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.

A Science News Best Science Book of the Year: “A brilliant, fun, and scientifically deep stroll through history, anatomy, and evolution.” —Agustín Fuentes, PhD, author of The Creative Spark: How Imagination Made Humans ExceptionalWinner of the W.W. Howells Book Prize from the American Anthropological AssociationBlending history, science, and culture, this highly engaging evolutionary story explores 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, this book shows how upright walking was a gateway to many of the other attributes that make us human—from our technological abilities to our thirst for exploration and 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.Includes photographs“A book that strides confidently across this complex terrain, laying out what we know about how walking works, who started doing it, and when.” —The New York Times Book Review“DeSilva makes a solid scientific case with an expert history of human and ape evolution.” —Kirkus Reviews“A brisk jaunt through the history of bipedalism . . . will leave readers both informed and uplifted.” —Publishers Weekly“Breezy popular science at its best.” —Science News

The award-winning author of First Steps returns with a revelatory tour of the latest scientific discoveries in archaeology and paleontology to challenge the idea of human exceptionalism, presenting a more complex—and fascinating—portrait of Us: who came before us, and what of us comes from them?As our knowledge and understanding of the past has deepened, one thing has remained constant: our belief that we humans are special. But recent scientific discoveries in the fossil record challenge this notion.Our species did not experience some magical leap forward from ape-like ancestor to sentient being, Jeremy DeSilva argues. In Us, he uses the latest fossil, genetic, and archaeological discoveries to dismantle the myth of human exceptionalism, showing how traits we prize as uniquely human—from creating art to feeling empathy—have deep roots in our extinct relatives and primate cousins. What makes us human is in fact a suite of characteristics patched together through cultural diffusion, biological evolution, and the genetic absorption of Neandertals, Denisovans, and other non-sapiens cousins into our gene pool. Some abilities we inherited; some were borrowed and refined. But very few are truly ours.Witty and compelling, Us takes us to the discovery sites of extraordinary human fossils and the scientists who are unearthing them; to molecular laboratories squeezing ancient DNA from half-a-million-year-old fossils, and atom-smashing facilities where high-powered X-rays look deep within the bones of long extinct ancestors. It reveals how they communicated, worked together, and solved problems—strategies that helped them survive and that may provide important clues for overcoming our ecological challenges.We are at a new dawn in understanding human evolution. Us brings us face-to-face with our ancestors as never before. It is a vivid, humbling, and profoundly connected view of who we are and where we come from: a new story of Us.

Leading scholars take stock of Darwin's ideas about human evolution in the light of modern scienceIn 1871, Charles Darwin published The Descent of Man, a companion to Origin of Species in which he attempted to explain human evolution, a topic he called "the highest and most interesting problem for the naturalist." A Most Interesting Problem brings together twelve world-class scholars and science communicators to investigate what Darwin got right—and what he got wrong—about the origin, history, and biological variation of humans.Edited by Jeremy DeSilva and with an introduction by acclaimed Darwin biographer Janet Browne, A Most Interesting Problem draws on the latest discoveries in fields such as genetics, paleontology, bioarchaeology, anthropology, and primatology. This compelling and accessible book tackles the very subjects Darwin explores in Descent, including the evidence for human evolution, our place in the family tree, the origins of civilization, human races, and sex differences.A Most Interesting Problem is a testament to how scientific ideas are tested and how evidence helps to structure our narratives about human origins, showing how some of Darwin's ideas have withstood more than a century of scrutiny while others have not.A Most Interesting Problem features contributions by Janet Browne, Jeremy DeSilva, Holly Dunsworth, Agustín Fuentes, Ann Gibbons, Yohannes Haile-Selassie, Brian Hare, John Hawks, Suzana Herculano-Houzel, Kristina Killgrove, Alice Roberts, and Michael J.
