Poopy science

"We aren't supposed to talk about it...until now! It grosses everyone out, but body waste is an essential part of being alive. From ancient civilizations using poop to wage war on their enemies to animals using their dung to send messages, feces are fascinating! In this poopy primer, we'll get to the bottom of: how your body makes waste, which animals eat poop and why, where poop went before toilets were invented, a little something called 'poop soup' (don't ask!) It's time to find out everything you never knew you wanted to know about the science of poo!"--Jacket flap.
