As there is a sun



The color is tan human skin gives a coloring substance melanin, produced by the body as protection against ultraviolet radiation. Melanin is formed each person, except maybe albinos. But much depends on belong to the human race. Fair-skinned people melaminovye cells are quite small and have low density. The increase in both parameters makes the skin darker. We can say that Africans melanin is produced in 2 times more than for example Scandinavians.

Dark skin also tans



However, the assertion that black people are better protected from harmful solar radiation and thus absolutely no risk of skin cancer, is fundamentally wrong. Purely visually, the difference between tanned and untanned blacks may not be so noticeable. Moreover, only a small part of the population of African descent can boast a completely black skin color. In the bulk of the color type they varies from dark brown to shade "coffee with milk". And if the European and the African will hold the same amount of time under the sun, the first time to very severe burns while the second will only be a semitone darker. That is get a tan.

Dangerous sunburn


However, for black people the sun can be even more dangerous than their light-skinned counterparts. On the one hand, they too have light skin, able to burn without protection. First of all we are talking about feet and hands. Secondly, it is the dark skin color gives you time to recognize a sudden melanoma. If the white man saw this education, immediately go to the doctor, a dark-skinned miss precious time simply because they don't even know is seriously ill, and continues to be exposed to deadly radiation.

Negros are 10 times less likely to develop cancer of the skin, but the percentage of deaths among representatives of this race are disproportionately large.


Dark skin can also burn



Therefore, we can say that blacks not only sunbathing, but quite a able to burn or even cancer of the skin. That is, dark skin is not an absolute protection from harmful effects of sun rays.

Advice 2: How did the human race

Race - a community population of people with systematics geographic and hereditary basis. For each race a distinctive appearance distinctive features. The emergence of human races is not fully understood. The scholars differed.
Race - a community population of people
The question of the origin of human races, their original number and the entity are not fully understood. The process of the formation of races is referred to as reagent. There are two main theories recoginize having a scientific rationale. One theory championed by polycentricity, and the second - monocentricity.

The theory of policentrismo



Polycentricity of the opinion that the origin of the human races depends only on their ancestors at the genetic level. In the process of formation they are not depended from each other and originated from different ancestors from different places from the point of view of the geographical location. In other words, on different continents have evolved parallel to Homo sapiens.

Thus, on the territory of modern Europe gradually formed Caucasian ethnicity, Asia - Mongoloid, Australia - the controversial Australoid, and in Africa - Negroid. Some scientists do not recognize the Australoid race as a separate large, connecting it with the Negroid in the Australian and Negroid.

The weakness of this theory is that the production of pure race, from this point of view, is seen only in theory. In practice, there was a border territory, where members of different races interbred, creating the so-called small races. For example, Ethiopian small race is the result of combining representatives of the Negroid and Caucasoid races. Between Caucasoid and Mongoloid are two small race - Ural and South Siberian.

The theory of monozentrischen



Scientists who call themselves monocentricity, consider that the emergence of the human races was originally the result of common descent, and then separation by skin color and other external factors. They substantiate their theory is much more recent divergence of humankind into races than its origin.

On the theory of policentrismo, monocentricity has much more evidence, of which the first is the acquisition of the main features of Homo sapiens over many centuries before the divergence into races. The evidence can be attributed to the denial of full genetic isolation, so as to consider it impossible crossing in the border areas, as well as of the conquerors with the vanquished, is utopian. There is a third proof, not least, it is common to all races the downward trend in the total mass of the skeleton and of fast development.

Thanks to modern science, appeared a new proof of the theory of monocentrism based on data from the DNA study of the various races. Nevertheless, debate between supporters of the two hypotheses did not subside until now. Scientists in every scientific faction present their evidence of the origin of human races.
