the best way to understand the Indian population is to imagine it as a pizza, with the first Indians forming its base. Though the base of this rather irregular pizza is thin in some places and thick in others, it still serves as the support that the rest of the pizza is built upon because studies show that 50% to 65% of the genetic ancestry of Indians derives from the First Indians.
On top of the base comes the sauce that is spread over the pizza – the Harappans. And then come the toppings and the cheese – the Austro-Asiatic, Tibeto-Burman and Indo-European language speakers or Aryans, all of whom found their way into the subcontinent later.
To many in the Hindu right wing, these findings are unpalatable. They have been campaigning to change school curricula and remove any mention of Aryan immigration from textbooks. And on Twitter, several hugely popular right-wing “history“ handles have long been attacking India’s leading historians who have defended the theory of Aryan migrations and continue to do so.
