Litvish, to answer your question, no, 1500 years is not enough time for physical features the change “naturally” as a result of climate or other environment factors it’s not even close. The reason ashkenazim have European features is certainly due to intermarriage. However, I don’t think you have to be “very disappointed” as a) intermarriage from a genetic perspective can actually be geirei tzedek b) it would take a very small amount (~1%) over the course of many years to produce the phenotypical changes we observe in ashkenazim.

The those denying that ashkenaz Jews are of Middle Eastern decent(slonimer), what?! Not only is it scientifically irrefutable it’s also Torah l’moshe misinai – read sefer beraishis. Our closest genetic relatives are the Lebanese. The avos and for hamidbar etc most definitely looked Middle Eastern. Probably, ou have internalized Western values that white is better which is why it’s hard for you to admit.
