Download or read book Evolutionary Biology written by Max Hecht and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evolutionary Biology, of which this is the nineteenth volume, continues to offer its readers a wide range of original articles, reviews, and com mentaries on evolution, in the broadest sense of that term. The topics of the reviews range from anthropology and behavior to molecular biology and systematics. In recent volumes, a broad spectrum of articles have appeared on such subjects as natural selection among replicating molecules in vitro, mate recognition and the reproductive behavior in Drosophila, evolution of the monocotyledons, species selection, and the communication net work made possible among even distantly related genera of bacteria by plasmids and other transposable elements. Articles such as these, often too long for standard journals, are the stuff of Evolutionary Biology. The editors continue to solicit manuscripts on an international scale in an effort to see that everyone of the many facets of biological evolution is covered. Manuscripts should be sent to anyone of the following: Max K. Hecht, Department of Biology, Queens College of the City University of New York, Flushing, New York 11367; Bruce Wallace, Department of Biology, Virginia Polytechnic Institute and State University, Blacks burg, Virginia 24061; Ghillian T.

Download or read book Homology written by Gregory R. Bock and published by John Wiley & Sons. This book was released on 2008-04-30 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'Homology' as a concept became increasingly elusive during the course of the 20th century. The central debates and controversies concern both fundamental definitions and the nature of the criteria by which homology is judged. Attempts to move away from comparative morphology to ideas based on developmental pathways have tended to founder on the fact that developmental pathways evolve and that similar cells or tissues or structures in animals will often have different developmental origins. The use of information about conserved molecules in seemingly conserved developmental processes has also proven controversial. In molecular biology, the use of the term 'homology' has given rise to more debate, although here the issue seems to involve primarily the criteria for assessing whether parts of genes are the same because of shared descent or for other reasons. The contributions to the book explore these topics systematically. There are chapters on the historical development of the concept of homology and its use in population studies. Other chapters deal with issues of homology in morphological and developmental studies, in behavioural studies, and especially in studies at the level of molecular genetics.

Download or read book Evolutionary Innovations written by Matthew H. Nitecki and published by University of Chicago Press. This book was released on 1990-07-14 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evolutionary innovations—the bony skeleton of vertebrates, avian flight, or the insect pollination system of angiosperms, for example—have in recent years become the focus of much fertile new research in evolutionary biology. Innovations may hold the keys to understanding why whole new groups of organisms evolve or, conversely, why groups of organisms become extinct. This volume brings together contributors from the fields of morphology, genetics, embryology, physiology, and paleontology to present research on evolutionary innovations and to suggest directions for further work. The topics covered include the plurality of evolutionary innovations, patterns and processes at different hierarchical levels, evolutionary genetics of adaptations, heterochrony and other mechanisms of radical evolutionary change in early development, developmental mechanisms at the origin of morphological novelty, the evolution of morphological variation patterns, functional design and its punctuated products, plausibility and testability in assessing the consequences of evolutionary innovations, paradigms and pitfalls of studying physiological evolution, polyphyletic constructional breakthroughs in fossil and extant species, ecology of evolutionary innovations in the fossil record.

Download or read book The Shape of Life written by Rudolf A. Raff and published by University of Chicago Press. This book was released on 2012-12-14 with total page 545 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rudolf Raff is recognized as a pioneer in evolutionary developmental biology. In their 1983 book, Embryos, Genes, and Evolution, Raff and co-author Thomas Kaufman proposed a synthesis of developmental and evolutionary biology. In The Shape of Life, Raff analyzes the rise of this new experimental discipline and lays out new research questions, hypotheses, and approaches to guide its development. Raff uses the evolution of animal body plans to exemplify the interplay between developmental mechanisms and evolutionary patterns. Animal body plans emerged half a billion years ago. Evolution within these body plans during this span of time has resulted in the tremendous diversity of living animal forms. Raff argues for an integrated approach to the study of the intertwined roles of development and evolution involving phylogenetic, comparative, and functional biology. This new synthesis will interest not only scientists working in these areas, but also paleontologists, zoologists, morphologists, molecular biologists, and geneticists.

Download or read book Origination of Organismal Form written by Gerd B. Muller and published by MIT Press. This book was released on 2003-01-03 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: A more comprehensive version of evolutionary theory that focuses as much on the origin of biological form as on its diversification. The field of evolutionary biology arose from the desire to understand the origin and diversity of biological forms. In recent years, however, evolutionary genetics, with its focus on the modification and inheritance of presumed genetic programs, has all but overwhelmed other aspects of evolutionary biology. This has led to the neglect of the study of the generative origins of biological form. Drawing on work from developmental biology, paleontology, developmental and population genetics, cancer research, physics, and theoretical biology, this book explores the multiple factors responsible for the origination of biological form. It examines the essential problems of morphological evolution—why, for example, the basic body plans of nearly all metazoans arose within a relatively short time span, why similar morphological design motifs appear in phylogenetically independent lineages, and how new structural elements are added to the body plan of a given phylogenetic lineage. It also examines discordances between genetic and phenotypic change, the physical determinants of morphogenesis, and the role of epigenetic processes in evolution. The book discusses these and other topics within the framework of evolutionary developmental biology, a new research agenda that concerns the interaction of development and evolution in the generation of biological form. By placing epigenetic processes, rather than gene sequence and gene expression changes, at the center of morphological origination, this book points the way to a more comprehensive theory of evolution.

Download or read book Natural Kinds and Classification in Scientific Practice written by Catherine Kendig and published by Routledge. This book was released on 2015-12-22 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: This edited volume of 13 new essays aims to turn past discussions of natural kinds on their head. Instead of presenting a metaphysical view of kinds based largely on an unempirical vantage point, it pursues questions of kindedness which take the use of kinds and activities of kinding in practice as significant in the articulation of them as kinds. The book brings philosophical study of current and historical episodes and case studies from various scientific disciplines to bear on natural kinds as traditionally conceived of within metaphysics. Focusing on these practices reveals the different knowledge-producing activities of kinding and processes involved in natural kind use, generation, and discovery. Specialists in their field, the esteemed group of contributors use diverse empirically responsive approaches to explore the nature of kindhood. This groundbreaking volume presents detailed case studies that exemplify kinding in use. Newly written for this volume, each chapter engages with the activities of kinding across a variety of disciplines. Chapter topics include the nature of kinds, kindhood, kinding, and kind-making in linguistics, chemical classification, neuroscience, gene and protein classification, colour theory in applied mathematics, homology in comparative biology, sex and gender identity theory, memory research, race, extended cognition, symbolic algebra, cartography, and geographic information science. The volume seeks to open up an as-yet unexplored area within the emerging field of philosophy of science in practice, and constitutes a valuable addition to the disciplines of philosophy and history of science, technology, engineering, and mathematics.
