This web site is dedicated to providing information and resources about theories of biological aging.

There are two main aging concepts as applied to humans and most other mammals. The programmed aging theories, also known as adaptive or active aging theories, propose that mammals purposely deteriorate with age because a limited life span provides evolutionary benefits. Non-programmed theories, also known as passive or non-adaptive theories, contend that a limited life span is entirely adverse and that aging is not genetically programmed for the purpose of causing deterioration or death.

Programmed theories provide a better match to observations, but are based on newer concepts regarding evolution mechanisms. Non-programmed theories have difficulty explaining many observations but are compatible with older evolutionary mechanics concepts.

This issue is important because most people in developed countries now die of age-related diseases. Understanding, preventing, and treating these diseases requires that we understand the aging process.

In addition to introductory and educational material, this site provides extensive descriptions of the various programmed and non-programmed theories and access to full-text or abstracts of many journal articles.
