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 Exceptional Winner of the W.W. Howells Book Prize from the American Anthropological Association Blending 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 inspiring story of four-year-old Sarah Roberts, the first African American girl to try to integrate a white school, and how her experience in 1847 set greater change in motion. Junior Library Guild Selection 2017 Orbis Pictus Honor Book Chicago Public LibraryKids Best of the Best Book 2016 A Nerdy Book Club Best Nonfiction Book of 2016 An NCSS Notable Social Studies Trade Book of 2017 In 1847, a young African American girl named Sarah Roberts was attending a school in Boston. Then one day she was told she could never come back. She didn't belong. The Otis School was for white children only. Sarah deserved an equal education, and the Roberts family fought for change. They made history. Roberts v. City of Boston was the first case challenging our legal system to outlaw segregated schools. It was the first time an African American lawyer argued in a supreme court. These first steps set in motion changes that ultimately led to equality under the law in the United States. Sarah's cause was won when people--black and white--stood together and said, No more. Now, right now, it is time for change! With gorgeous art from award-winning illustrator E. B. Lewis, The First Step is an inspiring look at the first lawsuit to demand desegregation--long before the American Civil Rights movement, even before the Civil War. Backmatter includes: integration timeline, bios on key people in the book, list of resources, and author's note.

"It's a big, big world It's easy to get lost in it..." —Justin Bieber, "Up" I love those lines in the lyrics. Sometimes I feel like that's what everyone's expecting. My world got very big, very fast, and a lot of people expect me to get lost in it. I grew up in a small town in Canada. I taught myself to sing in front of my bedroom mirror and to play guitar on a hand-me-down. My mom posted my first videos on YouTube. Never in my wildest dreams did I think that I'd sell millions of records, sing for the president of the United States and sell out a massive arena tour. So no, I'm not lost. Not at all. If anything, onstage in front of my fans, I'm home. I'm found. And that's what this book is about: my journey, from singing and busking on the sidewalk in Stratford, Ontario, to performing and showing my appreciation to millions of fans all over the world for making this dream a reality. My music and lyrics give a glimpse of what's in my heart, but I think this book is a window into my world. In here are hundreds of pictures of me that no one's ever seen before, and I'll tell you about who I was before I joined forces with Scooter Braun and Usher and got a record deal, and who I've become since I've been blessed with the opportunity to share my music with the world. This is my gift to you, the fans who've supported and been with me on this amazing journey every step of the way.
