1869 C. Darwin Origin of Species (ed. 5) xiii. 515 Professor Häckel in his ‘Generelle Morphologie’..has recently brought his great knowledge and abilities to bear on what he calls phylogeny, or the lines of descent of all organic beings.

1897 Bot. Gaz. 24 172 We are warranted in strenuously urging a conformity of taxonomy with phylogeny.

1901 Trans. Linn. Soc.: Zool. 8 270 The Plates attached to this paper represent with approximate accuracy the phylogeny of the intestinal tract in birds.

1940 J. S. Huxley New Systematics 19 Phylogeny may be almost hopelessly obscured by parallel or convergent evolution.

1953 E. Mayr et al. Methods & Princ. Systematic Zool. iii. 42 It is the avowed aim of a modern classification to reflect phylogeny.

1960 K. Esau Anat. Seed Plants xvi. 215 A well-known concept pertaining to the phylogeny of the form of the vascular system in the axis is that of the stele.

1992 Nat. Hist. Feb. 73/1 An explanation of human brain evolution based on the phylogeny of a general intelligence, as invoked by Falk, just won't do. Any account must describe mechanisms governing the emergence of a specialized language system in the human brain.

1870 G. Rolleston Forms Animal Life p. xxv ‘Phylogenies’, or hypothetical genealogical pedigrees, reaching far out of modern periods, are likely to remain in the very highest degree arbitrary and problematical.

1888 J. W. Dawson Geol. Hist. Plants 269 It is easy to construct a theoretical phylogeny of the derivation of the willows from a supposed ancestral source.

1989 A. J. Jeffreys in J. R. Durant Human Origins iii. 33 When different hominoid phylogenies were examined to see which tree required the least number of site changes.., the most parsimonious tree was found to link man with the African apes, particularly the chimpanzee.

2000 Nature 16 Mar. 214/2 Systematists like Wheeler and Janies view phylogenies as ‘unrooted’ networks. ‘Rooting’ the network to a putative common ancestor, producing the familiar textbook evolutionary tree, comes later.
