So, have you spend all day looking for a comic that integrates Red Queen evolutionary dynamics, commentary on the application of parsimony arguments in biology, and Newt Gingrich's recent flip-flopping on Libya? No? Well, hopefully you'll enjoy this anyway. For a more viewable image, see the original at Darwin Eats Cake.
