.Our skin Composition
Dark skin is a naturally occurring human skin color that is rich in melamine pigments and having a dark color. People with relatively dark skin are referred to as brown, and those with very dark skin are often referred to as black, although this usage can be ambiguous in some countries where it is also used to specifically refer to different ethnic groups or populations.
The evolution of dark skin pigmentation is believed to have begun around 1.2 million years ago, in light skinned early hominid specifies after they moved from the equatorial rain forest to the sunny savannas. In the heat of the savannas, better cooling mechanisms were required, which were achieved through the loss of body hair and development of more efficient perspiration The loss of body hair led to the development of dark skin pigmentation, which acted as a mechanism of natural selection against folate depletion, and to a lesser extent DNA damage. The primary factor contributing to the evolution of dark skin pigmentation was the breakdown of folate in reaction to ultra violet radiation the relationship between folate breakdown induced by ultraviolet radiation and reduced fitness as a failure of normal embryologists and spermatogenisis led to the selection of dark skin pigmentation. By the time modern Homo sapiens evolved, all humans were dark-skinned.
Humans with dark skin pigmentation have skin naturally rich in melamin (especially Eumelamin), and have more melanomas which provide a superior protection against the deleterious effects of ultraviolet radiation. This helps the body to retain its folate reserves and protects against damage to the DNA.
These populations almost exclusively live near the equator, in tropical areas with intense sunlight: Australia, Melanesia, New Guinea, South Asia and Africa. Studies into these populations indicates that dark skin is a retention of the pre-existing high UV adapted state of modern humans before the out of Africa migration and not a later evolutionary adaptation.Due to mass migration and increased mobility of people between geographical regions in the recent past, dark-skinned populations today are found all over the world.

Do you know that your skin colour is darker for very good evolutionary and biological reasons and that medically speaking, it is good that you do not have very fair skin?
Darker skin is adapted to sunlight and has increased quantity of a pigment called melanin. The more melanin you have, the darker your skin.And the safer you are! Melanin along with other factors, acts as a “natural umbrella” and prevents harmful radiation from entering your skin. These are just some of the reasons why black skin is safe and beautiful:
You are less prone to sunburns:White skinned individuals often get painful, carrot-red or tomato-red inflamed sunburns on exposure to sunlight. Some individuals also get blistering sunburns requiring aggressive medical treatment to control the reaction. Your darker skin allows you to spend a much longer time on the beach and you probably have never ever experienced any blister due to sunlight.
You do not experience photoaging: Fine and deep wrinkles, broken blood vessels on the nose and cheeks, freckles, age spots and rough scaly spots called keratosis are commonly seen in white skinned individuals with long term sun exposure. These set of changes are called photo-aging. Because of natural sun protection, your black skin remains has less wrinkles and is smoother, even when exposed to the same amount of sunlight.
You are less prone to skin cancers:Without melanin, you can imagine white skin as a transparent covering, which allows harmful UV light to penetrate through into the lower layers of the skin. This radiation causes damage to the DNA and a few cells may mutate to cause skin cancers, some of which are deadly. You are lucky that your “natural umbrella”blocks UV light effectively and cells in different layers of the skin suffer much less damage compared to white-skinned individuals. However, don’t forget to see a dermatologist in case you see any new bump, or in case you see any change in (a)symmetry, border, color, diameter or evolution (ABCDE) of any existing mole on your skin.
. Be proud and be happy that you have dark skin.
. Our skin disadvantage
To be honest with you I don’t know any disavantage about the black skin except that Dark-skinned people who live in high latitudes with mild sunlight are at an increased risk – especially in the winter – of vitamins d defiscient. As a consequence of vitamin D deficiency, they are at a higher risk of developing rickets , and numerous types of cancers, and possibly cardiovascular disease and low immune system activity.However, some recent studies have questioned if the thresholds indicating Vitamin D deficiency in light-skinned individuals are relevant for dark-skinned individuals, as they found that on average dark-skinned individuals have higher bone density and lower risk of fractures than lighter-skinned individuals with the same levels of Vitamin D. This is attributed as possibly due to lower presence of Vitamin D binding agents (and thus higher bioavailability) in dark-skinned individuals.
. Taking care of the dark-skin
