Read a collection of science essays, the last one
was about epigenetics

parking a few quotes

Epigenetic features may play a role in short-term adaptation of species by allowing for reversible phenotype variability.
en.wikipedia.org

Epigenetic multistability may be vital to cells that are outwardly different, but genetically identical. Only one of the two phenotypes might thrive in a given environmental condition; however, the less advantageous phenotype could come in handy if the environmental conditions unexpectedly changed. By having both phenotypes, the chances would be better that the best one will be present when needed.
