A leading female scientist, Professor Jenny Graves claims men are heading for extinction....the
bad news doesn't end there, because the process may have already
started....lol....this is quite serious.
Professor Graves, one of Australia’s most influential scientists,
believes that women will win the battle of the sexes – and in the most
definitive way possible.
She says that the inherent fragility of the
male sex chromosome, the Y
sex chromosome, means that men are sliding towards extinction.
Professor Graves’s prediction hinges around the number of genes on the male and female sex chromosomes.
The female, or X, chromosome, contains a healthy 1,000 or so genes.
What's more, girls and women have two of them.
The Y chromosome started off with as many genes as its female
counterpart.
But over hundreds of millions of years it has crumbled away, leaving
fewer than 100 genes in modern man.
This includes the SRY gene, the ‘male master switch’ that determines
whether an embryo is male or female.
What is more, while women have two X chromosomes, men have just one,
‘wimpy’, Y.
This is key, as the pairing allows the X to make crucial repairs.
Lacking a mate, the Y chromosome finds it more difficult to patch up
mistakes and so decays away.
Professor Graves, of Canberra University, said: ‘The X chromosome is all
alone in the male but in the female it has a friend, so it can swop
bits and repair itself.
‘If the Y gets hit, it’s a downward spiral.’
Giving a public lecture, the professor said: ‘It is very bad news for all the men here.’
And there is more bad news.
In her talk at the Australian Academy of Science, the professor
described the remaining genes on the Y chromosome as being mostly ‘junk’.
She said: ‘It’s a lovely example of what I call dumb design.‘It’s an evolutionary accident.’
However, there is some good news.
Professor Graves estimates that it will take five million years for the Y
chromosome, and the men it produces, to disappear all together.
