In lawsuit you ’re incognizant , duck sex is perhaps the singularly horrific event of the beast kingdom , instinct with labyrinthine vagina dentata , explosive erections , and the occasional coquetry withnecrophilia .

Now , two biologists from the University of Massachusetts , Amherst are launching a project to mensurate the speed of the manlike duck erection . Their goal ? To see how speedy - fire duck’s egg member dissemble their procreative evolution .
Biologists Patricia Brennan and Diane Kelly have kicked offthe Duck Force project at Rocket Hubto call forth pecuniary resource to explore the terrific upper of duck’s egg intercourse . Here ’s their cut-rate sale pitch :
A duck pool in the breeding time of year is like a I bar on steroids — rife with sexual conflict . Males and females pair off , but manlike ducks also force sexual urge on females that are not their mates , sometimes injuring or even killing them .
A few years ago , one of us ( Patty Brennan ) discovered that these extreme intimate behaviour have trigger off an evolutionary limb race between male and distaff ducks – a race that has changed the shape of their generative organs . Females acquire twisty , complicated oviducts that make it hard for Male to put sperm near their eggs . Males countered by evolving long and twisty penises that rapidly billow inside the oviduct . The bends and blind back street in the oviduct seem to be effective at keeping out spermatozoon from undesirable males . But during one of her experimentation , Patty notice that an inflating drake ’s phallus could burst through a silicone modelling of an Fallopian tube .
That made her wonder whether the forces make by explosive inversion could be one factor driving the evolution of the female ’s twisty uterine tube . To find out , Patty is teaming up with biomechanics expert Diane Kelly to value the velocity and force of the inflate duck penis and determine how it might impact the female person ’s reproductive parcel .
Your contributions will lease us journey to a farm in Quebec , Canada that has train manlike ducks to allow for spermatozoan for artificial insemination . We will let these ducks copulate with a series of diaphanous example oviducts fitted with force transducers – the process is harmless to the ducks , and is n’t much different from the style the Fannie Merritt Farmer garner spermatozoon . As each duck everts his member , we will simultaneously shoot it with high - pep pill telecasting and metre how intemperately it hits the bulwark of the model oviduct [ … ] If successful , this project will provide the first elaborate measurements of the forcible forcefulness generated by a penis during copulation . It will take the first step toward examination whether coital forces help drive the evolution of those unhinged eddy in the female ’s oviduct . We expect to present these results in talking at scientific conference and compose them up in a paper for a compeer - reexamine scientific diary .
Again , here’sthe Duck Force project ’s site . Now you really hump why life is like a hurricane inDuckburg .
