pigment

What:

"People who have more melanin are more protected from the sun's harsh rays, because the pigment is like a sunscreen. This is good because UV rays can take away important folic acid that's needed for a healthy body. This adaptation in skin color was evolution's way of protecting our ancestors from the sun, and then they passed their skin color on to us."
