Available in PDF, EPUB and Kindle. Book excerpt: Darwin’s Pangenesis and Its Rediscovery Part A highlights the findings of Darwin's Pangenesis, an expanded cell theory and unified theory of heredity and variation that strengthened his theory of evolution and explained many phenomena of life. Now, new advances and the discovery of circulating cell-free DNA, mobile RNAs, prions and extracellular vesicles are providing new breakthroughs, thus increasing evidence on the inheritance of acquired characters, graft hybridization, and many other phenomena that Pangenesis suggests. Sections of note in this volume include the rationale, criticisms, influence and recent molecular evidence of Darwin's Pangenesis, as well as its relation to the inheritance of acquired characters, which is often included under the blanket term "transgenerational epigenetic inheritance." Presents a comprehensive approach to Darwin’s Pangenesis, which is so little understood that few have recognized its far-reaching importance, but seems today surprisingly modern Links Darwin's hypothetical gemmules with circulating cell-free DNA, mobile RNAs, prions and extracellular vesicles, shedding new light on an old theory Includes section on Darwin's Pangenesis in relation to the Lamarckian inheritance of acquired characters, a central debate in the history of genetics

Available in PDF, EPUB and Kindle. Book excerpt: Darwin’s Pangenesis and its Rediscovery Part B explores Darwin's Pangenesis, an expanded cell theory and unified theory of heredity and variation from over 150 years ago that strengthened his theory of evolution and explained many phenomena of life. Now, new discoveries on circulating DNA, mobile RNAs, prions and extracellular vesicles are providing striking evidence for the chemical existence of Darwin’s imaginary gemmules. In addition, new evidence for the inheritance of acquired characters, graft hybridization, and many other phenomena that Pangenesis supposedly explains are progressing, and are hence explored in this comprehensive volume. Specific chapters in this new volume include Darwin and Mendel: The Historical Connection, Darwin’s Pangenesis and Graft Hybridization, Darwin’s Pangenesis and Medical Genetics, Darwin’s Pangenesis and Certain Anomalous Phenomena, and Natural Selection and Pangenesis: The Darwinian Synthesis. Presents the only book on Darwin’s Pangenesis, an expanded cell theory and a unified theory of heredity, variation, development and reproduction Highlights Darwin’s tremendous contributions to genetics, as well as Mendel’s legacy and limitations Includes sections on Darwin's Pangenesis in relation to graft hybridization, medical genetics, evolutionary theory, along with many other updates

Download or read book History of Genetics written by Hans Stubbe and published by MIT Press (MA). This book was released on 1972 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: This history traces the evolution of man's ideas concerning the generational continuities and changes of living organisms from the earliest times to the rediscovery of Mendel's fundamental laws, first brought to light in 1865 but neglected until the early 1900s. The dramatic story of the independent studies by Bateson (who coined the word "genetic"), De Vries, Correns, and Tschermak which finally led to public recognition of these laws is given in full detail.Reviewing the first German edition of the book in "Isis, " Zirkle wrote that "The overall history of genetics falls easily and naturally into three periods. Recently, the first...has been covered excellently by Hans Stubbe."Likewise, reviewing the second German edition (1965) for "Science, " the geneticist L. C. Dunn noted that "It is a sign of the widening interest in the origin of genetics that the first brief comprehensive account of its history before 1900 has already reached a second edition...."The first edition was an excellent and succinct account of the work of Mendel and of his predecessors beginning with the first domesticators of plants and animals. The first chapters were devoted to ideas about reproduction and heredity as found in the works of the Greek and Roman writers of antiquity and of scientists and observers of the Middle Ages. The beginning of a new era in the 18th century was noted in the controversy concerning performation and epigenesis and especially in the botanical discoveries of the late 17th century and the 18th century (by Camerarius, Linnaeus, and Kolreuter). Some 40 pages (now expanded to 60) were devoted to the plant breeders and theorists of evolution in the 19th century, including Mendel, and were followed by an excellent chapter on the origin of variations and the mutation theory.... The last chapters, about a fifth of the text, were devoted to the great cytological discoveries of the 19th century, to Weismann and the germ plasm theory, to the rediscoveries of Mendel's laws, and to the first conceptions of a chromosome theory of heredity."The second edition is an improvement and expansion of the first. Forty pages have been added to the text, including a 12-page facsimile of Mendel's letter of 3 July 1870 to Carl von Naegeli (the holograph has not been published previously) and 115 titles added to the already extensive bibliography. Proper attention has now been paid to Karl Pearson's contributions (1900 to 1909), to the theory of Mendelian equilibrium, and to Fisher's critique of Mendel's theory...."A valuable feature of the book is the brief biographical notices of most of the chief actors in the history of genetics up to and including the rediscoverers of 1900. Most of these notices are accompanied by portraits."The present English translation is based on the second German edition, but it contains in turn a wealth of new material added by the author since the German publication.

