Effects of fitness epoch length and local neighborhood radius on the rate of aging. A Evolution of the lattice average of rate of aging (\(\overline{\alpha }\)) as a function of the fitness period dilution (\(T\)). Average of 100 runs; standard deviations within the range where aging can evolve are negligibly small (on the order of \({10}^{-3})\). Other parameters are as in Table 1. B The lattice average of rate of aging (\(\overline{\alpha }\)) as a function of time for different neighborhood radii (\(n\)) assuming a sexual population. Note that the value of n is inconsequential under the stabilizing selection regime. Other parameters are as in Table 1
