Colorful and easy to use, this guide for the identification of shells includes general information on mollusks and advice on shell collecting and study.

    As evidenced in the record, whales evolved from herbivorous forest-dwelling ancestors that resembled tiny deer to carnivorous monsters stalking lakes and rivers and to serpentlike denizens of the coast. Thewissen reports on his discoveries in the wilds of India and Pakistan, weaving a narrative that reveals the day-to-day adventures of fossil collection, enriching it with local flavors from South Asian culture and society. The reader senses the excitement of the digs as well as the rigors faced by scientific researchers, for whom each new insight gives rise to even more questions, and for whom at times the logistics of just staying alive may trump all science. In his search for an understanding of how modern whales live their lives, Thewissen also journeys to Japan and Alaska to study whales and wild dolphins. He finds answers to his questions about fossils by studying the anatomy of otters and porpoises and examining whale embryos under the microscope. In the book's final chapter, Thewissen argues for approaching whale evolution with the most powerful tools we have and for combining all the fields of science in pursuit of knowledge.

    The prolonged encounter between the Cro-Magnons and the archaic Neanderthals and between 45,000 and 30,000 years ago was one of the defining moments of history. The Neanderthals survived for some 15,000 years in the face of the newcomers, but were finally pushed aside by the Cro-Magnons' vastly superior intellectual abilities and cutting-edge technologies, which allowed them to thrive in the intensely challenging climate of the Ice Age.What do we know about this remarkable takeover? Who were the first modern Europeans and what were they like? How did they manage to thrive in such an extreme environment? And what legacy did they leave behind them after the cold millennia? The age of the Cro-Magnons lasted some 30,000 years?longer than all of recorded history. Cro-Magnon is the story of a little known, yet seminal, chapter of human experience.

    Over time, seahorses have surfaced in some unlikely places. We see them immortalized in the decorative arts; in tribal folklore, literature, and ancient myth; and even on the pages of the earliest medical texts, prescribed to treat everything from skin complaints to baldness to flagging libido. Marine biologist Helen Scales eloquently shows that seahorses are indeed fish, though scientists have long puzzled over their exotic anatomy, and their very strange sex lives?male seahorses are the only males in the animal world that experience childbirth! Our first seahorse imaginings appeared six thousand years ago on cave walls in Australia. The ancient Greeks called the seahorse hippocampus (half-horse, half-fish) and sent it galloping through the oceans of mythology, pulling the sea god Poseidon?s golden chariot. The seahorse has even been the center of a modern-day international art scandal: A two-thousand-year-old winged seahorse brooch was plundered by Turkish tomb raiders and sold to the Metropolitan Museum of Art in New York. A book that is as charming as the seahorse itself, Poseidon?s Steed brings to life an aquatic treasure.Seahorses lead quiet lives, tucked away out of sight on the seafloor. It is rare to catch a glimpse of a seahorse in its natural habitat. But even if few have seen one live, these exotic, seemingly prehistoric creatures exist quite vividly in our imaginations and they have mesmerized scientists, artists, and storytellers throughout time with their otherworldly rarity. Poseidon?s Steed is a sweeping journey that takes us from the coral reefs and seagrass meadows of Indonesia where many seahorses makes their natural habitat to the back streets of Hong Kong where a thriving black market seahorse trade is concealed. Throughout history, seahorses have surfaced in some unexpected places and Scales also follows the seahorse back in time, from our most rudimentary seahorse imaginings six thousand years ago on cave walls in Australia, to the myths of ancient Greece. Scientists have long puzzled over seahorses? unusual anatomy and their very strange sex lives. And male seahorses are the only males in the animal world that experience childbirth! Seahorses are not what scientists call a ?keystone? species. They rely on a healthy ocean to survive, but the marine ecosystem does not rely on them. But their delicate beauty reminds us that we rely on the seas not only to fill our dinner plates, but also to feed our imaginations.

    It is considered the best reference on wolves of its kind.

    But it was not reels of wool or bales of cotton that awaited him, but plants and seeds…Over the next forty years, Bartram would send hundreds of American species to England, where Collinson was one of a handful of men who would foster a national obsession and change the gardens of Britain forever, introducing lustrous evergreens, fiery autumn foliage and colourful shrubs. They were men of wealth and taste but also of knowledge and experience like Philip Miller, author of the bestselling Gardeners Dictionary, and the Swede Carl Linnaeus, whose standardised botanical nomenclature popularised botany as a genteel pastime for the middle-classes; and the botanist-adventurer Joseph Banks and his colleague Daniel Solander who both explored the strange flora of Tahiti and Australia on the greatest voyage of discovery of modern times, Captain Cook’s Endeavour.This is the story of these men – friends, rivals, enemies, united by a passion for plants – whose correspondence, collaborations and squabbles make for a riveting human tale which is set against the backdrop of the emerging empire, the uncharted world beyond and London as the capital of science. From the scent of the exotic blooms in Tahiti and Botany Bay to the gardens at Chelsea and Kew, and from the sounds and colours of the streets of the City to the staggering vistas of the Appalachian mountains, The Brother Gardeners tells the story of how Britain became a nation of gardeners.

