The paleoanthropologist Jeremy DeSilva journeys to Africa to discover how early hominids first walked on two legs, before investigating the evolutionary advantages this gave them, including the ability to use tools and weapons and, by freeing the chest muscles, to speak. He also explains how we still live with the disadvantages, including back pain and hip and knee problems.\nABOUT US\nDELIVERY RETURNS\nPostscript is a long-established mail order company specialising in good quality publishers' overstocks and remainder books at discounts of up to 80% off the published price.
