Why we walk on two legs instead of four? Why we can see in color but have a lousy sense of smell? Your Inner Fish delves deep into the past to answer questions like these. The three-part series reveals a startling truth: Hidden within the human body is a story of life on Earth. Based on a best-selling book by evolutionary biologist Neil Shubin, this scientific adventure story takes viewers from Ethiopia to the Arctic Circle on a hunt for the many ways that our animal ancestors shaped our anatomical destiny. Shubin has spent much of his life studying our ancient ancestors----searching for the deep pedigree of Homo sapiens. Using both the fossil record and DNA evidence, he traces various parts of our body's structure to creatures that lived long, long ago. Your Inner Fish In the first episode, "Your Inner Fish," he journeys back to a time, some 375 million years ago, when the first fish crawled up onto land. Shubin's quest for the fossil record of this primeval predecessor takes viewers from highway cuts in rural Pennsylvania to the remote Arctic. After years of searching, he and his colleagues finally found a fossilized fish, known as Tiktaalik, that had enough strength in its front fins to do pushups and heave itself out of the water. Remarkably, we can trace the ancestry of our own hands and arms all the way back to these fins. Viewers also meet the scientists who discovered the DNA recipe for constructing the human hand — an essential set of instructions passed down from fish like Tiktaalik and shared today with a surprising number of other animals, from chickens to chimpanzees. Along the way, Shubin makes it clear that we can also thank our fishy past for many of our body's quirks, such as hernias. We are, every one of us, just a jury-rigged fish.
