The Male Y Chromosome May Be Disappearing

There’s new information, at least theoretically, that the male Y chromosome could be disappearing. This work was done at Penn State. It’s in the journal PLoS Genetics. Researchers say there is a dramatic loss of genes from the human Y chromosome and it could eventually lead to its complete disappearance over the next million years or so. While some genes seem to be essential, like those for sperm development, most have been lost and the researchers say that they found evidence that many are on a track to disappear as well. If this happens, researchers say a new pair of chromosomes will likely start down the path of becoming X and Y sex chromosomes. It’s pretty fascinating how you can actually see mutations occur, but this is essentially how the world has developed; changes and development. With those differences came different people.
