These great beasts, or “megafauna,” lived on every habitable continent and on many islands. With a handful of exceptions, all are now gone.What caused the disappearance of these prehistoric behemoths? No one event can be pinpointed as a specific cause, but several factors may have played a role. Paleomammalogist Ross D. E. MacPhee explores them all, examining the leading extinction theories, weighing the evidence, and presenting his own conclusions. He shows how theories of human overhunting and catastrophic climate change fail to account for critical features of these extinctions, and how new thinking is needed to elucidate these mysterious losses.Along the way, we learn how time is determined in earth history; how DNA is used to explain the genomics and phylogenetic history of megafauna—and how synthetic biology and genetic engineering may be able to reintroduce these giants of the past. Until then, gorgeous four-color illustrations by Peter Schouten re-create these megabeasts here in vivid detail.

    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

    Here Dr. Lewis-Williams and David Pearce examine the intricate web of belief, myth, and society in the succeeding Neolithic period, arguably the most significant turning point in all human history, when agriculture became a way of life and the fractious society that we know today was born.The authors focus on two contrasting times and places: the beginnings in the Near East, with its mud-brick and stone houses each piled on top of the ruins of another, and western Europe, with its massive stone monuments more ancient than the Egyptian pyramids.They argue that neurological patterns hardwired into the brain help explain the art and society that Neolithic people produced. Drawing on the latest research, the authors skillfully link material on human consciousness, imagery, and religious concepts to propose provocative new theories about the causes of an ancient revolution in cosmology and the origins of social complexity. In doing so they create a fascinating neurological bridge to the mysterious thought-lives of the past and reveal the essence of a momentous period in human history. 100 illustrations, 20 in color.

    For more than a millennium, Polynesians have occupied the remotest islands in the Pacific Ocean, a vast triangle stretching from Hawaii to New Zealand to Easter Island. Until the arrival of European explorers they were the only people to have ever lived there. Both the most closely related and the most widely dispersed people in the world before the era of mass migration, Polynesians can trace their roots to a group of epic voyagers who ventured out into the unknown in one of the greatest adventures in human history.How did the earliest Polynesians find and colonize these far-flung islands? How did a people without writing or metal tools conquer the largest ocean in the world? This conundrum, which came to be known as the Problem of Polynesian Origins, emerged in the eighteenth century as one of the great geographical mysteries of mankind.For Christina Thompson, this mystery is personal: her Maori husband and their sons descend directly from these ancient navigators. In Sea People, Thompson explores the fascinating story of these ancestors, as well as those of the many sailors, linguists, archaeologists, folklorists, biologists, and geographers who have puzzled over this history for three hundred years. A masterful mix of history, geography, anthropology, and the science of navigation, Sea People combines the thrill of exploration with the drama of discovery in a vivid tour of one of the most captivating regions in the world.Sea People includes an 8-page photo insert, illustrations throughout, and 2 endpaper maps.

    Random genetic mutation, long believed to be the main source of variation, is only a marginal factor. As the authors demonstrate in this book, the more important source of speciation, by far, is the acquisition of new genomes by symbiotic merger. The result of thirty years of delving into a vast, mostly arcane literature, this is the first book to go beyond -- and reveal the severe limitations of -- the "Modern Synthesis" that has dominated evolutionary biology for almost three generations. Lynn Margulis, whom E. O. Wilson called "one of the most successful synthetic thinkers in modern biology," and her co-author Dorion Sagan have written a comprehensive and scientifically supported presentation of a theory that directly challenges the assumptions we hold about the variety of the living world.

    In this updated edition of the classic work, Mark Pendergrast reviews the dramatic changes in coffee culture over the past decade, from the disastrous “Coffee Crisis” that caused global prices to plummet to the rise of the Fair Trade movement and the “third-wave” of quality-obsessed coffee connoisseurs. As the scope of coffee culture continues to expand, Uncommon Grounds remains more than ever a brilliantly entertaining guide to the currents of one of the world’s favorite beverages.

    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. 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.

