If invasions o f exotic races had taken place by Aryan hordes, we should encounter obvious discontinuities in the prehistoric skeletal record that co… - Kenneth A. R. Kennedy

K. Kennedy (1984), however, who was able to examine all three hundred skeletons that had been retrieved from the Indus Valley Civilization, found that the ancient Harappans "are not markedly different in their skeletal biology from the present-day inhabitants of Northwestern India and Pakistan" (102). He considers any physical variations in the skeletal record to be perfectly normal for a metropolitan setting and consistent with any urban population past or present (103). As far as he is concerned, the polytypism in the South Asian record represents an "overlap of relatively homogeneous tribal and outcaste groups and their penetration into villages, then into urban environments of more heterogeneous people." There is no need to defer to intruding aliens for any of this: "This dynamic rather than mass migration and invasions of nomadic and warlike peoples better accounts for the biological constitutions of those earlier urban populations in the Indus valley." Here, again, we encounter the same objections raised repeatedly by South Asian archaeologists: "Of the Aryans, we must defer to literary and linguistic scholars in whose province lies the determination of the arrival and nature of the linguistic phenomenon we call the Aryans. . . . But archaeological evidence of Aryan- speaking peoples is questionable and the skeletal evidence is nil" (104).

[Kenneth A.R. Kennedy reaches similar conclusions from his physical-anthropological data:] “Evidence of demographic discontinuities is present in our study, but the first occurs between 6000 and 4500 BC (a separation of the Neolithic and Chalcolithic populations of Mehrgarh) and the second is after 800 BC, the discontinuity being between the peoples of Harappa, Chalcolithic Mehrgarh and post-Harappan Timargarha on the one hand and the late Bronze Age and early Iron Age inhabitants of Sarai Khola on the other. In short, there is no evidence of demographic disruptions in the northwestern sector of the subcontinent during and immediately after the decline of the Harappan culture. If Vedic Aryans were a biological entity represented by the skeletons from Timargarha, then their biological features of cranial and dental anatomy were not distinct to a marked degree from what we encountered in the ancient Harappans.”

With closest biological affinities outside the Indus Valley to the inhabitants of Tepe Hissar 3 (3000–2000 BC), these biological data can be interpreted to suggest that peoples to the west interacted with those in the Indus Valley during this and the preceding proto-Elamite period and thus may have influenced the development of the Harappan civilization. The second biological discontinuity exists between the inhabitants of Harappa, Chalcolithic Mehrgarh, and post-Harappa Timarghara on one hand and the Early Iron Age inhabitants of Sarai Khola on the other... The Harappan Civilization does indeed represent an indigenous development within the Indus Valley, but this does not indicate isolation extending back to Neolithic times. Rather, this development represents internal continuity for only 2000 years, combined with interactions with the West and specifically with the Iranian Plateau.
