Actually
@Adam Hitler I think you might be overlooking some possibilities. #1 is that these hominids who came out of Africa might not have even been Black. Or Maybe they were less Black than today's Africans. Their migration may have coincided with the Ice Age when the earth was colder & Spain/North Africa were climatically more like Northern Europe. Much of N Europe was covered by glaciers making a large area uninhabitable. So these 'Africans' from that period might have been fairer skinned than today's Africans. Likewise an inhabitant of prehistoric Spain may have been fair skinned like today's English people. 'North' was much further South. Arctic wildlife roamed Southern Europe.
Plus I don't think they crossed directly from Africa into Europe. For one thing the glaciers might have been an obstacle which prevented this migration. So it's more likely they migrated into the Middle East and then into Europe. So a couple of generations later their racial composition might have changed from the initial migrants who entered from Africa.
Blue Eyes appear to be a genetic mutation which originated 25,000 years ago in the Middle East or nearby Central Asia. Before that blue eyed people didnt exust.
This according to scientists. So the stopover from Africa into the Middle East altered the genetic makeup of these prehistoric migrants.
Caucasian people originated from Central Asia and then gradually migrated into Europe
