Ontogeny 22469 222685359 2008-06-30T16:43:47Z 128.91.137.141 '''Ontogeny''' (also ontogenesis or [[morphogenesis]])('''''ontos''''' present participle of 'to be', '''''genesis''''' 'creation') describes the origin and the development of an [[organism]] from the [[fertilize|fertilized]] [[Ovum|egg]] to its [[mature]] form. Ontogeny is studied in [[developmental biology]], [[developmental psychology]], and [[developmental psychobiology]]. In more general terms, '''ontogeny''' is defined as the history of structural change in a unity, which can be a cell, an organism, or a society of organisms, without the loss of the organization that allows that unity to exist (Maturana and Varela, 1987, p. 74). ==See also== {{Wiktionary}} * [[Recapitulation theory]], the idea that ontogeny recapitulates [[phylogeny]] * [[List_of_publications_in_biology#Ontogeny| Important publications in ontogeny]] ==References== * Maturana, H.
