A model, presented in Chapter 7, tentatively explains how random mutations can lead not only to cancer, but also to reduced function of the highly differentiated cells in vertebrates. Aging would then be the result of the ultimate failure of genome maintenance in preventing increased noise in the execution of various cellular programs due to accumulating errors in the information content of the genome. However, this model remains untested and could be wrong. Instead, aging could be partially or wholly due to a combination of other processes, most notably increased damage to cellular macromolecules, which may not be restricted to DNA, and the responses to their adverse effects. This chapter discusses the consequences of a scenario in which aging is predominantly a result of random, irreversible alterations in the somatic genome, and how that would impact our prospects to intervene and possibly retard or reverse aging-related cellular degeneration and organismal death.
