"Before our ancestors thought symbolically, before they used fire, before they made stone tools, or even entered the open savanna, our ancestors walked upright. In one way or another, this odd locomotory style has underwritten the whole spectrum of our vaunted human uniquenesses, from our manual dexterity to our hairless bodies, and our large brains. In the modern world it even influences the way other people recognise us at a distance, and it is crucial to our individual viability. In this authoritative but charmingly discursive and accessible book, Jeremy DeSilva lucidly explains how and why." (Ian Tattersall, author of Masters of the Planet and The Strange Case of the Rickety Cossack)

"Master anatomist and paleontologist Jeremy DeSilva makes no bones about the fact that when looking at fossils 'I let myself be emotional...'. Thus does this world expert and gifted story teller take us on a tour through the sprawling, complicated, saga of human origins. Drawing on his personal knowledge of topics ranging from sports medicine to childcare and his acquaintance with a host of colourful characters - whether lying inert in museum drawer, sitting behind microscopes or feuding with one other - DeSilva adds flesh and projects feelings onto the bones he studies, a tour de force of empathic understanding." (Sarah Blaffer Hrdy, author of Mother Nature and Mothers and Others: The Evolutionary Origins of Mutual Understanding)

"A book that strides confidently across complex terrain, laying out what we know about how walking works, who started doing it and when.... DeSilva is a genial companion on this stroll through the deep origins of walking.... Illuminating." (New York Times)
