On evolution, it only makes sense a creator WOULD allow a species to evolve.
Why is it that the whitest races/people originate from the nordic regions, with weak sunlight, months of darkness, cold where they are fully clothed, and the darkest color are those in a very hot, sunlight, and naked or close to naked.
When very white people are exposed to sunlight, they tan.
So skin color alone, as it is in modern times, is the result of civilizations for thousands of years living in those areas, and generation after generation.
Why are there no dark black people who had been in sweden for thousands of years or vice versa?
If one asks why then don't blacks who give birth in sweden create whites? Because the body and dna was altered over thousands(?) of years being in Africa. Airplanes and fast travel are only the past century.
