Definitions

  • WordNet 3.6
    • n ontogeny (biology) the process of an individual organism growing organically; a purely biological unfolding of events involved in an organism changing gradually from a simple to a more complex level "he proposed an indicator of osseous development in children"

Webster's Revised Unabridged Dictionary
    • n Ontogeny (Biol) The history of the individual development of an organism; the sequence of events involved in the development of an organism; the history of the evolution of the germ; the development of an individual organism, -- in distinction from phylogeny, or evolution of the tribe. Called also henogenesis henogeny.

    • n ontogeny Specifically or specially, the ontogenesis of an individual living organism; the entire development and metamorphosis or life-history of a given organism, as distinguished from phylogeny.

Evaluating Intraspecific Variation and Interspecific Diversity: comparing humans and fish species
Raff and Sly pointed out that modularity enables the evolution of ontogeny because it makes three processes possible: the dissociation of developmental processes (e.g. heterochrony), the duplication and subsequent divergence of developmental modules, and the co-option of features into new functions .
