Atheists: Do you like to release the beast in you?

According to Darwinism, which you ardently believe in, we are all descended from synapsid reptiles like the fearsome Dimetrodon. In fact, the evolutionists would contend that we are just modified variants of such hideous creatures. So, atheists, do you feel very monstrous and beastly? Do you often growl at night and roar during the day because that is just part of living your evolutionary ancestry?
