Clashing views on how one can recognise species within the Fifties. The case of the Treefrogs


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 undoubtedly out of trend. 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 vital strategy as the one one obtainable 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, one among which was separated into two subspecies. One discovered zoologist then rose to his toes and stated that he was not ready to simply accept this, since you couldn’t distinguish lifeless people from each other. These days we’ve the added weapons of sound spectrogram, chromosome image and the outcomes of hybridisation, for a begin.

The angle of the ‘discovered zoologist’ with lifeless people I see being repeated by these of molecular persuasion, nevertheless incomplete, inappropriate or deceptive their restricted information 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 underneath 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 beginner 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).
