This book explores how and why prehistoric Southwestern societies changed in complexity, and offers important new perspectives on evolution of culture. It discusses the factors that made prehistoric Southwesterners vulnerable to an arid environment, and their strategies to lessen risk and stress.

Cultural behavior exhibits many of the features of complex adaptive systems, but is in some ways distinctive. Cultural complexity is enigmatic, improbable, and difficult to maintain. It constrains behavior, limits understanding of processes, and imposes economic burdens. The advantages of complexity are modified by human cognition and limited by economic and environmental costs. This book explores in detail how and why prehistoric Southwestern societies changed in complexity, and thus offers important new perspectives on the evolution of culture.The papers discuss the factors that made prehistoric Southwesterners vulnerable to an arid environment, and their strategies to lessen risk and stress. The topics of the book link Southwestern data to fields such as economics, climatology, and evolutionary theory. In addition to a readership of archaeologists and anthropologists, this volume will be of interest to specialists in these related fields and to those concerned with complex adaptive systems and the work of the Santa Fe Institute.

Assuming that the complex phenomena underlying the operation of the immune system may be better understood through the collaborative efforts of theorists and experimentalists viewing the same phenomena in different ways, the Sante Fe Institute and the Theoretical Division of Los Alamos National Laboratory cosponsored a workshop entitled "Theoretical Immunology." The workshop focused on themes spanning the field of immunology, with emphasis on areas where the theorists have made the most progress. This book covers the discussions a that workshop on the topics of immune surveillance, mathematical models of HIV infection, complexities of antigen-antibody systems, immune suppression and tolerance, and idiotypie networks. In each of these areas there is reason to believe that advances can be made either through interactions among experimentalists and theorists or through the critical look experimentalists and theorists will bring to bear upon one another's work.

This book discusses the emergence of life, the development of the individual, and the study of the interaction between individuals and species. It gives the student of theoretical biology some idea of the flavor of current research in the field.

Research on hunting and gathering peoples has given anthropologists a long-standing conceptual framework of sedentism and mobility based on seasonality and ecological constraints. This work challenges that position by arguing that mobility is a socially negotiated activity and that neither mobility nor sedentism can be understood outside of its social context. Drawing on research in the Mesa Verde region that focuses on communities and households, Mark Varien expands the social, spatial, and temporal scales of archaeological analysis to propose a new model for population movement. Rather than viewing sedentism and mobility as opposing concepts, he demonstrates that they were separate strategies that were simultaneously employed. Households moved relatively frequently--every one or two generations--but communities persisted in the same location for much longer. Varien shows that individuals and households negotiated their movements in a social landscape structured by these permanent communities. Varien's research clearly demonstrates the need to view agriculturalists from a perspective that differs from the hunter-gatherer model. This innovative study shows why current explanations for site abandonment cannot by themselves account for residential mobility and offers valuable insights into the archaeology of small-scale agriculture.

Sustainable Lifeways addresses forces of conservatism and innovation in societies dependent on the exploitation of aquatic and other wild resources, agriculture, and specialized pastoralism. The volume gathers specialists working in four areas of the world with significant archaeological and paleoenvironmental databases: West Asia, the American Southwest, East Africa, and Andean South America, and contributing to research in three broad time scales: long term (spanning millennia), medium term (archaeological time, spanning centuries or a few thousand years), and recent (ethnohistoric or ethnographic, spanning years or decades). By bringing an archaeological eye to an examination of human response to unpredictable environmental conditions, informed by an understanding of contemporary traditional peoples, the contributors to this volume develop a more detailed picture of how societies perceive environmental risk, how they alter their behavior in the face of changing conditions, and under what challenges the most rapid and far-reaching changes in adaptation have taken place. Sustainable Lifeways enhances our understanding of both the forces of conservatism and innovation which may have been in play in major transitions in the past, such as the development of complex society, and the expansions of early empires. Studies present examples of cattle herders in East Africa, hunter-gatherers and pastoralists in the Levant, South American fisher/farmers, and farmer/hunters of the U.S. Southwest.

This comprehensive, fully illustrated Companion answers the need for an in-depth archaeology reference that provides authoritative coverage of this complex and interdisciplinary field. The work brings together the myriad strands and the great temporal and spatial breadth of the field into two thematically organized volumes. In twenty-six authoritative and clearly-written essays, this Companion explores the origins, aims, methods and problems of archaeology. Each essay is written by a scholar of international standing and illustrations complement the text.
