I tend to try to stay out of debates that don’t really deserve to even be dignified with a response, but the next time some anti-science advocate starts crowing about “Intelligent Design”, lob this fact at ’em:

Birds, animals that fly, have no sphincters.

That means that they just poop whenver the food moves through them. They can’t hold it. Even if they wanted to, they don’t have the equipment with which to “hold it”.

Their sad little cloacas just can’t do anything besides give a free pass and wave goodbye as the used food makes its way Earthward.

And these are birds. Birds that fly. In the air. Over our heads. With nothing to stop their copious waste from exiting their birdly posteriors.

Now, what was that you were saying about “Intelligent Design”?