    The Human Genome Project finished sequencing human DNA. It seemed it was only a matter of time until we had all the answers to the secrets of life on this planet. The cutting-edge of biology, however, is telling us that we still don't even know all of the questions. How is it that, despite each cell in your body carrying exactly the same DNA, you don't have teeth growing out of your eyeballs or toenails on your liver? How is it that identical twins share exactly the same DNA and yet can exhibit dramatic differences in the way that they live and grow? It turns out that cells read the genetic code in DNA more like a script to be interpreted than a mould that replicates the same result each time. This is epigenetics and it's the fastest-moving field in biology today. The Epigenetics Revolution traces the thrilling path this discipline has taken over the last twenty years. Biologist Nessa Carey deftly explains such diverse phenomena as how queen bees and ants control their colonies, why tortoiseshell cats are always female, why some plants need a period of cold before they can flower, why we age, develop disease and become addicted to drugs, and much more. Most excitingly, Carey reveals the amazing possibilities for humankind that epigenetics offers for us all - and in the surprisingly near future.

    He demonstrates the critical role of maritime trade to the civilizations of ancient Egypt, Mesopotamia, and the Indus Valley. He reacquaints us with the great seafaring cultures of antiquity like those of the Phoenicians and Greeks, as well as those of India and Southeast and East Asia, who parlayed their navigational skills, shipbuilding techniques, and commercial acumen to establish thriving overseas colonies and trade routes in the centuries leading up to the age of European expansion. And finally, his narrative traces how commercial shipping and naval warfare brought about the enormous demographic, cultural, and political changes that have globalized the world throughout the post–Cold War era. This tremendously readable intellectual adventure shows us the world in a new light, in which the sea reigns supreme. We find out how a once-enslaved East African king brought Islam to his people, what the American “sail-around territories” were, and what the Song Dynasty did with twenty-wheel, human-powered paddleboats with twenty paddle wheels and up to three hundred crew. Above all, Paine makes clear how the rise and fall of civilizations can be linked to the sea. An accomplishment of both great sweep and illuminating detail, The Sea and Civilization is a stunning work of history.

    From this new form of care came new ways of engaging and understanding each other. How such singular human capacities evolved, and how they have kept us alive for thousands of generations, is the mystery revealed in this bold and wide-ranging new vision of human emotional evolution."Mothers and Others" finds the key in the primatologically unique length of human childhood. If the young were to survive in a world of scarce food, they needed to be cared for, not only by their mothers but also by siblings, aunts, fathers, friends--and, with any luck, grandmothers. Out of this complicated and contingent form of childrearing, Sarah Hrdy argues, came the human capacity for understanding others. Mothers and others teach us who will care, and who will not.From its opening vision of "apes on a plane"; to descriptions of baby care among marmosets, chimpanzees, wolves, and lions; to explanations about why men in hunter-gatherer societies hunt together, "Mothers and Others" is compellingly readable. But it is also an intricately knit argument that ever since the Pleistocene, it has taken a village to raise children--and how that gave our ancient ancestors the first push on the path toward becoming emotionally modern human beings.

    Two of the three-Nicolaus Copernicus and Charles Darwin-are widely known and heralded for their breakthroughs. The third, James Hutton, never received the same recognition, yet he profoundly changed our understanding of the earth and its dynamic forces. Hutton proved that the earth was likely millions of years old rather than the biblically determined six thousand, and that it was continuously being shaped and re-shaped by myriad everyday forces rather than one cataclysmic event. In this expertly crafted narrative, Jack Repcheck tells the remarkable story of this Scottish gentleman farmer and how his simple observations on his small tract of land led him to a theory that was in direct confrontation with the Bible and that also provided the scientific proof that would spark Darwin's theory of evolution. It is also the story of Scotland and the Scottish Enlightenment, which brought together some of the greatest thinkers of the age, from David Hume and Adam Smith to James Watt and Erasmus Darwin. Finally, it is a story about the power of the written word. Repcheck argues that Hutton's work was lost to history because he could not describe his findings in graceful and readable prose. (Unlike Darwin's Origin of the Species, Hutton's one and only book was impenetrable.) A marvelous narrative about a little-known man and the science he founded, The Man Who Found Time is also a parable about the power of books to shape the history of ideas.

