Y chromosome, It plays a sex-determining role in mammals. As a result of a new study, scientists predict that the Y chromosome will deteriorate over time and could disappear completely within a few million years. This means that if a new evolution of sex genetics It means that if we don’t, the human species could be threatened.

A study published in the journal Proceedings of the National Academy of Sciences showed how spiny mice in Japan survived after losing their Y chromosome.

Is there an evolutionary change in the Y chromosome?

Researchers found that most of the genes on the Y chromosome of spiny mice had been moved to other chromosomes, with the Y chromosome being replaced by a new genetic rearrangement. This genetic change is male gender marking It retains its function and this change proves that even species lacking the Y chromosome can survive. In the study SOX9 The role of the so-called gene and that a new genetic change may be part of this process is emphasized.

In the future disappearance of the Y chromosome What could it mean for the human species? If a new sex-determining gene were to emerge, it could ensure the survival of the human species. However, it is thought that this process would entail several risks and that different genetic systems could develop in different regions. Such a situation could also lead to the emergence of new human species. After 11 million years, it might be possible to see different types of humans on Earth, or perhaps no humans at all.
