Article by Bahata Ansumali Mukhopadhyay

Ancestral Dravidian languages in Indus Civilization: ultraconserved Dravidian tooth-word reveals deep linguistic ancestry and supports genetics 

reveals that the IVC population spoke a proto-Dravidian language. This research corroborates the findings of David Reich et al. that the IVC population were a mixture of Iranian migrants from the Zagros and the local Onge-related people. They could not have spoken Sanskrit because this language was brought by the Steppe population Yamnaya / Sinthasta and were unrelated to IVC.
