Two conclusions may be drawn from the archaeological data. First, there is no connection between PGW culture and that of the Aryans. Second, if the "Aryan" concept is to have any cultural meaning, then such a culture (PGW) had an indigenous South Asian origin within the protohistoric cultures of the Ganga-Yamuna region. There was no invasion from the West. The current archaeological evidence suggests that the original reconstruction indicating the occurrence of an Indo-Aryan invasion mistakenly associated linguistic change with the migration of peoples. Linguistic changes and affiliations are brought about by a complex series of cultural processes, many of which do not involve the physical movements of social groups.

While lacking fullest data, there is a growing consensus that the Harappan culture originated as a result of local cultural developments. "Mesopotamian" inventions are not needed to explain it.

The Mehrgarh excavations near Sibri, Pakistan, changed our understanding of the origins of food production - the use of domesticated plants and animals in a neolithic context - in South Asia. Previously, food production and the entire “village way o f life” were perceived as a single complex, diffused from the W est sometime after 5000 B.C. They, in turn, were followed by the “idea” of civilisation only a few millennia later, then by the Aryan, Greek, Muslim and British invasions. The acceptance of one incidence of cultural diffusion/invasion made the others seem that much more reasonable.
