Walking Upright

Winner of the W.W. Howells Book Prize from the American Anthropological Association and named one of the best science books of 2021 by Science News “DeSilva takes us on a brilliant, fun, and scientifically deep stroll through history, anatomy, and evolution, in order to illustrate the powerful story of how a particular mode of movement helped make us one of the most wonderful, dangerous and fascinating species on Earth.”—Agustín Fuentes, Professor of Anthropology, Princeton University and author of Why We Believe: Evolution and the Human Way of Being “Breezy popular science at its best. . . . Makes a compelling case overall.”—Science News Blending history, science, and culture, a stunning and highly engaging evolutionary story exploring how walking on two legs allowed humans to become the planet’s dominant species. Humans are the only mammals to walk on two, rather than four legs—a locomotion known as bipedalism. We strive to be upstanding citizens, honor those who stand tall and proud, and take a stand against injustices. We follow in each other’s footsteps and celebrate a child’s beginning to walk. But why, and how, exactly, did we take our first steps? And at what cost? Bipedalism has its drawbacks: giving birth is more difficult and dangerous; our running speed is much slower than other animals; and we suffer a variety of ailments, from hernias to sinus problems. In First Steps, paleoanthropologist Jeremy DeSilva explores how unusual and extraordinary this seemingly ordinary ability is. A seven-million-year journey to the very origins of the human lineage, First Steps shows how upright walking was a gateway to many of the other attributes that make us human—from our technological abilities, our thirst for exploration, our use of language–and may have laid the foundation for our species’ traits of compassion, empathy, and altruism. Moving from developmental psychology labs to ancient fossil sites throughout Africa and Eurasia, DeSilva brings to life our adventure walking on two legs. Delving deeply into the story of our past and the new discoveries rewriting our understanding of human evolution, First Steps examines how walking upright helped us rise above all over species on this planet. First Steps includes an eight-page color photo insert.

"Who said Walking Upright would be easy?" On the surface self-assured, Tyler Kensington seems to have it alla fulfilling career on the fast track, a steady relationship, and a tight-knit circle of family and friends. But, upheaval is just around the corner. Faced with reality of losing her job and her relationship, Tyler ventures into unfamiliar territory when her best friend Alex convinces her to relocate to San Diego. Her mom chides her about growing in her relationship with the Lord and her I grew up in church mantra will gradually mean less and less. Her friends, Alex and Rae, though well-meaning, are in no position to offer Tyler spiritual advice. San Diego brings a new friend and co-worker, Chrissie, an older lady who becomes like a mother figure at her new church, Yolanda, and finally meeting someone who isnt packaged to her tastewho isnt even on her menu. Tyler whines to God, This Aint What I Ordered! "Watch what unfolds as Tyler Kensington, the self-assured, "I grew up in church girl, experiences the Word growing up in her."

Science has given us several explanations for how humans evolved from walking on four limbs to two feet. None, however, is as riveting as what master storyteller Ngũgĩ wa Thiong'o offers in The Upright Revolution. Blending myth and folklore with an acute insight into the human psyche and politics, Wa Thiong'o conjures up a fantastic fable about how and why humans began to walk upright. It is a story that will appeal to children and adults alike, containing a clear and important message: "Life is connected." Originally written in Gikuyu, this short story has been translated into sixty-three languages--forty-seven of them African--making it the most translated story in the history of African literature. This new collector's edition of The Upright Revolution is richly illustrated in full color with Sunandini Banerjee's marvellous digital collages, which open up new vistas of imagination and add unique dimensions to the story.

Der Band enthält die wichtigsten Resultate der 13. Internationalen Senckenberg Konferenz, die im Oktober 1999 bei der Werner Reimers Stiftung in Bad Homburg v.d.H. sowie im Forschungsinstitut Senckenberg in Frankfurt a.M. stattfand. Behandelt werden darin die Biomechanik des aufrechten Ganges ebenso wie Konstruktions- und Funktionsanalysen rezenter und fossiler Primaten, welche in diesem Zusammenhang von Bedeutung sind. Schwergewicht liegt dabei auf der Rolle, welche die Vorderextremitäten beim aufrechten Gang und seiner Evolution spielten. Dies ist ein oft vernachlässigter Aspekt, insbesondere in Zusammenhang mit der Frage, war es Pronogradie oder Orthogradie oder was sonst, von dem die evolutive Entwicklung des aufrechten Ganges ausging? Besondere Beachtung erfährt die Analyse bedeutender Fossilfunde, insbesondere des Skelettes des 3,3 Millionen Jahre alten Australopithecus von Sterkfontein, Südafrika, wie auch der berühmten FuÃ_spuren von Laetoli, Tansania. Ein spezielles Kapitel ist dem nach wie vor rätselhaften Menschenaffen Oreopithecus gewidmet, der vor etwa 8 Millionen Jahren auf Inseln des Tyrrhenischen Meeres lebte und möglicherweise bereits zweibeinig-aufrecht ging. Als Experiment der Natur könnte dieser Fall zeigen, in welchem MaÃ_e ähnliche, wenn auch nicht identische Vorbedingungen in der Evolution zu ähnlichen, wenn auch nicht identischen Resultaten führen. Der Band schlieÃ_t mit einer kurzen Zusammenfassung und Diskussion des konstruktionsmorphologischen Ansatzes bei der Rekonstruktion der Evolution des aufrechten Ganges.

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.

Glenn Colquhoun grew up "looking over the fence" in the cultural melting pot of South Auckland, New Zealand. After working in a variety of jobs he decided to become a doctor. During his training he took a year off and lived in Te Tii, in a remote part of the Bay of Islands.

In the current resurgence of interest in the biological basis of animal behavior and social organization, the ideas and questions pursued by Charles Darwin remain fresh and insightful. This is especially true of The Descent of Man and Selection in Relation to Sex, Darwin's second most important work. This edition is a facsimile reprint of the first printing of the first edition (1871), not previously available in paperback. The work is divided into two parts. Part One marshals behavioral and morphological evidence to argue that humans evolved from other animals. Darwin shoes that human mental and emotional capacities, far from making human beings unique, are evidence of an animal origin and evolutionary development. Part Two is an extended discussion of the differences between the sexes of many species and how they arose as a result of selection. Here Darwin lays the foundation for much contemporary research by arguing that many characteristics of animals have evolved not in response to the selective pressures exerted by their physical and biological environment, but rather to confer an advantage in sexual competition. These two themes are drawn together in two final chapters on the role of sexual selection in humans. In their Introduction, Professors Bonner and May discuss the place of The Descent in its own time and relation to current work in biology and other disciplines.

This “passionate affirmation of the simple life” explores how walking has influenced history’s greatest thinkers—from Henry David Thoreau and John Muir to Gandhi and Nietzsche (Observer) “It is only ideas gained from walking that have any worth.” —Nietzsche In this French bestseller, leading thinker and philosopher Frédéric Gros charts the many different ways we get from A to B—the pilgrimage, the promenade, the protest march, the nature ramble—and reveals what they say about us. Gros draws attention to other thinkers who also saw walking as something central to their practice. On his travels he ponders Thoreau’s eager seclusion in Walden Woods; the reason Rimbaud walked in a fury, while Nerval rambled to cure his melancholy. He shows us how Rousseau walked in order to think, while Nietzsche wandered the mountainside to write. In contrast, Kant marched through his hometown every day, exactly at the same hour, to escape the compulsion of thought. Brilliant and erudite, A Philosophy of Walking is an entertaining and insightful manifesto for putting one foot in front of the other.
