Because we aren't as inherently nifty as cephalopods? *waves at PZ*

Meh. Speaking as a mother of two children, I'd prefer it if we were marsupials. Or better yet, I wish the whole "the story brought 'em" thing was true. Pregnancy + childbirth = argh.

As an aside: Pharyngula rules.

The vagina is an entirely new structure, which has no homolog in amphibians or reptiles.

Uh huhhuh, huhuhuhuh. He said, "homolog." Huhhuhuhuh. Uh huhuhuh.

Marsupials: The female has two vaginas, both of which open externally through one orifice but lead to different compartments within the uterus. Males usually have a two-pronged penis which corresponds to the females' two vaginas. (wikipedia)

I think we've solved the "Grow a pair" debate.

What a coincidence. I was just researching this topic. Need more primary sources though.

Q: why do female mammals have vaginas?
A: because of HoxA-13

I did not find that answer interesting. But then I'm not a geneticist.

Thinking of somebody I once knew, the answer I flashed on was "because 'motorcycle parking lot' was already taken."

This is really interesting.

Good link; I hadn't known about these so-called ScienceBlogs(TM) before... many or all of which appear to be written by bona-fide academics.

I didn't know science professors had discovered blogs...

That's not polarized, is it? If you touch them during intercourse, would you get a shock?

Would they?

Or would they be kinda into that?

I'll be in my bunk.

It is rather reminiscent of the shocker.

Can I just say that I love that the abbreviated vag has been used in link (evolution_of_the_mammalian_vag.php) They couldn't have snuck in vah-jay-jay instead?

Asherah: Hate to spoil your fun, but they probably just truncate story titles at 30 characters for their page names.

Why would that surprise you? Some of us have even discovered Metafilter. (Even before you did, to judge from your user number)

I'll quote the article:

Everything gets dumped in to the cavity of the cloaca, making a nice stew of feces, urine, and sperm or eggs. Mmm-mmm.

I'll quote the article again, this time pointing out what's wrong:

Put your tongue on it and the taste is reminiscent of a 9V battery.

Now, see, I have actually said of myself that I didn't have the balls to do something, but. I guess the guy thought people wouldn't be interested in some nice comparative morphology without a little huh-huh-huh entertainment center heh crap. The science is interesting, but the tone bugs me.

Next time you try to stick it in your girlfriend's pooper, and she yells at you, just say "sorry, old evolutionary habit."

I wondered about it for a second and then it occured to me: who would want to play in a vagina that wasn't warm-blooded? And let's face it, despite modern convention, a vagina is supposed to be covered in fur.

This proves there is a god. And she's a mammal. With a vagina. Or something.

Off to drink more to the memory of Andre the Giant. He was a mammal without a vagina.

"The science is interesting, but the tone bugs me."

I can understand that. Wait, there or here?

There, of course.
Here, it's a feature.

Only mammals have 'em. Why?

Maybe fun-holes were originally needed for storing surpluses of mammals' anti-microbial snot mixed in with a lot of fat and sugar?
