“In India, we learned that in order to get the work published, we had to make a compromise. We had to let the Indian researchers write the paper in a way that puts a gloss on what the genetic data actually show.”

“The compromise was to describe the mixing of different groups in India as having occurred between ‘Ancestral North Indians’ and ‘Ancestral South Indians,’ a terminology that implies parity between the groups, rather than calling them what they really were: a mixture between West Eurasians (including Steppe migrants) and indigenous South Asians.”

“It was a politically motivated maneuver to avoid inflaming what is perhaps the most politically sensitive topic in India: the origin of the caste system.”
