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.

Despite the early misgivings of some scholars about such a correlation between language and race and the circular nature of many of the arguments, the concept of a common linguistic, cultural, biological, and historical heritage linking European and Indian peoples became internationally accepted as more fact than theory. Based on linguistic reconstructions, the prehistoric to historic chronologies of Europe and India were interpreted as reflecting various invasions of Indo-European or Indo-Aryan peoples who possessed a common cultural heritage, albeit remote. For Europe, this concept ultimately resulted in the disaster of the Third Reich, whereas in South Asia, the concept of Indo-Aryan peoples played a quite different cultural role.

The gradual reduction in size, a phenomenon associated with domesti­cation, and the occurrence o f wild progenitors in earlier levels, indicate that the domestication o f these animals was also a local process.... Although similar species were domesticated elsewhere, the pattern in which hum an actors arranged them in South Asia was distinctive to the region.
