Another paper published in the same journal in 2006 by Sengupta et.al. after examining the Y-DNA R1, R2 haplogroups of 36 castes and 17 tribal populations in India with 8 in Pakistan, 175 in East Asia, had concluded that the influence of Central Asia on the genetic pool of the Indian population is insignificant. They have even claimed that the genetic complexity of the Indian populations had already been stabilized between 13000-8000 BCE and therefore, they said that there is no evidence of Aryan Migrations to have happened in the 2nd Millennium BCE.
