The Y Chromosome Is Vanishing. A New Sex Gene Could Be The Future of Men

The sex of human and other mammal babies is decided by a male-determining gene on the Y chromosome. But the human Y chromosome is degenerating and may disappear in a few million years, leading to our extinction unless we evolve a new sex gene.
Most mammals have an X and Y chromosome similar to ours; an X with lots of genes, and a Y with SRY plus a few others. This system comes with problems because of the unequal dosage of X genes in males and females.
How did such a weird system evolve? The surprising finding is that Australia's platypus has completely different sex chromosomes, more like those of birds.

Actually there was recent study that said our "Y" chronosome was surprising stable and durable. That study theorizes (and all these studies are presenting their theorys - they're hypothesis') it is not 'degrading' but continuing to evolve similar to the evolution found in the genus of platypus and echidna.

It's science but it is not yet fact.
