Summary: In this episode, we learn about a bird that basically evolved into a mammal. The sheer number of areas where they have converged with mammals is absurd. Ironically, the mammals they have almost become may be their undoing. Enjoy the show. If you have 45 seconds to spare, please nominate our show, Species, for the Podcast Awards!
