Mo welcomes his friend Michael Ian Black – comedian, author, podcaster, and, as it turns out, Neanderthal (we’ll explain). Mo talks to Michael and the world’s leading researchers about why our extinct human cousins Neanderthals have gotten such a bad rap for so many many years, and how we’re learning more about how close we really were. Oh, Mo also talks to the guy who played Cha-ka on the 70s kids show Land of the Lost.
