Origin: A borrowing from German. Etymon: German Ontogenesis.

Etymology: < German Ontogenesis (Haeckel Gen. Morphol. der Organismen (1866) I. 55) < onto- onto- comb. form + Genesis genesis n. Compare French ontogénèse (1874). Compare earlier ontogeny n., ontogenetic adj., ontogenetically adv.

Biology.

The development of the individual organism from the earliest embryonic stage to maturity. Also: the development of a particular (anatomical, behavioural, etc.) feature of an organism. Cf. phylogenesis n.
