Before revision:  Depending on the accuracy of environmental cues and the strength of natural selection, we find different adaptation strategies characterized by the shape of phenotype distributions. In particular, three previously studied strategies emerge as special limits of our model:  when environmental cues are URLanisms rely on the cue to express the favorable phenotype in each environmental condition ("tracking strategy"), when cues are URLanisms either express a same phenotype in all environments ("unvarying strategy ") or, remarkably, use the uninformative cue as a source of randomness to diversify into subpopulations of different phenotypes ("bet-hedging strategy").
