Men's sex chromosome is doomed: scientist

THE poorly designed Y chromosome that makes men is degrading rapidly and will disappear, even if humans are still around.

Evolutionary geneticist Jenny Graves says while the process is likely to happen within the next five million years it could have begun in some isolated groups.

"As long as something came along it its stead, we would not even suspect without checking the chromosomes," she told AAP on Tuesday.

Professor Groves, who first made the prediction some years ago, was in Canberra to give a public lecture on the subject for the Australian Academy of Science.

There have been dissenting research papers, but her prediction hasn't changed.

"Its very bad news for all the men here," she told her audience.

Prof Graves has been studying sex-determining genes in Australian animals to shed light on human genetics.

"You would think that sex is so important it wouldn't change a lot. But it changes all over the place and the Y chromosome sort of self-destructs," she told AAP.
