Investigators have long recognized the importance of certain elements, commonly called "minerals," in the diet of humans and animals and in the soil that supports plants, in that these elements are essential for the life or optimum health of the organisms. Deficiencies of 20 to 24 elements in animals and man and of 13 to 18 elements in plants have been recognized. At the same time, an understanding of the responses of these organisms to the insult of toxic concentrations of these and other elements also has been of interest. More recently, concern has arisen regarding the effects of an organism's exposure to the more subtle chronic and subchronic concentrations of certain elements that industrial and other human activities are releasing into the environment.

California Archaeology provides a compilation of knowledge for archeologists who are not California specialists. This book explains important cultural events and patterns discovered archeologically. Organized into 11 chapters, this book begins with an overview of California's historic and ancient environments as well as the evidence of Pleistocene human activity. This text then examines the glacial and other environmental conditions that would have influenced the origins, adaptations, and spread of the earliest North Americans. Other chapters consider how California's past is relevant to a wider understanding of human behavior. This book discusses as well the perceptions of Central Coast and San Francisco Bay region prehistory that have changed rapidly as a result of intensive fieldwork performed to comply with environmental law. The final chapter deals with the data of historical linguistics, which indicate something of the cultural relationships and events that might have occurred in the past. This book is a valuable resource for archeologists.

Some forty scholars examine California's prehistory and archaeology, looking at marine and terrestrial palaeoenvironments, initial human colonization, linguistic prehistory, early forms of exchange, mitochondrial DNA studies, and rock art. This work is the most extensive study of California's prehistory undertaken in the past 20 years. An essential resource for any scholar of California prehistory and archaeology!
