The Context of Sex

Posted: 01/06/12 12:22 PM ET

Biologists assume that all animals have a few goals in common: survive and reproduce. It doesn't mean much to survive without sending genetic blueprints into future generations, and there is a myriad of weird, ridiculous and awe-inspiring ways in which animals have evolved to do this. In some cases there are hints of romance and genuine partnership, while in other cases sex is best described as masochistic and murderous.

I have written a lot about the various strategies used by animals to spread their genetic seeds. It's a topic that I find tremendously interesting, both as a biologist and as a female member of the human species. We're not the only girls in the animal kingdom who fall for the wrong guys, strategize about finding 'Mr. Right' and occasionally fend off the advances of unwelcome suitors. Like many other ladies, from beetles to chickens to dolphins, we're generally the 'choosy' sex -- a guy has to prove his worth before we'll come out to play. Sometimes males can be sneaky, deceiving us into a sexual encounter that we may not have otherwise undertaken. However, we females can be sneaky too, using post-coital tricks to weed out the sperm of undesirable partners.

My contributions here at The Huffington Post will be a journey into the astonishing reproductive lives of our animal cousins. From chastity belts to birth control pills to cross dressing and homosexuality, diverse sexual strategies are everywhere. Animal sex is not always straightforward, it's not always fun, and sometimes it's downright dangerous! Eat your heart out Carrie Bradshaw -- learning about the Context of Sex in the animal kingdom gives a greater perspective for just how easy we humans have it.

@gutenmorgen that's hillarious! I often joke that in some respects our 'large brains' have facilitated them becoming smaller :) Love the point about mating with small brained men...interestingly, female tree crickets fall for 'bad boys' as well...blog post coming! @jf12 great question, I'm definitely going to look into that. If the parasite could benefit from altered sexual behavior of a host (increased chances to propagate), then it's certainly possible. @justwhendoesitend I agree, sometimes human females can be sneaky too, in a social sense. Though it may not be for a biologically relevant reason...

A number of years ago I was asked by some (male) students: "how will evolution change our species"? I jokingly answered "smaller brains". "Why"? "Look at the mess we have created with our large brains". "How will that come about"? "Don't worry, women will chose mates with smaller brains; the only thing you will contribute is having sex". We then all had a good laughter.

Do parasites affect sexual behavior in any species to the extent that toxoplasmosis affects the predator-prey relationship of cats and mice?

"Sometimes males can be sneaky, deceiving us into a sexual encounter that we may not have otherwise undertaken."

I believe this is equally true of the female gender. I would go further in claiming the female gender is much more advanced in the techniques of being sneaky to nab the male of their choosing. Many times they conspire together to bring about desired outcomes... Males do not stand a chance when this happens.

Thanks to you both! I cannot wait to be writing them as well :) Next up: Fish with mustaches, the Magnum PI hypothesis...
