The Aryan theory dies, again

Recent genetic studies have placed the age of the separate north Indian and south Indian communities at roughly 12,500 years. That's a whole lot older than the 1500 BC date assigned to the arrival of the imaginary Aryans till now by various eminent scholars (politically motivated, or otherwise).
Though the theory changed, two factors remained constant: the existence of two separate groups (Dravidians and Aryans) and their identification as natives and foreigners. The scholarly consensus is that the Indo-Aryan speakers arrived in North-East India following the decline of the Harappan civilisation. These horse riding migrants introduced Vedic religion and Sanskrit language and culturally transformed a region bigger than ancient Mesopotamia and Egypt combined, non-violently.

Now a new paper published in the American Journal of Human Genetics states that current Indian population is derived from two ancestral populations—the Ancestral North Indians (ANI) and Ancestral South Indians (ASI)—both of which are older than 3500 Years Before Present (YBP). Though this seems to confirm the Aryan-Dravidian divide and the migration which happened after 1900 BCE, the paper actually does the opposite; it refutes the large scale migration version of the Aryan theory.
