Don’t miss our next video! SUBSCRIBE! ►► http://bit.ly/iotbs_sub The human hand, with its multi-talented thumb, might be man's greatest tool. But did you know we can trace that thumb, and the hand and arm it's connected to, all the way back to a 375 million-year-old fish named Tiktaalik? This week I sit down with paleontologist and geneticist Dr. Neil Shubin to learn what a fish, and a little blue hedgehog, can teach us about the evolution of thumbs. Be sure to watch Neil Shubin's special 3-part series "Your Inner Fish" on your local PBS station, premiering Wednesday, April 9 at 10 PM Eastern! http://www.pbs.org/your-inner-fish/home/ Also check out Neil's book "Your Inner Fish": http://amzn.to/1ssBCFt Joe Hanson - Host and writer Joe Nicolosi - Director Amanda Fox - Producer, Spotzen IncKate Eads - Associate Producer Katie Graham - Director of Photography Andrew Matthews - Editor and motion graphics John Knudsen - Gaffer Music: "Ouroboros" by Kevin MacLeod Produced for PBS Digital Studios ----------- Join us on Patreon!   / itsokaytobesmart   Twitter   / drjoehanson     / okaytobesmart   Instagram   / drjoehanson     / okaytobesmart   Merch https://store.dftba.com/collections/i...
