¿Por qué somos diferentes? Tú color de piel

The video explores how evolution has led to variations in skin color, primarily due to melanin, which provides sun protection. Darker skin is more common near the equator, while lighter skin is found near the poles. Melanin also prevents vitamin B9 degradation, while lighter skin aids in vitamin D production. Adaptation to different environments is discussed, noting that recent migrations may not have allowed enough time for full adaptation. Modern solutions like sunscreen and vitamin D supplements are also mentioned.
