The appearance of the skin is partly due to the reddish pigment in the blood of the superficial vessels. In the main, however, it is determined by melanin, a pigment manufactured by dendritic cells called melanocytes, found among the basal cells of the epidermis.
These results indicate that human skin color is darker in the Southern Hemisphere than in the Northern Hemisphere at equivalent latitude. Recent research shows that UV radiation is higher in the Southern Hemisphere than in the Northern Hemisphere at similar latitude.
Human skin color can range from almost black to nearly colorless (appearing pinkish white due to the blood in the skin) in different people.
Smooth muscle in all organs (stomach, intestines, bladder, uterus) is pale pink.
From about 1.2 million years ago to less than 100,000 years ago, archaic humans, including archaic Homo sapiens, were dark-skinned.
Darker areas of skin (or an area that tans more easily) occurs when you have more melanin or overactive melanocytes. Bronzing of the skin may sometimes be mistaken for a suntan. This skin discoloration often develops slowly, starting at the elbows, knuckles, and knees and spreading from there.
Dark-pigmented people living in high sunlight environments are at an advantage due to the high amounts of melanin produced in their skin. The dark pigmentation protects from DNA damage and absorbs the right amounts of UV radiation needed by the body, as well as protects against folate depletion.
It's no secret that Irish people are some of the palest – if not the palest – people in the world. When the hot weather hits, and temperatures soar, the Irish feel it the most on that pale skin from the land of the Celts.
Melanin is produced in melanocytes. These cells are located in different areas of your body, including: Your hair. The innermost layer of your skin.
In human beings, melanocytes, cells in the innermost layer of skin (the basal layer) and hair follicles, make melanin. This pigment gives color to your skin, hair, nose, inner ear, and choroid in the eyes (the area between the retina and the white sclera) (Schlessinger, 2021).
Light Skin Tones: Your skin is pale, and you burn and then tan. You might be pale in the winter and have a healthy glow in the summer. Medium Skin Tones: Your skin is of average tone, and you usually tan when in the sun.
Normal skin color varies from white to pink, and to yellow, brown, and black. In the different ethnic groups, there are pronounced variations in skin, head hair, and body hair.
Does Newborn Ear Color Determine Skin Color? Yes, babies do tend to turn the color of their ears. A baby's ears are colored due to melanocytes, which produce melanin. Melanin produces skin pigment and hair color in babies.
The preference for more golden or 'yellow-toned' skin as healthier might be explained by the 'carotenoid pigments' that we get from the fruit and vegetables in our diet. These plant pigments are powerful antioxidants that soak up dangerous compounds produced when the body combats disease.
They found the darkest skin in the Nilo-Saharan pastoralist populations of eastern Africa, such as the Mursi and Surma, and the lightest skin in the San of southern Africa, as well as many shades in between, as in the Agaw people of Ethiopia.
In Closing - The Takeaway. The most attractive skin tone is a healthy complexion i.e one that is not damaged by the sun, does not have unsightly acne lesions and is reasonably firm and wrinkle-free. These are the markers of youthfulness, vigour and good genes regardless of where you are in the world.
One reason: “The skin in the folds of our buttocks, armpits, elbows, and backs of our knees all have a higher concentration of melanocytes — the cells that produce melanin, which is responsible for our skin pigment,” says Dr. Kristina Semkova, a consultant dermatologist at the Cadogan Clinic.
Dark stomach skin can be due to hormonal imbalance, accumulation of dirt or dust on the skin or a chemical reaction. Sometimes, your lotion or cream may also react with the skin thus leading to a dark stomach.
A new genomic study has revealed that Aboriginal Australians are the oldest known civilization on Earth, with ancestries stretching back roughly 75,000 years.
Evidence still suggests that all modern humans are descended from an African population of Homo sapiens that spread out of Africa about 60,000 years ago but also shows that they interbred quite extensively with local archaic populations as they did so (Neanderthal and Denisovan genes are found in all living non-Africa ...
A new genetic study suggests all modern humans trace our ancestry to a single spot in southern Africa 200,000 years ago.
