Soc. 135 3 Following a suggestion made by Mr. H. K. Pusey, we shall refer to the arrangement by overall similarity, based on all available characters without any weighting as phenetic, since it employs all observable characters (including of course genetic data when available). 1971 Virology 45 357/2 To be useful, a classification of viruses..must be based on many characters, not few... This will give a classification based on the general resemblance of the phenotypic characters of the viruses (a ‘phenetic classification’). 1989 Nature 18 May 189/3 The phenetic resemblances of this hypodigm to H[omo] habilis are recognized. 2000 Proc. National Acad. Sci. U.S.A. 97 10684/2 This cladistic approach contrasts with the more traditional phenetic approach in which overall similarity (involving an aggregation of characters) is used to infer relationships.

Soc. 135 3 When a good fossil record is available..the whole evolutionary dendrite can be worked out for that group simply by putting those forms together that are most alike phenetically. 1990 P. C. Sereno in K. Carpenter & P. J. Currie Dinosaur Systematics (1992) i. 11 In a diagram of three taxa A, B and C,..A and B..are closer phenetically, because they exhibit far fewer autapomorphies than occur in taxon C. pheˈneticism n. the use of phenetic classification; phenetics.

Jrnl. Philos. Sci. 49 204 Perhaps the worst problem with pheneticism is that there is no reason to believe that the resultant taxa reflect any important biological phenomena. pheˈneticist n. a taxonomist who uses or advocates phenetic classification.
