As environments change, selective pressures shift and favor different adaptations. The theory of facilitated variation is supported by computational analyses of the evolution of regulatory networks. These studies confirm that phenotypic variability can be directed towards phenotypes with high fitness even when mutations are randomly distributed, and even when challenged with novel environmental conditions.
