As weird as it gets. 😂 Genitalia morphology in waterfowl. Antagonistic coevolution as a result of forced extra pair copulations leads to the evolution of cryptic female choice morphology. https://t.co/W0zqUdH5vd

@DensetsuManth @goodapplejokes @AceViper141 @crazyclipsonly Yeah and the females have maze vaginas. It’s crazy https://t.co/vxfzgxnYEY
Discussed this phenomenal paper on waterfowl genital coevolution in @sunyoswego Ornithology today. This was one of my student's comments. @sexinnature can you confirm that you were, in fact, "hyped"? https://t.co/jQaFOKyaQ0 https://t.co/KWQRpjjhOr
@Zen_of_Science @ASABeducation @IsaRossellini Me too! The perfect complement to Brennan's paper on them https://t.co/IoMW9DUiqN

This remains one of the absolute coolest bird studies ever done. Amazing work on the coevolutionary arms race between male and female waterfowl genitalia by @sexinnature. On the Ornithology syllabus for this semester! https://t.co/jQaFOKyaQ0
We know this is a case of coevolution because scientists have compared the penises of waterfowl that do/do not exhibit forced copulation. No forced copulation=short penis. Forced copulation: crazy corkscrew. https://t.co/Z5jTFBK3qZ https://t.co/tuYkbrR3Oc
@LawyerDave1 @Kaptain_Kobold @AstroKirsten Believable. "These vaginal structures appear to function to exclude the intromission of the counter-clockwise spiralling male phallus without female cooperation." ie Why waterfowl co-evolve tricky vaginas to kee
#Duck #Penises are notoriously screwy. Duck vaginas screw the opposite way. The girls evolved like this to reduce fertilisation from 'forced copulation' So... what's the evolutionary explanation for men's #Y_Fronts? https://t.co/qCa4Ij7XR7

The male and female genitalia of ducks have evolved in a war of the sexes. The twisted labyrinth of a female’s clenched oviduct helps prevent unwanted pregnancies from rapists, while long, coiled penises have evolved to try and crack the maze https://t.co
