Long Description: 
A key moment in our evolutionary saga occurred 200 million years ago, when the ferocious reptile-like animals that roamed the Earth were in the process of 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.
