Animal Species and Evolution
A truly great work, which will remain a landmark in the biology of our age. (Theodosius DobzhanskyColumbia University)I have been reading Ernst Mayr'sAnimal Species and Evolutionwith avidity... Notably, the introductory classification and analysis of evolutionary theories clarifies the concepts of Darwin, his predecessors and his successors, with a profundity that will clearly shape future writing on the history of evolution. (I. Bernard CohenHarvard University)A major work of scholarship by one of the few Grand Masters of evolutionary genetics and taxonomy. (P. B. MedawarMedical Research Council, London)It is the definitive treatment of systematics and evolution as interpreted in the light of the New Systematics. (Charles D. MichenerUniversity of Kansas)Ernst Mayr has described with lucidity and verve the modern concepts that elucidate the Golden Thread of Biology--to wit, Evolution... [His] treatise makes books on Evolution published lust a few years ago appear antiquated. (Herman T. SpiethUniversity of California)This is the soundest, most complete, and best documented study ever published on genetical characteristics and evolutionary processes in animal populations around the crucial level of the species. (George Gaylord SimpsonHarvard University)A work of extraordinary comprehensiveness. . . I have no doubt that it is destined to be an abiding landmark in the study of evolution. (I. Michael LernerUniversity of California)