Download or read book Scientific Discovery Case Studies written by Thomas Nickles and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: The history of science is articulated by moments of discovery. Yet, these 'moments' are not simple or isolated events in science. Just as a scientific discovery illuminates our understanding of nature or of society, and reveals new connections among phenomena, so too does the history of scientific activity and the analysis of scientific reasoning illuminate the processes which give rise to moments of discovery and the complex network of consequences which follow upon such moments. Understanding discovery has not been, until recently, a major concern of modem philosophy of science. Whether the act of discoyery was regarded as mysterious and inexplicable, or obvious and in no need of explanation, modem philosophy of science in effect bracketed the question. It concentrated instead on the logic of scientific explanation or on the issues of validation or justification of scientific theories or laws. The recent revival of interest in the context of discovery, indeed in the acts of discovery, on the part of philosophers and historians of science, represents no one particular method'ological or philosophical orientation. It proceeds as much from an empiricist and analytical approach as from a sociological or historical one; from considerations of the logic of science as much as from the alogical or extralogical contexts of scientific tho'¢tt and practice. But, in general, this new interest focuses sharply on the actual historical and contem porary cases of scientific discovery, and on an examination of the act or moment of discovery in situ.

Download or read book In Pursuit of the Gene written by James Schwartz and published by Harvard University Press. This book was released on 2010-03-30 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mystery of inheritance has captivated thinkers since antiquity, and the unlocking of this mystery—the development of classical genetics—is one of humanity’s greatest achievements. This great scientific and human drama is the story told fully and for the first time in this book. Acclaimed science writer James Schwartz presents the history of genetics through the eyes of a dozen or so central players, beginning with Charles Darwin and ending with Nobel laureate Hermann J. Muller. In tracing the emerging idea of the gene, Schwartz deconstructs many often-told stories that were meant to reflect glory on the participants and finds that the “official” version of discovery often hides a far more complex and illuminating narrative. The discovery of the structure of DNA and the more recent advances in genome science represent the culmination of one hundred years of concentrated inquiry into the nature of the gene. Schwartz’s multifaceted training as a mathematician, geneticist, and writer enables him to provide a remarkably lucid account of the development of the central ideas about heredity, and at the same time bring to life the brilliant and often eccentric individuals who shaped these ideas. In the spirit of the late Stephen Jay Gould, this book offers a thoroughly engaging story about one of the oldest and most controversial fields of scientific inquiry. It offers readers the background they need to understand the latest findings in genetics and those still to come in the search for the genetic basis of complex diseases and traits.

Download or read book The Evolution of Darwinism written by Timothy Shanahan and published by Cambridge University Press. This book was released on 2004-03-15 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: No other scientific theory has had as tremendous an impact on our understanding of the world as Darwin's theory as outlined in his Origin of Species, yet from the very beginning the theory has been subject to controversy. The Evolution of Darwinism, first published in 2004, focuses on three issues of debate - the nature of selection, the nature and scope of adaptation, and the question of evolutionary progress. It traces the varying interpretations to which these issues were subjected from the beginning and the fierce contemporary debates that still rage on and explores their implications for the greatest questions of all: Where we come from, who we are and where we might be heading. Written in a clear and non-technical style, this book will be of use as a textbook for students in the philosophy of science who need to become familiar with the background to the debates about evolution.

Download or read book Fundamentals of Genetics written by Leslie Vega & and published by Scientific e-Resources. This book was released on 2019-09-13 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetics is the study of genes-what they are, what they do, and how they work. Genes inside the nucleus of a cell are strung together in such a way that the sequence carries information: that information determines how living organisms inherit various features. For example, offspring produced by sexual reproduction usually look similar to each of their parents because they have inherited some of each of their parents' genes. Genetics identifies which features are inherited, and explains how these features pass from generation to generation. The fundamentals of genetics has been designed with the objective of providing a sound understanding of the fundamentals and basic principles of genetics. An attempt has been made to present the subject matter as simple, concise, and explicit. Elements of genetics is intended to meet the needs of the shorter more applied course in introductory genetics. The aim of this text is to focus on the basics of genetics and presents those fundamentals as clearly and concisely as possible. In addition to inheritance, genetics studies how genes are turned on and off to control what substances are made in a cell-gene expression; and how a cell divides-mitosis or meiosis. Another example is a person's height: it is determined by both genetics and nutrition. This unique presentation on basic of applied genetics is of immense use to teachers, students, researches and general readers.

