Understanding how a multicellular animal develops from a single cell (the fertilized egg) poses one of the greatest challenges in biology today. Development from egg to adult involves the sequential expression of virtually the whole of an organism's genetic instructions both in the mother as she lays down developmental cues in the egg, and in the embryo itself. Most of our present information on the role of genes in development comes from the invertebrate fruit fly, Drosophila. The two authors of this text (amongst the foremost authorities in the world) follow the developmental process from fertilization through the primitive structural development of the body plan of the fly after cleavage into the differentiation of the variety of tissues, organs and body parts that together define the fly. The developmental processes are fully explained throughout the text in the modern language of molecular biology and genetics. This text represents the vital synthesis of the subject that many have been waiting for and it will enable many specific courses in developmental biology and molecular genetics to focus on it. It will appeali to 2nd and 3rd year students in these disciplines as well as in biochemistry, neurobiology and zoology. It will also have widespread appeal among researchers. Authored by one of the foremost authorities in the world. A unique synthesis of the developmental cycle of Drosophila - our major source of information on the role of genes in development. Designed to provide the basis of new courses in developmental biology and molecular genetics at senior undergraduate level. A lucid explanation in the modern language of the science.

Insect Molecular Genetics, Third Edition, summarizes and synthesizes two rather disparate disciplines—entomology and molecular genetics. This volume provides an introduction to the techniques and literature of molecular genetics; defines terminology; and reviews concepts, principles, and applications of these powerful tools. The world of insect molecular genetics, once dominated by Drosophila, has become much more diverse, especially with the sequencing of multiple arthropod genomes (from spider mites to mosquitoes). This introduction includes discussion of honey bees, mosquitoes, flour beetles, silk moths, fruit flies, aphids, house flies, kissing bugs, cicadas, butterflies, tsetse flies and armyworms. This book serves as both a foundational text and a review of a rapidly growing literature. With fully revised and updated chapters, the third edition will be a valuable addition to the personal libraries of entomologists, geneticists, and molecular biologists. Up-to-date references to important review articles, websites, and seminal citations in the disciplines Well crafted and instructive illustrations integral to explaining the techniques of molecular genetics Glossary of terms to help beginners learn the vocabulary of molecular biology

Philosophy of Experimental Biology

Philosophy of Experimental Biology explores some central philosophical issues concerning scientific research in experimental biology, including genetics, biochemistry, molecular biology, developmental biology, neurobiology, and microbiology. It seeks to make sense of the explanatory strategies, concepts, ways of reasoning, approaches to discovery and problem solving, tools, models and experimental systems deployed by scientific life science researchers and also integrates developments in historical scholarship, in particular the New Experimentalism. It concludes that historical explanations of scientific change that are based on local laboratory practice need to be supplemented with an account of the epistemic norms and standards that are operative in science. This book should be of interest to philosophers and historians of science as well as to scientists.

Towards a Theory of Development

Is it possible to explain and predict the development of living things? What is development? Articulate answers to these seemingly innocuous questions are far from straightforward. To date, no systematic, targeted effort has been made to construct a unifying theory of development. This novel work offers a unique exploration of the foundations of ontogeny by asking how the development of living things should be understood. It explores the key concepts of developmental biology, asks whether general principles of development can be discovered, and examines the role of models and theories. The two editors (one a biologist with long interest in the theoretical aspects of his discipline, the other a philosopher of science who has mainly worked on biological systems) have assembled a team of leading contributors who are representative of the scientific and philosophical community within which a diversity of thoughts are growing, and out of which a theory of development may eventually emerge. They analyse a wealth of approaches to concepts, models and theories of development, such as gene regulatory networks, accounts based on systems biology and on physics of soft matter, the different articulations of evolution and development, symbiont-induced development, as well as the widely discussed concepts of positional information and morphogenetic field, the idea of a 'programme' of development and its critiques, and the long-standing opposition between preformationist and epigenetic conceptions of development. Towards a Theory of Development is primarily aimed at students and researchers in the fields of 'evo-devo', developmental biology, theoretical biology, systems biology, biophysics, and the philosophy of science.

