Not only is the skeletal evidence nil, but "if invasions of exotic races had taken place by Aryan hordes, we should encounter obvious discontinuities… - Kenneth A. R. Kennedy

Our multivariate approach does not define the biological identity of an ancient Aryan population, but it does indicate that the Indus Valley and Gandhära peoples shared a number of craniometric, odontometric and discrete traits that point to a high degree of biological affinity. Evidence of demographic disconti­nuities is present in our study, but the first occurs between 6000 and 4500 B.C. (a separation between the Neolithic and Chalcolithic populations of Mehrgarh) and the second is after 800 B.C., 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 o f demographic disruptions in the north­ western sector o f 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.

[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.”

Kennedy also refers to a “biological continuum [... with] the modern populations of Punjab and Sind,” agreeing in this with earlier skeletal studies by several Indian experts, who had found little difference between Harappan skeletons and present-day populations in those regions (also in Gujarat).
