Melanin is the pigment which helps our skin to be defensive against over exposure. Normally when you are exposed to sun light the skin will produce melanin automatically. But people from cold climates won't need melanin as the sun light is not strong over there. So people from colder area tend to be white. But people from hotter climates need melanin to prevent sun burn so their body is programmed to do so. More melanin means the darker the skin. The reason why melanin turns our skin to black is, black color can absorb the light, but white will reflect the light. If the light is being reflected only the skin will be exposed to heat and that will damage the skin which is sunburn. But dark skin will absorb the heat and transfer the heat to the inner body parts under the skin and thus by having less damage on the skin.

Most responsible for the skin color of dark skinned people?
melanin
Does dark skin have more melanin compared to lighter skin tones?
Yes, dark skin has more melanin compared to lighter skin tones. Melanin is a pigment that gives skin its color, and higher levels of melanin result in darker skin tones.
How did black people get dark skin?
from melanin. this is what the creator wanted so get over it.
What is dark pigment of the body called?
The dark pigment of the body is called melanin. Melanin is responsible for determining the color of our skin, hair, and eyes. It helps protect the skin from the damaging effects of the sun's UV radiation.
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.
Is hemoglobin mostly responsible for the skin color of Caucasians?
Yes it is! And Melanin is responsible for the skin of dark-skinned people.
Why does skin get dark in the sun but not hair?
Our skin contains melanin. Melanin is a chemical that gets darker due to UV rays. Our hair on the other hand, contains no melanin.
What is a Dark-Colored pigment present in skin cells?
Melanin
Dark-colored pigment present in skin cells is what?
Melanin
What makes you black?
My skin has a lot of melanin. Melanin is responsible for darker skin colors. Whiter people have less melanin than darker people.
State the specific location of melanin observed in dark skin?
Melanin in dark skin is primarily located in the basal layer of the epidermis, where it is synthesized by melanocytes and transferred to surrounding keratinocytes. This results in a higher concentration of melanin in the skin, providing protection against UV radiation and giving dark skin its characteristic color.
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.
