"It could be argued that the IAs developed their complex but secure system of oral transmission while on the move. ... But, if that were so, what would the IAs (or Indo- Iranians, since they were one people, according to the AIT) be transmitting and thus preserving? Their sacred RV was composed in the Saptasindhu. If they had developed their superb system while on the move, then they would have at least a few tales of their adventurous trekking and these would have been embodied in the hymns of the RV."
