Halibutboy is excited to learn that humans have a lot of things in common with fish! By understanding the anatomy of older and simpler animals we can see the raw materials that evolution had to work with to make humans. Fish paleontologist Neil Shubin shows us scientists at work, including a visit back to the site of his great 2004 discovery: Tiktaalik, a walking fish or "fishapod".

Cool. The PBS website for the show is also excellent: http://www.pbs.org/your-inner-fish/home/
