The color of the human skin is due to a brown pigment called melanin. Pigmentation or coloration of the skin is dependent on the amount of melanin present in the skin. People with pale skin produce very little melanin and people with darker skin produce higher amounts of melanin. Pregnancy and sun exposure can also make skin darker, while infections, burns, and blisters can make skin lighter.
Who are we? Where did we come from? How did we get here? Throughout the ages, humans have sought answers to these questions, pursuing wisdom through religion, philosophy, and eventually science.
