Yeah, no disrespect to the Kalash. I'm meaning that when the model splits them you're starting to get outgroups that don't tell you much of use. K=10 would have had several Pacific islands as outgroups and a single Basque man whos family have not come down from the Pyrenees in 7 generations. You'd have to increase your number of DNA samples and loci to begin revealing things of interest to anthropologists. Probably by a lot.The Kalash are argued to be distinct from the general population of Afganistan, and at least the Kalash themselves claim that (their tradition is that) they are descended from Alexander the Great's soldiers/other groups brought during that expedition.
At any rate there were greek kingdoms in central Asia (up to India) even after the rest of the greek world was conquered by Rome or Parthians.