    In Temples, Tombs, and Hieroglyphs, Dr. Mertz explores the breathtaking reality behind her fiction by casting a dazzling light on a remarkable civilization that, even after thousands of years, still stirs the human imagination and inspires awe with its marvelous mysteries and amazing accomplishments.A fascinating chronicle of an extraordinary epoch—from the first Stone Age settlements through the reign of Cleopatra and the Roman invasions—Temples, Tombs, and Hieroglyphs brings ancient Egypt to life as never before. Lavishly illustrated with pictures, maps, photographs, and charts, it offers tantalizing glimpses into Egyptian society and everyday life; amazing stories of the pharaohs and the rise and fall of great dynasties; religion and culture; folklore and fairy tales; stories of the explorers, scientists, and unmitigated scoundrels who sought to unravel or exploit the ageless mysteries; and breathtaking insights into the magnificent architectural wonders that rose up from the desert sands.Revised and updated to include the results of the most recent historical research and archaeological finds, Dr. Mertz's book is unhampered by stuffy prose and dry academic formality. Instead, it is a vibrant, colorful, and fun excursion for anyone who's ever fantasized about exploring the Valley of the Kings, viewing up close the treasures of the temple of Queen Hatshepsut, or sailing down the Nile on Cleopatra's royal barge.

    But the theory of evolution did not spring full-blown from the head of Darwin. Since the dawn of humanity, priests, philosophers, and scientists have debated the origin and development of life on earth, and with modern science, that debate shifted into high gear.In this lively, deeply erudite work, Pulitzer Prize–winning science historian Edward J. Larson takes us on a guided tour of Darwin’s “dangerous idea,” from its theoretical antecedents in the early nineteenth century to the brilliant breakthroughs of Darwin and Wallace, to Watson and Crick’s stunning discovery of the DNA double helix, and to the triumphant neo-Darwinian synthesis and rising sociobiology today.Along the way, Larson expertly places the scientific upheaval of evolution in cultural perspective: the social and philosophical earthquake that was the French Revolution; the development, in England, of a laissez-faire capitalism in tune with a Darwinian ethos of “survival of the fittest”; the emergence of Social Darwinism and the dark science of eugenics against a backdrop of industrial revolution; the American Christian backlash against evolutionism that culminated in the famous Scopes trial; and on to today’s world, where religious fundamentalists litigate for the right to teach “creation science” alongside evolution in U.S. public schools, even as the theory itself continues to evolve in new and surprising directions.Throughout, Larson trains his spotlight on the lives and careers of the scientists, explorers, and eccentrics whose collaborations and competitions have driven the theory of evolution forward. Here are portraits of Cuvier, Lamarck, Darwin, Wallace, Haeckel, Galton, Huxley, Mendel, Morgan, Fisher, Dobzhansky, Watson and Crick, W. D. Hamilton, E. O. Wilson, and many others. Celebrated as one of mankind’s crowning scientific achievements and reviled as a threat to our deepest values, the theory of evolution has utterly transformed our view of life, religion, origins, and the theory itself, and remains controversial, especially in the United States (where 90% of adults do not subscribe to the full Darwinian vision). Replete with fresh material and new insights, Evolution will educate and inform while taking readers on a fascinating journey of discovery.From the Hardcover edition.

    Nature hailed it as a book of grand and daunting sweep.... A splendid and rewarding tour de force. And New Scientist wrote that it captured the essence of modern biology, calling it an extremely significant book which, as a bonus, is very readable. Now, in The Origins of Life, Maynard Smith and Szathmary have completely rewritten Transitions to bring their ideas to a wider audience of general readers. Here is a brilliant, state-of-the-art account of how life evolved on earth, focusing primarily on six major transitions--dramatic breakthroughs in the way that information was passed between generations. The authors offer illuminating explorations of the origin of life itself, the arrival of the first cells with nuclei, the first reproduction by sexual means, the appearance of multicellular plants and animals, the emergence of cooperation and of animal societies, and the birth of language. The Origins of Life represents the thinking of two leading scientists on questions that engage us all--how life began and how it gradually evolved from tiny invisible cells into whales and trees and human beings.
