In this episode, the gang discusses two papers that try and piece apart the complicated evolutionary history of cyclostomes (lampreys and hagfish) and spiders. What did the ancestors of these things look like? Also, Amanda comes up with a lucrative business proposal, James hijacks the podcast to make a bold statement, and Curt is skeptical of history.
