Simulation results for
and
. For each small panel, the environmental cue is on the x-axis and phenotype on the y-axis. Each reaction norm is the population mean for one replicate simulation, and 100 replicates were performed for each combination of P and R. Red color shows reaction norms, where the population evolved reversible plasticity (
or
, and
). Orange color shows reaction norms where reversible and anticipatory effects evolved (in addition
), blue color indicates that only developmental plasticity evolved (
or
, and
), purple color indicates that both developmental plasticity and anticipatory effects evolved (in addition
), green color indicates that increased developmental variation evolved (
), and black color indicates that there was no major change in reaction norm slope (
). Note the logarithmic scale for R.
