1884 Amer. Naturalist 18 434 The extremity of the tail [of the lizard Hatteria punctata] was in neogenesis.

1903 Ibis 3 15 But the opposite hypothesis, that we have in this singular small Owl a case of neogenesis—i.e. the ex-abrupto formation of a new type with sufficient differential characters to constitute, if maintained, a new species,—can, I believe, be upheld. The term neogenesis was first used to explain this sudden origin of new forms from old-established species..by my friend and colleague Prof. Paolo Mantegazza, many years ago; it has been since used, more or less in the same sense, by the late Prof. Cope and by others.

1936 New Phytologist 35 488 He does not take into account the possible manifestation of neogeneses in ontogeny and their prevalence in plants.

1946 Nature 10 Aug. 202/1 The situation is essentially different in coma, in the sense that although neogenesis of sugar occurs (high blood sugar during fast) storage of glycogen in the liver is no longer possible.

1972 Gloss. Geol. (Amer. Geol. Inst.) 477/1 Neogenesis, the formation of new minerals, as by diagenesis or metamorphism.

1998 Proc. National Acad. Sci. U.S.A. 95 14517 Granule cell neogenesis occurs well into adulthood in a manner regulated by environmental demands.
