““Put your imagination hat on, because we are going back to prehistoric times. I don't know if you are a dude, a chick, or somewhere outside the binary, but for simplicity’s sake, let's pretend that you are a caveman. You’ve got yourself a nice little cave with some sick stick figure paintings and a partner who can light a mean fire with some twigs and stuff. Well one day you are out in the plains looking for some food or doing whatever the hell you cavemen do all day and you decide to drop back by the crib to rest for a bit. You roll up to the cave and notice some other dude's loincloth outside. Aw, hell no. You peek your head in and see that asshole Grock from down the street about to make your mate reproductively unavailable for 9 months. Are you just gonna take that? No way, man. Evolution's got your back.””
