I do agree too with the general principle that the pattern of R1b in Asia among various groups is telling us something about its former position or chronology of its spread. I have never given up the possibility that R1b was simply an early particularly western steppe group that (like so many steppe groups) moved or was pushed out south and west. L23's distribution can be made sense of it it was pushed out in two directions from the Ukraine steppes area (south through the Caucasus to Iran and SW Asia and west into the Balkans and later Anatolia/Armenia. It cannot be ruled out and the modern population largely only occupied the old Ukraine steppes lands of the Tatar Khanate 3 centuries ago.
