However, people who lived  closer to the poles, where solar rays are weaker and more diffuse, lower concentrations of melanin allowed people to collect vitamin D.

If you are vitamin D deficient then you can contract diseases associated with bone pain and muscle weakness.

People with lighter skin require more vitamin D because they have less melanin. People with lighter skin have more of a chance of getting vitamin D deficiency.
