In this work we study a simple evolutionary model of bipartite networks whose evolution is based on the duplication of nodes. Using analytical results along with numerical simulation of the model, we show that the above evolutionary model results in weighted scale-free networks. Indeed we find that in the one-mode picture we have weighted networks with scale-free distributions for interesting quantities like the weights, the degrees and the weighted degrees of the nodes and the weights of the edges.
