Claims are made in many reports regarding the extinction of life on Earth. But have you ever heard about any such report, which talks about the disappearance of men from the earth? Surely, you might not have heard of this before, but recently scientists have released a similar report. It has been said in this report that in the coming years, birth of boys will stop on earth. That means only girls will be born. According to this report, the Y chromosome found in men is gradually shrinking and there will come a time when it may disappear completely. Let us tell you that Y chromosome is important for determining male gender. In such a situation, its disappearance means that only girls and not boys will be born on earth.
Actually, humans and mammals have two chromosomes, X and Y, which determine sex. That is, due to X and Y chromosomes it is known who is a boy and who is a girl. Where X determines the gender of girls and Y of boys. But according to this research published in the Proceedings of the National Academy of Sciences, the Y chromosome is gradually weakening. In such a situation, the population of men will keep decreasing and after millions of years they will become extinct. Let us tell you that the Y chromosome is very small, on which there are only 45 genes and there is only one gene which makes a male. However, this was not always the case. Earlier the Y chromosome contained 900 genes instead of 45. But these are decreasing. There will come a time when these genes will become completely zero. Then men will not procreate on earth.
Australian geneticist Jenny Graves told Science Focus that there are a few reasons for this. First, the Y chromosome is in the testicle and never in the ovary. But the testicles are not a safe place to live, because many mutations keep happening in them. Graves further explained, “To make sperm, a lot of cell divisions are required and each cell division is a chance for mutation. This can have a great impact on the chromosomes. It’s also not very good at repairing itself, because the cell only has one gene. By now the Y chromosome has lost 97% of its ancestral genes. At the same time,
However, Graves further said that men should not panic because of this. There is still some time left, which is about 70 lakh years. From an evolutionary point of view the decline has been quite rapid. Chromosomes first evolved 180 million years ago and it has taken that long to get to this point. According to Graves, it is strange that people become so upset by the loss of the Y chromosome. My rough estimate is that there are still six or seven million years left for the complete extinction of the chromosomes. But it is possible that a new sex determination gene may develop in our body, as has been seen in some organisms. But whatever Jenny Graves says, this report related to the disappearance of men is a matter of concern.
