Have you ever seen animals today, like certain birds or reptiles, that sort of look... prehistoric? It turns out that once evolution finds a trick that works, it tends to repeat it. Join Hank for a new episode of SciShow and learn about a few prehistoric animals that look a lot like ones we know today!

SciShow has a spinoff podcast! It's called SciShow Tangents. Check it out at http://www.scishowtangents.org
