Restless creatures

Most of us never think about how we get from one place to another. For most people, putting one foot in front of the other requires no thought at all. Yet the fact that we and other species are able to do so is one of the great triumphs of evolution. To truly understand how life evolved on Earth, it is crucial to understand movement. This is a bold new argument that the true story of evolution is the story of locomotion, from the first stirrings of bacteria to the amazing feats of Olympic athletes.
