Young readers will learn how a British naturalist named Charles Darwin studied nature and developed his now-famous concepts of natural selection and survival of the fittest. And how modern-day science has added to our understanding of the theory of evolution. Can something as complex and wondrous as the natural world be explained by a simple theory? The answer is yes, and now Evolution explains how in a way that makes it easy to understand.

    Virtually unknown to archaeologists until the early twentieth century, their true importance is only now being realized and shedding new light on how the Indian peoples of the Americas came to be here.

    But in the full history of life, ancient animals, even the trilobites, form only the half-billion-year tip of a nearly four-billion-year iceberg. Andrew Knoll explores the deep history of life from its origins on a young planet to the incredible Cambrian explosion, presenting a compelling new explanation for the emergence of biological novelty. The very latest discoveries in paleontology--many of them made by the author and his students--are integrated with emerging insights from molecular biology and earth system science to forge a broad understanding of how the biological diversity that surrounds us came to be. Moving from Siberia to Namibia to the Bahamas, Knoll shows how life and environment have evolved together through Earth's history. Innovations in biology have helped shape our air and oceans, and, just as surely, environmental change has influenced the course of evolution, repeatedly closing off opportunities for some species while opening avenues for others. Readers go into the field to confront fossils, enter the lab to discern the inner workings of cells, and alight on Mars to ask how our terrestrial experience can guide exploration for life beyond our planet. Along the way, Knoll brings us up-to-date on some of science's hottest questions, from the oldest fossils and claims of life beyond the Earth to the hypothesis of global glaciation and Knoll's own unifying concept of ''permissive ecology.'' In laying bare Earth's deepest biological roots, Life on a Young Planet helps us understand our own place in the universe--and our responsibility as stewards of a world four billion years in the making.In a new preface, Knoll describes how the field has broadened and deepened in the decade since the book's original publication.

    In his groundbreaking Before the Dawn, Wade reveals humanity's origins as never before--a journey made possible only recently by genetic science, whose incredible findings have answered such questions as: What was the first human language like? How large were the first societies, and how warlike were they? When did our ancestors first leave Africa, and by what route did they leave? By eloquently solving these and numerous other mysteries, Wade offers nothing less than a uniquely complete retelling of a story that began 500 centuries ago.

    In fact, five of them could fit into the period at the end of this sentence.On a clear, warm Sunday, April 14, 1935, a wild wind whipped up millions upon millions of these specks of dust to form a duster—a savage storm—on America's high southern plains.The sky turned black, sand-filled winds scoured the paint off houses and cars, trains derailed, and electricity coursed through the air. Sand and dirt fell like snow—people got lost in the gloom and suffocated . . . and that was just the beginning.Don Brown brings the Dirty Thirties to life with kinetic, highly saturated, and lively artwork in this graphic novel of one of America's most catastrophic natural events: the Dust Bowl.

    Now, using advanced imaging technology, scientists have solved the mystery of its intricate workings. Unmatched in complexity for a thousand years, the mechanism functioned as the world's first analog computer, calculating the movements of the sun, moon, and planets through the zodiac. In Decoding the Heavens, Jo Marchant details for the first time the hundred-year quest to decode this ancient computer. Along the way she unearths a diverse cast of remarkable characters--ranging from Archimedes to Jacques Cousteau--and explores the deep roots of modern technology, not only in ancient Greece, but in the Islamic world and medieval Europe. At its heart, this is an epic adventure story, a book that challenges our assumptions about technology development through the ages while giving us fresh insights into history itself.

    And despite his father's efforts to turn young Darwin — a poor student — into a doctor or clergyman, the born naturalist jumped instead at the chance to sail around South America, observing and collecting flora and fauna all the way. In a clear, engaging narration, Kathryn Lasky takes readers along on Darwin's journey, from his discovery of seashells on mountaintops that revealed geological changes to his observations of variations in plants and animals, suggesting that all living things are evolving over time. Matthew Trueman's striking mixed-media illustrations include actual objects found in nature, enhancing this compelling look at the man behind the bold theory that would change the way we think about the world — and ourselves.

    She landed in the New World and lived there for three years, giving birth to a baby before sailing home. Or so the Icelandic sagas say. Even after archaeologists found a Viking longhouse in Newfoundland, no one believed that the details of Gudrid’s story were true. Then, in 2001, a team of scientists discovered what may have been this pioneering woman’s last house, buried under a hay field in Iceland, just where the sagas suggested it could be. Joining scientists experimenting with cutting-edge technology and the latest archaeological techniques, and tracing Gudrid’s steps on land and in the sagas, Nancy Marie Brown reconstructs a life that spanned—and expanded—the bounds of the then-known world. She also sheds new light on the society that gave rise to a woman even more extraordinary than legend has painted her and illuminates the reasons for its collapse.
