Chakrabarti (1977b) finds that they "may more satisfactorily be explained as nothing more than what they apparently are: isolated objects finding their way in through trade or some other medium of contact, not necessarily any population movement of historic magnitude" (31). He notes that prior to die artificial boundaries demarcated by the British, the southern part of the Oxus, eastern Iran, Afghanistan, and the Northwest of the subcontinent all constituted an area with significant economic and political interaction throughout the ages—a sphere of activity distinct from the Iranian heartland to the west and Gangetic India to the east. In such an economic and geopolitical zone, "any new significant cultural innovation in any one area between the Oxus and the Indus is likely to spread rapidly to the rest of this total area" (31). As far as he is concerned, "the archaeological data from the Indus system and the area to its west . . . which have been interpreted as different types of diffusion from a vague and undefined West Asia are no more than the indications of mutual contact between the geographical components of this interaction sphere" (35).
