DOWNLOAD EBOOKIn his extraordinary book, Mayr fully explored, synthesized, and evaluated man's knowledge about the nature of animal species and the part they play in the process of evolution. Now, in this long-awaited abridged edition, Mayr's definitive work is made available to the interested nonspecialist, the college student, and the general reader.

DOWNLOAD EBOOKThis masterly and long-awaited 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 is much evidence to suggest that he is threatened by the loss of his most typically human characteristics. It would be within his power to reverse this tendency.

DOWNLOAD EBOOKAt last both ecology and evolution are covered in this study on the dynamics of size-structured populations. How does natural selection shape growth patterns and life cycles of individuals, and hence the size-structure of populations? This book will stimulate biologists to look into some important and interesting biological problems from a new angle of approach, concerning: - life history evolution, - intraspecific competition and niche theory, - structure and dynamics of ecological communities.

DOWNLOAD EBOOKFascinated by the diversity of living organisms, humans have always been curious about its origin. Darwin was the first to provide the scholary and persuasive thesis for gradual evolution and speciation under natural selection. Although we now have much information on evolution, we still don't understand it in detail. Many questions still remain open due to the complexity and multiplicity of interacting factors. Several approaches mainly arising from population ecology and genetics are presented in this book in order to help understand genetic variation and evolution.

DOWNLOAD EBOOKSpeciation is one of the great themes of evolutionary biology. It is the process through which new species are born and diversity generated. Yet for many years our understanding of the process consisted of little more than a perception that if populations are isolated geographically, they will diverge genetically and may come to form new species. This situation began to change in the 1960s as an increasing number of biologists challenged the exclusivity of allopatric speciation and began to probe more deeply into the actual process by which divergence occurs and reproductive isolation is acquired. This focus on process led to many new insights, but numerous questions remain and speciation is now one of the most dynamic areas of research in modern evolutionary biology. This volume presents the newest research findings on speciation bringing readers up to day on species concepts, modes of speciation, and the nature of reproductive barriers. It also discusses the forces that drive divergence of populations, the genetic control of reproductive isolation, and the role played by hybrid zones and hybridization in speciation.
