Sneering Feminist Misandrists Who Claim Men Are Less Evolved Than Women Have Egg On Their Faces

Not too long ago some feminists spoke hopefully of the ultimate demise of the purportedly "less evolved" male gender. Just another example of how taking what feminists say seriously leads to delusions that end up bringing embarrassment..

Men more evolved? Y chromosome study stirs debate
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 percent different. That is far greater than the 2 percent 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 in Cambridge and a professor of biology at MIT. "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.

The two-year research took twice as long as expected because of the evolutionary changes found, Hughes said.

There is a bit of a proviso to the comparison to other chromosomes. While all human and chimp chromosomes have been mapped, only two chimp
chromosomes have been examined in great detail: Y and chromosome 21. Yet, there's still enough known to make the claim that the Y is the speediest evolver, Hughes and Page said.

Until recently the Y chromosome was considered the Rodney Dangerfield of genetics, especially because it had fewer genes than other chromosomes. 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.

"The story is not as cut and dried as many would have liked to predict," Hughes said. "It's kind of fun to say that men are going to die out, but the science is proving — now that we've got data — that that's not true at all."

Why the Y chromosome is a hotbed for evolution
Mark Henderson, Science Editor

The Y chromosome is often seen as the rotten corner of the human
genome — a place of evolutionary decline that is slowly decaying
and threatening the end of man. Reports of its imminent demise,
however, have been exaggerated.

Research has indicated that, far from stagnating, the male
chromosome is a hotspot of evolution that is changing more quickly
than any other part of humanity’s genetic code.

In most mammals the sex of offspring is determined by X and Y
chromosomes. Females have two Xs, males have one X and one Y
— with the Y making them male. The Y was originally identical to
the X, but over 300 million years it has shrunk, and is now the
smallest human chromosome.

This is because it occurs on its own, and cannot swap genes to
maintain integrity. This decline has led scientists to suggest it would
waste away entirely in 125,000 years or so. This would mean the
end of men, and probably of humanity.

But the first comparison of the human Y chromosome with its
counterpart in chimpanzees has revealed that they differ radically.
The findings suggest that the Y chromosomes of both are evolving
rapidly and dynamically — probably because of their critical roles in
reproduction — and have a vibrant future.

In the new research, which is published in the journal Nature, Dr
David Page, of the Massachusetts Institute of Technology — who
first sequenced the Y chromosome in 2003 — has now sequenced
the Y chromosome of the chimp, humanity’s closest relative, and
compared this with the human version.

The scientists expected the two sequences to look very similar.
However, while human and chimp DNA generally differ by less than
2 per cent, more than 30 per cent of the Y chromosome differed
between the two species.

“This research shows that the Y chromosome isn’t necessarily
degrading, but is evolving very fast,” said Professor Robin Lovell-
Badge, of the National Institute for Medical Research in London, an
expert on the Y chromosome. who was not involved in the study.

Dr Page likened the process to a home that is constantly under
renovation. “People are living in the house, but there’s always some
room that’s being demolished and reconstructed,” he said. “This is
not the norm for the genome as a whole.” Several factors probably
account for the rapid evolution of the Y chromosome. First, the trick
it uses to repair genes — known as gene conversion — is probably
less efficient than the repair mechanisms used elsewhere in the
genome. This allows new mutations to arise more often.

These mutations are then subject to greater selective pressure than
the rest of the genome — because of the important role of the Y
chromosome in ***** production. Any advantageous mutations
would be expected to be preserved as they boost fertility, while
deleterious ones would be rapidly flushed from the gene pool 

This is supported by the discovery that the parts of the chromosome
involved in ***** production are most different between humans
and chimps.

Wes Warren, of Washington University in St Louis, Missouri, who
contributed to the study, said: “This work clearly shows that the Y is
pretty ingenious at using different tools than the rest of the genome
to maintain diversity of genes. These findings demonstrate that our
knowledge of the Y chromosome is still advancing.”
  
 

Conceptualclarity : Personally I don't place much practical significance on these findings. I'm just tickled to see another piece of the feminist teaching of contempt for men dramatically undermined.

I agree with the assertions in these findings and believe that knowledge needs to be understood in an ongoing context. Always in a state of discovery and flux; never static. Necessitating constantly changing conclusions to match. Women are constantly clamoring for us men to change right? Well, there it is: built-in designed adaptability and “evolving very fast” as good Professor Lovell-Badge contends. Robust in its tendency towards diversity. An excellent find CC, however attempting to explain the study’s ramifications of these findings to Y chromosome bashers is an entirely different matter. Square pegs are not so conducive to round holes.<br />

Btw, for argument’s sake – if homo neanderthalis/cro-magnon males dragged their knuckles, it makes sense that the female of the species also dragged them as well.

Exactly. Human beings - men and women alike - are the same species and have therefore reached precisely the same level of evolution.
