Interesting map!
I believe that the Mediterranean admixture in most folks in Asia & Africa is
not from Europe!
If it was from Europe, 'Northwest European admixture' was there in very high ammounts too!
I believe that the Mediterranean admixture in Asia is Semitic/Jewish and native to the Levant, since it's very high among the native people of the Levant, but Northwest-European-admixture is almost abscent there! So it's
not from Europe!
I mean these 2 maps don't correlate with each other outside Europe!
