Further, a classification of Harappan sites as early, mature and late happens to align well with the history of when the river was flowing and when it started shifting course as established by the geological evidence. Mature sites are found along the original course and as it starts drying up, late sites show up further east closer to the Yamuna. Given the association of the Harappan sites with the Sarasvati river's course, Danino (and many other archeologists) argue that if the civilization should be named after any river(s), it should be called the Indus-Sarasvati civilization. Or more neutrally, the Harappan civilization after the first discovered site.
So, we have the Vedic Aryans living close to the Sarasvati witnessing its robust flows and Harappan sites have been found in exactly those locations. If the Vedic Aryans arrived in India 500 years after the decline of the Harappan civilization in the 2nd millennium BCE as per the prior belief, then they could not have seen the Sarasvati in full flow since the geological evidence suggests that it had dried up by then. This is actually the starting point for Danino's elaborate argument that the Vedic society and latter day Indian civilization is nothing but a continuation of the Harappan civilization. The Harappans did not vanish. They just moved eastward as the rivers shifted courses and settled eventually in the Gangetic plain. This makes the Indian civilization the longest running continuous civilization in history as per Danino and others who share this thinking (this may just explain the 1.2 billion).
If the Harappans are closely associated with the Vedic Aryans, that seemingly contradicts the theory put forth by I. Mahadevan and Asko Parpola that the Harappan script might be a written form of a proto-Dravidian language. Or does it? Only if you equate languages with civilizations. May be there were proto-Dravidian speakers living among the Harappans (Vedic Aryans). There is a lot of other evidence that suggests the Harappans themselves were a very diverse loosely federated society with no central control.
The book continues with an elaborate discussion of the Harappan civilization, and how, many of their traditions show up in modern day cities along the Gangetic plain. More on that later.
