From: Directional selection coupled with kin selection favors the establishment of senescence
Quantitative aspects of evolving senescence across the model simulations. The lattice average of A rate of aging \((\overline{\alpha })\), B age of individuals \((\overline{\tau })\), C mortality \((\overline{\delta })\), D normalized fecundity \((\overline{\varphi })\), E Pearson correlations between fecundity and rate of aging as functions of time. F Age distribution of populations at \(t=6000\) under directional selection (left panel) and stabilizing selection (right panel). Blue: directional selection; red: stabilizing selection. Darker shades represent sexual populations, lighter shades show the corresponding asexual cases. Parameters are as in Table 1
