Episode Title: When Trees Took Over the World

Air Date: 2021-05-12

Overview:

420 million years ago, the forest floor of what's now New York was covered with a plant that didn’t look like a tree at all, except its roots were made of wood. Instead of looking up to learn about the evolution of trees, it turns out paleobotanists should’ve been looking down all along.
