Human life, and how we came to be, is one of the greatest scientific and philosophical questions of our time. This compact and accessible book presents a modern view of human evolution. Written by a leading authority, it lucidly and engagingly explains not only the evolutionary process, but the technologies currently used to unravel the evolutionary past and emergence of Homo sapiens. By separating the history of palaeoanthropology from current interpretation of the human fossil record, it lays numerous misconceptions to rest, and demonstrates that human evolution has been far from the linear struggle from primitiveness to perfection that we've been led to believe. It also presents a coherent scenario for how Homo sapiens contrived to cross a formidable cognitive barrier to become an extraordinary and unprecedented thinking creature. Elegantly illustrated, Understanding Human Evolution is for anyone interested in the complex and tangled story of how we came to be.

This new text sets out to establish the key role played by systematics in deciphering patterns of evolution from the fossil record. It begins by considering the nature of the species in the fossil record and then outlines recent advances in the methodology used to establish phylogenetics relationships, stressing why fossil evidence can be crucial. The way species are grouped into higher taxa, and how this affects their utility in evolutionary studies is also discussed. Because the fossil record abounds with sampling and preservational biases, the book emphasizes that observed patterns can rarely be taken at face value. It is argued that evolutionary trees, constructed from combining phylogenetic and biostratigraphic data, provide the best approach for investigating patterns of evolution through geologic time.
The only integrated text covering the study of evolutionary patterns from a phylogenetic stance.

The early Mesozoic period was a critical period in the evolution of life on land when most of today's major groups of terrestrial vertebrates arose and dinosaurs and pterosaurs rose to prominence. In recent years this period has received a great deal of attention from palaeontologists, and it is now felt that the small vertebrates which lived in the shadows of the first dinosaurs tell us a great deal about the evolution of modern terrestrial ecosystems. This book attempts to collate all the information on the small vertebrates and features contributions by experts with international reputations in their fields. There are chapters on the taxonomy and phylogeny of the key vertebrate groups, followed by a section dealing with the most significant fossiliferous assemblages worldwide. The final section looks at how faunal turnover at this time is measured and examines the possibility of mass extinctions.

The family Equidae have an extensive fossil record spanning the past 58 million years, and the evolution of the horse has frequently been used as a classic example of long-term evolution. In recent years, however, there have been many important discoveries of fossil horses, and these, in conjunction with such new methods as cladistics, and techniques such as precise geochronology, have allowed us to achieve a much greater understanding of the evolution and biology of this important group. This book synthesizes the large body of data and research relevant to an understanding of fossil horses from several disciplines including biology, geology and paleontology. Using horses as the central theme, the author weaves together in the text such topics as modern geochronology, paleobiogeography, climate change, evolution and extinction, functional morphology, and population biology during the Cenozoic period. This book will be exciting reading for researchers and graduate students in vertebrate paleontology, evolution, and zoology.

The Lower Thames Valley is a classic area for British Pleistocene studies. The valley contains a sequence of River Thames deposits representing approximately the past 300,000 years, including older, highly fragmented and eroded sediments derived from Thames tributaries and glaciation. The region includes some of the most important Palaeolithic archaeological sites in the country which, although extensively studied, have never previously been fitted into a regional context. The area also includes some of the most important fossiliferous localities in the country, several of which have been at the center of controversies regarding the sequence of events in the British Pleistocene. This regional investigation clarifies the problems by presenting the geological sequence in detail and establishing the relationship of these localities for the first time.

Most nonscientists are usually aware of fossils, and it is commonly believed that they are extremely rare. In fact, fossils are exceptionally common in many sedimentary rocks and are used extensively in geology for age dating, interpretation of ancient environments, and the discovery of natural resources. However, there is another type of fossil deposit that is truly rare. These rare fossil deposits, called Lagerst?tten, preserve the remains of the soft tissues or the articulated skeletal remains of ancient creatures in truly astonishing fine detail. Some of these deposits are world-famous, such as the Burgess Shale, or Solnhofen but there are others dating from many different geological eras from the Paleozoic, up to the Eocene. Recently, a concerted effort has been made to understand the overall significance of these rare fossil deposits. Whereas in the past these deposits were considered novelties, modern researchers are trying to understand what they can tell us about ancient life and environments. New sophisticated techniques (including image and geochemical analyses) are providing enormous new contributions to our knowledge of Lagerst?tten sites and to paleobiology in general.

