Book excerpt: Conrad Hal Waddington's Organisers and Genes, published in 1940, is a summary of available research and theoretical framework for many concepts related to tissue differentiation in the developing embryo. The book is composed of two main conceptual sections. The first section explores the action and nature of the organizer, while the second section delves into genes and their influence on development. In this book Waddington explored organizers in terms of their capacity and method of induction. First he examined the nature of induction, discussing crucial experiments concerning the organizer, including Hans Spemann's discovery of the organizer, and his own research into organizers in higher birds and mammals. Waddington separated the action of the organizer into two distinct categories, evocation and individuation, discussed below. The main experimental approach discussed in this book involved grafting organizing tissue from one embryo or region of an embryo to another. Waddington described evocation as non-assimilative induction, or a one-way inducing signal. He presented this as a chemical signal and illustrated evocation with the dead organizer experiment. The dead organizer was shown to be capable of inducing differentiation of neural tissue in the ectoderm. He also included chemical induction by estrogens and steroids as other evocative signals. An important aspect of any signal of evocation, as presented by Waddington, is that the signal is specific to the differentiation of a certain tissue type.

Download or read book The Life Organic written by Erik Peterson and published by University of Pittsburgh Press. This book was released on 2016-12-23 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: As scientists debated the nature of life in the nineteenth century, two theories predominated: vitalism, which suggested that living things contained a "vital spark," and mechanism, the idea that animals and humans differed from nonliving things only in their degree of complexity. Erik Peterson tells the forgotten story of the pursuit of a Third Way in biology, known by many names, including "the organic philosophy," which gave rise to C. H. Waddington's work in the subfield of epigenetics: an alternative to standard genetics and evolutionary biology that captured the attention of notable scientists from Francis Crick to Stephen Jay Gould. The Life Organic chronicles the influential biologists, mathematicians, philosophers, and biochemists from both sides of the Atlantic who formed Joseph Needham's Theoretical Biology Club, defined and refined Third-Way thinking through the 1930s, and laid the groundwork for some of the most cutting-edge achievements in biology today. By tracing the persistence of organicism into the twenty-first century, this book also raises significant questions about how we should model the development of the discipline of biology going forward.

Download or read book Plastic Reason written by Tobias Rees and published by Univ of California Press. This book was released on 2016-05-03 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Throughout the twentieth century, neuronal researchers knew the adult human brain to be a thoroughly fixed and immutable cellular structure, devoid of any developmental potential. Plastic Reason is a study of the efforts of a few Parisian neurobiologists to overturn this rigid conception of the central nervous system by showing that basic embryogenetic processesÑmost spectacularly the emergence of new cellular tissue in the form of new neurons, axons, dendrites, and synapsesÑcontinue in the mature brain. Furthermore, these researchers sought to demonstrate that the new tissues are still unspecific and hence literally plastic, and that this cellular plasticity is constitutive of the possibility of the human. Plastic Reason, grounded in years of fieldwork and historical research, is an anthropologistÕs account of what has arguably been one of the most sweeping events in the history of brain researchÑthe highly contested effort to consider the adult brain in embryogenetic terms. A careful analysis of the disproving of an established truth, it reveals the turmoil that such a disruption brings about and the emergence of new possibilities of thinking and knowing.

Download or read book The Eukaryote Genome in Development and Evolution written by John Bernard and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'The mind unlearns with difficulty what has long been impressed upon it. ' Seneca Reductionism, is, without question, the most successful analytical approach available to the experimental scientist. With the advent of techniques for cloning and sequencing DNA, and the development of a variety of molecular probes for localizing macromolecules in cells and tissues, the biologist now has available the most powerful reductionist tools ever invented. The application of these new technologies has led to a veritable explosion of facts regarding the types and organization of nucleotide sequences present in the genomes of eukaryotes. These data offer a level of precision and predictability which is unparalleled in biology. Recombinant DNA techniques were initially developed to gather information about the structure and organization of the DNA sequences within a genome. The power and potential of these techniques, however, extend far beyond simple data collection of this kind. In an attempt to use the new technology as a basis for analyzing development and evolution, attention was first focused on the topic of gene regulation, an approach that had proven so successful in prokaryotes. It is now clear that this has not been an adequate approach. Lewin (1984) has quoted Brenner as stating 'at the beginning it was said that the answer to the understanding of development was going to come from a knowledge of the molecular mechanisms of gene control. I doubt whether anyone believes this any more.
Download or read book Growing Explanations written by M. Norton Wise and published by Duke University Press. This book was released on 2004-11-24 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: For much of the twentieth century scientists sought to explain objects and processes by reducing them to their components—nuclei into protons and neutrons, proteins into amino acids, and so on—but over the past forty years there has been a marked turn toward explaining phenomena by building them up rather than breaking them down. This collection reflects on the history and significance of this turn toward “growing explanations” from the bottom up. The essays show how this strategy—based on a widespread appreciation for complexity even in apparently simple processes and on the capacity of computers to simulate such complexity—has played out in a broad array of sciences. They describe how scientists are reordering knowledge to emphasize growth, change, and contingency and, in so doing, are revealing even phenomena long considered elementary—like particles and genes—as emergent properties of dynamic processes. Written by leading historians and philosophers of science, these essays examine the range of subjects, people, and goals involved in changing the character of scientific analysis over the last several decades. They highlight the alternatives that fields as diverse as string theory, fuzzy logic, artificial life, and immunology bring to the forms of explanation that have traditionally defined scientific modernity. A number of the essays deal with the mathematical and physical sciences, addressing concerns with hybridity and the materials of the everyday world. Other essays focus on the life sciences, where questions such as “What is life?” and “What is an organism?” are undergoing radical re-evaluation. Together these essays mark the contours of an ongoing revolution in scientific explanation. Contributors.
