A multiple-integral equation, termed the wearout equation, describes the distribution of wearout (or aging) over evolved reliability structures, such as organisms and self-replicating machines, and thus statistically governs virtually all aging properties of the systems. The equation is applied to the computation of ab initio ("from the beginning") life tables for four natural populations of ungulates--wild boar, Dall sheep, African buffalo, and hippopotamus--which represent a broad range of survival characteristics. The good agreement of the ab initio and empirical tables, the best available for testing the theory, demonstrates the basic realism of the wearout equation. If the equation withstands further experimental testing, its analysis may provide insight into fundamental questions in the biology of aging.
