There are more men than women on the earth. Why do scientists predict that men will disappear in the future?

After years of research, scientists have found that the Y chromosome representing men is decreasing day by day. This means that men are getting closer to women and becoming more and more women. Until the masculinity disappears completely. Maybe in a few million years, men will be completely extinct from the earth, and women and robots will rule the earth. American geneticists pointed out in 19 14 that X and Y chromosomes determine the sex of human beings and mammals.

Two sex chromosomes, X and Y, are like two big kebabs, in which X is still intact after hundreds of millions of years of evolution, while Y mysteriously "eats" several pieces every millions of years. Due to the continuous shortening of Y chromosome, the length of Y chromosome is only 1/3 of that of X chromosome, and the number of male genes carried on Y chromosome decreases by 10 every million years, and now it is reduced from 1669 hundreds of millions of years ago to 45.

Breakthroughs in the field of science have promoted the development of all mankind, from the combination of biology and technology to the solution of water crisis, and a series of cutting-edge scientific innovations. So, what will human beings look like in a thousand years? It seems that the era without smart phones has become a distant past.

Everyone is too scared. Another view of the scientific community is that although the Y chromosome will indeed decrease or even disappear, the functional genes in the Y chromosome may degenerate into autosomes. After all, the original X and Y chromosomes also came from chromosomal evolution. Sex-determining functional genes in degenerated autosomes may bring new sex determination system to human beings.
