Presenting the latest research in the biology of aging, this volume addresses important theoretical issues focusing on the basis for why humans live as long as they do. Expert authors combine three general paradigms of aging research: demographic studies, evolutionary studies, and studies of biological mechanisms.

Topics explored include:

• Why does aging occur?
• Cellular aging
• Models in aging research
• Modern approaches to the mechanisms of aging
• The genetics of behavioral aging

This volume presents a clear, concise overview of the current state of knowledge about the biology of aging - serving as both an invaluable graduate-level text and a key reference for practicing professionals. Over a dozen distinguished contributors probe the latest developments in our knowledge of why people age and how the process works. These authoritative chapters are not just written for biologists - but for gerontologists in general. Marks the tenth anniversary of the Annual Review of Gerontology and Geriatrics.
