Analysis of the chromosomes on archeological material has shown that the X chromosome is roughly 80 000 years older than the Y chromosome. Thus it turns out that the male sex chromosome appeared later than the X chromosome.The most widespread model of the origin of the Y chromosome is from the autosome (a nonsexual chromosome). As a result, the X and Y chromosome don‘t recombine correctly and this leads to the degradation of the Y chromosome. Some researchers have concluded that the period when there was no Y chromosome yet mankind was made up of only women. However there were different categories of women: the usual normal women who had children, but also hermaphrodites with female phenotypes. Men developed from the latter category of women. One of the X chromosomes gradually lost fragments and turned into a Y chromosome containing less than 100 genes.It has been found out that a polluted environment especially affects the Y chromosome.There are fewer and fewer normal men. There is a female illness that the doctors call prolapsus of the uterus. We think that this isn’t an illness but a stage of evolution when women begin to acquire male signs. The existence of hermaphroditic people in ancient times is confirmed by the analysis if several drawing in which people with female breasts and a male sex organs are depicted. The degradation of the Y chromosome is bringing about the modification of the male gender. Because of the degradation of the Y chromosome the number of boys being born may go down.
