Clashing views on easy methods to recognise species within the Nineteen 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 entire teams of animals, was—and certainly in Britain nonetheless is—most undoubtedly out of trend. The classical museum zoologists, with some notable exceptions, had turn out to be wedded to the notion that solely morphological characters may and must be utilized in systematics and taxonomy. What was as soon as a essential method as the one one obtainable had turn out to be a dogma.

    Deryk Frazer, writing in 1983, supplied a beautiful instance in his recollections:

    I bear 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 may solely be seen in residing people, and recordings of the mating calls. His conclusions had been fairly inescapable, that they had been two distinct species, one in all which was separated into two subspecies. One realized zoologist then rose to his toes and mentioned that he was not ready to just accept this, since you couldn’t distinguish useless 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 ‘realized zoologist’ with useless 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 trendy counterparts remind me of the story of the drunk looking for his home keys below 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.

    This treefrog (Hyla arborea) we noticed in Hungary in 2010

    *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).
