Lady ducks have evolved a unique way of avoiding the unwanted advances of, er, enthusiastic suitors, according to Yale scientists.
According to researchers, while male ducks have developed longer, spiraled genitalia, the females' anatomy has evolved to spiral in the opposite direction. “In species where forced copulation is common ... this coevolution results from conflict between the sexes over who is going to control fertilization,” said Yale researcher Patricia L.R. Brennan.
Essentially, female ducks are able to thwart "undesirable but aggressive males" and avoid becoming pregnant because the sexes have evolved mismatched equipment.
Researchers released the study this week detailing this evolutionary battle of the sexes in the current issue of journal Proceedings of the Royal Society B.
This latest paper builds off of a 2007 study that detailed the odd structure of ducks' sexual organs. For this study, scientists (presumably without blushing) examined the male ducks' genitalia in glass tubes meant to simulate the shape of a female's sex organ. Researchers observed that the ducks' incompatible parts prevented pregnancy in the females.
"Ducks are providing us with an incredible opportunity to understand the evolutionary consequences of conflict,” said Brennan.

Oh, boy. The next thing you know liberal women will develop sex organs screwed up. Sheesh@
These scientists are “quacks” AH HA AH HA!!! I made a funny. Wahoooo!!! blblblblblblblblblbl
So if a boy duck from North America gets together with a girl duck from South America, does that line everything up? And what happens to Barney Frank ducks?
Our tax dollars at work.
Sounds like a recipe for crossed-threads.
Thank goodness.
What, are you trolling for grant money, or what?
And that’s why birds do it, bees do it
Even educated fleas do it
Let’s do it, let’s fall in love
Cold Cape Cod clams, ‘gainst their wish, do it
Even lazy jellyfish do it
Let’s do it, let’s fall in love
I’ve heard that lizards and frogs do it
Layin’ on a rock
They say that roosters do it
With a doodle and cock
Some Argentines, without means do it
I hear even Boston beans do it
Let’s do it, let’s fall in love
Someone, please tell me we didn’t pay tax money for this.
“XXXX a duck!!!” would seem to be more complicated than most folks realize ....
Of course we did.

“...what happens to Barney Frank ducks?”
Birds do everything through the same orifice, so it’s too hard to distinguish one from the other.
From “Life, the Universe and Everything” by Douglas Adams:
“The party and the Krikkit warship looked, in their writhings, a little like two ducks, one of which is trying to make a third duck inside the second duck, whilst the second duck is trying very hard to explain that it doesn’t feel ready for a third duck right now, is uncertain that it would want any putative third duck to be made by this particular first duck anyway, and certainly not whilst it, the second duck, was busy flying.”
Groan!
Lemme just make a wild guess here: This woman is a member of NARAL and NOW.
Even in so-called “science’ the FemiNazi’s are still at work with their anti-male agenda.
LOL. Grant money is always welcome. I’ll work on the northern hemisphere, southern hemisphere question; the Barney Frank question is available for other researchers.
All these tax dollars spend on research only to discover that women get screwed in the end.
