This study shall have to demonstrate then in what ways the prior study was wrong to give such a differing result, although this may be part of it:
"Recent claims for a linkage of haplogroups J2, L, R1a, and R2 with a contemporaneous origin for the majority of the Indian castes' paternal lineages from outside the subcontinent are rejected, although our findings do support a local origin of haplogroups F* and H. "
-Majority of the Indian castes' paternal lineage- was never part of what was claimed in the other study, which affirmed an affinity chiefly amongst the upper castes. Intermixing lower-castes which were demonstrated to have far less of connection would only serve to muddy the connections.
