All over the world people report sightings of big, hairy, human-like beasts, so could Bigfoot really be out there... somewhere? We ask Dr. Jeff Meldrum, Prof. Bryan Sykes, Prof. Todd Disotell, and the Round Rock, Texas, Department of Parks and Recreation.

CORRECTION: In a previous version of this podcast we said Dr Meldrum works at the University of Idaho. He actually works at Idaho State University. We've updated this episode with his correct title.
