If being white is an "anomaly"... well, let's just say that would explain a hell of a lot for this white guy
If only they had known what scientists have since discovered - white skin is actually an anomaly!
Being white isn't an anomoly, per se, it's an evolutionary response (genetic reaction) to sunlight. Your skin color is a result of a genetic variant that controls how much eumelanin that your skin produces. Eumelanin helps to protect your skin (your body's largest organ, BTW) from ultraviolet light from the sun. However, that genetic variant also influences something else.....your ability create vitamin D from the sunlight.
High eumelanin production blocks you from producing vitamin D from the sunlight. The tone and color of a peoples skin is almost, like, 99.999% related to how much direct sunlight the area you live in receives. The farther north or south you move away from the equater the lighter the skin becomes (historically speaking). That mutated response to allow peoples who get LESS direct sunlight to more efficiently use all of that available light to produce vitamin D. The phenotype, that is, the outward expression of that mutation, becomes more and more apparent as you move farther north or south away from the equator. People get whiter and whiter. Red hair is also an expression of that mutation.
So, how do our darker skinned peeps get vitamin D? They have ANOTHER genetic variant that allows them to synthesize vitamin D from cholesterol. A noteable exception to this are the Inuit (Eskimos). They get vitamin D from their diet, so they never needed to get lighter skin.
