Today, more than sixty years later, members of a new generation of scientists are attempting to create life from the ground up. Science has moved forward in leaps and bounds since Schrodinger's time, but our understanding of what does and does not constitute life has only grown more complex. An era that has already seen computer chip-implanted human brains, genetically engineered organisms, genetically modified foods, cloned mammals, and brain-dead humans kept alive by machines is one that demands fresh thinking about the concept of life. While a segment of our national debate remains stubbornly mired in moral quandaries over abortion, euthanasia, and other right to life issues, the science writer Ed Regis demonstrates how science can and does provide us with a detailed understanding of the nature of life. Written in a lively and accessible style, and synthesizing a wide range of contemporary research, What Is Life? is a brief and illuminating contribution to an age-old debate.

    Making big ideas simple, Dean takes readers on a journey to uncover what makes a dinosaur a dinosaur, what dinosaurs ate, how they evolved, what caused them to go extinct, and more!Perfect for anyone fascinated by the dinosaur exhibits at museums, palaeontology and fans of Jurassic Park.

    Williams any rock used as building material can tell a fascinating story. All he has to do is look at building stone in any urban center to find a range of rocks equal to any assembled by plate tectonics. In Stories in Stone, he takes you on his explorations to find 3.5-billion-year-old rock that looks like swirled pink and black taffy, a gas station made of petrified wood, and a Florida fort that has withstood 300 years of attacks and hurricanes, despite being made of a stone that has the consistency of a granola bar.In Stories in Stone, Williams also weaves in the cultural history of stone. He shows why a white, fossil-rich limestone from Indiana became the only building stone to be used in all 50 states; how in 1825, the construction of the Bunker Hill Monument led to America's first commercial railroad; and why when the same kind of marble used by Michelangelo was used on a Chicago skyscraper it warped so much after 19 years that all 44,000 panels of the stone had to be replaced. A love letter to building stone, from New England brownstone and Morton Gneiss of Minnsota to the limestone of Salem, Indiana; from granite and travertine to Carrara marble, David Willilams brings to life the stones you will see in the structures of every city, large and small. After reading his book, you will forever look at stone buildings with new eyes.

    Focusing on four specific examples — corn, silkworms, domestic cats, and apples — she traces the histories of species that have been fundamentally altered over the centuries by the whims and needs of people.

    Rich illustrations, systematic resumes, and extensive citations make it a valuable references source.

    But how has the earth itself determined our destiny? Our planet wobbles, driving changes in climate that forced the transition from nomadism to farming. Mountainous terrain led to the development of democracy in Greece. Atmospheric circulation patterns later on shaped the progression of global exploration, colonization, and trade. Even today, voting behavior in the south-east United States ultimately follows the underlying pattern of 75 million-year-old sediments from an ancient sea. Everywhere is the deep imprint of the planetary on the human.From the cultivation of the first crops to the founding of modern states, Origins reveals the breathtaking impact of the earth beneath our feet on the shape of our human civilizations.

    The story starts in earnest 3.8 billion years ago, with the earliest-known form of life on Earth, a bacteria that still exists today, and journeys through action-packed millennia, charting the appearance of new life forms as well as devastating extinction events. Of course, the ever-popular and endlessly intriguing dinosaurs feature large, but Prehistoric Life gives you the whole picture, and the plants, invertebrates, amphibians, birds, reptiles, and mammals that are the ancestors of today's species also populate its pages, making this book unprecedented in its coverage of prehistory. Specially commissioned artworks use cutting-edge technology to render species in breathtakingly realistic fashion, with astonishing images of prehistoric remains, such as skeletons and fossils, to complete the story. To put all the evidence in context, the concept of geological time is explored, as is the classification of species and how the evidence for their evolution is preserved and can be deciphered.New technologies have brought new life to inanimate fossils. CT scanning, for example, unlocks a 3D image of a plant or animal from a piece of rock, which can then be viewed from all angles revealing never-before-seen details. From this researchers can fill in missing pieces and even simulate how an animal might have moved. Panels explore these and numerous other scientific techniques for recovering, dating, and reconstructing, as well as profiling individuals, key excavations and discoveries, and some of the unique anatomical features that nature has developed over the course of time.The last section of the book looks at the development of humans and the eventual rise to dominance of Homo sapiens, exploring not only their changing anatomy as revealed by the fossils but also the evidence for culture and society as evidenced by extraordinary cave paintings and intricately worked tools.In combination, the stunning visuals, captivating, authoritative text, and comprehensive approach make Prehistoric Life a fascinating and revealing encyclopedia that will appeal to the whole family.TABLE OF CONTENTS1.

