Why does the human body look the way it does? Why do we walk on two legs instead of four?

It took more than hundreds of millions of years for the human body to take shape, and the new three-part series "Your Inner Fish," premiering Wednesdays, April 9-23 explores the science of how the human body became the complicated, quirky, amazing machine it is today.

Hosted by leading paleobiologist Dr. Neil Shubin and based on his best-selling book of the same name. Taking viewers on a cutting-edge scientific adventure, "Your Inner Fish" reveals a startling truth: Hidden within the human body is a history of life on Earth.

In the first episode, Neil Shubin explores how our arms, legs, necks and lungs were bequeathed to us by a fish that lumbered onto land some 375 million years ago. The genetic legacy of this creature can be seen today in our own DNA, including the genes used to build the quintessentially human feature, our hands.
