Book Description
Emphasizing the changes worked by circulation and copying, interpretation and debate, this book uses the case to explore how pictures succeed and fail, gain acceptance and spark controversy. It reveals how embryonic development was made a process that we can see, compare, and discuss, and how copying - usually dismissed as unoriginal

Book Description
"This brief textbook of human development covers the events of fertilization, gestation, and sex determination, followed by descriptions of the science of cloning, stem cells, and genome sequencing. The chapter covering the science is juxtaposed with a chapter discussing ethical questions that arise, such as when does life begin, should assisted reproductive technologies be regulated, and should parents be allowed to choose their child's sex"--Provided by publisher.

Book Description
Forms, Souls, and Embryos allows readers coming from different backgrounds to appreciate the depth and originality with which the Neoplatonists engaged with and responded to a number of philosophical questions central to human reproduction, including: What is the causal explanation of the embryo’s formation? How and to what extent are Platonic Forms involved? In what sense is a fetus ‘alive,’ and when does it become a human being? Where does the embryo’s soul come from, and how is it connected to its body? This is the first full-length study in English of this fascinating subject, and is a must-read for anyone interested in Neoplatonism or the history of medicine and embryology.

Book Description
Historically, philosophers of biology have tended to sidestep the problem of development by focusing primarily on evolutionary biology and, more recently, on molecular biology and genetics. Quite often too, development has been misunderstood as simply, or even primarily, a matter of gene activation and regulation. Nowadays a growing number of philosophers of science are focusing their analyses on the complexities of development, and in Embryology, Epigenesis and Evolution Jason Scott Robert explores the nature of development against current trends in biological theory and practice and looks at the interrelations between development and evolution (evo-devo), an area of resurgent biological interest. Clearly written, this book should be of interest to students and professionals in the philosophy of science and the philosophy of biology.

Book Description
Icons of Life tells the engrossing and provocative story of an early twentieth-century undertaking, the Carnegie Institution of Washington's project to collect thousands of embryos for scientific study. Lynn M. Morgan blends social analysis, sleuthing, and humor to trace the history of specimen collecting. In the process, she illuminates how a hundred-year-old scientific endeavor continues to be felt in today's fraught arena of maternal and fetal politics. Until the embryo collecting project-which she follows from the Johns Hopkins anatomy department, through Baltimore foundling homes, and all the way to China-most people had no idea what human embryos looked like. But by the 1950s, modern citizens saw in embryos an image of "ourselves unborn," and embryology had developed a biologically based story about how we came to be. Morgan explains how dead specimens paradoxically became icons of life, how embryos were generated as social artifacts separate from pregnant women, and how a fetus thwarted Gertrude Stein's medical career. By resurrecting a nearly forgotten scientific project, Morgan sheds light on the roots of a modern origin story and raises the still controversial issue of how we decide what embryos mean.

Book Description
Did Darwin see evolution as progressive, directed toward producing ever more advanced forms of life? Most contemporary scholars say no. In this challenge to prevailing views, Robert J. Richards says yes—and argues that current perspectives on Darwin and his theory are both ideologically motivated and scientifically unsound. This provocative new reading of Darwin goes directly to the origins of evolutionary theory. Unlike most contemporary biologists or historians and philosophers of science, Richards holds that Darwin did concern himself with the idea of progress, or telos, as he constructed his theory. Richards maintains that Darwin drew on the traditional embryological meanings of the terms "evolution" and "descent with modification." In the 1600s and 1700s, "evolution" referred to the embryological theory of preformation, the idea that the embryo exists as a miniature adult of its own species that simply grows, or evolves, during gestation. By the early 1800s, however, the idea of preformation had become the concept of evolutionary recapitulation, the idea that during its development an embryo passes through a series of stages, each the adult form of an ancestor species. Richards demonstrates that, for Darwin, embryological recapitulation provided a graphic model of how species evolve. If an embryo could be seen as successively taking the structures and forms of its ancestral species, then one could see the evolution of life itself as a succession of species, each transformed from its ancestor. Richards works with the Origin and other published and archival material to show that these embryological models were much on Darwin's mind as he considered the evidence for descent with modification. Why do so many modern researchers find these embryological roots of Darwin's theory so problematic? Richards argues that the current tendency to see evolution as a process that is not progressive and not teleological imposes perspectives on Darwin that incorrectly deny the clearly progressive heart of his embryological models and his evolutionary theory.

Book Description
"Glory to the science of embryology!" So Johannes Holtfreter closed his letter to this editor when he granted permission to publish his article in this volume. And glory there is: glory in the phenomenon of animals developing their complex morphologies from fertilized eggs, and glory in the efforts of a relatively small group of scientists to understand these wonderful events. Embryology is unique among the biological disciplines, for it denies the hegemony of the adult and sees value (indeed, more value) in the stages that lead up to the fully developed organism. It seeks the origin, and not merely the maintenance, of the body. And if embryology is the study of the embryo as seen over time, the history of embryology is a second-order derivative, seeing how the study of embryos changes over time. As Jane Oppenheimer pointed out, "Sci ence, like life itself, indeed like history, itself, is a historical phenomenon. It can build itself only out of its past. " Thus, there are several ways in which embryology and the history of embryology are similar. Each takes a current stage of a developing entity and seeks to explain the paths that brought it to its present condition. Indeed, embryology used to be called Entwicklungsgeschichte, the developmental history of the organism. Both embryology and its history interpret the interplay between internal factors and external agents in the causation of new processes and events.

Book Description
A thorough appreciation of the cellular, molecular and tissue changes which precede the birth of an animal is a fundamental requirement for understanding normal structural development and also abnormal processes which result in congenital defects. This textbook provides information relevant to many subjects taught in preclinical, paraclinical and clinical years. Early chapters describe and explain sequential events relating to the division, growth and differentiation of cells and to the formation of foetal membranes, implantation and placentation. Succeeding chapters trace the origin, growth, development and maturation of the major body systems. Age determination of the embryo and foetus is reviewed in a single chapter. Genetic, chromosomal and environmental factors which adversely affect pre-natal development are reviewed in the final chapter. A reading list at the end of each chapter offers additional sources of information on the topics discussed. Tables, flow diagrams and numerous hand-drawn illustrations provide information in a form which complements the concepts presented in the text. Key features: Written by a team which includes members with expertise in developmental anatomy, molecular biology and clinical aspects of veterinary medicine. The authors have extensive experience in the teaching of veterinary embryology and cognate subjects. Illustrations, hand-drawn by a veterinary graduate, are used extensively to explain organogenesis and system development. An explanatory glossary provides concise information on specialised terms used in the text. The index is designed for easy retrieval of information.
