If you want to trace why the color of human skin from different countries can be different, all roots from millions of years ago. Everything relates to how early humans survived in the middle of temperature to exposure to sunlight. Until now, geographical factors have also determined how the color of certain ethnic skin.
Pigmentation that causes a person to have a light or dark skin tone is equally beneficial. For example, people with dark skin color are better able to survive in places with abundant sunlight. On the other hand, those with light skin tones benefit from living in a place where the sun is not too hot.
Another interesting fact is that human skin color also affects a person’s risk level for melanoma cancer. The Fitzpatrick scale can predict how much a person’s risk of developing melanoma cancer is based on the color of their skin. This scale categorizes skin color based on the pigment content in the skin and how it reacts when exposed to the sun.
Skin color is one of the most striking differences in human beings all over the world. Many factors play a role, such as geographic location, exposure to ultraviolet light, genetics, and even culture.
Until now, research on differences in human skin color is still being carried out. In addition to what has been different since millions of years ago, in the future there is still the possibility of something else that reveals why the color of human skin around the world can be. Here are some examples of answers to science worksheets and the evolution of skin color.
