Population dynamics in a spin-glass model of chemical evolution.
Journal - Journal of molecular evolution (UNITED STATES )
We introduce a simple model describing the evolution of a population of information-carrying macromolecules. We discuss the asymptotic dependence of the variability of the population on different parameters, representing the severity or the fluctuations of the environment. We show the existence of a transition separating a neutralist evolutionary regime from a trapped one. We investigate the dependence of the evolutionary behavior of the population on the correlation properties of the fitness landscape.

[Neutralism and adaptation in a simple model of molecular evolution]
Journal - Comptes rendus de l'Académie des sciences. Série III, Sciences de la vie (FRANCE )
We introduce a simple model of molecular evolution, with a fixed population and a rugged fitness function. We exhibit the analogy between the crossover from a neutralist to an adaptative evolutionary behavior and the percolation transition in genome space.
