Approaching dogs as a biological species rather than just as pets, Coppinger and Feinstein accessibly synthesize decades of research and field experiments to explain the evolutionary foundations underlying dog behaviors. They examine the central importance of the shape of dogs:  how their physical body (including the genes and the brain) affects behavior, how shape interacts with the environment as animals grow, and how all of this has developed over time. Shape, they tell us, is what makes a champion sled dog or a Border collie that can successfully herd sheep. Other chapters in How Dogs Work explore such mysteries as why dogs play; whether dogs have minds, and if so what kinds of things they might know; why dogs bark; how dogs feed and forage; and the influence of the early relationship between mother and pup. Going far beyond the cozy lap dog, Coppinger and Feinstein are equally fascinated by what we can learn from the adaptations of dogs, wolves, coyotes, jackals, dingoes, and even pumas in the wild, as well as the behavior of working animals like guarding and herding dogs.   We cherish dogs as family members and deeply value our lengthy companionship with them. But, isn’t it time we knew more about who Fido and Trixie really are? How Dogs Work will provide some keys to unlocking the origins of many of our dogs' most common, most puzzling, and most endearing behaviors.

    Many were fantastic, bizarre creatures that still capture our imagination: the super-predator Tyrannosaurus, the plate-backed Stegosaurus, and the long-necked, long-tailed Diplodocus. Dinosaurs: The Ultimate Guide to How They Lived taps into our enduring interest in dinosaurs, shedding new light on different dinosaur groups. Leading paleontology experts Darren Naish and Paul Barrett trace the evolution, anatomy, biology, ecology, behavior, and lifestyle of a variety of dinosaurs. They also remind us that dinosaurs are far from extinct: they present evidence supporting the evolution of dinosaurs to birds that exist today as approximately ten thousand different species. Throughout their narrative Naish and Barrett reveal state-of-the-art new findings shaping our understanding of dinosaurs. Readers will discover, for example, how the use of CT-scanning enables scientists to look inside dinosaur skulls, thus gaining new insight into their brains and sense organs. Dinosaurs is a must-have for all those wanting to keep up to date about these dynamic, complicated creatures.

    Thanks largely to YouTube clips posted by the sloth orphanage in Costa Rica, sloths have attracted a vast audience of admirers. Instead of seeing them as ridiculous anachronisms of which we know little, they have turned into creatures considered by many to be the most endearing on earth.Over much the same period, scientific investigations have also changed our view of sloths. No longer are they seen as total misfits in the modern world but, in the words of one specialist sloth investigator, they are 'masters of an alternative lifestyle'.In this wonderfully entertaining celebration of this most unique of creatures, William Hartston reveals the fascinating history of the sloth, from the prehistoric ground sloth to modern pygmy sloths in Panama, explores the current state of the science of sloths and reveals the truth behind sloth behaviour.

    Current estimates suggest that the rate of extinction is now thousands of times that counted in the fossil record before the emergence of modern man. At the same time, human societies themselves are in a cultural extinction crisis, with experts anticipating that of the world's nearly seven thousand languages as few as ten percent may survive into the next century. Melanie Challenger's extraordinary book is an exploration of how we might live to resist these extinctions and why such disappearances must be of concern to us. Adventurous, curious and passionate about her subject, Challenger takes us on a very personal journey as she tries to restore her own relationship with nature. The narrative unfolds through a series of landscapes haunted by extinction. From the ruined tin mines of Cornwall and the abandoned whaling stations of South Georgia to the Inuit camps of the Arctic and the white heart of Antarctica, she probes the critical relationship between human activities and environmental collapse. This is the first book to weave together the strands of cultural, biological and industrial extinctions into a meditation on the way we live beside nature in the modern world.

    And survival is never a given. Somehow, a blind, defenseless tiger kitten must evolve into a deadly, efficient predator; a chimp must learn to distinguish edible plants from lethal poisons; a baby buffalo must be able to pick its mother out of a herd of hundreds. Contrary to common belief, not everything is "hardwired" -- or instinctual -- in the animal kingdom. Many skills a wild animal needs to thrive, to grow, to be what nature intended, must be developed through play, painstaking teaching, and often treacherous trial and error. The coming-of-age processes of the myriad creatures of plain, forest, ocean, and jungle are truly fascinating and often astonishing natural events.In Becoming a Tiger, Susan McCarthy, co-author of the critically acclaimed New York Times bestseller When Elephants Weep, offers readers an in-depth look into the amazing ways baby animals learn not only about themselves, but about their world and ours -- and how to survive in both. Based on extensive scientific research done in the lab, in controlled "natural" settings, as well as in the wild, her findings provide stunning new insights into the lives and development of Earth's nonhuman inhabitants -- not only tigers, but lions, bears, bats, rats, birds, dolphins, whales, apes, elephants, and dozens of other species.Sharing stories and discoveries at once captivating, funny, breathtaking, provocative, and heartwarming, Susan McCarthy carries us on a remarkable journey into untamed places, immersing us in the fascinating, complex, and hitherto unimagined societies and cultures of the beasts and birds. Along the way she shines a brilliant new light on subjects scientists, biologists, and zoologists have only begun to explore, revealing startling truths about the behavior, and sometimes humanlike foibles, of creatures great and small.Warm, informative, and beautifully written, Becoming a Tiger is an enthralling reading experience for animal lovers everywhere. In the transformation tales of playful pups, big-footed cubs, and scrawny chicks becoming deadly hunters, able foragers, and deft nest-builders are valuable and enriching life lessons for members of our own inquisitive, ever-developing species.

