Nothing, in the present state of archaeological research ... enables us to reconstruct convincingly invasions that could be clearly attributed to Ary… - Jean-François Jarrige

Despite inviting linguists to reconsider the northern steppe hypothesis in favor of the southern route, it can be inferred from Jarrige and Hassan, as from the work of a number of archaeologists considering the problem of Indo-Aryan origins, that the Indo-Aryan- locating project exists solely due to linguistic exigencies: The development of original but closely interrelated cultural units at the end of the third and the beginning of the second millennium cannot be explained just by the wandering of a single group of invaders. The processes were obviously multidirectional in regions with strong and ancient cultural traditions. This does not preclude the fact that movement of population and military expeditions . . . may have played an important historical part but, as far as archaeology is concerned, there is nothing to substantiate a simplistic model of invasion to account for the complex economic and cultural phenomena manifest at the end of the third millennium in the regions between Mesopotamia and the Indus Valley.

Although basic similarities exist, linking Mehrgarh with comparable Levantine and Zagrosian aceramic neolithic groups, “...they are sufficiently general to discount straightforward diffusion among communities that otherwise preserved their own, highly individual characteristics” (Jarrige 1991: 40).
