progenesisn.

Brit.

/prə(ʊ)ˈdʒɛnᵻsɪs/, U.S.

/proʊˈdʒɛnəsəs/

Origin: Formed within English, by derivation; modelled on a French lexical item. Etymons: pro- prefix², -genesis comb. form.

Etymology: < pro- prefix² + -genesis comb. form, after French progénèse (A. Giard & J. Bonnier 1887, in Travaux de l'Inst. Zool. de Lille et du Laboratoire de Zool. Maritime de Wimereux 5 ii. 195).

Biology.

Precocious sexual maturity in an organism still in a larval (or other immature) stage (= paedogenesis n. 2); (also) accelerated maturation of the sexual organs (as an evolutionary process) resulting in paedomorphosis (cf. neoteny n.).