    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.

    REX springs out, flashing a startling jawful of jagged teeth. Turn the next spread and a ravishing raptor unfurls and appears to fly off the edge of the page.

    The second half of the nineteenth century -- the so-called Gilded Age -- was a time when Americans were exploring the West and building a nation that would stretch from coast to coast.It was also a time of scientific ferment. Charles Darwin had shaken the very foundations of Victorian society with his theory of evolution by natural selection, and scientists across the civilized world were locked in a great battle over Darwin's idea. While the debate raged in Europe, the hunt for hard evidence increasingly focused on the American West, with its grand mesas, buttes, and badlands. "We must turn to the New World if we wish to see in perfection the oldest monuments of earth's history," advised Sir Charles Lyell, the father of modern geology, after a visit to America. "Certainly in no other country are these ancient strata developed on a grander scale or more plentifully charged with fossils."Could the answer to the history of life and the proof of evolution be found in those fossils? That was the question that two young American paleontologists--Edward Drinker Cope and Othniel Charles Marsh--set out to answer. But what began as a friendly contest quickly turned into bitter rivalry that would spill over into American science and politics and rage relentlessly for nearly three decades.        Cope and Marsh would battle on the prairies, in the halls of Congress, in science journals, and in the popular press. Both wealthy men, they launched lavish, western expeditions and raced across the plains and mountains searching for the remains of the magnificent beasts that once inhabited the continent. Along the way they would encounter George Custer, Sitting Bull, Buffalo Bill, and Red Cloud.         Among the most remarkable fossil discoveries of Cope and Marsh are a bevy of dinosaurs, including some of the best known beasts -- the Triceratops, the Stegosaurus, the Camarasaurus, and the Brontosaurus. Even today, Marsh holds the record for dinosaur discoveries.        Just as valuable, however, were some of Marsh's discoveries of ancient mammals and birds that provided the first real proof of Dar- win's theory--"The best support for the theory in twenty years," the great Darwin himself proclaimed.        The tale of Cope and Marsh is also the story of the rise of American science. When their story begins just after the Civil War, America was an intellectual backwater, with eminent scientists snookered by the great, fake stone statue The Cardiff Giant--a hoax unmasked by Marsh.        But even as Cope and Marsh waged war, they both fought to build up American science and its scientific institutions. Yet despite their discoveries and their Gilded Age celebrity, the names of Cope and Marsh have faded into the recesses of the library and archive. In The Gilded Dinosaur Mark Jaffe exhumes from those archives the notes, journals, and letters of Cope and Marsh to reanimate and retell one of the keenest rivalries in the history of science.

    Thanks to cartoons and folk accounts we have a distorted view of these other humans - for that is what they were. We think of them as crude and clumsy and not very bright, easily driven to extinction by the lithe, smart modern humans that came out of Africa some 100,000 years ago.But was it really as simple as that? Clive Finlayson reminds us that the Neanderthals were another kind of human, and their culture was not so very different from that of our own ancestors. In this book, he presents a wider view of the events that led to the migration of the moderns into Europe, what might have happened during the contact of the two populations, and what finally drove the Neanderthals to extinction. It is a view that considers climate, ecology, and migrations of populations, as well as culture and interaction.His conclusion is that the destiny of the Neanderthals and the Moderns was sealed by ecological factors and contingencies. It was a matter of luck that we survived and spread while the Neanderthals dwindled and perished. Had the climate not changed in our favour some 50 million years ago, things would have been very different.There is much current research interest in Neanderthals, much of it driven by attempts to map some of their DNA. But it's not just a question of studying the DNA. The rise and fall of populations is profoundly moulded by the larger scale forces of climate and ecology. And it is only by taking this wider view that we can fully understand the course of events that led to our survival and their demise. The fact that Neanderthals survived until virtually yesterday makes our relationship with them and their tragedy even more poignant. They almost made it, after all.

