Dr. Neil Shubin: Finding Your Inner Fish

What do fish fossils tell us about the human body? Ancient fossils, like the Tiktaalik roseae that Dr. Shubin discovered, illustrate the transitional form between fish and land animals. They teach scientists about how our limbs came into being, among other things. But how can scientists predict where to find such transitional fossils? Dr. Shubin will take us from the anatomy laboratory to the Canadian Arctic in search of answers. For more lectures from the Carnegie Institution for Science visit: http://f4a.tv/1piEhnf
