Here, I deal with the general nature and significance of epigeny. Then, some fundamental mechanisms operating during the epigenetic process are considered. The core of this chapter is represented by the analysis of the steps of epigeny (especially embryogenesis and organogenesis will be considered). A specific but very relevant aspect is the way in which the brain develops and how a functional organization of the brain is superposed to a developmentally previous one having a simple structural character. Another important issue is the significance of the Waddington effect, one of the first phenomena to have attracted the attention of scholars to this field. Finally, the relations between phylogeny, ontogeny, and epigeny are framed in a wider synthesis.

Keywords: epigeny; embryogenesis; organogenesis; Waddington effect; hierarchy; teleonomy; teleology
