There are many possible links between pattern(s) and mechanism(s), depending on whether one or more pattern(s) and mechanism(s) are considered: (a) a novel link between one mechanism and one pattern, (b) the robustness of one mechanism leading to multiple patterns, (c) a relative importance of multiple mechanisms for one pattern, (d) the reconciliation of multiple patterns with one mechanism, and (e) the interaction among multiple mechanisms to generate multiple patterns.
