'''Structural inheritance''' or '''cortical inheritance''' is the transmission of an [[epigenetics\|epigenetic]] trait in a living [[organism]] by a self-perpetuating spatial structures. This is in contrast to the transmission of digital information such as is found in [[DNA]] sequences, which accounts for the vast majority of known [[genetics\|genetic]] variation.

	Examples of structural inheritance include the propagation of [[prion]]s, the infectious proteins of diseases such as [[scrapie]] (in sheep and goats), [[bovine spongiform encephalopathy]] ('mad cow disease') and [[Creutzfeldt–Jakob disease]] (although the protein-only hypothesis of prion transmission has been considered contentious until recently).<ref name="pmid15272271">{{cite journal \|vauthors=Soto C, Castilla J \| title = The controversial protein-only hypothesis of prion propagation \| journal = Nat.