    Pairing Charles Darwin and a rare species of barnacle as her unlikely protagonists, Rebecca Stott has written an absorbing work of history that guides readers through the treacherous shoals of nineteenth-century biology. Beginning her scientific detective story in the 1820s, even before Darwin's Beagle voyage, Stott examines the mystery of why Darwin waited over two decades between formulating his pivotal theory of natural selection and publishing it. Lavishly illustrated, filled with riddles and concepts that challenge our notion of Victorian science, Darwin and the Barnacle is a thrilling account of how genius proceeds through indirection—and how one small item of curiosity contributed to history's most spectacular scientific breakthrough.

    Shows how our concept of humankind has changed over time and argues our current understanding of what it means to be human has been shaken by new discoveries from science and philosophy.

     It was an ancient puzzle that stymied history's greatest minds: How did the fossils of seashells find their way far inland, sometimes high up into the mountains? Fossils only made sense in a world old enough to form them, and in the seventeenth century, few people could imagine such a thing. Texts no less authoritative than the Old Testament laid out very clearly the timescale of Earth's past; in fact one Anglican archbishop went so far as to calculate the exact date of Creation...October 23, 4004, B.C. A revolution was in the making, however, and it was started by the brilliant and enigmatic Nicholas Steno, the man whom Stephen Jay Gould called "the founder of geology." Steno explored beyond the pages of the Bible, looking directly at the clues left in the layers of the Earth. With his groundbreaking answer to the fossil question, Steno would not only confound the religious and scientific thinking of his own time, he would set the stage for the modern science that came after him. He would open the door to the concept of "deep time," which imagined a world with a history of millions or billions of years. And at the very moment his expansive new ideas began to unravel the Bible's authoritative claim as to the age of the Earth, Steno would enter the priesthood and rise to become a bishop, ultimately becoming venerated as a saint and beatified by the Catholic Church in 1988. Combining a thrilling scientific investigation with world-altering history and the portrait of an extraordinary genius, "The Seashell on the Mountaintop" gives us new insight into the very old planet on which we live, revealing how we learned to read the story told to us by the Earth itself, written in rock and stone.

    The new edition maintains the scope and expertise that made the book so popular while incorporating the latest research and updating the exquisite program of drawings.

    She reveals them to be curious, clever connoisseurs of their world, technologically inventive and ecologically adaptable. Above all, they were successful survivors for more than 300,000 years, during times of massive climatic upheaval.At a time when our species has never faced greater threats, we’re obsessed with what makes us special. But, much of what defines us was also in Neanderthals, and their DNA is still inside us. Planning, co-operation, altruism, craftsmanship, aesthetic sense, imagination... perhaps even a desire for transcendence beyond mortality.It is only by understanding them, that we can truly understand ourselves.

    It produced a cloud of roiling debris that blackened the sky for months as well as other geologic disasters--and triggered the demise of Tyrannosaurus rex. We know what happened largely because Walter Alvarez--synthesizing the findings of experts from a variety of scientific fields--has written a gripping story of the decades-long search for the cause of the dinosaurs' extinction. Painstakingly assembling clues from the Italian Apennines and the depths of the Pacific and presenting them with the excitement of a great novel, T. rex and the Crater of Doom is a book of undeniable importance and irresistible appeal by a major figure in contemporary science. " Engaging and witty. Read Alvarez for and excellent account of how scientists pose questions and seek to solve them." --Scientific American " First-rate...Alvarez provides the up-close tale of the comet or asteroid that wiped out the dinosaurs." --San Francisco Chronicle

    We find animals and plants where we do because, over time, the continents have moved, separating and uniting in a long, slow dance; because sea levels have risen, cutting off one bit of land from another; because new and barren volcanic islands have risen up from the sea; and because animals and plants vary greatly in their ability to travel, and separation causes the formation of new species. This is the story of how life has responded to, and has in turn altered, the ever-changing Earth. And it includes many fascinating tales--of pygmy mammoths and elephant birds and of radical ideas by bold young scientists.
