Abstract
Although the basic theories concerning evolution of senescence have been generally accepted for a half-century, interpretation of this paradigm has been constrained by an over-reliance on mortality as both the cause and the measure of senescence. Consideration of both survival and fecundity as components of reproductive value, and integration of sexual selection theory with senescence theory allows reconciliation of long-standing, as well as recent, discrepancies between data and theory. This approach demonstrates that sexual selection on males in polygynous mating systems can have significant effects on the evolution of senescence that could overshadow the selection effects of mortality rates among such animals.
