Podcast 12 - "All" its "Descendents"

In this episode, we discuss two studies that try to piece apart the effects that the ecological niche breadth (i.e. the range of habitats an animal can survive in) of an animal has on its potential to diversify and/or survive over long periods of time. Also, Hell freezes over as James manages to come up with a perfect reference to the band "The Descendents".
