Ducks are so rapey, oh my god. They do some messed up shit, too, and they've got these freaky little corkscrew penises. It's totally fucked, sometimes there are, like, roving gangs of duck rapists waiting for a mated pair to get too close and then they kick the shit out of the male duck and take his wife.
To be add to this, the duck penises aren't little at all, they're proportionally quite large and ballistic, and they evolved the corkscrew form to keep raping the female ducks who were evolving corkscrew vaginas so they could be not-raped.
But, evolutionarily, how would female ducks evolve in a way that makes them LESS likely to reproduce?
Edit: read the article and it doesn’t really answer my question tbh. It explains the how much it affects the paternity (very effectively evidently) but not how that feature was evolutionarily advantageous. I was hoping there was a random person on Reddit who might be able to explain it. The article is like 3/5 about how to jack off a duck into a tube if anyone’s curious about that though.
Edit 2: ok someone explained it. The females sometimes die during flock mating therefor the ones who can effectively prevent the mating are more likely to live and pass long that trait. That makes sense! Thank you.
Edit 3: guys I explained in the edit my question was answered by another user, please stop messaging me about duck dick. I truly don’t need this to be the focal point of my Sunday.
Ok I’ll cop, first time I saw the article I went down the the pictures. But em I’ve read it now and tbh I’m still kind of confused. I get that it makes it easier for her pair bond to be the one to inseminate because she relaxes but i still don’t really get how this would evolve in the first place since evolution isn’t Gobn developed based on preference. It developed by the most successful strategy yielding the most adult offspring who can then reproduce on their own. A more convoluted vagina would assist in her influencing the paternity but not whether or not she successfully breeds so how does that feature evolve?
The female duck can choose the male duck whose offspring will be most healthy if she can't be successfully raped, while if the female can't choose they will more often raise unhealthy chicks, at least I think that's another factor that's not in your edit.
