First Steps: How Walking Upright Made Us Human

Humans are the only mammals to walk on two, rather than four, legs. From an evolutionary perspective, this is an illogical development, as it slows us down. But here we are, suggesting there must have been something tremendous to gain from bipedalism. First Steps takes our ordinary, everyday walking experience and reveals how unusual and extraordinary it truly is. The seven-million-year-long journey through the origins of upright walking shows how it was in fact a gateway to many of the other attributes that make us human—from our technological skills and sociality to our thirst for exploration. DeSilva uses early human evolution to explain the instinct that propels a crawling infant to toddle onto two feet, differences between how men and women tend to walk, physical costs of upright walking, including hernias, varicose veins and backache, and the challenges of childbirth imposed by a bipedal pelvis. And he theorises that upright walking may have laid the foundation for the traits of compassion, empathy and altruism that characterise our species today and helped us become the dominant species on this planet. In First Steps, Jeremy DeSilva brilliantly intertwines the best of anatomy, physiology, and palaeontology to present a top-notch narrative on the evolution of bipedalism. The book is a treasure trove for nature and science enthusiasts, offering a deep dive into the life sciences through the lens of primates and their journey to upright walking.
