Skip to comments.Male Sex Chromosome Losing Genes By Rapid Evolution, Study Reveals
Posted on 07/18/2009 9:31:08 AM PDT by steve-b
Scientists have long suspected that the sex chromosome that only males carry is deteriorating and could disappear entirely within a few million years, but until now, no one has understood the evolutionary processes that control this chromosome's demise. Now, a pair of Penn State scientists has discovered that this sex chromosome, the Y chromosome, has evolved at a much more rapid pace than its partner chromosome, the X chromosome, which both males and females carry.
This rapid evolution of the Y chromosome has led to a dramatic loss of genes on the Y chromosome at a rate that, if maintained, eventually could lead to the Y chromosome's complete disappearance....

This explains Charlie Crist.
LOL! Richard Burr ...
“Even though some of the genes appear to be important, we still think there is a chance that the Y chromosome eventually could disappear,” said Makova. “If this happens, it won’t be the end of males. Instead, a new pair of non-sex chromosomes likely will start on the path to becoming sex chromosomes.”
been saying for some time that men nowadays especially left wing men are girlie.
I just hope that my daughter will be able to find a guy who is a man when she gets older and not some tip toeing tulip skipper.
Even look around at the men who fought in the second world war and then look at the young men say in Boston.
one is manly the other cares more about how his nails looks, his hair looks and thinks he can give a finger to others while in his car but gets all upset if he is confronted with a promise to break that finger if he ever does it again
Both responses are ironic in that they both played football at Wake Forest.
So, by admission, science is saying that males are more evolved. This is borne out anthropologically, in other observations, such extended childhood development, long a known trait of species with higher intelligence.
But, in a genuflection before political correctness, this evolution is interpreted as actually not a beneficial mutation, leading to the extinction of males.
You just can’t make this crap up. Round and round it goes.
Wishful thinking to get more man-hating feminazis to read the article.
How funny! A boy from my high school class went to Wake Forest on a football scholarship: T.J. Morgan. He’s be past the age for football by now, of course ...
This needs to be put in context with DNA as a whole. That is, there are some fairly primitive creatures, like some worms, that have far more chromosomes than do more advanced animals and man, but beyond a developmental point, a culling process is used to eliminate “extra” chromosomes.
The logic to this is straightforward. Having more chromosomes means that an organism is more adaptable, but it is harder for it to reproduce its DNA in its offspring. So it’s a trade off.
People probably have too many chromosomes, with the Y chromosome being on the weak end, so it is fading away. Importantly, there is a fairly common genetic problem with the X chromosome as well, called “Fragile X Syndrome”, which might result in it becoming the replacement Y chromosome, while another chromosome takes its place. Literally, an “arm” of the X chromosome could “fall off”, leaving it to look like a Y chromosome.

Next the “W Factor” so beloved of birds. With them the Females do all the sex selecting and designating.
Here are some traits that are not going away.
I forgot to mention the ability to enjoy a good cup of coffee.

Based on this Barack Obama will declare a crises and claim that health care legislation passed THIS WEEK to solve this problem before it is to late.....
Y oh y is that happening to me?
Leave me alone, I just want to sit back and enjoy the hysteria.
