Globally, we're a minority. A genetic variation. That is all.

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

(115,609 posts)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.

(32,641 posts)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.

God damn racists!
