Abstract

Humans, and many other species, suffer senescence: mortality increases and fertility decreases with adult age. Some species, however, enjoy sustenance: mortality and fertility remain constant. Here we develop simple but general evolutionary-demographic models to explain the conditions that favor senescence vs. sustenance. The models illustrate how mathematical demography can deepen understanding of the evolution of aging. © 2010 Annette Baudisch & James W. Vaupel.
