All of our major personal problems are caused by evolution. Think about it: We crave fats and sugar because of the evolutionary advantage of seeking these high-calorie foods, we fret endlessly over sex due to the biological imperative to reproduce, and our backs hurt like hell because bipedalism evolved relatively recently (and the kinks haven't been worked out). In other words: #thanksevolution. 

We don't want to wade into the evolution "debate" by "picking sides" on this "contentious issue," so we'll just say that we are on the side of the debate that is correct. But no matter what "side" you "take," you can still express your feelings through the universal language of graphic t-shirt design.
