In this episode, the gang looks at a few cases of fossil pathologies in arthropods, birds, and amphibians and discusses the interesting broader evolutionary ramifications of these studies. Meanwhile, Amanda wrangles cats, and Curt confuses everyone by consistently assigning taxa to the wrong groups (for example: loriciferans are not priapulids, even though they are closely related). Oh... and James leads a legitimate discussion on science ethics.
