Book Description
Artiodactyls are diverse and successful hoofed mammals, represented by nearly two hundred living species of pigs, peccaries, hippos, camels, deer, sheep, cattle, giraffes, and other even-toed ungulates. In the recent years, a tremendous amount of research has been conducted on this important order. The Evolution of Artiodactyls synthesizes this research into a single volume. The authors explore a variety of topics, including molecular phylogeny of terrestrial artiodactyls phylogenetic relationships of cetaceans to terrestrial artiodactyls, and the earliest artiodactyls—Diacodexidae, Dichobunidae, Homacodontidae, Leptochoeridae, and Raoellidae.

Book Description
This book is designed as a source and reference for people interested in the history and fossil record of North American tertiary mammals. Each chapter covers a different family or order, and includes information on anatomical features, systematics, the distribution of the genera and species at different fossil localities, and a discussion of their paleobiology. Many of these groups have never been covered in this fashion before.

Book Description
In the 1930s a band of smart and able young men, some still in their twenties, helped Franklin D. Roosevelt transform an American nation in crisis. They were the junior officers of the New Deal. Thomas G. Corcoran, Benjamin V. Cohen, William O. Douglas, Abe Fortas, and James Rowe helped FDR build the modern Democratic Party into a progressive coalition whose command over power and ideas during the next three decades seemed politically invincible. This is the first book about this group of Rooseveltians and their linkage to Lyndon Johnson's Great Society and the Vietnam War debacle. Michael Janeway grew up inside this world. His father, Eliot Janeway, business editor of Time and a star writer for Fortune and Life magazines, was part of this circle, strategizing and practicing politics as well as reporting on these men. Drawing on his intimate knowledge of events and previously unavailable private letters and other documents, Janeway crafts a riveting account of the exercise of power during the New Deal and its aftermath. He shows how these men were at the nexus of reform impulses at the electoral level with reform thinking in the social sciences and the law and explains how this potent fusion helped build the contemporary American state. Since that time efforts to reinvent government by "brains trust" have largely failed in the U.S. In the last quarter of the twentieth century American politics ceased to function as a blend of broad coalition building and reform agenda setting, rooted in a consensus of belief in the efficacy of modern government. Can a progressive coalition of ideas and power come together again? The Fall of the House of Roosevelt makes such a prospect both alluring and daunting.

Book Description
The Sinap Formation in central Turkey near the city of Ankara preserves a rich record of mammalian evolution from about 15 to 5 million years ago and is one of the few sites in this region that also has fossil apes. It is unique among other fossil localities from Europe to Western Asia in that it has a thick stratigraphic section and preserves a long record of geological time. The authors have been able to piece together a detailed record of faunal change and, by adding paleomagnetic and radiometric dating techniques, have produced a chronostratigraphy for the Formation. Because of the dual importance of the rich record of the fossils, and the dating of the sediments, the editors have been able to attract some of the leading authorities on Eurasian Neogene paleontology and geology to contribute to this reference work. The results from the Sinap Formation will be the template against which other sites from Europe to Asia are compared.

Book Description
In this masterwork, Russell H. Tuttle synthesizes a vast research literature in primate evolution and behavior to explain how apes and humans evolved in relation to one another, and why humans became a bipedal, tool-making, culture-inventing species distinct from other hominoids. Along the way, he refutes the influential theory that men are essentially killer apes—sophisticated but instinctively aggressive and destructive beings. Situating humans in a broad context, Tuttle musters convincing evidence from morphology and recent fossil discoveries to reveal what early primates ate, where they slept, how they learned to walk upright, how brain and hand anatomy evolved simultaneously, and what else happened evolutionarily to cause humans to diverge from their closest relatives. Despite our genomic similarities with bonobos, chimpanzees, and gorillas, humans are unique among primates in occupying a symbolic niche of values and beliefs based on symbolically mediated cognitive processes. Although apes exhibit behaviors that strongly suggest they can think, salient elements of human culture—speech, mating proscriptions, kinship structures, and moral codes—are symbolic systems that are not manifest in ape niches. This encyclopedic volume is both a milestone in primatological research and a critique of what is known and yet to be discovered about human and ape potential.

Book Description
EVOLUTION OF ISLAND MAMMALS Evolution on islands differs in a number of important ways from evolution on mainland areas. Over millions of years of isolation, exceptional and sometimes bizarre mammals evolved on islands, such as pig-sized elephants and hippos, giant rats and gorilla-sized lemurs that would have been formidable to their mainland ancestors. Evolution of Island Mammals, Second Edition, provides an updated and expanded overview of the current knowledge on fossil island mammals worldwide, ranging from the Oligocene to the onset of the Holocene. The book addresses evolutionary processes and key aspects of insular mammal biology, exemplified by a variety of fossil species. Readers familiar with the first edition will find here a host of updated and enhanced material, including: An entirely new chapter on the island rule Updated and expanded theoretical chapters Updated and improved taxonomic information Extensive coverage of new discoveries Body masses or body size indices for most extinct island mammals New figures visualizing the richness of the fossil record This accessible and richly illustrated textbook is written for graduate level students and professional researchers in evolutionary biology, palaeontology, biogeography, zoology, and ecology.

Book Description
The Encyclopedia of Paleontology is designed to address the shortage of general reference works on both vertebrate and invertebrate paleontology and to serve the needs of students and lay persons interested in the field. As the encyclopedia aims to provide basic information, the majority of the 350 entries are devoted to explanations of paleontological concepts and techniques, examinations of the evolutionary development of particular organisms and biological features, profiles of major discoveries, and biographies of leading scientists. Each entry includes an essay and a further reading list. An international team of 200 leading experts in the field has prepared the illustrations and the essays, which range from concise descriptions to comprehensive discussions.
