Few topics are more fascinating and mysterious than the history of life on earth. We all learn about it in school and then forget a lot of what we've learned! We also discover that what we've learned becomes outdated as scientists make new discoveries.

Our guest on this episode is paleontologist and evolutionary biologist Henry Gee, who is a senior editor at the science journal, Nature. Henry is the author of several books, the latest of which is called, "A Very Short History of Life on Earth: 4.6 Billion Years in 12 Pithy Chapters".
