The distinct categories in the chart above did not predominantly come about through mixture with different population groups - but through reproductive isolation within their own group.
Iranians are a distinct population group. Distinct enough to have their own name for thousands of years for that population group “Persian”.
If you want to use an archaic system based upon the simplistic thinking that there are and can only be five categories - and the idiocy of thinking any distinction among those five categories is through ‘mongrelization’ - you can go ahead.
But let us not pretend it is either accurate or scientific or based upon any actual data.
We’re not discussing distinct population groups; we’re discussing the major, scientifically-accepted, anthropological racial classifications, which is what I posted, based upon that source.
Until you post something more modern and widely-accepted by the scientific community and world to document your faux chart, the rest of the world is still using those categories. You can say what you want; that doesn’t make it fact. Try again.
Again, what’s your source for that “idiotic chart”?