This volume describes many of the most famous Lagerst?tten locations worldwide and is complete with over 70 superb halftones showing some of these exotic fossils in all their glory. Paleontologists are beginning to understand why such deposits occur, how they have varied since the advent of marine metazoan life, and how their presence effects our understanding of the evolution of life in the Earth's oceans. In this way, the study of Lagerst?tten continues to move towards the mainstream of paleobiological, biological, and geological research, and away from its former status as the examination of mere curiosities.

All those interested in these beautiful and sometimes enigmatic deposits will want to own this book.

Breathtaking in scope, this is the first survey of the entire
ecological history of life on land--from the earliest traces
of terrestrial organisms over 400 million years ago to the
beginning of human agriculture. By providing myriad insights
into the unique ecological information contained in the
fossil record, it establishes a new and ambitious basis for
the study of evolutionary paleoecology of land ecosystems.
A joint undertaking of the Evolution of Terrestrial
Ecosystems Consortium at the National Museum of Natural
History, Smithsonian Institution, and twenty-six additional
researchers, this book begins with four chapters that lay out
the theoretical background and methodology of the science of
evolutionary paleoecology. Included are a comprehensive
review of the taphonomy and paleoenvironmental settings of
fossil deposits as well as guidelines for developing
ecological characterizations of extinct organisms and the
communities in which they lived. The remaining three
chapters treat the history of terrestrial ecosystems through
geological time, emphasizing how ecological interactions have
changed, the rate and tempo of ecosystem change, the role of
exogenous "forcing factors" in generating ecological change,
and the effect of ecological factors on the evolution of
biological diversity.
The six principal authors of this volume are all associated
with the Evolution of Terrestrial Ecosystems program at the

This new edition of a successful textbook describes and explains in a refreshingly clear way the origin and evolution of plants revealed by the fossil record, and summarizes paleobotanical information relevant to our present understanding of the relationships between the major plant groups, extant and extinct. New ideas and theories pertaining to such topics as the origin and evolution of eucaryotes, the early evolution of ferns, the origin of seeds, and the origin and early evolution of gymnosperms and angiosperms are included, as is the cladistic method and its results. Paleoecology is a theme discussed in the new edition, ranging from the Precambrian to the Tertiary, with a new chapter wholly devoted to the paleoecology of Pennsylvanian coal swamps. One of the major additions is a new chapter discussing the paleobotany of the flowering plants, a topic that was given only a brief treatment in the first edition. As in the first edition the text is profusely illustrated with line illustrations and halftones. For those students with little knowledge of plant structure and morphology there is a brief resumé of those features of extant plants that will be needed to gain a better understanding of the fossil record. Summarizing charts are also used to help students visualize the interpretative material. All of the summarizing charts have been updated and they reflect new ideas about the relationships and temporal distributions of the major plant groups. The quantity of illustrations in this new edition has been increased. In particular, there are more photographs of actual fossil material and there are reconstructions of many ancient plants that are now more-or-less completely understood. The book is designed so that selected parts can be used for one-semester undergraduate courses or graduate seminars in paleobotany where the subject material is limited or for two-semester courses. It can also be used as a supplement to courses in evolutionary botany, morphology and anatomy.

The changes in the Earth's climate over the past 600 million years, from the Cambrian to the Quaternary, come under scrutiny in this book. The geological evidence for ancient climates is examined, such as the distribution of climate-sensitive sediments - including coals, evaporites and glacial deposits, the environmental tolerances of fossil plants and animals, and the geochemical record. The Earth's climate has changed many times throughout the Phanerozoic. Thus in this book the climate history has been divided into Warm and Cool modes, intervals when either the Earth was in a former 'greenhouse' state with higher levels of atmospheric CO2 and polar regions free of ice, or the global climate was cooler and ice was present in high latitudes. What are the causes of climatic change? The studies presented here highlight the complex interactions between the carbon cycle, continental distribution, tectonics, sea level variation, ocean circulation and temperature change as well as other parameters. In particular, the potential of the carbon isotope records as an important signal of the past climates of the Earth is explored.

