The oldest natural history museum in North America, the Academy of Natural Sciences, is near where Gavin lives, in Philadelphia, Pennsylvania! Some students from Gavin's university took a trip to the Academy for a class this semester, and Gavin tagged along to meet Dr. Ted Daeschler. Dr. Daeschler works on the evolutionary transitions from fish with fins, to land-dwelling animals with limbs, and he was nice enough to join us this episode for an interview!
