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.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eFirst 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.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eDeSilva 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.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eEach book order from the Naturalist's Guild comes included with:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eYour chosen book\u003c\/li\u003e\n\u003cli\u003eA Yorkshire Tea bag\u003c\/li\u003e\n\u003cli\u003eA Natural history themed bookmark\u003c\/li\u003e\n\u003cli\u003eA Sticky backed book plate to write your name in the inside cover of the book\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"The Naturalist's Guild","offers":[{"title":"Default Title","offer_id":56726738895223,"sku":null,"price":19.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0775\/2663\/0692\/files\/First_Steps_Non-Fiction_Book_The_Naturalist_s_Guild_1.jpg?v=1771006406","url":"https:\/\/thenaturalistsguild.com\/products\/first-steps-how-walking-upright-made-us-human-by-jeremy-desilva","provider":"The Naturalist's Guild","version":"1.0","type":"link"}
