Evolution of the rate of biological aging using a phenotype
... A rather obscure model for the evolution of aging is the Heumann-Hotzel model (Heumann and Hotzel, 1995), which is a generalization of the Dasgupta model (Dasgupta, 1994). In this model, each individual carries a ”chronological genome” of size xmax , with a survival probability per time step G(x) at ...
