Download and read online The Evolutionary Synthesis in PDF and EPUB Biology was forged into a single, coherent science only within living memory. In this volume the thinkers responsible for the "modern synthesis" of evolutionary biology and genetics come together to analyze that remarkable event. In a new Preface, Ernst Mayr calls attention to the fact that scientists in different biological disciplines varied considerably in their degree of acceptance of Darwin's theories. Mayr shows us that these differences were played out in four separate periods: 1859 to 1899, 1900 to 1915, 1916 to 1936, and 1937 to 1947. He thus enables us to understand fully why the synthesis was necessary and why Darwin's original theory—that evolutionary change is due to the combination of variation and selection—is as solid at the end of the twentieth century as it was in 1859.

Download and read online The Hierarchical Genome and Differentiation Waves in PDF and EPUB Over the past few decades numerous scientists have called for a unification of the fields of embryo development, genetics, and evolution. Each field has glaring holes in its ability to explain the fundamental phenomena of life. In this book, the author shows how the phenomenon of cell differentiation, considered in its temporal and spatial aspects during embryogenesis, provides a starting point for a unified theory of multicellular organisms (plants, fungi and animals), including their evolution and genetics. This unification is based on the recent discovery of differentiation waves by the author and his colleagues, described in the appendices, and illustrated by a flip movie prepared by a medical artist. To help the reader through the many fields covered, a glossary is included. This book will be of great value to the researcher and practicing doctors/scientists alike. The research students will receive an in-depth tutorial on the topics covered. The seasoned researcher will appreciate the applications and the gold mine of other possibilities for novel research topics.

The superb use of historical ancedotes to illustrate the progression of the author's ideas made the book a pleasure to read. As a framework for future experimentation, this work argues convincingly for the use of physical principles in our treatment of developmental genetics.” Graham Dellaire, PhD MRC Human Genetics Unit, Edinburgh, UK “It is rare in science to see an individual challenge the traditional view. Dr Richard Gordon by doing so, shows how the discovery of an unusual wave on the surface of a salamander embryo has radical implications for the unification of the forces of evolution, genetics and development. This book, his magnum opus, is a major achievement in all these disciplines.” C Cristofre Martin, PhD University of Saskatchewan, Saskatoon, Canada “Richard Gordon, discover of the 'differentiation waves' in embryogenesis, has now written an Opus Magnum on the theoretical frontier. The Hierarchical Genome provides a whole new synthesis of development, genetics, and evolution in that it distils the essentials of the logic of evolution in each of the respective domains. Based on the agency of logical, rather than merely physical, differentiation trees on each level, Gordon provides strong support for the idea of a 'fractal evolution', which must be seen as a novel and promising alternative to the more constraining options of gradualism or punctuated equilibrium ... The book is strongly recommended for anyone interested in a high-level discussion of the basic principles of evolution.” Gerhard Grössing, PhD Director Austrian Institute for Nonlinear Studies, Vienna, Austria “A talented theoretical biologist, Gordon presents a comprehensive, thorough and radically-new look at developmental biology. Even if one does not accept his interpretation of development in terms of cell state splitters and differentiation waves, the book is a fresh, amazing and fascinating summary uniting key fields in biology.” Michael A Goldman, PhD San Francisco State University, San Francisco, USA “... as a magnum opus, or a chance for a scientist to expound ideas at leisure and set out a vision, it's a remarkable achievement.” UK Nonlinear News “The author is certainly a polymath with a sound judgment on widely different areas of knowledge ... Readers who have the luxury of leisurely going through hard facts intertwined with historical and philosophical diversions will find the book delightful.” BioEssays

Download and read online Haeckel s Embryos in PDF and EPUB Pictures from the past powerfully shape current views of the world. In books, television programs, and websites, new images appear alongside others that have survived from decades ago. Among the most famous are drawings of embryos by the Darwinist Ernst Haeckel in which humans and other vertebrates begin identical, then diverge toward their adult forms. But these icons of evolution are notorious, too: soon after their publication in 1868, a colleague alleged fraud, and Haeckel’s many enemies have repeated the charge ever since. His embryos nevertheless became a textbook staple until, in 1997, a biologist accused him again, and creationist advocates of intelligent design forced his figures out. How could the most controversial pictures in the history of science have become some of the most widely seen? In Haeckel’s Embryos, Nick Hopwood tells this extraordinary story in full for the first time. He tracks the drawings and the charges against them from their genesis in the nineteenth century to their continuing involvement in innovation in the present day, and from Germany to Britain and the United States. Emphasizing the changes worked by circulation and copying, interpretation and debate, Hopwood uses the case to explore how pictures succeed and fail, gain acceptance and spark controversy. Along the way, he reveals how embryonic development was made a process that we can see, compare, and discuss, and how copying—usually dismissed as unoriginal—can be creative, contested, and consequential. With a wealth of expertly contextualized illustrations, Haeckel’s Embryos recaptures the shocking novelty of pictures that enthralled schoolchildren and outraged priests, and highlights the remarkable ways these images kept on shaping knowledge as they aged.
