[the idea of an Aryan invasion of India in the second millennium BCE] has recently been challenged by archaeologists, who ― along with linguists ― are best qualified to evaluate its validity. Lack of convincing material (or osteological) traces left behind by the incoming Indo-Aryan speakers, the possibility of explaining cultural change without reference to external factors and ― above all ― an altered world-view (Shaffer 1984) have all contributed to a questioning of assumptions long taken for granted and buttressed by the accumulated weight of two centuries of scholarship.... [the perspective offered by archaeology], "that of material culture […] is in direct conflict with the findings of the other discipline claiming a key to the solution of the ‘Aryan Problem’, linguistics" ...Archaeologists and anthropologists... [like] Jim G. Shaffer and Diane A. Lichtenstein, who “stress the indigenous development of South Asian civilization from the Neolithic onwards, and downplay the role of language in the formation of (pre-modern) ethnic identities”; J. Mark Kenoyer, who “stresses that the cultural history of South Asia in the 2nd millinnium B.C. may be explained without reference to external agents”, and Kenneth A.R. Kennedy, who concludes “that while discontinuities in physical types have certainly been found in South Asia, they are dated to the 5th/4th, and to the 1st millennium BC, respectively, too early and too late to have any connection with ‘Aryans’.”

For example, Erdosy (1995) noted that cremation was pretty common in 2000 BCE Balochistan (Penano Ghundai II, Mughal Ghundai III, Dabar Kot, Mehi, Sutkagen-dor) but very rare in Central Asia: “If anything, on present evidence, cremations appear to have originated in the Indo-Iranian Borderlands and spread northwest (and southeast) thence, against the grain of postulated movements of Indo-Aryan speakers”.

Evidence for the characterization of Dasas and Dasyus as black is tenuous in the extreme.... Even apparently clear indications of historical struggles between dark aborigines and Arya conquerors turn out to be misleading.... [The Dasas and Dasyus] appear to be demonic rather than human enemies.... It is a cosmic struggle which is described in detailed accounts that are consistent with one another.”
