The graph in Figure 2 summarizes the age at which people are diagnosed with melanoma, the most serious form of skin cancer. Why does protection from skin cancer not explain the strong selective pressure for dark skin in high UV ares.
Because the median age is 63.
Because most people get skin cancer at a young age.
Because most people get skin color at an old age.
Because many people get skin color at an older age after they have already had children and probably passed the gene onto them.
