Men becomning extinct!

It is no secret that men are basically genetically modified women - the female being the fall-back developmental pathway for any foetus. The evolution of the two sexes could indeed be regarded as a long-running GM experiment.

Its legacy has been to endow men and women with different, and often conflicting, sets of genetic interests, and to ignite a powerful evolutionary struggle, which has accentuated the differences between the two sexes. In several respects, the experiment that gave us men is not going too well just now. Though it is a weary lament to lay most acts of violence and aggression, from the strictly local to the truly global, squarely at the feet of men, the association is strong, consistent and undeniable. Women very rarely commit violent crimes, become tyrants or start wars.

The experiment has created two irreconciliable genetic combatants. On the female side is mitochondrial DNA, which can only be passed down the maternal line. On the male side is the Y-chromosome, which is always passed from father to son. But while mitochondrial DNA is a model of slimmed-down efficiency, the Y-chromosome is a shambles, battered by mutation and going downhill fast, before it eventually disappears altogether. On this chromosome resides the single genetic switch (SRY) which, when flicked to "on", prevents human embryos from developing into baby girls and turns them into boys instead. Also spread out on this dying chromosome are the handful of other genes that men need to make fully operational sperm.

We'll be able to fix it if/before it becomes a real problem anyway. Controlling our own evolution isn't that far away, relatively speaking. Besides, unless women evolve to reproduce asexually, it'd be against nature for a species to evolve to where it could no longer reproduce.

DNA is replicated via the same mechanism no matter what chromosome it makes up, and is especially good at fixing errors. There are several methods of proofreading that take place at several steps in the process to keep the error rate very low. Evolution solely by random mutations takes a very, very long time.

If it is all true, I think some kind of adaptation will show up rather than an extinction. When you find something weird in biology that seems to be a disadvantage, there's almost always an advantage that outweighs it. You just have to find it.

I wouldnt have minded being a woman, I'd love a proper pair of 'fun-bubbles'.

It won't happen in our life time.. Trust me...

I agree on that point we will be long gone before this happens... :rofl:

So this theory can be an explaination for homosexuality?

(this question is not ill ment)

Kinda random.. but this is not theory, it is fact. A baby develops by default as a female and (if the proper chromosome is there) continues development onto a male. If I remember high school biology (and that's a big 'if'), human fetuses even have a tail and gills during the early stages of development.

Yeah, and who knows, maybe with enough research we will able to flip on the switch and all my kids can have tails!! :woot: :woot: :woot: :woot:

Correct wording: I would not mind being a woman. hehe

Anyways... Me too! I would love to tease men.

This whole argument is silly. The whole two-sex thing has been the most evolutionarily advantageous development as far as life on earth goes. It's not going anywhere. :rofl:

Ahhh, the good old forster post :D I couldn't agree any more man! :yes: :D

Anyways... by the time men are extinct, I won't even be around anyways... and besides, I don't think scientists should mess with the evolution. If men are supposed to get extinct, so be it. Nature will find another way, it won't be the end of the world. Everyone will get used to it.

If the cavemen even knew that in million of years, they would look as we look right now, they'd be ****ed off... Like: "Oh noes! What's going to happen to my hair!?"... But they got over it, it's just the natural way.

And... that was really kind of a weird explanation, but I don't know how else to say it :p Lol it's late already :p

So what about true Hermaphrodites?

Do they have the best of both world then.

congenital condition known as "True Hermaphroditism" [intersex] with undescended, sub-sized ovotestes i.e. "gonadal mosaicism" found in approximately 1-in-25,000 births.

the men who are unable to create healthy sperms will not be able to reproduce, and the men that can, will.

I think that research into human reproduction is dangerous. We can now help people who are unable to have children to get them. This may be a bad idea. In nature these people would be among the "weak" genetically speaking and would not have their genes passed along. I'm not trying to be mean, but thats how we got here. Best of the best go on to make better. Anyway, consequences of current actions will not be known for many generations (which is one downside to anything we do to humans), but that doesn't mean we shouldn't be worried.

Letting genetic extinction pass by us without trying to understand it would be like polluting the world and not caring...oh wait
