You skin has a certain amount of the pigment melanin in it to protect it from the harmful UV light (in sunlight). If your family comes from an area where the sun is over head most of the time, you will make and have more melanin in the skin. If your people come from places where sunlight is less during the year (northern climates) you have less. It is all about a balance of getting enough vitamin D from sunlight as well. Lighter skin can absorb D if the pigment is less, while darker skin gets enough D but stopping damage to the skin is more important. Pigmentation is protective in these cases.
