Before revision:  When comparing E. coli and Mycoplasma pneumoniae, we find that the metabolic networks of the URLanisms exhibit opposite relationships between the relative importance of plasticity and redundancy , consistent with the conjecture that plasticity is a more sophisticated mechanism that requires a more URLanization.
After revision:  When comparing E. coli and Mycoplasma pneumoniae, we find that the metabolic networks of the URLanisms exhibit a large difference in the relative importance of plasticity and redundancy , consistent with the conjecture that plasticity is a more sophisticated mechanism that requires a more URLanization.
