This piece of ad hoc nonsense was coaxed into being (in large part, at least) by one Professor Mattias Jakobsson "a population geneticist at Uppsala University who co-authored the study."
It is a striking example of just how supine and flexible "science" is. Science will tell the tax slaves whatever the ruling elite wants them to hear.
So will Professor Jakobsson's next work will be about how genetically Ashkenazi Jews can demonstrate no connection whatever with the land of Palestine?
Somehow I think not.
However, one thing is for sure. Professor Jakobsson's funding for his next project is as good as in the bank.