In recent years dinosaurs have captured the attention of the public at an unprecedented scale. At the heart of this resurgence in popular interest is an increased level of research activity, much of which is innovative in the field of palaeontology. For instance, whereas earlier palaeontological studies emphasized basic morphologic description and taxonomic classification, modern studies attempt to examine the role and nature of dinosaurs as living animals. More than ever before, we understand how these extinct species functioned, behaved, interacted with each other and the environment, and evolved. Nevertheless, these studies rely on certain basic building blocks of knowledge, including facts about dinosaur anatomy and taxonomic relationships. One of the purposes of this volume is to unravel some of the problems surrounding dinosaur systematics and to increase our understanding of dinosaurs as a biological species. Dinosaur Systematics presents a current overview of dinosaur systematics using various examples to explore what is a species in a dinosaur, what separates genders in dinosaurs, what morphological changes occur with maturation of a species, and what morphological variations occur within a species.

When fossils of birds from China's Jehol region first appeared in scientific circles, the world took notice. These Mesozoic masterpieces are between 120 and 131 million years old and reveal incredible details that capture the diversity of ancient bird life. Paleontologists all over the world began to collaborate with Chinese colleagues as new and wondrous fossil-related discoveries became regular events. The pages of National Geographic and major scientific journals described the intricate views of feathers as well as food still visible in the guts of these ancient birds. Now, for the first time, a sweeping collection of the most interesting of Jehol's avian fossils is on display in this beautiful book. Birds of Stone makes visible the unexpected avian diversity that blanketed the earth just a short time (geologically speaking) after a dinosaur lineage gave rise to the first birds. Our visual journey through these fossils is guided by Luis M. Chiappe, a world expert on early birds, and Meng Qingjin, a leading figure in China's natural history museum community. Together, they help us understand the "meaning" of each fossil by providing straightforward narratives that accompany the full-page photographs of the Jehol discoveries. Anyone interested in the history of life-from paleontologists to inquisitive birders-will find Birds of Stone an irresistible feast for the eyes and mind.

One of the most important questions we can ask about life is "Does ecology matter?" Most biologists and paleontologists are trained to answer "yes," but the exact mechanisms by which ecology matters in the context of patterns that play out over millions of years have never been entirely clear. This book examines these mechanisms and looks at how ancient environments affected evolution, focusing on long-term macroevolutionary changes as seen in the fossil record.

Evolutionary paleoecology is not a new discipline. Beginning with Darwin, researchers have attempted to understand how the environment has affected evolutionary history. But as we learn more about these patterns, the search for a new synthetic view of the evolutionary process that integrates species evolution, ecology, and mass extinctions becomes ever more pressing. The present volume is a benchmark sampler of active research in this ever more active field.

The question of the existence of other worlds and other living beings has been present in the human quest for knowledge since as far as Epicurus. For centuries this question belonged to the fields of philosophy and theology. The theoretical problem of the formation of the Solar System, and hence of other planetary systems, was tackled only during the 18th century, while the first observational attempts for a detection started less than one hundred years ago. Direct observation of an extra-solar planetary system is an extraordinarily difficult problem: extra-solar planets are at huge distances, are incredibly faint and are overwhelmed by the bright light of their own stars. With virtually no observational insight to test their models, theoreticians have remained for decades in a difficult position to make substantial progress. Yet, the field of stellar formation has provided since the 1980s both the the oretical and observational evidences for the formation of discs at the stage of star birth and for debris materials orbiting the very young stellar systems. It was tempting to consider that these left-overs might indeed later agglomerate into planetary systems more or less similar to ours. Then came observational evidences for planets outside the Solar System.

Tracking Dinosaurs is the first non-technical, popular science book on dinosaur footprints and what they reveal about dinosaurs and their habitats. Billions of dinosaur tracks have been found in recent years and through careful examination of these prehistoric clues, dinosaur trackers have discovered much about how and where dinosaurs lived. This book deals with this landslide of new information that has accumulated in recent decades, demonstrating that fossil footprints are neither rare nor insignificant as previously supposed. A complete guide to dinosaur tracking, the book begins with a discussion of the meaning of tracks, how tracks provide information about dinosaur locomotion, behaviour, ecology and environmental impact. The accessible writing style and numerous illustrations, including eight pages of colour photographs, make this book appropriate for all people with a general interest in science and natural history.

This interdisciplinary book interprets early human evolution in the context of the local ecology and adaptation to specific habitats. It systematically assesses the possible role of climate change in driving early human evolution, and evaluates recent fossil finds from an ecological and biogeographic perspective, to provide a novel synthesis of hominid evolution.

