Summary

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. Got a question that’s snaking around your brain? Send it to us at BrainsOn.org/contact, and we’ll find a fangtastic answer! See omnystudio.com/listener for privacy information.

1:07.5	I trip over my own feet or over a bump in the sidewalk. I've tripped over logs. I've tripped over
1:13.8	dogs. One time, I got startled by a car honk and I walked straight into a street sign. So embarrassing.
1:22.3	Sometimes I think moving around would be a lot easier if I didn't have legs. I mean, snakes don't have
1:27.2	legs and they don't trip, right? mean, snakes don't have legs, and they don't
1:28.2	trip, right? Plus, even if they did fall, they're already on the ground, so it wouldn't hurt so
1:34.5	much. I know millions of years ago the ancestors of snakes had legs, so what happened? Were they as
