Indigenous groups have different skin colors for a few main reasons:
-
Sunlight: The amount of sunlight in a region affects skin color. In areas with lots of sun, like Africa or South America, people typically have darker skin. Darker skin protects against the sun’s harmful rays. In places with less sunlight, like Europe or parts of North America, people often have lighter skin. Lighter skin helps absorb sunlight, which is important for making vitamin D.
-
Environment: The environment where people live plays a role too. For example, some areas have more clouds or rain, which can lead to lighter skin over time.
-
Genetics: Skin color is also inherited from our parents. Different groups have different traits that are passed down through generations, influencing skin color.
-
Adaptation: Over many years, people adapt to their surroundings, including changes in skin color to better suit their environment.
So, in summary, skin color differences among indigenous groups come from how much sun they get, where they live, family genes, and how people adapt over time.