The study of fossilized dinosaur remains, vertebrate paleontology is a well established discipline, but the discovery and rediscovery of numerous and varied dinosaur footprints and nest sites has spurred a renaissance in the associated field of ichnological research. Dinosaur Tracks and Traces is the first book ever to be devoted to this subject, and it represents the work of seventy noted dinosaur ichnologists. Contributors address the history of science and the relevance of dinosaur ichnology to the interpretation of dinosaur behaviour, paleoecology, paleoenvironments, and evolution. Several new preservation, conservation, and documentation techniques are also presented. The book is richly illustrated and is intended for students and professionals in the areas of paleontology, vertebrate zoology, geology, and paleoenvironmental analysis. The historical aspects of the book and the many site descriptions also make Dinosaur Tracks and Traces appealing to amateur fossil collectors and dinosaur enthusiasts.

The long and distinguished tradition of tracking dinosaurs and other extinct animals in Europe dates back to the 1830s. Yet this venerable tradition of scientific activity cannot compare in magnitude and scope with the unprecedented spate of discovery and documentation of the last few years. Now, following on the heels of his "Dinosaur Tracks and Other Fossil Footprints of the Western United States, " Martin Lockley teams up with Christian Meyer to present an up to date synthesis of the recent findings in the field of European fossil footprints. Drawing extensively on their own research results from studies in Britain, Switzerland, Portugal, Spain, and elsewhere, the authors create a dynamic picture of mammal, reptile, bird, and amphibian "track-makers" throughout more than 300 million years of vertebrate evolution, placed in the context of Europe's changing ancient environments.

Beginning with an introduction to tracking and a history of the European tracking tradition, "Dinosaur Tracks and Other Fossil Footprints of Europe" then charts a broad path of evolutionary proliferation from the proto-dinosaurs of the Early Triassic period to the dinosaurs' decline and disappearance in the Upper Cretaceous. The survey continues into the age of mammals and birds, ending with the cave art of our Paleolithic ancestors.

"A rich historical pastiche of 17th- and 18th-century philosophy, science, and religion."--G. Y. Craig, "New Scientist "
"This book, by a distinguished Italian historian of philosophy, is a worthy successor to the author's important works on Francis Bacon and on technology and the arts. First published in Italian (in 1979), it now makes available to English readers some subtly wrought arguments about the ways in which geology and anthropology challenged biblical chronology and forced changes in the philosophy of history in the early modern era. . . . [Rossi] shows that the search for new answers about human origins spanned many disciplines and involved many fascinating intellects--Bacon, Bayle, Buffon, Burnet, Descartes, Hobbes, Holbach, Hooke, Hume, Hutton, Leibniz, de Maillet, Newton, Pufendorf, Spinoza, Toland, and, most especially, Vico, whose works are impressively and freshly reevaluated here."--Nina Gelbart, " American Scientist

Paleoethnobotany offers powerful tools for reconstructing past cultures by examining the interaction of human populations with the plant world. Plant remains from archaeological sites can provide information for a number of disciplines: archaeologists may use such remains to examine how plants were used, how agriculture changed over time, or how plant offerings in burials signaled social status; ecologists and botanists may use them to study morphological changes in plants due to domestication.
Combining case studies and theoretical discussions, Current Paleoethnobotany presents the first full discussion of the major stages and problems of paleoethnobotanical research, from designing and testing equipment, such as flotation machines, to quantification and interpretation. The volume explores a wide range of issues concerning collection techniques, analytical procedures, and interpretive models that will provide accurate information about past human societies from plant remains. The contributors offer data on specific regions as well as more general background information on the basic techniques of paleoethnobotany for the nonspecialist. Throughout, they explicitly examine the assumptions underlying paleoethnobotanical methods and the ways in which those assumptions affect anthropological and ecological research questions.
Based on a symposium presented at the 1985 meeting of the Society for American Archaeology, Current Paleoethnobotany moves beyond a technique-oriented view of paleoethnobotany to successfully integrate current thinking about both procedures and research goals. The contributors demonstrate the potential value of the field of paleoethnobotany and open the way for further discussion and improvement.

This book discusses procedures for handling information derived from the fossil record, and the application of this information to solving problems in geological succession and earth history. The main purpose of the book is to analyse shortcomings of the existing procedures, and to propose in their place an alternative set of data-handling arrangements of much greater simplicity and efficiency. The author argues that the procedures in current use are cumbersome and inefficient, and that, partly as a consequence of these information-handling methods, palaeontology has failed to make advances commensurate with technological improvements. In this book he proposes a system which could make possible the integrated use of every detail of geological information taken from the rocks. This would achieve better resolution in sequence correlation, in paleoecologic interpretation and in logging the course of evolution. Compatibility of style with existing records has been maintained to avoid any danger of loss of valuable data, and to simplify the process of reevaluating old records. The book will be of interest to all paleontologists, particularly those dealing with microfossils, and is intended to stimulate discussion and criticism of both the analysis and the proposals.