    The book has undergone three editions, several reprints, and revised reprints in a span of 13 years. There are many biochemistry textbooks in the market. Some of them are purely basic while others are applied, and there are very few books which cover both these aspects together. For this reason, the students learning biochemistry in their undergraduate courses have to depend on multiple books to acquire a sound knowledge of the subject. This book, ‘Biochemistry’ is unique with a simultaneous and equal emphasis on basic and applied aspects of biochemistry. This textbook offers an integration of medical and pure sciences, comprehensively written to meet the curriculum requirements of undergraduate courses in medical, dental, pharmacy, life-sciences and other categories (agriculture, veterinary, etc.). This book is designed to develop in students a sustained interest and enthusiasm to learn and develop the concepts in biochemistry in a logical and stepwise manner. It incorporates a variety of pedagogic aids, besides colour illustrations to help the students understand the subject quickly and to the maximum. The summary and biomedical/clinical concepts are intended for a rapid absorption and assimilation of the facts and concepts in biochemistry. The self-assessment exercises will stimulate the students to think rather than merely learn the subject. In addition, these exercises (essays, short notes, fill in the blanks, multiple choice questions) set at different difficulty levels, will cater to the needs of all the categories of learners.New to This Edition The book offers an integration of medical and pure sciences, and is comprehensively written, revised and updated to meet the curriculum requirements of Medical, Pharmacy, Dental, Veterinary, Biotechnology, Agricultural Sciences, Life Sciences, and others studying Biochemistry as one of the subjects. It is the first text book on Biochemistry in English with multi-colour illustrations by an author from Asia. The use of multicolours is for a clearer understanding of the complicated biochemical reactions. It is written in a lucid style with the subject being presented as an engaging story growing from elementary information to the most recent advances, and with theoretical discussions being supplemented with illustrations, flowcharts, and tables for easy understanding of Biochemistry. It has each chapter beginning with a four-line verse followed by the text, biomedical concepts, a summary, and self-assessment exercises. The lively illustrations and text with appropriate headings and sub-headings in bold type faces facilitate reading path clarity and quick recall. It provides the most recent and essential information on Molecular Biology and Biotechnology, Diabetes, Cancer, Free Radicals, Free radicals and Antioxidants, Prostaglandins, etc. It describes a wide variety of case studies and biochemical correlations and several newer biomedical aspects- Metabolic syndrome, Therapeutic diets, Atkins diet, Trans fatty acids, Epigenetics, Nutrigenomics, Recombinant ribozymes, Membrane transport disorders, Pleural fluid etc. It contains the basics (Bioorganic and Biophysical Chemistry, Tools of Biochemistry, Immunology, and Genetics) for beginners to learn easily Biochemistry, origins of biochemical words, confusables in Biochemistry, principles of Practical Biochemistry, and Clinical Biochemistry Laboratory.

    Indeed, starting from this tiny, common speck, Jan Zalasiewicz offers readers a stimulating tour that begins with the Universe's dramatic birth in the unimaginable violence of the Big Bang and explores the construction of the Solar System and the origins of our own planet. Zalasiewicz shows the almost incredible complexity present in the apparently mundane pebble, starting with the astonishing number of atoms in each. We learn that many events in the Earth's ancient past can be deciphered from a pebble: volcanic eruptions; the lives and deaths of extinct animals and plants; the alien nature of long-vanished oceans; and even the creations of fool's gold and oil deep underground. Zalasiewicz also demonstrates how geologists reach deep into the Earth's past by forensic analysis of even the tiniest amounts of mineral matter. The pebble may be small, and ordinary, but it is also an eloquent part of our Earth's extraordinary, never-ending story.

    Theologians quickly labeled Charles Darwin the most dangerous man in England, and, as the Saturday Review noted, the uproar over the book quickly "passed beyond the bounds of the study and lecture-room into the drawing-room and the public street." Yet, after reading it, Darwin's friend and colleague T. H. Huxley had a different reaction: "How extremely stupid not to have thought of that."Based largely on Darwin's experience as a naturalist while on a five-year voyage aboard H.M.S. Beagle, The Origin of Species set forth a theory of evolution and natural selection that challenged contemporary beliefs about divine providence and the immutability of species. A landmark contribution to philosophical and scientific thought, this edition also includes an introductory historical sketch and a glossary Darwin later added to the original text.Charles Darwin grew up considered, by his own account, "a very ordinary boy, rather below the common standard of intellect." A quirk of fate kept him from the career his father had deemed appropriate--that of a country parson--when a botanist recommended Darwin for an appointment as a naturalist aboard H.M.S. Beagle from 1831 to 1836. Darwin is also the author of the five-volume work Zoology of the Voyage of the Beagle (1839) and The Descent of Man (1871).From the Trade Paperback edition.

    Using this example as a springboard, David M. Raup leaps into an egaging discussion of the theories, assumptions, and difficulties associated with the science of species extinction. Woven is along the way are stories of the trilobite eye, tropical reefs, flying reptiles, and the fate of the heath hen on Martha's Vineyard, a very modern extinction.
