We can agree to disagree here. I think ancient DNA would establish with confidence if Indo aryan came to India after IVC collapsed or were already well established in India during mature harrapa time. Everybody would have to adjust the theories accordingly irrespective of tribal pride or biases.shiv wrote: Not at all.
You are speaking only from the viewpoint of genetics, but when a genetics paper cites a reference which is in turn based on a nonsense archaeo-linguistic document it counts as a "cite". Sooner or later this genetics paper will be used as a cite in an archaeological or linguistics paper and then we have a gradual ecosystem of ever increasing "cites" of nonsense about language spread.
Unfortunately genetics can never ever prove language spread, but genetics papers that show migration of people from point A to point B are used to "prove" nonsensical hypotheses about language spread. The rigor of proof that geneticists and other scientists require for their work simply does not exist for linguists and archaeologists, but they often pass off nonsense as science. So it is important to call out and critique every single genetics paper (or any other paper) that cites nonsense references so people know and a red flag goes up the minute that reference is cited
But let's not doubt genetic findings. They are coming our way...ready or not.
