According to the Telegraph we men are on the road to extinction as the number of genes on our Y chromosome shrink and fade away.
Mercifully we are not looking at the year after next but according to researcher Professor Jennifer Graves the Y chromosome is dying and could run out within the next five million years.
In a lecture, entitled The Decline and Fall of the Y Chromosome and the Future of Men at the Royal College of Surgeons (RCSI) in Ireland, Professor Graves sad: "You need a Y chromosome to be male," she said “Three hundred million years ago the Y chromosome had about 1,400 genes on it, and now it's only got 45 left, so at this rate we're going to run out of genes on the Y chromosome in about five million years. The Y chromosome is dying and the big question is what happens then."
The male Y chromosome has a gene (SRY) which switches on the development of testis and thus determines maleness. She said it was not known what would happen once the Y chromosome disappeared. "Humans can't become parthenogenetic, like some lizards, because several vital genes must come from the male," she continued. "But the good news is that certain rodent species - the mole voles of Eastern Europe and the country rats of Japan - have no Y chromosome and no SRY gene. Yet there are still plenty of healthy male mole voles and country rats running around. Some other gene must have taken over the job and we'd like to know what that gene is."
Professor Jennifer Graves said men may follow the path of a type of rodent which still manages to reproduce despite not having the vital genes that make up the Y chromosome.
Given the number of women who consider men to be rats then that should not be a problem!
