Before revision: Though the problem of pattern formation in biological systems has been studied for more than sixty years, it is from the beginning of this century that the synergy between theoretical and experimental researchers are depicting the ins and outs of this problem .
After revision: URLanogenesis, developmental programs governed by Gene Regulatory Networks (GRN) define the functionality, size and shape of the different constituents of URLanisms. Robustness, thus, is an essential characteristic that GRNs need to fulfill in order to maintain viability and reproducibility in a species .
