Before revision:  We study stability properties of a generic gene regulatory network (GRN) and demonstrate that phenomenology of ageing and the associated population mortality rate can be naturally described in terms of critical dynamics of gene regulation and metabolic profiles.
After revision:  To address this question, we examine stability properties of a generic gene regulatory network (GRN) and demonstrate that phenomenology of ageing and the associated population mortality rate can be naturally described in terms of critical dynamics of gene regulation and metabolic profiles.
