White skin and blue eyes origin.

I believe that white skin, blue eyes and blonde hair originated in Africa from dark skinned people interbreeding with albino people. I think the albino was regarded as a prize, maybe as a king queen or leader of a group. Their migration was mainly north to Scandinavia, staying together as a closed society with no more interbreeding with any dark skin people.
Iv'e read that scientists say white skin blue eyed people are a product of living in northern cold climates with very little sunlight causing less melatonin in the skin. If that's the case, what about Eskimos or Mongolian race? Why don't they have blonde hair and blue eyes?

Thanks for a reply. I don't have any sources for my assertion. I just think it makes sense and hoped to get some feed back. I've always been interested in the "WHY" of everything. That's all I can tell you.
