A discussion between
Ernst Mayr
Professor of Zoology
In the University of Harvard and A. J. Cain
Animal Taxonomist
In the University of Oxford
In The Origin of Species, published a hundred years ago this year, the principal problem that Darwin did not solve was, in fact, the origin of species-he was more concerned to establish natural selection as a means of evolutionary change within a population.
Professor Mayr claims that the real origin of species is a comparatively recent discovery made primarily by students of avian systematics, and he discusses this thesis with Dr. Cain.
