Neil Shubin – Your Inner Fish: A Journey into the 3.5-Billion-Year History of the Human Body

Animals all come from the sea. Spinal cords, backbones, bones themselves, our familiar trunk-and-limb anatomical structure, all evolved from fish. Even today, human embryos briefly have gills early in development, which is something to think about the next time you touch the side of your neck. Lungs and swim bladders are evolutionary cousins, and fish could not have made the move to land without them. Eyes first developed back in our seafaring days, and our lenses are still better adapted to seeing through water than air. As distant and diverse as life can be on Earth, we have more in common than we think. Shubin makes that point as well as anyone, sometimes in amusing fashion.
