Well, I don't see any real evidence that environment is a factor. But you are right on with genetics. As far as skin color in certain regions, I just see it as according to migration patterns for the best hospitable environment depending on genetic makeup. Of course in the age of AC and central heating, this varies more now.

When I say sunlight exposure is the only real factor in skin tone, I mean from a genetic selection point of view. If you stick a group of people in Iraq and have them breed for dozens of generations, you'll end up with darker skinned folks. I wasn't suggesting it was only an environmental influence for a single generation.
