I find that somewhat strange. Why attribute the idea of introducing new nodes to a graph to biological concepts? It seems like a simple step in exploration, similar to how one might think to vary the weights of the nodes randomly over some range.. unless there is some technique biology uses to pre-configure the nodes upon introduction to the network, that might be rather interesting.
