Plants or animals with identical genomes in a given species can develop into wildly differing forms, depending on environmental conditions, a phenomenon that is widespread in nature yet rarely described in genetic and molecular terms. These authors show that the formation of additional teeth-like structures in the mouth of the nematode Pristionchus pacificus in response to overcrowding is mediated by the same endocrine system that controls dauer larva formation.
