When many scholars are asked about early human settlement in the Americas, they might point to a handful of archaeological sites as evidence. Yet the process was not a simple one, and today there is no consistent argument favoring a particular scenario for the peopling of the New World. This book approaches the human settlement of the Americas from a biogeographical perspective in order to provide a better understanding of the mechanisms and consequences of this unique event. It considers many of the questions that continue to surround the peopling of the Western Hemisphere, focusing not on sites, dates, and artifacts but rather on theories and models that attempt to explain how the colonization occurred. Unlike other studies, this book draws on a wide range of disciplines—archaeology, human genetics and osteology, linguistics, ethnology, and ecology—to present the big picture of this migration. Its wide-ranging content considers who the Pleistocene settlers were and where they came from, their likely routes of migration, and the ecological role of these pioneers and the consequences of colonization. Comprehensive in both geographic and topical coverage, the contributions include an explanation of how the first inhabitants could have spread across North America within several centuries, the most comprehensive review of new mitochondrial DNA and Y-chromosome data relating to the colonization, and a critique of recent linguistic theories. Although the authors lean toward a conservative rather than an extreme chronology, this volume goes beyond the simplistic emphasis on dating that has dominated the debate so far to a concern with late Pleistocene forager adaptations and how foragers may have coped with a wide range of environmental and ecological factors. It offers researchers in this exciting field the most complete summary of current knowledge and provides non-specialists and general readers with new answers to the questions surrounding the origins of the first Americans.
For anyone interested in recent American research on climate, cities, Geographical Information Systems, Latin America, or any of the other subfields in geography, this volume provides representative accounts of American geographers' contributions in 47 specialty areas. This wide range of specialties comprises both a comprehensive reference and a 'state of the discipline' report. - ;Geography in America at the Dawn of the 21st Century surveys American geographers' current research in their specialty areas and tracks trends and innovations in the many subfields of geography. As such, it is both a 'state of the discipline' assessment and a topical reference. It includes an introduction by the editors and 47 chapters, each on a specific specialty. The authors of each chapter were chosen by their specialty group of the American Association of Geographers (AAG). Based on a process of review and revision, the chapters in this volume have become truly representative of the recent scholarship of American geographers. While it focuses on work since 1990, it additionally includes related prior work and work by non-American geographers. The initial Geography in America was published in 1989 and has become a benchmark reference of American geographical research during the 1980s. This latest volume is completely new and features a Foreward written by the eminent geographer, Gilbert White. - ;"This comprehensive work provides an opportunity for all to share an understanding of what professional geography in the US has become. Highly recommended." Geoffrey J. Martin, Choice -
