Why do people with dark skin color have low fitness far from the equator?
People with darker skin have melanin, which provides protection from the sun's ultraviolet (UV) radiation. In regions far from the equator, where UV radiation is lower, having more melanin is less advantageous. As a result, the evolutionary pressure for maintaining high levels of melanin decreases, leading to a decrease in fitness for individuals with dark skin in those regions.
Is the skin reflectance randomly distributed throughout the globe?
No, skin reflectance is not randomly distributed throughout the globe. It is influenced by factors such as evolutionary adaptation to the local environment, sunlight exposure, and genetic variations. As a result, there are noticeable patterns of skin reflectance that correspond to geographical regions and populations.
Why do some people have dark skin?
People have dark skin due to higher levels of melanin, a pigment that gives skin its color. Melanin helps protect the skin from harmful UV radiation by absorbing and dissipating it. Darker skin is an evolutionary adaptation for people living in regions with intense sunlight to reduce the risk of skin damage and skin cancer.
Do Black people have sweat glands?
Yes. In fact they have the most of any race. Since dark skin converts harmful UV radiation to heat, peoples with dark skin have adapted by developing more sweat glands.
Why do different races have different skin tones?
Skin color is determined by the amount/intensity of the sunlight affecting people where they lived over a long period. Dark skin is best in places where the sun is strong (the tropics) as it prevents the sunlight damaging the skin. Light skin is best in places where the sun is weak (the temperate regions) because sunlight needs to penetrate the skin to make vitamin "D" and dark skin prevents this penetration when the sun is weak. Therefore people with dark skin need to make sure that their diet contains extra vitamin D when living in temperate regions and light skinned people need to use sunscreen and cover up on tropical regions so that they do not burn.

Where did black people originated from?
All people on Earth are related; we share 99.99% of the same DNA. Skin colorations evolved according to where people settled and remained. Those in colder climates with less sunlight became lighter in skin color. Those who lived in hotter areas with more intense sunlight evolved to have darker skin.
