Genetics and Skin Color
Unlike a suntan which is produced by external factors, different skin
colors are genetic. The type and amount of melanin produced by the
skin produces various skin colors ranging from “dark brown” to
whitish or pinkish skin tones.
Traditionally, the different variations in skin colors are also influenced
by geographical factors. Thus, people living in tropical and subtropical
regions who are exposed more to the sun's rays have darker skin,
while those living in middle latitudes or at the poles of the Earth have
lighter skin.
This classification used to be in accordance with reality several
centuries ago. Nowadays it is no longer valid, since there are many
people with dark skin living in temperate areas, while white people
can be seen in tropical and subtropical areas.
