Hair

Mammals pretty much have the market cornered on hair, and you know all the other types of animals are jealous of us. Imagine a little lizard with bangs or something? It just wouldn’t be right. Sorry!

Follow us on Twitter @SciShowTangents, where we’ll tweet out topics for upcoming episodes and you can ask the science couch questions!
