Skin color is evidence of evolution. It filters the sunlight to affect vitamin D concentrations, especially important in pregnant women for infant mortality.

Going from highest sunlight environment to lowest, Africa to Scandanavia you go from darkest skin to lightest in a gradient.

Allele frequency change in populations over time=EVOLUTION.

I agree that micro-evolution is one paradigm that fits the observed conditions. Is it the only possible one?

I will grant you that it seems an adequate answer, and inasmuch as I'm qualified to judge such things, it's probably correct. However, I should observe that regional variation in melanin content in human skin is a far cry from speciation. Making the leap from micro-evolution to macro-evolution isn't supported by observation.

That doesn't mean it's wrong, mind you; it just means that it isn't proven.

There is only evolution. Micro and macro are scientific techincal uses you would not understand. Scam artists at AIG and ICR have twisted the definition of micro and macro to deceive you into thinking they are different processes.
