Episode description
Happy Snake Week! Every episode this week explores a different question about our slithery friends. Here’s a mind blower for you: did you know the ancestors of snakes used to have legs? Somewhere along the zigzag path of evolution, they traded in their lizardy legs for a more streamlined look. But why did snakes go legless? We asked biologist and snake researcher Emily Taylor to help us find the answer.