This book is volume 33 of the yearbook series 'Palaeoecology of Africa' presenting the outcome of a 'tribute conference' to the internationally recognized South African researcher and palynologist Professor Louis Scott. He has recently retired, but is continuing his active research career. The conference proceedings and articles published here highlight and celebrate Prof. Scott's contribution to palaeoscience and to the natural sciences in general. The conference was organized in July 2014 by the National Museum, Bloemfontein and the University of the Free State, South Africa, and focused on both past and present environments, ecosystems and climates of the arid regions of southern Africa, an area that serves as major focus of Prof. Scott's research. Louis Scott's research interests include stratigraphic palynology, long-term continental environmental change during the Cainozoic, and interpretation of palaeoenvironmental records associated with archaeological sites. His research has contributed insights into the origin of our current environment by identifying long-term patterns of climate change. Results have been applied in numerical models of vegetation change in Africa and globally. The results of these studies are relevant across the fields of botany, geology, climatology, archaeology, anthropology and palaeontology. The chapters revisit and discuss the scientific work of Prof. Scott: among others the reconstructions of vegetation and climatic history in various areas of southern Africa, including the Tswaing Crater with a record of 200 000 years, that give insights into environmental conditions during the Last Glacial Period and the subsequent development of modern conditions. Some observations also provide key baseline information, contributing to understanding past human and environmental contexts and climatic change and the effects of global warming.

One of the first interdisciplinary discussions of taphonomy (the study of how fossil assemblages are formed) and paleoecology (the reconstruction of ancient ecosystems), this volume helped establish these relatively new disciplines. It was originally published as part of the influential Prehistoric Archeology and Ecology series. Taphonomy is plainly here to stay, and this book makes a first class introduction to its range and appeal.--Anthony Smith, Interdisciplinary Science Reviews

Presenting new data on the now classical aspects of Gondwana geology, this work also highlights the increasing international interest as to how the Gondwana supercontinent was assembled. The book is organized according to three themes: assembly, evolution and dispersal, containing 57 papers of specialists in the area.
Assembly: Late Proterozoic-Early Palaeozoic mobile belts of Gondwana, South America, Africa & Australo-Antarctica.
Evolution: Detailed palynological & palaeontological research of Late Palaeozoic- Mesozoic palaeoclimate.
Dispersal: Novel approach to predicting past plate motions followed by series of papers covering the break-up history of Gondwana;

Around 210 million years ago, life on Earth experienced sweeping changes. Many archaic reptiles and mammalian predecessors became extinct and were replaced by dinosaurs, pterosaurs, crocodiles, turtles, mammals, and essentially all of the major modern vertebrate groups except the birds. This period of change, which took place over a period of approximately five to ten million years, ushered in the beginning of the 'Age of Dinosaurs,' a period that lasted 160 million years to the end of the Cretaceous 65 million years ago. In the past decade, paleontologists have come to know a great deal more about this crucial interval of time. New discoveries, ideas, and insights from scientists in many related- disciplines have created new paradigms about the beginning of the 'Age of Dinosaurs.' What were the animals that preceded the dinosaurs like? How did the dinosaurs originate, and what do we know of their early history? Was their ascent tied to evolutionary innovations, global climatic and ecological changes, or just chance factors? How do paleontologists decide about the evidence preserved in the fossil record, and what areas now require major thought and reevaluation? In this book, 31 specialists in the paleontology of this era consider these and other questions related to Late Triassic and Early Jurassic times - the beginning of the 'Age of Dinosaurs,' its fauna, flora, climate, stratigraphic relationships, and major evolutionary changes. The book is divided into sections on background, Late Triassic taxa and faunas, changes across the boundary, Early Jurassic taxa and faunas, and major macroevolutionary patterns. This comprehensive volume is richly illustrated and is intended for students and professionals in the areas of paleontology, evolutionary biology, geology, and vertebrate zoology. Introductory and summary chapters are provided to acquaint the non-specialist with the issues and the setting of this interval of time in which the ancestral components of the modem fauna, as well as the Dinosauria, first appeared to rule the Earth.
