Abstract
This payer discusses some aspect of the dynamical evolution of the sys tem described by Dyson's model for the origin of metabolism. First, th e mean number of mutation events required to observe the origin of met abolism in the model is calculated. This number can span a large range depending upon the values of some critical parameters. Second, the dy namics of the relaxation to equilibrium is investigated by computing t he correlation function of an on-off random function that defines the instantaneous state of the system. It was found that the dynamics of t he system is well described by a double or a stretched exponential rel axation.
