Linguistics and archeology are what we have had up until the last 10 years or so, and language does not equal genetics. As is usual in academic circles there are theories and politics and the Out of India theory of Aryan origins was politically correct. It just wasn’t supported by the ancient DNA evidence which has recently come to light. Frankly it wasn’t well supported by the earlier evidence either, but somebody in academia needed a job, and promoting a line of BS worked to get them paid. Suggest you read By Steppe, Desert and Ocean by Barry Cunliffe if you get interested in a good recap of ancient Eurasian archeology and early history.
Those (and their number is legion) who cannot resist injecting politics and political correctness into EVERYTHING, don't realize that they are as foolish as the Nazis who made up all that racist baloney.
I don't care what the truth is; we can deal with it honestly and benevolently, but distortions of truth only get in the way.
The massive DNA sampling/testing that is coming for India, Europe, the UK, America and the rest of the world is a time bomb for the PCers and the diversity worshipers.
The lefties know that, and that is why they are pushing their white privilege BS. They are the new flat world idiots, pushing bs instead of reality.

Mar 13, 2018 - Someone’s DNA could be used to predict their IQ for the first time, according to a new study. The research was the largest investigation into the link between intelligence and genetics ever, and was carried out by a collaboration of researchers at the University of Edinburgh, UK and Harvard University, USA.
