It is often claimed that biological networks are particularly robust or modular, or have remarkable features such as being scale free. To separate consequences of evolutionary dynamics from constraints due to functionality, we first construct a microscopic model of the genotype to phenotype map which then specifies the effects of these constraints. Given such a framework, we show how Monte Carlo sampling reveals the exceptionality or not of different biological networks. Illustrations will be given for gene networks and metabolic networks.
