German scientists have confirmed the theory that on our on the planet, the number of women has always exceeded the number of men, despite the fact that more boys are born than girls. However soon the trend may change. Specialists from the Institute Max Planck Evolutionary Anthropology (Germany) introduced the results of his study of the demographic history of mankind in the journal Investigative Genetics. For their study, they used a new technique for extracting genetic information. IN as a result of data processing, scientists found that, despite the fact that boys were always born more than girls, women even in tribes of the ancestors of modern man has always been significantly more than men. This was partly due to early mortality. boys. As a result of the numerical superiority of women over men, such a tendency as polygamy could take shape. IN As a result, it was women who “gave” their descendants the greatest the number of genes compared to men. However, scientists warn that the number of women on Earth will be steadily shrink, and this phenomenon poses a threat to the future of humanity. According to recent studies in the world is increasing the number of single women, despite the fact that for every hundred babies 114-116 boys are born to women. “In fact, everything much harder than it sounds. For some time in the world, for example, in China and India, in general, more boys are born than girls. But this is explained not by the mysterious intentions of nature, but by the subtle calculation of the parents themselves. In the same China, when the family can have only one child, boys are preferred. Girls are often disposed of immediately after an ultrasound scan. In India, a girl still, in a way, a burden for the family. Not only is she you need to prepare a good dowry for marriage, so she also will go to another family, will not save the clan’s surname, and will not be able to take care of parents when they are old. There are many theories about the balance of newborn boys and girls. there is countries in which many more boys are traditionally born, and this advantage remains constant. This is, first and foremost, Islamic countries. There preponderance of men over women and remains at a ratio of 1.5 or 2.3 to 1. This is because these countries have led for centuries war, and the reproduction of men has been steadily increasing dominant. And also it is explained not by the best and disenfranchised the situation in these regions of women, where the mortality of the “weaker sex” taller than men these days. Popular – boys more often born to war, and girls to peacetime. But I would say that men portend general variability, and women a certain constancy. It so happened. True, I already anticipate how almost everyone is surprised: if more boys are born, why then in old age on the benches some grandmothers are sitting? This is easily explained: the mortality rate among young men is an order of magnitude higher than that of girls of the same age. In addition, the total duration life in men is still lower. But I’m definitely happy with the fact that in our country there are no, as such, fundamental preferences regarding the gender of the child. “Anastasia Kalinina, sociologist, demographer, anthropologist
