Biologists Debunk the "Rotting Y Chromosome" Theory

An anonymous reader writes "Biologists have previously predicted that that the male sex-determining Y chromosome, which once carried around 800 genes, like the X, has lost hundreds of them over the past 300 million years, will mutate itself out of existence, leading to the eventual extinction of men. However, researchers of a study published in the latest issue of Nature found evidence to suggest that the Y chromosome will not shed any more of the 19 ancestral genes that it is left with."

Re:Both sexes are valuable

What a load of nothing that article was.

However, the effects of selection are not ignorable in a large population for nearly neutral mutations.

Like what? What about color blindness? How is that selecting? A non beneficial mutation that has no bearing on survivability!
I still contest that evolution has no answer to the fact that most mutations must be non beneficial and thus cannot descibe the extreme amount of order present in life on earth.
