Evolutionary model. (a) Scheme of the basic moves. A domain of a given class (represented by its color) is duplicated with probability p N , giving rise to a new member of the same family (hence filled with the same color). Alternatively, an innovation move creates a domain belonging to a new domain class (new color) with probability p N . (b) Summary of the main mathematical quantities and parameters of the model.
