Explicatio terminorum

Epigenetics, in biology, and specifically genetics, epigenetics is the study of changes in gene expression or cellular phenotype, caused by mechanisms other than changes in the underlying DNA sequence – hence the name epi- (Greek: επί- over, above, outer) -genetics, some of which are heritable.

Systema Naturae  was one of the major works of the Swedish botanist, zoologist and physician Carolus Linnaeus and introduced the Linnaean taxonomy.

Taxonomy  (from ancient Greek τάξις taxis, arrangement, and νομία nomia, method) is the academic discipline of defining groups of biological organisms on the basis of shared characteristics and giving names to those groups.
