By the center of the twentieth century the museum-based classical zoologists had been being appeared down on. Their conventional pursuit of describing, naming and cataloguing species that had been believed to be newly found, or of revising classifications and taxonomy of complete teams of animals, was—and certainly in Britain nonetheless is—most positively out of vogue. The classical museum zoologists, with some notable exceptions, had change into wedded to the notion that solely morphological characters might and must be utilized in systematics and taxonomy. What was as soon as a mandatory strategy as the one one out there had change into a dogma.
Deryk Frazer, writing in 1983, offered a beautiful instance in his recollections:
I keep in mind a scientific assembly of the Zoological Society, the place their secretary Lord Chaplin[*] gave a paper on the European and Mediterranean treefrogs (i.e. Hyla arborea†, meridionalis and savigny) the place he lined their distribution and possible areas of origin, look—together with variations in profile of nostril and mouth which might solely be seen in dwelling people, and recordings of the mating calls. His conclusions had been fairly inescapable, that they had been two distinct species, certainly one of which was separated into two subspecies. One realized zoologist then rose to his toes and stated that he was not ready to simply accept this, since you couldn’t distinguish useless people from each other. These days we’ve got the added weapons of sound spectrogram, chromosome image and the outcomes of hybridisation, for a begin.
The perspective of the ‘realized zoologist’ with useless people I see being repeated by these of molecular persuasion, nonetheless incomplete, inappropriate or deceptive their restricted knowledge on mitochondrial or nuclear DNA. Each the traditionalists and their fashionable counterparts remind me of the story of the drunk trying to find his home keys beneath a road mild. ‘Was that the place you misplaced them?’ the passerby requested. ‘No, it’s the one place I can see’ was the reply.

*Anthony Freskyn Charles Hamby Chaplin, third Viscount Chaplin from 1949 (1906-1981) was Secretary of the Zoological Society of London from 1952 till 1955. An newbie zoologist and composer he had a depressing time as Secretary. He was in workplace when George Cansdale was sacked as superintendent of London Zoo. The presentation to the Society have to be that given by Chaplin and Jack Lester on treefrogs and different amphibians which appeared within the account of conferences (Proceedings of the Zoological Society of London 124, 197-197, 1954).
