Your Inner Fish

Have you ever wondered why the human body looks the way it does? Why our hands have five fingers instead of six? Why we walk on two legs instead of four? It took more than 350 million years for the human body to take shape. How did it become the complicated, quirky, amazing machine it is today? Your Inner Fish delves deep into the past to answer these questions. 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. Premiering Wednesday, April 9, 2014, the three-part series reveals a startling truth: Hidden within the human body is a story of life on Earth.
