Tóm tắt

Since the 1990s, laboratory characterization of aging has been diverging from predictions of evolutionary theory, especially in the area of genetics. Concurrently, a science of multilevel selection has found its place in the evolutionary literature. The author suggests that evidence warrants consideration of a new paradigm for evolution of aging, and proposes the demographic theory of senescence, whereby aging has been affirmatively selected because it levels the death rate over time, helping to stabilize population dynamics and prevent extinctions.
