According to the video “The Biology of Skin Color”, why is it that the allele coding for darker skin did not evolve to protect us from skin cancer?
A. Because skin cancer isn't harmful
B. Darker skin did develop to protect us from skin cancer
C. Because skin cancer usually develops after an individual's reproductive years, so it doesn't affect the ability for someone to pass on their genes
D. Because skin cancer usually develops before an individual's reproductive years, so it doesn't affect the ability for someone to pass on their genes
