The idea of this review is to connect the different models of evolution to
those of biological ageing through Darwin's theory. We start with the Eigen
model of quasispecies for microevolution, then introduce the Bak-Sneppen m
odel for macroevolution and, finally, present the Penna model for biologica
l ageing and some of its most important results. We also explore the concep
t of coevolution using this model. (C) 2000 Elsevier Science B.V. All right
