Ontogeny (also ontogenesis or morphogenesis) describes the origin and the development of an organism from the fertilizedegg to its mature form. Ontogeny is studied in developmental biology. Morphogenesis is also the name of a band. ... This article or section does not adequately cite its references or sources. ... Categories: Biology stubs ... A human ovum Sperm cells attempting to fertilize an ovum An ovum (plural ova) is a haploid female reproductive cell or gamete. ... Sexual maturity is the stage at which an organism can reproduce. ...

Ontogeny is better 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).
The theory of recapitulation, also called the biogenetic law or ontogeny recapitulates phylogeny, is a theory in biology which attempts to explain apparent similarities between humans and other animals. ... In biology, phylogenetics (Greek: phylon = tribe, race and genetikos = relative to birth, from genesis = birth) is the study of evolutionary relatedness among various groups of organisms (e. ...

A final area to briefly mention is ontogenetics changes in physiological traits of invertebrates.
We have focused previously on the ontogeny of osmoregulatory capacities in estuarine shrimp and the timing of diapause in sponge gemmules.
The ontogenetic acquisition of hypoxia tolerance is a key issue that deserves more exploration in marine invertebrates inhabiting oxygen limited environments.
Being phylo-"genetic" they would constitute a transcendental (always already) "origin" prior to any ontogenetic origin, including the "original experience of satisfaction," which inaugurates the primal process and the pleasure principle through its binding of the perceptual identity.
Again, this perceptual identity constitutes a tendency or aim of whatever mobility follows its establishment as the basis of the primary process and pleasure principle; thus this mobility is not free.
The traumas of the sexual "scenes" of primal phantasies–primarily castration, but also the primal scene and seduction–would unfold during the first five or so years of life in an ontogenetic version of the trials of the primaeval son, which ends in either the resolution or non-resolution of the Oedipus complex.
