Discover the secrets of Africans
Not only the rich chocolate color of the skin of African people, but also their anatomical features sometimes surprise and cause a lot of questions.
Why do Africans have dark skin?
There is a lot of eumelanin in their body – it is responsible for pigmentation. Scientists from the UK wondered why the pigment came from just this nation and found that evolution was to blame. Due to pigmentation, the amount of skin cancer due to excess ultraviolet radiation has decreased. These findings are made by observing people with albinism in Africa. It turned out that more than 80% of them develop cancer before the age of 30 years.
In other words, the appearance of dark-skinned people was the result of natural selection. Due to the fact that the white-skinned people in Africa died out before conceiving their offspring, and mutations occurred.
Why do Africans have white teeth?
The snow-white smile of the inhabitants of African tribes is the result of their food. In their diet – more natural products that are rich in fat-soluble vitamins. Also in Africa do not abuse sugar and dishes with its high content, however, as well as hamburgers, convenience foods, drinks, destroying and coloring enamel. Interestingly, our ancestors followed the same diet. And if we had kept their eating habits, we would also have beautiful white teeth now.
In addition, Africans constantly chew the twigs with which they clean and bleach the enamel. Residents can walk with them in their mouth all day.
At the same time, we should not forget that the teeth of Africans can look white against the background of their dark skin. And in the pictures, the effect of the whiteness of enamel is enhanced by flashes and special equipment of photographers.
Why do Africans have big lips?
It is very hot in Africa and it is important for the body of local people to be able to protect themselves from overheating. He does this by evaporation of moisture. It is carried out in two ways – through sweating and through breathing.
To evaporation was more intense, nature took care of a large area of skin and mucous membrane. That is why Africans have long arms and legs, wide nostrils, full lips (these are just slimy). The degree of completeness may vary depending on gender, age, structure of the skull (there are people who have the upper jaw protruding).
Why do Africans have red or yellow whites of their eyes?
In some dark-skinned people you can actually see yellow sclera, or whites of the eyes. This is due to the high concentration of melanin pigment, which stains not only their skin, but also the mucous membrane.
Blistering sclera can with exhaustion, increased dry air, especially if there is also a lot of dust. In addition, Africa cooks food on a fire, and acrid smoke also irritates the eyes.
Why do Africans have a big belly?
The large, swollen stomachs of Africans in the photographs are the result of protein starvation. The condition is called kwashiorkor – this is one of the types of dystrophy, which is accompanied by ascites, bloating. Symptom says that the selected diet is not suitable for a person. But in Africa there is an acute shortage of food, and it is difficult to change the situation.
Why do Africans have big penises?
It is believed that the inhabitants of Africa – the largest reproductive organs. This refers to men from Ghana, Nigeria, the Democratic Republic of the Congo, etc. The average length of the penis in the erect state is 16–17.78 cm, while the average penis of a man on the planet is 13–15 cm. opinions that this is due to genetics, cultural characteristics.
One of the versions – the “king-size” of the father is inherited. And it was not difficult to choose a father to a child in Africa before a woman – male bodies always remained naked. It is believed that men with small penises were not particularly attractive, and did not leave numerous offspring.
