Nature cover 18 November 2004Today's craze for marathons may be a relic of two million years of intense selection. For years the study of the evolution of human locomotion has focused on bipedal walking. Running was largely ignored as humans are thought slow and inefficient. But now Dennis Bramble and Daniel Lieberman use data on comparative physiology, performance and anatomy to argue that we are in fact supremely adapted endurance runners. This ability stems from an array of structural specializations, many of them skeletal, and the fossil record suggests that the genus Homo has undergone strong selection for endurance running. So don't ask whether australopithecines walked like us: if we walk differently it may be because we run. Cover by Justin Libby, Mathieu Baissac & Daniel Lieberman, after Muybridge's nineteenth-century studies.
