In other words, a complex variation in skin color has been part of human evolution for a very long time. Another finding is that at least some skin color genes have changed significantly over time.

Although all humans have the same number of melanocytes, the amount of melanin they produce differs and gives rise to the variation in human skin color. “To understand what causes different ...

Previous studies had revealed some genes behind melanocyte maturation and melanin production, but only enough to explain between 23% and 35% of the variation in human skin color, Wysocka and her ...

Their skin faded as they moved north, because lighter-skinned humans survived Vitamin D deficiency and lived to reproduce. It took many generations to result in the variation of our species.
