"[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’.”"
