Women with double uteruses

[Broomstick]

How in the blazing solar hell does that work, mechanically speaking? Does such a woman also have two cervixes (cervixi? What the smeg is the plural of "cervix", anyway?), and both are attached to the vagina, are they arranged in-line somehow?

My mind is boggling here, but I'm too chicken to image Google it.

Yes, it usually, but does not always, involve two cervices (there's your correct plural, by the way). There have been cases where a woman with this condition also has two vaginas. Typically, each of the two uteri only connect to one fallopian tube.

So, like, side-by-side then, each one getting one supply of eggs and forking into one vaginal canal?

Okay. A bit creepy, but...

Hang on, two whole vaginas? Like, a full duplication of the reproductive plumbing below the ovaries?

Was that side-by-side too, or in-line front-to-back, or...

Keep in mind, with a developmental disorder (which is what this is) you're talking about a spectrum. I think (we're getting to the edges of my knowledge, and a perusal of my sister's medical library this week unfortunately did not further enlighten me on this matter) that usually the two uterii are side by side though it's probably possible to have a set front-to-back.

The double vagina could be anything from a double cervix at the end of a tube to two complete vaginas with separate openings, though I'd expect most cases to be somewhere in between. If the fork where the single vagina becomes two occurs high enough up the vaginal canal the woman and her sexual partners might never be aware of her difference, unless they were heavily into playing with speculums during sex.

Some of these modern (last 2000 years) 'mutations' that humans are experiencing are very interesting.

What makes you think this is a recent "mutation"? Don't you think this occurs in other species as well?

Has our modenisation inhibated our evolution?

Fuck no - but I don't expect you to understand that we are evolving on a celluar as well as a bodily level. So far, you haven't demonstrated a great deal of either knowledge or willingness to learn.

A double uterus makes perfect sense in a pre-modern medicine world, ie:

Humans have sex alot (no research but I assume because of the pleasure we have pretty much always had lots of sex)
Baby deaths are rampant (in a pre-modern medicine world)
Survival of the fittest (darwin, theory of evolution)

So I guess, in a non-modernised world, a double uterus would likely of become more prevalent? Or does it cause more problems than it solves?

Are you posting drunk again?

You are a moron. ANY pregnancy in a human female with more than one fetus is at higher risk than a single birth even with the most modern and sophisticated medical science. Twins are vastly more likely to be premature, something that was often fatal in pre-modern medicine. Fuck, yes, double uterii cause problems. Haven't you read what's been posted about increased risk of miscarriage in a women with a double uterus even when carrying only one child?.

What makes for evolutionary fitness is what maximizes the number of single births a woman can raise to adulthood - not the sheer number of babies she can squirt out, because if they're all premature or underweight they won't survive and said woman is an evolutionary dead end.
