Do then the proponents of the ‘Harappan = Dravidian’ equation expect us to believe that the urban Harappans, on being sent away to South India, shed away overnight their urban characteristics and took to a Stone Age way of living?Again, it has been observed all over the world that even if the original inhabitants are pushed out of an area, some of the rivers, mountains and towns in that area continue to bear the original names.Because of Max Muller’s fatwa that the Vedas were not earlier than 1200 BC, it was argued that this civilization could not be associated with the Vedic people.Since the only other major language spoken on the subcontinent was the Dravidian it was but natural at that point of time to assume that the Dravidian‑speakers were its authors.The Aryan invasion theory was not based on true archaeological, linguistic and ethnological evidence.Later research has either discredited this theory by providing new evidences that combined with the earlier evidence makes other explanations more likely.
On the other hand, what we do have in South India about that time is a neolithic culture.
One of the most controversial ideas about Hindu history is the Aryan Invasion Theory. Max Muller in 1848, traces the history of Hinduism to the invasion of India’s indigenous people by lighter skinned Aryans around 1500 BCE.
The theory was reinforced by other research over the next 120 years, and became the accepted history of Hinduism, not only in the West but in India.
Since the Rigveda refers to Indra as puramdara (destroyer of forts), he jumped at the idea that there was an ‘Aryan invasion’ which destroyed the Harappan Civilization, and the latter became ‘extinct’.
To give a prop to his thesis, he referred to certain skeletal remains found at Mohenjo-daro, which, he held, provided evidence of a ‘massacre’ by the invaders.
