What is a butt? That’s what science journalist Katherine Wu wanted to know. Her quest for an answer leads her into a web of big butt questions, and a search to find the top butt scientists in the world. She discovers a debate over where butts come from, and a very strange butt that could rewrite the annals of butt history.


This episode features Katherine Wu and the story behind her amazing article. We highly recommend reading it! (It's written for adults, but we think it's kid-friendly... enough.) There's lots more brilliant butt facts to be found in it!
