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.

About the Author
Jeremy DeSilva is an anthropologist at Dartmouth College. He is part of the research team that discovered and described two ancient members of the human family tree--Australopithecus sediba and Homo naledi. He has studied wild chimpanzees in Western Uganda and early human fossils in museums throughout Eastern and South Africa. From 1998 to 2003, he worked as an educator at the Boston Museum of Science. He continues to be passionate about science education and travels throughout New England, giving lectures on human evolution. He and his wife, Erin, live in Norwich, Vermont, with their twins, Ben and Josie.
"Before our ancestors thought symbolically, before they used fire, before they made stone tools, or even entered the open savanna, our ancestors walked upright. In one way or another, this odd locomotory style has underwritten the whole spectrum of our vaunted human uniquenesses, from our manual dexterity to our hairless bodies, and our large brains. In the modern world it even influences the way other people recognize us at a distance, and it is crucial to our individual viability. In this authoritative but charmingly discursive and accessible book, Jeremy DeSilva lucidly explains how and why."--Ian Tattersall, author of Masters of the Planet and The Strange Case of the Rickety Cossack
"It should come as no surprise that walking matters. But what will surprise most readers is how and why. 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
DeSilva makes a solid scientific case with an expert history of human and ape evolution . . . Accessible, valuable popular anthropology.--Kirkus Reviews
