Before revision:  For such networks, convergence to an adapted phenotype can be achieved without fine tuning of initial conditions or other model parameters, thus making it plausible for biological implementation  .
After revision:  For such networks, convergence to an adapted phenotype can be achieved without fine tuning of initial conditions or other model parameters, thus making it plausible for biological implementation . Experimental results have indeed shown that gene regulatory networks are characterized by this type of topology, suggesting a structural basis for exploratory adaptation .
