Brit. |ˌhɒləʊfʌɪˈlɛtɪk|, U.S. |ˈˌhɑloʊˌfaɪˈlɛdɪk|
[‹ holo- comb. form + phyletic adj. Compare earlier monophyletic adj., paraphyletic adj.]
Of a group or taxon: including all and only the descendants of a common ancestor or ancestral group; monophyletic (in the narrower sense). Cf. paraphyletic adj.
1971P. D. Ashlock in Systematic Zool. 20 67 The criterion for monophyly proposed here sounds similar to Hennig's principle, which can be stated as follows: only synapomorphous characters delimit monophyletic (herein called holophyletic) groups. 1989Nature 26 Jan. 382/1 All the currently available data indicate that cyanobacteria, prochlorophytes, and chloroplasts constitute a ‘holophyletic’ group. 1996Evolution 50 2/2, I follow Ashlock in referring to..a monophyletic group as either holophyletic or paraphyletic. |
