[The ancient Harappans] are not markedly different in their skeletal biology from the present-day inhabitants of Northwestern India and Pakistan"... … - Kenneth A. R. Kennedy

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.

Not only is the skeletal evidence nil, but "if invasions of exotic races had taken place by Aryan hordes, we should encounter obvious discontinuities in the prehistoric skeletal record that correspond with a period around 1500 BC." Whatever discontinuities do occur in the record are either far too late or far too early (Kennedy 1995, 58). These discontinuities were taken from a further study undertaken on the skeletal remains in the Harappan phase "Cemetery R37" (Hemphill et al. 1991). The results of this survey showed two periods of discontinuities: the first occurs during the period between 6000 and 4500 B.C.E. between the Neolithic and Chalcolithic inhabitants of Mehrgarh, and the second at some point before 200 B.C.E. (but after 800 B.C.E.), which is visible in the remains at Sarai Khola (200 B.C.E.). Clearly, neither of these biological discontinuities corresponds with the commonly accepted period for Indo-Aryan intrusions. The Aryans have not been located in the skeletal record.

These developments in the biological sciences are o f little interest to our colleagues in other research areas for whom the Aryan presence remains a vital issue. A t best, the skeletal biologist familiar with the record of human remains from South A sia can respond by asking “How could one recognize an Aryan, living or dead, when the biological criteria for Aryanness are non-existent?”