    Moral behavior does not begin and end with religion but is in fact a product of evolution.For many years, de Waal has observed chimpanzees soothe distressed neighbors and bonobos share their food. Now he delivers fascinating fresh evidence for the seeds of ethical behavior in primate societies that further cements the case for the biological origins of human fairness. Interweaving vivid tales from the animal kingdom with thoughtful philosophical analysis, de Waal seeks a bottom-up explanation of morality that emphasizes our connection with animals. In doing so, de Waal explores for the first time the implications of his work for our understanding of modern religion. Whatever the role of religious moral imperatives, he sees it as a “Johnny-come-lately” role that emerged only as an addition to our natural instincts for cooperation and empathy.But unlike the dogmatic neo-atheist of his book’s title, de Waal does not scorn religion per se. Instead, he draws on the long tradition of humanism exemplified by the painter Hieronymus Bosch and asks reflective readers to consider these issues from a positive perspective: What role, if any, does religion play for a well-functioning society today? And where can believers and nonbelievers alike find the inspiration to lead a good life?Rich with cultural references and anecdotes of primate behavior, The Bonobo and the Atheist engagingly builds a unique argument grounded in evolutionary biology and moral philosophy. Ever a pioneering thinker, de Waal delivers a heartening and inclusive new perspective on human nature and our struggle to find purpose in our lives.

    As singular and strange as some of the weapons we encounter on these pages are, we learn that similar factors set their evolution in motion. Emlen uses these patterns to draw parallels to the way we humans develop and employ our own weapons, and have since battle began. He looks at everything from our armor and camouflage to the evolution of the rifle and the structures human populations have built across different regions and eras to protect their homes and communities. With stunning black and white drawings and gorgeous color illustrations of these concepts at work, Animal Weapons brings us the complete story of how weapons reach their most outsized, dramatic potential, and what the results we witness in the animal world can tell us about our own relationship with weapons of all kinds.

    Stringer's new theory, based on archeological and genetic evidence, holds that distinct humans coexisted and competed across the African continent—exchanging genes, tools, and behavioral strategies.Stringer draws on analyses of old and new fossils from around the world, DNA studies of Neanderthals (using the full genome map) and other species, and recent archeological digs to unveil his new theory. He shows how the most sensational recent fossil findings fit with his model, and he questions previous concepts (including his own) of modernity and how it evolved.Lone Survivors will be the definitive account of who and what we were, and will change perceptions about our origins and about what it means to be human.

    The prairies are the heartland of the continent, a vast, windswept plain that flows from Alberta south to Texas and from the Rockies east to the Mississippi River.

    Lopez’s classic, careful study has won praise from a wide range of reviewers and improved the way books on wild animals are written. Of Wolves and Men explores the uneasy interaction between wolves and civilization over the centuries, and the wolf's prominence in our thoughts about wild creatures. Drawing upon an impressive array of literature, history, science, and mythology as well as extensive personal experience with captive and free-ranging wolves, Lopez argues for the wolf's preservation and immerses the reader in its sensory world, creating a compelling portrait of the wolf both as a real animal and as imagined by different kinds of men. A scientist might perceive the wolf as defined by research data, while an Eskimo hunter sees a family provider much like himself. For many Native Americans the wolf is also a spiritual symbol, a respected animal that can strengthen the individual and the community. With irresistible charm and elegance, Of Wolves and Men celebrates careful scientific fieldwork, dispels folklore that has enabled the Western mind to demonize wolves, explains myths, and honors indigenous traditions, allowing us to understand how this remarkable animal has become so prominent for so long in the human heart.

    Over the past century it has been known by many names -- the Bone War, the Fossil Feud -- but the tragic story of the competition for fame and natural treasure between Edward Drinker Cope and Othniel Charles Marsh, two leading paleontologists of the Gilded Age, remains prophetic of the conquest of the West as well as a watershed event in science. With a historian's eye and a novelist's skill, David Rains Wallace charts in fascinating detail the unrestrained rivalry between Cope and Marsh and their obsession to become the first to make available to the world the abundant, unknown fossils of the western badlands. This story will surely fascinate anyone who has had to confront the myriad facets of professional jealousy, its sterile brooding, and how it leads to an emotional abyss.
