Animal Species And Evolution,New

Reviewa Truly Great Work, Which Will Remain A Landmark In The Biology Of Our Age. (Theodosius Dobzhansky Columbia University)I Have Been Reading Ernst Mayr'S Animal Species And Evolution With 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 Cohen Harvard University)A Major Work Of Scholarship By One Of The Few Grand Masters Of Evolutionary Genetics And Taxonomy. (P. B. Medawar Medical Research Council, London)It Is The Definitive Treatment Of Systematics And Evolution As Interpreted In The Light Of The New Systematics. (Charles D. Michener University Of Kansas)Ernst Mayr Has Described With Lucidity And Verve The Modern Concepts That Elucidate The Golden Thread Of Biologyto Wit, Evolution... [His] Treatise Makes Books On Evolution Published Lust A Few Years Ago Appear Antiquated. (Herman T. Spieth University 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 Simpson Harvard 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 Lerner University Of California)Product Descriptionthis Masterly And Longawaited Work Is A Full Exposition, Synthesis, Summation, And Critical Evaluation Of The Present State Of Man'S Knowledge About The Nature Of Animal Species And Of The Part They Play In The Processes Of Evolution.In A Series Of Twenty Chapters, Mr. Mayr Presents A Consecutive Story, Beginning With A Description Of Evolutionary Biology And Ending With A Discussion Of Man As A Biological Species. Calling Attention To Unsolved Problems, And Relating The Evolutionary Subject Matter To Appropriate Material From Other Fields, Such As Physiology, Genetics, And Biochemistry, The Author Integrates And Interprets Existing Data. Believing That An Unequivocal Stand Is More Likely To Produce Constructive Criticism Than Evasion Of An Issue, He Does Not Hesitate To Choose That Interpretation Of A Controversial Matter Which To Him Seems Most Consistent With The Emerging Picture Of The Evolutionary Process.Between The Terminal Points Mentioned Above, Mr. Mayr Pursues The Narrative Through Discussions Of Species Concepts And Their Application, Morphological Species Characters And Sibling Species, Biological Properties Of Species, Isolating Mechanisms, Hybridization, The Variation And Genetics Of Populations, Storage And Protection Of Genetic Variation, The Unity Of The Genotype, Geographic Variation, The Polytypic Species Of The Taxonomist, The Population Structure Of Species, Kinds Of Species, Multiplication Of Species, Geographic Speciation, The Genetics Of Speciation, The Ecology Of Speciation, And Species And Transpecific Evolution. The Volume Provides A Valuable Glossary; And An Inclusive Bibliography Greatly Extends Its Range For Those Who Wish To Investigate Special Aspects Of The Material. Animal Species And Evolution Is Presented As A Permanent Entity. In Accordance With The Author'S Feeling That The Acquisition Of New Knowledge Will Require A New Statement, Rather Than An Emendation Of A Previous One, No Substantive Revisions Of This Volume Are Planned For Future Printings.Because Of The Impossibility Of Experimenting With Man, And Because An Understanding Of Man'S Biology Is Indispensable For Safeguarding His Future, Emphasis Throughout This Book Is Placed On Those Findings From The Higher Animals Which Are Directly Applicable To Man. In His Final Chapter On Hominids And The Various Forms Of Homo, Mr. Mayr Comes To The Conclusion That, While Modem Man Appears To Be Just As Well Adapted For Survival Purposes As Were His Ancestors, There
