Evolution of reaction norms in slow coarse-grained environments with low mutation rates.

(A) Lack of fit (see Evaluation of reaction norms) in current (green lines) and past (blue lines) environments. Orange lines indicate realized (solid lines) and optimal (dashed lines) adaptive plasticity. (B) Evolved reaction norms (grey lines) compared to optimal reaction norm (dashed line) at the end of the evolutionary period. Crosses indicate optima corresponding to environmental values used in the simulation. Dots indicate the phenotypes expressed for those values. The population slowly evolves optimal adaptive plasticity.
