1906 O. F. Cook in Science 30 Mar. 506/2 Speciation..is the origination or multiplication of species by subdivision, usually..as a result of environmental incidents.

1907 O. F. Cook in Proc. Wash. Acad. Sci. 8 278 Speciation is the attainment of differential characters by segregated groups of organisms, that is, by subdivisions of older species.

1944 G. G. Simpson Tempo & Mode in Evolution vii. 203 The pertinent data of paleontology fall into patterns of the phyletic mode. It has naturally resulted that paleontologists have overemphasized this mode..just as most experimentalists have overemphasized and overgeneralized from the speciational mode.

1983 W. C. Kimler in M. Grene Dimensions of Darwinism v. 125 The creaking of the synthesis at present around its adaptationist and speciational ideas is perhaps to be expected as the result of a fresh ecological input.

1988 E. Mayr Toward New Philos. of Biol. xxvi. 483 It has been shown that ‘speciational evolution’ (perhaps a better term than punctuationism) is fully consistent with Darwinism.

1989 Cladistics V. 58 Speciational evolution, via punctuational change, is at least a viable explanation for the distribution of allozyme character change found among species of lizards in the genus Sceloporus.
