Ep. 24 - The Flying* Squirrel

*it doesn't actually fly.

Steve and Bill wrap up 2017 with an episode about Flying Squirrels. They talk about their adaptations for gliding, evolutionary history, and baculum morphology. They also talk about the new species that was discovered earlier this year. Enjoy!

This episode was recorded with new lapel mics that the guys tried out for the first time. We hope the audio quality was better (but we're still working on it). Thank you to all our patrons and especially Dan Stapleton, Amanda Hicks, and Julie Davies for their generous paypal donations.

@23:30 Steve says "geological," but he meant "geographical"
@27:30 Steve says "the forest grows in the soil," but he meant to say "the fungi grows in the soil"
@33:55 Steve says "all extant flying squirrels," but he should have just said "all flying squirrels"\
