Your Inner Reptile
This film explores what our hair, teeth, and hearing reveal about our evolution from ancient reptilian ancestors.
A key moment in human evolutionary history occurred 200 million years ago, when the ferocious, reptile-like animals that roamed Earth were evolving into shrew-like mammals. But our reptilian ancestors left their mark on many parts of the human body, including our skin, teeth, and ears.
This film is the second episode in Your Inner Fish, a series that originally aired on PBS and is hosted by anatomist and paleontologist Neil Shubin. Shubin journeys to meet our ancient animal ancestors while revealing the impact those animals have had on our bodies. Due to international distribution restrictions, the series can be streamed only in the United States and Canada.
