Why do the people of tropical regions have dark skin color while people living in temperate and polar regions have light skin color?
because they tan more, cause they can aford it.
What color was neanderthal skin or were the different by geography like us?
Studies suggest that Neanderthal skin color varied by geography, similar to modern humans. Genetic analysis indicates they likely had fair skin in regions with less sunlight and darker skin in regions with greater sun exposure. However, the exact skin color of Neanderthals is still debated among researchers.
How do animals live in desert regions?
Buy their skin and how it reacts to the hot desert
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.
Why do animals in the polar region have thick fur and skin?
The animals in the polar regions have thick fur and thick skin to protect themselves from the cold climatic conditions.
What regions of the body are affected by Refsum's disease?
Refsum's disease affects the nervous system, eyes, bones, and skin.
What is a pacinian corpuscle?
Used in detecting pressure in fingertips, palms, soles of the feet, and other hairless skin regions.
What are the four layers of skin?
Going from surface down, the epidermis is the outermost layer, then the dermis (including the papillary and reticular regions ) and then finally, the subcutaneous. :)
How did light skin people come about?
Light skin is believed to have evolved in populations living in regions with less intense sunlight to help absorb more sunlight for vitamin D production. As humans migrated to regions with less sunlight, there was evolutionary pressure for lighter skin to support vitamin D synthesis. Over time, genetic mutations leading to lighter skin tones became more prevalent in these populations.
What is the disorder on black men and women that turns their skin much darker than their regular skin?
Hyperpigmentation is a catch-all term for overproduction of melanin in the skin. There are a number of conditions that cause this symptom, and none of them are specific to African Americans. Vitiligo, is the opposite of this condition, when regions of skin are lacking melanin-producing cells. This is the condition that Michael Jackson had.
What factors influence colors?
Skin color has to do with the amount of melanin that a person produces, which generally corresponds to the climate that their ancestors originated from. Generally, peoples from regions closer to the equator have darker skin and those farther from it have lighter skin. Ultraviolet B radiation increases the production of melanin by melanocytes, so that both genetics and environment influence skin color.
Does living in a cold or hot country determine your skin color?
Skin color is primarily determined by genetics and evolution, not by the temperature of the country you live in. People with darker skin tones often live in hotter regions as they have more melanin, which protects against sun exposure. Conversely, those with lighter skin tones tend to live in colder regions where less melanin is needed for sun protection.
