Women may think of men as primitive, but new research indicates that the Y chromosome - the thing that makes a man male - is evolving far faster than the rest of the human genetic code.
A new study comparing the Y chromosomes from humans and chimpanzees, our nearest living relatives, show that they are about 30 per cent different. That is far greater than the 2 per cent difference between the rest of the human genetic code and that of the chimp's, according to a study appearing online Wednesday in the journal Nature. These changes occurred in the last 6 million years or so, relatively recently when it comes to evolution. "The Y chromosome appears to be the most rapidly evolving of the human chromosomes," said study co-author Dr. David Page, director of the prestigious Whitehead Institute and a professor of biology at Massachusetts Institute of Technology. "It's an almost ongoing churning of gene reconstruction. It's like a house that's constantly being rebuilt."
Before men get too impressed with themselves, lead author Jennifer Hughes offers some words of caution: Just because the Y chromosome, which determines gender, is evolving at a speedy rate it doesn't necessarily mean men themselves are more evolved.
Researchers took the most detailed examination of the Y chromosome, which females do not have, of both humans and chimps and found entire sections dramatically different. There were even entire genes on the human Y chromosome that weren't on the chimp, said Hughes, also of the Whitehead Institute. [SNIP] Until recently the Y chromosome was considered the unassuming figure in genetics. [SNIP] A few years ago some researchers even suggested that the Y chromosome was shrinking so that in 50,000 years it would just disappear - and so would men.

Still, for some, men are just lowly sperm donors.

Waddya think, that we kill each other off so fast for nothing?
Excel or don't get laid, baby (not that females have anything to do with that).
I guess this means women are the primitive ones...since they lack the most highly evolved chromosome of all.
>> Another reason has to do with the nature of mating. When female chimps are in heat, they mate frequently and with many partners, so there is an evolutionary pressure on the male to produce the most and best sperm to propagate his genes, Page said.
(cough)
If women think the world would be so much better off without men, if that were to happen, it would be hell on earth.
Who’s going to listen to the women complaining about whatever isn’t perfect that’s bothering them at that moment? Other women? Not likely. Listening to gossip/small talk is one thing, listening to another woman complain about the big and small things (probably a lot of things that’s bugging them personally, too), totally different.
IIRC, the Y chromosome recombines with itself. Perhaps that has something to do with it.
But we have been a successful sex, why would that success disappear? Isn't that de-evolution or some such? Evolution sure is confusing. A biology teacher friend told me (with a smile) the most common phrase in evolution circles is "you don't understand how evolution works". No wonder.
I’m glad I was not a part of this study because I don’t believe I have evolved much further than Cain and Able. Sometimes when I hear my dear liberal brothers speak I want to pick up a rock and just clunk them on the head.
Maybe the fact that I don’t indicates that I have evolved some. It could also mean I have an ill informed idea of what prison life is like and I fear that it is not conducive to the happy or healthy lifestyle of a heterosexual American male and the strong desire to avoid it overrules all other emotions.
as a woman i am glad to hear the y chromosome is not leaving. however, i personally like men who are a bit primitive. i have no interest in those highly polished metrosexual morons who cannot change a tire, use a chainsaw, run a cordless drill without a trip to the e.r., or split wood with a maul. the pantywaist who tells his pms-ing wife he knows how she feels and understands her being so irrational should never procreate. thank God for primitive men...every sweaty, smelly, belching, manly inch of them.

I think I’m in love.

Happily married to an ugly, hairy biker warrior who can fix ~anything~, including a broken heart *ping*....:)
FYI
Does this mean that women are less evolved; that they are closer to chimps than men are?
[Another reason has to do with the nature of mating. When female chimps are in heat, they mate frequently and with many partners, so there is an evolutionary pressure on the male to produce the most and best sperm to propagate his genes, Page said.
To test this out, Hughes said she hopes to soon examine the Y chromosomes of a rhesus macaque, which is fairly promiscuous, and the marmoset, which is more monogamous than early humans probably were.]
Hmmmm, I see signs of wild monkey sex.
