Aging, like all biological characters, evolves. From an evolutionary point of view, it can be defined as a sustained age-specific decline of fitness-related characteristics that is not due to external environmental factors. This chapter discusses the evolutionary theories of aging and the experimental studies that have tested and challenged them, and also discusses the postaging phase of life, referred to as “late life,” and the experimental and theoretical work surrounding this phenomenon.

Keywords:   aging, age-specific decline, evolutionary theories, late life