Download or read book Handbook of Developmental Systems Theory and Methodology written by Peter C. M. Molenaar and published by Guilford Publications. This book was released on 2013-12-09 with total page 529 pages. Available in PDF, EPUB and Kindle. Book excerpt: Developmental systems theory provides powerful tools for predicting complex, dynamic interactions among biological and environmental processes in human behavior and health. This groundbreaking handbook provides a roadmap for integrating key concepts of developmental systems theory (such as self-organization, reciprocal dynamic interaction, and probabilistic epigenesis) and simulation models (connectionist and agent-based models) with advanced dynamic modeling approaches for testing these theories and models. Internationally renowned developmental science scholars present innovations in research design, measurement, and analysis that offer new means of generating evidence-based decisions to optimize the course of health and positive functioning across the life span. Topics include epigenetic development and evolution; the relationship between neural systems growth and psychological development; the role of family environments in shaping children's cognitive skills and associated adult outcomes, and more.

Download or read book The Century of the Gene written by Evelyn Fox KELLER and published by Harvard University Press. This book was released on 2009-06-30 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a book that promises to change the way we think and talk about genes and genetic determinism, Evelyn Fox Keller, one of our most gifted historians and philosophers of science, provides a powerful, profound analysis of the achievements of genetics and molecular biology in the twentieth century, the century of the gene. Not just a chronicle of biology’s progress from gene to genome in one hundred years, The Century of the Gene also calls our attention to the surprising ways these advances challenge the familiar picture of the gene most of us still entertain. Keller shows us that the very successes that have stirred our imagination have also radically undermined the primacy of the gene—word and object—as the core explanatory concept of heredity and development. She argues that we need a new vocabulary that includes concepts such as robustness, fidelity, and evolvability. But more than a new vocabulary, a new awareness is absolutely crucial: that understanding the components of a system (be they individual genes, proteins, or even molecules) may tell us little about the interactions among these components. With the Human Genome Project nearing its first and most publicized goal, biologists are coming to realize that they have reached not the end of biology but the beginning of a new era. Indeed, Keller predicts that in the new century we will witness another Cambrian era, this time in new forms of biological thought rather than in new forms of biological life.

Download or read book Making Sense of Genes written by Kostas Kampourakis and published by Cambridge University Press. This book was released on 2017-03-30 with total page 319 pages. Available in PDF, EPUB and Kindle. Book excerpt: What are genes? What do genes do? These seemingly simple questions are in fact challenging to answer accurately. As a result, there are widespread misunderstandings and over-simplistic answers, which lead to common conceptions widely portrayed in the media, such as the existence of a gene 'for' a particular characteristic or disease. In reality, the DNA we inherit interacts continuously with the environment and functions differently as we age. What our parents hand down to us is just the beginning of our life story. This comprehensive book analyses and explains the gene concept, combining philosophical, historical, psychological and educational perspectives with current research in genetics and genomics. It summarises what we currently know and do not know about genes and the potential impact of genetics on all our lives. Making Sense of Genes is an accessible but rigorous introduction to contemporary genetics concepts for non-experts, undergraduate students, teachers and healthcare professionals.

Download or read book Reasoning in Biological Discoveries written by Lindley Darden and published by Cambridge University Press. This book was released on 2006-06-26 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reasoning in Biological Discoveries brings together a series of essays, which focus on one of the most heavily debated topics of scientific discovery. Collected together and richly illustrated, Darden's essays represent a groundbreaking foray into one of the major problems facing scientists and philosophers of science. Divided into three sections, the essays focus on broad themes, notably historical and philosophical issues at play in discussions of biological mechanism; and the problem of developing and refining reasoning strategies, including interfield relations and anomaly resolution. Darden summarizes the philosophy of discovery and elaborates on the role that mechanisms play in biological discovery. Throughout the book, she uses historical case studies to extract advisory reasoning strategies for discovery. Examples in genetics, molecular biology, biochemistry, immunology, neuroscience and evolutionary biology reveal the process of discovery in action.
