Simulations for the non-conservative model with random initial conditions $u=u_{\ast }(1+\text{Unif}(-0.01,+0.01)),v=v_{\ast }$ with default parameters from Table 4 (NC) except $\gamma =25$. The color range is chosen so that the precursor pattern is more visible. The rapid transition from the shallower, higher frequency precursor pattern to the final pattern can be clearly seen
