Download or read book Darwin’s Pangenesis and Its Rediscovery written by and published by Academic Press. This book was released on 2018-08-03 with total page 156 pages. 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

Download or read book Darwin’s Pangenesis and Its Rediscovery Part B written by Dhavendra Kumar and published by Academic Press. This book was released on 2018-08-16 with total page 154 pages. 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

Book Synopsis In Pursuit of the Gene by : James Schwartz
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.
Book Synopsis Scientific Discovery: Case Studies by : Thomas Nickles
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.

Book Synopsis History of Genetics by : Hans Stubbe
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.

Book Synopsis Reasoning in Biological Discoveries by : Lindley Darden
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 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.
Book Synopsis Fundamentals of Genetics by : Leslie Vega &
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.
Book Synopsis Ending the Mendel-Fisher Controversy by : Allan Franklin
Download or read book Ending the Mendel-Fisher Controversy written by Allan Franklin and published by University of Pittsburgh Pre. This book was released on 2008-03-15 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1865, Gregor Mendel presented "Experiments in Plant-Hybridization," the results of his eight-year study of the principles of inheritance through experimentation with pea plants. Overlooked in its day, Mendel's work would later become the foundation of modern genetics. Did his pioneering research follow the rigors of real scientific inquiry, or was Mendel's data too good to be true-the product of doctored statistics? In Ending the Mendel-Fisher Controversy, leading experts present their conclusions on the legendary controversy surrounding the challenge to Mendel's findings by British statistician and biologist R. A. Fisher. In his 1936 paper "Has Mendel's Work Been Rediscovered?" Fisher suggested that Mendel's data could have been falsified in order to support his expectations. Fisher attributed the falsification to an unknown assistant of Mendel's. At the time, Fisher's criticism did not receive wide attention. Yet beginning in 1964, about the time of the centenary of Mendel's paper, scholars began to publicly discuss whether Fisher had successfully proven that Mendel's data was falsified. Since that time, numerous articles, letters, and comments have been published on the controversy. This self-contained volume includes everything the reader will need to know about the subject: an overview of the controversy; the original papers of Mendel and Fisher; four of the most important papers on the debate; and new updates, by the authors, of the latter four papers. Taken together, the authors contend, these voices argue for an end to the controversy-making this book the definitive last word on the subject.
Book Synopsis Making Sense of Genes by : Kostas Kampourakis
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.

Book Synopsis Darwin, Then and Now by : Richard William Nelson
Download or read book Darwin, Then and Now written by Richard William Nelson and published by iUniverse. This book was released on 2009-07-23 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: Darwin, Then and Now is a journey through the most amazing story in the history of science; encapsulating who Darwin was, what he said and what scientists have discovered since the publication of The Origin of Species in 1859. While recognized as one of the most influential individuals of the twentieth century, little is widely known about his personal life, interests, and motivations. This book explores Darwins driving passion using Darwins own words from The Origin of Species, Autobiography, Voyage of the Beagle and letters. In retracing the roots of evolution from the Greeks, Darwin, Then and Now journeys through the dynamics of the eighteenth century that lead to the publication of The Origin of Species and the succeeding role of key players in the emerging evolution revolution. Darwin, Then and Now examines Darwins theory with more than three-hundred quotations from The Origin of Species, spotlighting what Darwin said concerning the origin of species and natural selection using the American Museum of Natural History Darwin exhibit format. With over one-thousand referenced quotations from scientists and historians, Darwin, Then and Now explores the scientific evidence over the past 150 years from the fossil record, molecular biology, embryology, and modern genetics.
