In the New Year’s holidays, many media were intimidated its subscribers male imminent extinction of what was called the cause of the loss of the Y-chromosome, which is supposedly almost completely destroyed in the process of evolution. However, many media for sensational news was added various details, citing statements by the Oxford professor Bryan Sykes, who believes that the male population will disappear from the face of the earth after 125 thousand years. But what is even more interesting – scientists have thought that the broken function of Y-chromosome will take over certain third chromosome that will be the birth of a new creature, likely hermaphrodite.
Experts from our website Express News , in trying to understand what prompted scientists to think of a similar nature, concluded that this statement still has some grain of truth. In particular, it is a proven fact that the Y-chromosome is initially contained a 1.4 thousands of genes, while at the moment it contains only 72 genes capable of encoding proteins. However, such changes have taken place in a relatively long period, roughly 160-210 mln. Years. On the other hand, if we assume that this chromosome in the future will also lose their genes somewhere over 10 million. Years, it may lose its function.
After analyzing the research data, the experts were able to prove that Over the past 25 million years of the Y-chromosome has lost its only one gene. At the same time, for the last 6-7 million years it has not lost a single gene. Thus, using linear extrapolation model, the researchers came to the conclusion that the nearest 10 million. O man extinction is hardly to be feared.
