some point in its history the Slavic R1a people mixed in with others to the point that their autosomal DNA was left with very little of its original pattern.
Anyway, I realise there are other options but I think this pattern needs explained and if nothing else does tell us something about R1a and b's diverging histories.
