Book Description
Land bridges are the causeways of biodiversity. When they form, organisms are introduced into a new patchwork of species and habitats, forever altering the ecosystems into which they flow; and when land bridges disappear or fracture, organisms are separated into reproductively isolated populations that can evolve independently. More than this, land bridges play a role in determining global climates through changes to moisture and heat transport and are also essential factors in the development of biogeographic patterns across geographically remote regions. In this book, paleobotanist Alan Graham traces the formation and disruption of key New World land bridges and describes the biotic, climatic, and biogeographic ramifications of these land masses’ changing formations over time. Looking at five land bridges, he explores their present geographic setting and climate, modern vegetation, indigenous peoples (with special attention to their impact on past and present vegetation), and geologic history. From the great Panamanian isthmus to the boreal connections across the North Atlantic and North Pacific Oceans that allowed exchange of organisms between North America, Europe, and Asia, Graham’s sweeping, one-hundred-million-year history offers new insight into the forces that shaped the life and land of the New World.

Book Description
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.

Book Description
It is now well known that the concept of drifting continents became an estab lished theory during the 1960s. Not long after this "revolution in the earth sciences," researchers began applying the continental drift model to problems in historical biogeography. One such problem was the origin and dispersal of the New World monkeys, the Platyrrhini. Our interests in this subject began in the late 1960s on different conti nents quite independent of one another in the cities of Florence, Italy, and Berkeley, California. In Florence in 1968, A. B. Chiarelli, through stimulating discussions with R. von Koenigswald and B. de Boer, became intrigued with the possibility that a repositioning of the continents of Africa and South America in the early Cenozoic might alter previous traditional conceptions of a North American origin of the Platyrrhini. During the early 1970s this con cept was expanded and pursued by him through discussions with students while serving as visiting professor at the University of Toronto. By this time, publication of the Journal of Human Evolution was well underway, and Dr. Chiarelli as editor encouraged a dialogue emphasizing continental drift models of primate origins which culminated in a series of articles published in that journal during 1974-75. In early 1970, while attending the University of California at Berkeley, R. L. Ciochon was introduced to the concept of continental drift and plate tectonics and their concomitant applications to vertebrate evolution through talks with paleontologist W. A. Clemens and anthropologist S. L. Washburn.

Book Description
The discovery in the 1920s of a huge cache of fossils in the Gobi Desert fuelled a mania for dinosaurs that continues to the present. But the original goal of the expedition was to search for the origins of man. Henry Fairfield Osborn (1857-1935), director of the American Museum of Natural History, stood at the forefront of the debate over human evolution and the expedition aimed to prove his theory of human origins. Osborn rejected the idea of primate ancestry and constructed a non-Darwinian theory that the evolution of man was the long adventurous story of individuals and groups exerting personal will-power and inborn characteristics to achieve both biological and spiritual success. It is an idea that still echoes today. Study of Osborn’s thinking, however, has been obscured by the perception that racism influenced his theories. Brian Regal paints a different and more textured picture in this book - he shows that Osborn's views on race, like his political ideas, were motivated by his science, itself grounded in religious doctrine. His belief in the Central Asian origins of man, his role as an activist for eugenic reform and immigration controls, his support for Nordicism, his place in the 'New' versus 'Old' biology debate, his role in the Christian Fundamentalist controversy, the Scopes Monkey trial, and finally his construction of the 'Dawn Man' hypothesis - all stemmed from his desire to support his human evolution theory, and point the way to salvation. This biography charts Osborn's intellectual development, from its roots in the eclectic Christianity of his mother, through his student days with Arnold Guyot, James McCosh, and T.H. Huxley, to his mature work at the American Museum. It examines his trials and tribulations, friendships and conflicts, and the world in which he lived: all contributed to the construction of his theory. It is the dramatic story of a man holding onto ideas that for him represented the very meaning of life itself.

Book Description
Human Evolutionary Genetics is a groundbreaking text which for the first time brings together molecular genetics and genomics to the study of the origins and movements of human populations. Starting with an overview of molecular genomics for the non-specialist (which can be a useful review for those with a more genetic background), the book shows how data from the post-genomic era can be used to examine human origins and the human colonization of the planet, richly illustrated with genetic trees and global maps. For the first time in a textbook, the authors outline how genetic data and the understanding of our origins which emerges, can be applied to contemporary population analyses, including genealogies, forensics and medicine.
