Your Inner Fish

Premiered April 2014

How did your body become the complicated, quirky, amazing machine it is today? Anatomist Neil Shubin uncovers the answers in this new look at human evolution. Using fossils, embryos and genes, he reveals how our bodies are the legacy of ancient fish, reptiles and primates — the ancestors you never knew were in your family tree. The three-part series premiered April 9, 2014.
