Paleobiologist Anthony D. Barnosky weaves together evidence from the deep past and the present to alert us to the looming Sixth Mass Extinction and to offer a practical, hopeful plan for avoiding it. Writing from the front lines of extinction research, Barnosky tells the overarching story of geologic and evolutionary history and how it informs the way humans inhabit, exploit, and impact Earth today. He presents compelling evidence that unless we rethink how we generate the power we use to run our global ecosystem, where we get our food, and how we make our money, we will trigger what would be the sixth great extinction on Earth, with dire consequences. Optimistic that we can change this ominous forecast if we act now, Barnosky provides clear-cut strategies to guide the planet away from global catastrophe. In many instances the necessary technology and know-how already exist and are being applied to crucial issues around human-caused climate change, feeding the world’s growing population, and exploiting natural resources. Deeply informed yet accessibly written, Dodging Extinction is nothing short of a guidebook for saving the planet.

Product Description: The latest advances in dinosaur ichnology are showcased in this comprehensive and timely volume, in which leading researchers and research groups cover the most essential topics in the study of dinosaur tracks. Some assess and demonstrate state-of-the-art approaches and techniques, such as experimental ichnology, photogrammetry, biplanar X-rays, and a numerical scale for quantifying the quality of track preservation...read more

Cetaceans (whales, dolphins, and porpoises) have fascinated and bewildered humans throughout history. Their mammalian affinities have been long recognized, but exactly which group of terrestrial mammals they descend from has, until recently, remained in the dark. Recent decades have produced a flurry of new fossil cetaceans, extending their fossil history to over 50 million years ago. Along with new insights from genetics and developmental studies, these discoveries have helped to clarify the place of cetaceans among mammals, and enriched our understanding of their unique adaptations for feeding, locomotion and sensory systems. Their continuously improving fossil record and successive transformation into highly specialized marine mammals have made cetaceans a textbook case of evolution - as iconic in its own way as the origin of birds from dinosaurs. This book aims to summarize our current understanding of cetacean evolution for the serious student and interested amateur using photographs, drawings, charts and illustrations.

Provides information on new finds, interpretations of finds, exhibitions, and research in the study of dinosaurs.

Product Description: Here twenty-one leading paleontologists use important refinements in fossil diversity data to provide critical evaluations of older hypotheses of diversification and extinction processes and to propose fresh interpretations.Originally published in 1986...read more

Product Description: One might expect daring of Jack London, an author who has been gold-miner, sailor, frontiersman, adventurer; whose writing can no more be trite or commonplace than can the narrative of his own life history. But no fictionist ever dreamed of daring to attempt what Jack London has done here--to plunge into the gray mist that shrouds the beginnings of our race; to paint in vivid colors a picture of that alleged and disputed ancestor of ours; to outline his brutal life, his loves, his hates, his first efforts toward human reasoning poiver; to do all this with such wonderful vividness that the skeptic is convinced by the plain truth of it...read more
