Bum, butt, behind, whatever you call it, the one you're sitting on right now is the finely tuned result of millions of years of evolution. Fascinating, isn't it?

Now, don't be alarmed, but your bum holds a story as old as time itself. From cave-people to present day, evolution has shaped this essential body part in remarkable ways. It's more than just a place to sit--it's a marvel of adaptation and survival! The humble bum has been created by millions of years of evolution, so surely, it's time to learn all about it...

Join the Crab Museum and illustrator Inga Ziemele for a hilarious kids' guide to evolution and the natural history of this noble body part. Get up close and personal with big bums, small bums, stinky bums, glow-in-the-dark bums, jet-engine bums, fossilized bums, and even an animal with 1,000 bums! Along the way, discover the surprising uses animals have found for their bums, and even witness a terrible time in Earth's history when there were no bums at all.

With A Natural History of Bums, you can finally learn the answer to that most important of questions: who has the biggest bum in the world? So, are you sitting comfortably? Yes, you are--because of your bum!
