Carnivoran Evolution
Members of the mammalian clade Carnivora have invaded nearly every continent and ocean, evolving into bamboo-eating pandas, clam-eating walruses and of course, flesh-eating sabre-toothed cats. With this ecological, morphological and taxonomic diversity and a fossil record spanning over sixty million years, Carnivora has proven to be a model clade for addressing questions of broad evolutionary significance. This volume brings together top international scientists with contributions that focus on current advances in our understanding of carnivoran relationships, ecomorphology and macroevolutionary patterns. Topics range from the palaeoecology of the earliest fossil carnivorans to the influences of competition and constraint on diversity and biogeographic distributions. Several studies address ecomorphological convergences among carnivorans and other mammals with morphometric and Finite Element analyses, while others consider how new molecular and palaeontological data have changed our understanding of carnivoran phylogeny. Combined, these studies also illustrate the diverse suite of approaches and questions in evolutionary biology and palaeontology.
Out of Africa I
For the first two thirds of our evolutionary history, we hominins were restricted to Africa. Dating from about two million years ago, hominin fossils first appear in Eurasia. This volume addresses many of the issues surrounding this initial hominin intercontinental dispersal. Why did hominins first leave Africa in the early Pleistocene and not earlier? What do we know about the adaptations of the hominins that dispersed - their diet, locomotor abilities, cultural abilities? Was there a single dispersal event or several? Was the hominin dispersal part of a broader faunal expansion of African mammals northward? What route or routes did dispersing populations take?
Evolution of Cenozoic Land Mammal Faunas and Ecosystems
This volume presents an array of different case studies which take as primary material data sourced from the NOW (‘New and Old Worlds’) database of fossil mammals. The NOW database was one of the very first large paleobiological databases, and since 1996 it has been expanded from including mainly Neogene European land mammals to cover the entire Cenozoic at a global scale. In the last two decades the number of works that are based in the use of huge databases to explore ecological and evolutionary questions has increased exponentially, and even though the importance of big data in paleobiological research has been outlined in selected chapters of general works, no volume has appeared bef...
Lothagam
Located at the southwest corner of Lake Turkana in northern Kenya, Lothagam represents one of the most important intervals in African prehistory. Early human remains are restricted in distribution to Africa and the acquisition of an upright bipedal striding gait, the hallmark of humanity, appears to be at least circumstantially linked to the reduction of equatorial forests and the spread of grasslands on that continent. The diverse Lothagam fauna documents the end-Miocene transition from forested to more open habitats that were exploited by grazing horses and antelopes, hippos, giant pigs, and true elephants. It also includes spectacularly complete fossil carnivore skeletons and some of the oldest human remains. Enlisting a team of highly qualified specialists, this book provides the geologic context and dating framework for the Lothagam fossiliferous sequences, describes the immense diversity of vertebrate fossils recovered from the Late Miocene and Early Pliocene sediments, and synthesizes the results to interpret the changing paleoenvironments that prevailed at this site. The book will interest anthropologists, paleontologists, geologists, and anyone interested in human origins.
Dogs
Xiaoming Wang and Richard H. Tedford combine their research with Mauricio Anton's impeccable reconstructions to present a remarkable portrait of canids over the past 40 million years. Wang and Tedford cull their history from the most recent scientific research conducted on the vast collections of the American Museum of Natural History and other leading institutions. With their rich fossil record, diverse adaptations to various environments, and different predatory specializations, canids are an ideal model organism for the mapping of predator behavior and morphological specializations. They also offer an excellent contrast to felids, which remain entrenched in extreme predatory specializations. The innovative illustrated approach of this book transforms the science of paleontology into a thrilling visual experience, and it forms the perfect accompaniment to an extremely important branch of animal and fossil study.
Messages from Islands
Messages from Islands is a synthetic tour of the world of biodiversity species and their communitiesand the habitats in which they live. It looks at how biodiversity is generated in the course of evolution and how is it maintained over time. The itinerary of the tour is question based. What is causing the current biodiversity crisis ? What is extinction threshold and what is extinction debt? What is the biodiversity hypothesis about rapidly increasing allergies, asthma, and other chronic inflammatory disorders? What is the third-of-third rule, and could it be the solution to habitat conservation? Each chapter begins on an island, with reflections of his own studies and observations about bio...
The Nature of Diversity
All living things on earth—from individual species to entire ecosystems—have evolved through time, and evolution is the acknowledged framework of modern biology. Yet many areas of biology have moved from a focus on evolution to much narrower perspectives. Daniel R. Brooks and Deborah A. McLennan argue that it is impossible to comprehend the nature of life on earth unless evolution—the history of organisms—is restored to a central position in research. They demonstrate how the phylogenetic approach can be integrated with ecological and behavioral studies to produce a richer and more complete picture of evolution. Clearly setting out the conceptual, methodological, and empirical founda...
The Evolution of Everything
Big History seeks to retell the human story in light of scientific advances by such methods as radiocarbon dating and genetic analysis. This book provides a deep, causal view of the forces that have shaped the universe, the earth, and humanity. Starting with the Big Bang and the formation of the earth, it traces the evolutionary history of the world, focusing on humanity's origins. It also explores the many natural forces shaping humanity, especially the evolution of the brain and behaviour. Moving through time, the causes of such important transformations as agriculture, complex societies, the industrial revolution, the enlightenment, and modernity are placed in the context of underlying changes in demography, learning, and social organization. Humans are biological creatures, operating with instincts evolved millions of years ago, but in the context of a rapidly changing world, and as we try to adapt to new circumstances, we must regularly reckon with our deep past.
Carnivore Behavior, Ecology, and Evolution
Because carnivores are at the top of the food chain, their status is an important indicator of the health of the world ecosystem. They are intensely interesting to zoologists and uniquely intriguing to the general public. Devoted primarily to terrestrial carnivores, this volume focuses on such themes as carnivore reintroduction programs and the ethics of studying carnivores, drawing examples from a variety of species. The need to evaluate new conceptual ideas and empirical data inspired this volume of Carnivore Behavior, Ecology, and Evolution, a complement to the original book. In the eight years since publication of the first volume, conservation has emerged as a thematic imperative. The s...
Paleoindian Societies of the Coastal Southeast
The late Pleistocene-early Holocene landscape hosted more species and greater numbers of them in the Southeast compared to any other region in North America at that time. Yet James Dunbar posits that a misguided reliance on using Old World origins to validate New World evidence has stalled research in this area. Rejecting the one-size-fits-all approach to Pleistocene archaeological sites, Dunbar analyzes five areas of contextual data—stratigraphy; chronology; paleoclimate; the combined consideration of habitat, resource availability, and subsistence; and artifacts and technology—to resolve unanswered questions surrounding the Paleoindian occupation of the Americas. Through his extensive ...
