"This is a clear and engagingly written book," declared Nature, "recommended certainly to nonspecialists, but also to developmental biologists." Its exploration of how single cells multiply and develop offers an accessible look at a difficult subject. Easy-to-understand descriptions of experimental studies offer fascinating insights into aging, cancer, regeneration, and evolution. 1993 edition.
Jane Maienschein examines how understanding of embryos evolved from the speculations of natural philosophers to bioengineering, with its life-enhancing therapies. She shows that research on embryos has always seemed promising to some but frightening to others, and makes the case that public understanding must be informed by scientific findings.
Developmental biology is at the core of all biology. This text emphasizes the principles and key developments in order to provide an approach and style that will appeal to students at all levels.
From a single cell - a fertilized egg - comes an elephant, a fly, or a human. How does this astonishing feat happen? How does the egg 'know' what to become? How does it divide into the different cells, the separate tissues, the brain, the fingernail - every tiniest detail of the growing foetus? These are the questions that the field of developmental biology seeks to answer. It is an area that is closely linked to genetics, evolution, and molecular biology. The processes are deeply rooted in evolutionary history; the information is held in genes whose vital timings in switching on and off is orchestrated by a host of proteins expressed by other genes. Timing is of the essence. Here, the distinguished developmental biologist Lewis Wolpert gives a concise account of what we now know about development, discussing the first vital steps of growth, the patterning created by Hox genes and the development of form, embryonic stem cells, the timing of gene expression and its management, chemical signalling, and growth. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.
The Triumph of the Necrophiles is the product of over forty years of research and is the most thorough, comprehensive, and penetrating critique of the mechanical worldview ever written. Modrow meticulously traces the prescientific sources of that worldview back to our Judeo-Christian heritage and to the metaphysics of Plato and Pythagoras. He documents that Plato was in fact a necrophile and that his metaphysics can best be understood as a sublimation of his necrophilia. He discusses the influence that Plato and Pythagoras had on Copernicus, Kepler and Galileo. He especially emphasizes how the necrophilic worldview of Plato essentially became the worldview of Galileo, Descartes, and other seventeenth- century thinkers. He also discusses how Newton’s worldview was shaped by his religious beliefs. Modrow contends that the mechanical worldview is totally at odds with every major scientific advance that has occurred since the mid nineteenth century. He painstakingly explains how and why these scientific advances discredit that worldview. He discusses the philosophical implications of the theory of evolution, the theory of relativity, quantum theory, Bell’s theorem, and Godel’s proof and presents an alternative worldview that is more consistent with current scientific knowledge. In a final chilling chapter, Modrow shows where the necrophilic worldview of Plato and his modern mechanistic followers are taking us.
Pictures from the past powerfully shape current views of the world. In books, television programs, and websites, new images appear alongside others that have survived from decades ago. Among the most famous are drawings of embryos by the Darwinist Ernst Haeckel in which humans and other vertebrates begin identical, then diverge toward their adult forms. But these icons of evolution are notorious, too: soon after their publication in 1868, a colleague alleged fraud, and Haeckel’s many enemies have repeated the charge ever since. His embryos nevertheless became a textbook staple until, in 1997, a biologist accused him again, and creationist advocates of intelligent design forced his figures out. How could the most controversial pictures in the history of science have become some of the most widely seen? In Haeckel’s Embryos, Nick Hopwood tells this extraordinary story in full for the first time. He tracks the drawings and the charges against them from their genesis in the nineteenth century to their continuing involvement in innovation in the present day, and from Germany to Britain and the United States. Emphasizing the changes worked by circulation and copying, interpretation and debate, Hopwood uses the case to explore how pictures succeed and fail, gain acceptance and spark controversy. Along the way, he reveals how embryonic development was made a process that we can see, compare, and discuss, and how copying—usually dismissed as unoriginal—can be creative, contested, and consequential. With a wealth of expertly contextualized illustrations, Haeckel’s Embryos recaptures the shocking novelty of pictures that enthralled schoolchildren and outraged priests, and highlights the remarkable ways these images kept on shaping knowledge as they aged.
Spanning eight decades and chronicling the wild ride of a Greek-American family through the vicissitudes of the twentieth century, Jeffrey Eugenides’ witty, exuberant novel on one level tells a traditional story about three generations of a fantastic, absurd, lovable immigrant family -- blessed and cursed with generous doses of tragedy and high comedy. But there’s a provocative twist. Cal, the narrator -- also Callie -- is a hermaphrodite. And the explanation for this takes us spooling back in time, through a breathtaking review of the twentieth century, to 1922, when the Turks sacked Smyrna and Callie’s grandparents fled for their lives. Back to a tiny village in Asia Minor where two lovers, and one rare genetic mutation, set our narrator’s life in motion. Middlesex is a grand, utterly original fable of crossed bloodlines, the intricacies of gender, and the deep, untidy promptings of desire. It’s a brilliant exploration of divided people, divided families, divided cities and nations -- the connected halves that make up ourselves and our world.
This book explores the links between food and human cultural and physical evolution. Each chapter begins by summarizing the basic knowledge in the field, discusses recent research results, and confirms or challenges established concepts, inviting new insight and provoking new questions. This book catalyzes discussion between scientists working on one side in food science and on the other side in biological and biomedical research.
