A diffusion or migration of a culturally complex ‘Indo-Aryan‘ people into South Asia is not described by the archaeological record. - Jim G. Shaffer

Since stamp seals were not available to everyone in a social group, and because their inscriptions most likely reflect titles and/or personal names, it is reasonable to conclude that cattle were invested with social importance and cultural identity. Moreover, if seals were also a marriage talisman, as Fairservis argues, they suggest that cattle constituted a wealth category associated with forging important social relationships such as marriage. Furthermore, if cattle, as wealth, provided access to reproductive sources, they were probably also avenues to establishing, maintaining or breaking other important social, economic, political and religious relationships.

Although the use of cattle as important cultural wealth declined in the first millennium B.C., their religious status remained high, or intensified, providing an im portant cultural link between the protohistoric and Early Historic Periods

It is currently possible to discern cultural continuities linking specific prehistoric social entities in South Asia into one cultural tradition. This is not to propose social isolation nor deny any outside cultural influence. Outside cultural influences did affect South Asian cultural development in later, especially historic, periods, but an identifiable cultural tradition has continued, an Indo-Gangetic Cultural Tradition linking social entities over a time period from the development of food production in the seventh millennium BC to the present.
