Witzel frequently refers to the references to armaka, "ruins", in the RV, as evidence that the RV is later to the desolation of the Indus cities... In any case, the word armaka, so frequently referred to in the post-RV literature, is found in the RV only in one late hymn in a Late Book: in I.133.3. The Early and Middle Books, and even much of the Late Books, are totally ignorant about these ruins.

“The modern Indo-Aryan languages are not descendants of the Rigvedic dialects, but of other dialects which were contemporaneous with the Rigvedic dialects, but which belonged to a different section of Indo-European speech (the Inner Indo-European section). The Vedic dialects died away in the course of time, and their speech area [….] was taken over by the Inner Indo-European dialects. But long before they died away, the Vedic dialects had set in motion a powerful wave of a cult movement which covered the entire nation in its sweep. This Vedic cult also finally gave way to the local pan-Indian religion of the Inner-Indo-Europeans and Dravidian-language speakers, but continued to remain in force as the elite layer of this pan-Indian religion” (TALAGERI 1993a:230).

Other scholars, when they deign to notice the evidence in the PurANas in respect of the indigenous origin of the Aryans and their expansion outside India, tend to dismiss this evidence as irrelevant on the ground that it is allegedly contradictory to the evidence of the Rigveda.
