Unscramble the Blue Letters

What's significant to the story of human skin pigmentation is just how much of the Northern Hemisphere is in these cool gray zones. This has tremendous implications for our understanding of the evolution of human skin pigmentation. And what Darwin could not appreciate, or didn't perhaps want to appreciate at the time, is that there was a ulnfedntama relationship between the intensity of ultraviolet aitaidnor and skin pigmentation. And that sikn pigmentation itself was a product of evolution. And so when we look at a map of skin orcol, and predicted skin color, as we know it today, what we see is a bieuuflta gradient from the sdrkeat skin aegimntsnopit toward the equator, and the lightest ones toward the poles.

What's significant to the story of human skin pigmentation is just how much of the Northern Hemisphere is in these cool gray zones. This has tremendous implications for our understanding of the evolution of human skin pigmentation. And what Darwin could not appreciate, or didn't perhaps want to appreciate at the time, is that there was a fundamental relationship between the intensity of ultraviolet radiation and skin pigmentation. And that skin pigmentation itself was a product of evolution. And so when we look at a map of skin color, and predicted skin color, as we know it today, what we see is a beautiful gradient from the darkest skin pigmentations toward the equator, and the lightest ones toward the poles.