Bilder schauen wir an, unser Anschauen scheint durch diese Bilder geführt. In der immer stärker anwachsenden Flut solcher Bilder scheint unser Denken mehr und mehr durch dieses Anschauen bestimmt. Dabei offeriert diese Flut meist nur ein Spiel mit bekannten Formen, die variiert und in vielleicht verblüffender Weise präsentiert werden. Oft sind es dabei aber nur Illustrationen, die einen bekannten Gedanken untersetzen. Wo die Bilder aber in Neuland führen, wo sie uns etwas entdecken lassen, ist die Situation anders. Das Bild – und dies interessiert im vorliegenden Band – hat aber seine eigene Logik. Diese Logik ist nicht einfach die, die wir mit dem Bild illustrieren. Es formt sich nach den uns eigenen Anschauungen und leitet uns dann auch in unserem Denken über die Dinge. In ihm meinen wir denn auch Neues entdecken zu können, auf etwas verwiesen zu sein, was wir uns eben nicht schon immer gedacht haben. Wie kommen wir aber eigentlich an solch Neues, wie können wir etwas erkennen, von dem wir noch keinen Begriff haben? Werden wir im Denken solcher Neuigkeiten durch die Anschauung geführt? Greifen wir hier vor das aus, was wir schon begriffen haben? Wenn dies so ist, müssen wir Anschauungen zu denken lernen. Anschauungen zu denken, heißt dann aber nicht einfach zu illustrieren, was wir begriffen haben. Anschauung zu denken, heißt, vor den Begriff zu schauen. Das vorliegende Buch sucht hier nach ersten Antworten.

Morphomechanics of Development

Author: Lev V. Beloussov

This book outlines a unified theory of embryonic development, assuming morphogenesis to be a multi-level process including self-organizing steps while also obeying general laws. It is shown how molecular mechanisms generate mechanical forces, which in the long run lead to morphological changes. Questions such as how stress-mediated feedback acts at the cellular and supra-cellular levels and how executive and regulatory mechanisms are mutually dependent are addressed, while aspects of collective cell behavior and the morphogenesis of plants are also discussed. The morphomechanical approach employed in the book is based on the general principles of self-organization theory.

The common fruit fly - Drosophila melanogaster - has been the subject of genetics research since the early twentieth century. The complete genomic sequence of Drosophila was published in 2000 and it is still the model organism par excellence for the experimental study of biological phenomena and processes. It is also by far the best model for studying gene function in mammals, including humans. Presenting state-of-the-art studies on the behaviour of Drosophila, this volume discusses normal and pathological models of neurobehavioral disorders and encompasses the specialised methods that have been used, from anatomical, histological, immunohistological and neurophysiological to genomic, genetic and behavioural assays. A comprehensive and thorough reference, this volume is a valuable resource for students and researchers alike across several disciplines of life sciences, including behavioral genetics, neurogenetics, behavioral neuroscience, molecular biology, evolutionary biology and population biology.

How is a fertilized egg able to turn itself into an adult? Through a highly original synthesis of science and art, this book vividly describes the recent revolution in our understanding of how plants and animals develop, and the fresh insights this gives us into the nature of evolution and human creativity. - ;How is a tiny fertilised egg able to turn itself into a human being? How can an acorn transform itself into an oak tree? Through a highly original synthesis of science and art, this book vividly describes the recent revolution in our understanding of how plants and animals develop. Drawing on a wide range of material -- from flowers growing petals instead of sex organs, and flies that develop an extra pair of wings, to works by Leonardo and Magritte -- it explains the language and meaning of genes, in an entertaining way that is both accurate and accessible to the general reader. It shows how an organism develops through an interactive dialogue in which there is no clear separation between plan and execution, much as an artist might paint a picture. By explaining how this process has arisen, the book arrives at fresh and exciting insights into the nature of evolution, development and human creativity. -

Gene Expression at the Beginning of Animal Development

The beginning of life may be a miracle to some, and a mystery to others, but it is certainly one of the most exciting and perhaps controversial fields of scientific investigation in the 21st century. Among the metazoa, life begins when an egg is fertilized by a sperm. The sperm provides a genetic blueprint from the father and perhaps some critical proteins. The egg provides a genetic blueprint from the mother together with a large reservoir of mRNAs and proteins that are required for DNA replication, cell division and the onset of zygotic gene expression. All of the thousands of genes in these two mature gametes are transcriptionally silent and remain so until fertilization. This work focuses on three biological systems, providing the reader with a clear understanding of the current state of affairs, and the ability to identify common principles as well as critical differences that are responsible for beginning the process of animal development. The essays presented will be of practical value to all those who are interested in improving fertilization in vitro, in designing novel methods of contraception, in developing preimplantation genetic diagnosis for various diseases, in cloning animals by transplanting nuclei from adult cells to an enucleated egg, and in the application of embryonic stem cells to curing genetic diseases or replacing damaged tissues. But above all, this volume is offered to those who simply have an insatiable curiosity about life and its beginnings.
