Todd Akin has been back-peddling on his statement that “legitimate rape” cannot lead to pregnancy. Of course, we all know that’s ridiculous. But what a human-centric way of thinking we have.

And… Oh why am I trying to explain this? Take it away, Isabella!
Here’s a link to a Scientific American story that says some species of females (animal and human) might ovulate in response to a protein in male semen.
