Исчезновение рыжего гена
Рыжеволосые люди всегда притягивали внимание к себе необычным цветом шевелюры. Ученые считают, этот цвет волос появился из-за пасмурной погоды в Северной Европе.
Животные с рыжей шерстью или птицы с перьями такого же цвета в природе встречаются довольно часто, но шатены в человеческом обществе появились только несколько тысячелетий назад. Это произошло из-за генетической мутации – в шестнадцатой хромосоме начали работать два рецессивных гена.
Ученые пришли к выводу о том, что организм человека старался обеспечить себя витамином «D», который необходим для формирования костных тканей и поддержания нормального обмена веществ. Для синтеза этого витамина нужно длительное воздействие солнечного света, а небо Европы, особенно северная ее часть, постоянно затянуто облаками, и количество солнечных дней было минимальным. Поэтому, кожные покровы человека стали более светлыми и приобрели способность больше поглощать ультрафиолетовых лучей. Одновременно с цветом кожи начал меняться и цвет волос. В итоге в организме северных жителей Европы содержание пигмента меланин, отвечающего за цвет кожи, уменьшилось, и его заменил феомеланан.
Меланин имеет очень важное значение в организме, так как он является мощным антиоксидантом и защищает человека от вредного воздействия радиации. Поэтому рыжие люди более восприимчивы к воздействию токсинов.
Сегодня во всем мире только двое из сотни человек имеют волосы рыжего цвета с момента рождения. Однако в Северной Европе из-за недостатка солнечного света их намного больше. Шатенов в Шотландии - 13%, в Ирландии – 10% и в Англии – 6%. Тем не менее, рецессивный ген часто проявляется через несколько поколений, и его могут иметь около 40% населения.
По мнению некоторых ученых рыжий цвет волос у человека исчезнет с нашей планеты примерно к 2060 году. Потому что в результате многочисленных смешанных браков, количество носителей рецессивного гена уменьшается. Но это не точный прогноз и вполне может быть, что рыжие люди будут еще долго рождаться в северной части Европы.

The disappearance of the Red geneRedheads always attracted attention to itself an unusual color sheveljury. Scientists believe this hair color appeared due to the cloudy weather in Northern Europe.Animals with red hair or a bird with feathers of the same color in nature occur quite frequently, but shateny in human society have appeared only a few millennia ago. This was due to a genetic mutation-in the sixteenth chromosome began working two recessive gene.Scientists have concluded that human body tried to provide themselves with vitamin D, which is essential for bone formation and maintenance of normal metabolism. For the synthesis of the vitamin you need prolonged exposure to sunlight and Sky Europe, especially the northern part, constantly covered with clouds, and the number of sunny days was minimal. Therefore, human skin lighter and more have acquired the ability to absorb ultraviolet rays. Simultaneously with the skin color and hair color began to change. As a result, in the body of the Northern Europeans pigment content of melanin, which is responsible for skin color, shrunken, and replaced it with feomelanan.Melanin is very important in the body because it is a powerful antioxidant and protects the person from the harmful effects of radiation. So red men are more susceptible to the effects of toxins.Throughout the world today, only two of the hundreds of people have Auburn hair since birth. However, in Northern Europe due to lack of sunlight is much more. Shatenov in Scotland-13%, Ireland-10% and-6% in England. However, recessive gene is often manifested through several generations, and it may have about 40% of the population.According to some scholars the redhead hair colour in humans will disappear from our planet by about the year 2060. Because numerous mixed marriages, the number of carriers of the recessive gene is reduced. But it's not an exact prediction, and it may well be that the Red people will long to be born in Northern Europe.

The disappearance of the red gene
Redheads people are always attracted attention to his unusual color hair. Scientists believe that hair color appeared due to the cloudy weather in Northern Europe.
Animals with red hair or bird feathers of the same color in nature are quite common, but shateny only appeared a few thousand years ago in human society. This was due to a genetic mutation - in the sixteenth chromosome began to work two recessive genes.
Scientists came to the conclusion that the human body was trying to provide themselves with vitamin «D», which is necessary for bone formation and maintenance of normal metabolism. For the synthesis of the vitamin should be long-term exposure to sunlight and the sky of Europe, especially its northern part, is constantly covered with clouds, and the number of sunny days was minimal. Therefore, human skin became lighter and gained greater ability to absorb ultraviolet rays. At the same time it began to change skin color and hair color. As a result, in the body of the northern Europeans pigment melanin, responsible for skin color, it decreased and was replaced feomelanan.
Melanin is very important in the body because it is a powerful antioxidant and protects people from the harmful effects of radiation. Therefore red people are more susceptible to the effects of toxins.
Today, all over the world, only two of the hundreds of people have hair of red color at birth. However, in Northern Europe due to lack of sunlight are many more. Brown in Scotland - 13% in Ireland - 10% and in England - 6%. Nevertheless, recessive gene is often manifested in a few generations, and it may be about 40% of the population.
According to some scholars red hair in humans disappear from our planet about 2060. Because as a result of the many mixed marriages, the number of carriers of the recessive gene is reduced. But this is not an accurate forecast, and it may well be that people will be red for a long time to be born in the northern part of Europe.
