Hold on to your butts. This episode is about… butts. The science and evolutionary history of your rear end, the down-low on your derriere, shining a little light where the sun don't shine… you get the picture. But(t) seriously, we don't talk about this all-important hole enough, and how, from an evolutionary perspective, it might be the most important orifice on your body.
