Generic features of biological pattern-forming systems have been uncovered that promote robustness with respect to variations between different cells or populations in system components, such as protein production rates and gene-regulatory network architecture. By contrast, less is understood about how such systems respond to spatio-temporal changes in morphogen concentrations within individual cells or populations over timescales faster than or similar to growth. Here, we formulate and apply a general theory of biological pattern formation in spatio-temporally varying concentrations of “pre-patterning” morphogens, which determine system parameters. Our analytical results reveal universal dynamical regimes of biological pattern-forming systems, and quantify how the dynamics in each regime depend on the mathematical properties of the relevant gene-regulatory network. By applying our theory, we predict that two paradigmatic pattern-forming systems are robust with respect to spatio-temporal morphogen variations that happen faster than growth timescales. More broadly, we predict that the dynamics of pattern-forming systems with spatio-temporally varying parameters can be classified based on the bifurcations in their governing equations.
