Look for an article entitled the aryan Dravidian controversy by David Frawley.
Very interesting article:
http://www.indoaryans.org/Aryan-Dravidian-Controversy.html
Though, it seems European in scholarship. You know the old phrase--"How can you tell if a White person is lying? Answer: If his mouth is moving."
One thing about this text, is that it claims that the Indus Valley Civilization is a "Vedic" (North Indian) civilization. Robbing the Dravidians of their ancient civilization, but further destroying the idea that originally Nilotic people developed Southern India.
More, it goes on that bull crap that the Dravidians are a Caucasian people. This belief would make the ancient Buddha, a subject related to this thread, a Caucasian person despite his heavily Negro features: thick lips and such.
Finally, this article is contrary to observations:
Mr. [Wilford] . . . informs us that many very ancient statues of the God Buddha in India have crisp, curly hair, with flat noses and thick lips; and adds, “nor can it be reasonably doubted, that a race of Negroes formerly had power and pre-eminence in India.” This is confirmed by Mr. Maurice, who says, “The figures in the Hindoo [sic] caverns are of a very different character from the present race of Hindoos: their countenances are broad and full, the nose flat, and the lips, particularly the under lip, remarkably thick . . .” [The] testimony of the Rev. Mr. Maurice is fully confirmed by Sir W. Jones, who says, “The remains of architecture and sculpture in India . . . seem to prove an early connexion between this country and Africa . . . the ancient Hindus, according to Strabo, differed in nothing from the Africans but in the straightness and smoothness of their hair, while that of the others were crisp and woolly; a difference proceeding chiefly, if not entirely, from the respective humidity or dryness of their atmospheres.
