No idea about skull forms - from what I read they can change depending on childrens' diet, growing speed and whatnot.
But since you mentioned Neanderthals, I'm convinced Europeans' pale skin is their legacy. People in other places in the north or south were not nearly as pale. For Greenlanders or the indigenous people of Fireland or New Zealand one can make the case they haven't been living there as long. But the people of Tasmania were there as long or even longer than anatomically modern humans have been in Europe, and they were pitch black. 50000 years don't seem to be long enough to "bleach out" for a population. So we Europeans probably inherited this adaptation to our lack of sunlight from the people who had been here for much longer time.
