In five million years, men could disappear from the face of the planet, says Jenny graves, a scientist from Australia. He studied the structural features of the Y-chromosomes of men and came to the conclusion that this structure is subject to more rapid changes than the rest of the chromosome. Any environmental factor can damage genes.

Jenny graves talks about his theory. In a healthy X-chromosome contains more than a thousand working genes. As many genes originally were and in the Y-chromosome, however, in the process of evolution part of it collapsed. Now in the Y-chromosome has about 100 genes.

The ratio of births of boys and girls will gradually change, until women make up 100% of the population of the planet. It will happen or not, can only show the time.
