Fit of the evolutionary trajectories to the null model, the single-ecotype model and the multi-ecotype model. Panels (aj) Correspond to replicate communities A–J, respectively. The observed trajectory and the expected trajectory for the best-fitting model in each case are shown by solid and dashed lines, respectively. The trajectory of community A was best fit to the null model (green). The trajectories of communities C and J were best fit to the single-ecotype model (red). The trajectories of the remaining communities were best fit to the multi-ecotype model (blue).
