Maybe, but my point is that it initially appeared in the middle east (and probably in northern Eurasia at a similar time) but was likely first introduced throughout most of Europe by migrants/invaders from modern day Turkey. The people who lived in Western Europe for likely longer that it took for white skin to evolve in the middle east/caucasus(?) region were much darker skinned. Also given how long anatomically modern humans have existed several thousands years is not such a short period.
