Without vitamin D our body can't utilize calcium and out skeletons don't form properly. Just think, if Flintstone vitamins had been around we'd all be black. I love sharing that fact with racists assholes.

High melanin levels were necessary to protect folate which is damaged by UV radiation.

Those of us who are "melanin-deficient" are that way because our northern ancestors didn't need as much melanin to protect their skin from the sun, which there wasn't much of where they lived. We are probably a minority globally because not as many people have ever lived in those cold, dark regions. Those who have more melanin have it because their ancestors needed it. That's evolution for you. Genetic variations all over the place. We can only hope that someday those variations will be accepted for what they are.

All three of the claims listed above appear in disputes over the significance of human population variation and “race.” In particular, the American Anthropological Association (1997, p. 1) stated that “data also show that any two individuals within a particular population are as different genetically as any two people selected from any two populations in the world” (subsequently amended to “about as different”). Similarly, educational material distributed by the Human Genome Project (2001, p. 812) states that “two random individuals from any one group are almost as different [genetically] as any two random individuals from the entire world.” Previously, one might have judged these statements to be essentially correct for single-locus characters, but not for multilocus ones. However, the finding of Bamshad et al. (2004) suggests that an empirical investigation of these claims is warranted.

Races within a species denoted fuzzy boundary differences among phenotypes. Race was an even more indistinct category than subspecies.

God damn racists!
