How can we bring together the study of genes, embryos and fossils? Embryos in Deep Time is a critical synthesis of the study of individual development in fossils. It brings together an up-to-date review of concepts from comparative anatomy, ecology and developmental genetics, and examples of different kinds of animals from diverse geological epochs and geographic areas. Can fossil embryos demonstrate evolutionary changes in reproductive modes? How have changes in ocean chemistry in the past affected the development of marine organisms? What can the microstructure of fossil bone and teeth reveal about maturation time, longevity and changes in growth phases? This book addresses these and other issues and documents with numerous examples and illustrations how fossils provide evidence not only of adult anatomy but also of the life history of individuals at different growth stages. The central topic of Biology today—the transformations occurring during the life of an organism and the mechanisms behind them—is addressed in an integrative manner for extinct animals.
Over the past decade, fossil finds from China have stunned the world, grabbing headlines and changing perceptions with a wealth of new discoveries. Many of these finds were first announced to English speakers in the journal Nature.Rise of the Dragon gathers together sixteen of these original reports, some augmented with commentaries originally published in Nature's "News and Views" section. Perhaps the best known of these new Chinese fossils are the famous feathered dinosaurs from Liaoning Province, which may help end one of the most intense debates in paleontology—whether birds evolved from dinosaurs. But other finds have been just as spectacular, such as the minutely preserved (to the cellular level) animal embryos of the 670 million-year-old Duoshantuo phosphorites, or the world's oldest known fish, from the Chengjiang formation in southwestern Yunnan Province. Rise of the Dragon makes descriptions and detailed discussions of these important finds available in one convenient volume for paleontologists and serious fossil fans.
“Three stories with a common theme: the female psyche, multiplied and divided,” says Greg Bear in his introduction to Women in Deep Time. “There’s probably something Jungian in common with all three. At any rate, throughout my writing career (and for whatever reason) I’ve been fascinated by the feminine voice.” Featured in this special collection are “Sisters,” Nebula Award finalist “Scattershot,” in which the inhabitants of many universes meet in limbo, and the Nebula Award–winning “Hardfought,” in which engineered warriors redefine humanity.
This long awaited core textbook in the study of evolution takes a similar approach to the subject as Roger Lewin's classic text, Human Evolution, but goes a step further. The many important discoveries and new evidence that have emerged since the last edition make this book a timely and necessary addition to any introductory evolution course."
A uniquely accessible way of looking at recent major advances in the science of embryonic development
Part memoir, part guide, this personal and deeply informative account of one woman’s gripping journey through the global fertility industry in search of the solution to her own “unexplained infertility” exposes eye-opening information about the medical, financial, legal, scientific, emotional and ethical issues at stake. Although conception may seem like a simple biological process, this is often hardly the case. While many would like to have children, the road toward conceiving and maintaining a pregnancy can be unexpectedly rocky and winding. Lawyer Elizabeth Katkin never imagined her quest for children would ultimately involve seven miscarriages, eight fresh IVF cycles, two frozen IVF attempts, five natural pregnancies, four IVF pregnancies, ten doctors, six countries, two potential surrogates, nine years, and roughly $200,000. Despite her three Ivy League degrees and wealth of resources, Katkin found she was woefully undereducated when it came to understanding and confronting her own difficulties having children. Shattered by her inability to get and stay pregnant, Katkin surprised even herself by her determination to keep trying. After being told by four doctors she should give up, but without an explanation as to what exactly was going wrong with her body, Katkin decided to look for answers herself. The global investigation that followed revealed that approaches to the fertility process taken in many foreign countries are vastly different than those in the US and UK. In Conceivability, Elizabeth Katkin, now a mother of two, shares her fertility journey. Part memoir, part practical guide—with a foreword by founder of New York Fertility Services Dr. Joel Batzofin—Conceivability sheds light on the often murky and baffling world of conception science, presenting a shocking exposé into the practical and emotional journey toward creating a happy family. Armed with a wealth of knowledge from her years-long fertility struggle, as well as stories from other women and couples, Katkin bravely offers a look inside one of the most difficult, painful, rewarding, and loving journeys a woman can take.
Why is the universe conscious? What kindles mind inside matter? Why do fundamentalist sciences and religions never ask these questions? This sequel to Embryogenesis deals with the theoretical issues brought up by Embryogenesis, including: the relationship between thermodynamics/entropy and the emergence of life; a speculative set of embryogenic principles for all creatures on all planets in the cosmos; an explanation and critique of Intelligent Design and a proposal for a more dynamic psychospiritual theory of creature development; a series of alternatives to genetic determinism; a discussion of the relationship between consciousness and matter; an interjection of 9/11 (which occurred during the writing of this book); and many other topics. Chapters include: What is Life?: Evolution, Thermodynamics, and Complexity; Is There a Plan?: Creationism, Cultural Relativism, and Paraphysics; Biogenesis and Cosmogenesis: Cells, Genes, and Planets; The Principles of Biological Design: Physical Forces in Nature; The Dynamics of the Biosphere: Deep Time and Space; The Limits of Genetic Determinism: Dimensionless Epigenetic Landscapes; Topokinesis: Physical Forces in Development; Tissue Motifs and Body Plans: Coordinating Form; The Primordial Field: Metabiology and The Molecular Apparatus; Meaning and Destiny: The Relation of Consciousness to Matter
"A subject collection from Cold Spring Harbor perspectives in biology."
Since the publication in 1859 of Darwin’s Origin of Species, debate over the theory of evolution has been continuous and often impassioned. In recent years, opponents of "Darwin’s dangerous idea" have mounted history’s most sophisticated and generously funded attack, claiming that evolution is "a theory in crisis." Ironically, these claims are being made at a time when the explosion of information from genome projects has revealed the most compelling and overwhelming evidence of evolution ever discovered. Much of the latest evidence of human evolution comes not from our genes, but from so-called "junk DNA," leftover relics of our evolutionary history that make up the vast majority of our DNA. Relics of Eden explores this powerful DNA-based evidence of human evolution. The "relics" are the millions of functionally useless but scientifically informative remnants of our evolutionary ancestry trapped in the DNA of every person on the planet. For example, the analysis of the chimpanzee and Rhesus monkey genomes shows indisputable evidence of the human evolutionary relationship with other primates. Over 95 percent of our genome is identical with that of chimpanzees and we also have a good deal in common with other animal species. Author Daniel J. Fairbanks also discusses what DNA analysis reveals about where humans originated. The diversity of DNA sequences repeatedly confirms the archeological evidence that humans originated in sub-Saharan Africa (the "Eden" of the title) and from there migrated through the Middle East and Asia to Europe, Australia, and the Americas. In conclusion, Fairbanks confronts the supposed dichotomy between evolution and religion, arguing that both science and religion are complementary ways to seek truth. He appeals to the vast majority of Americans who hold religious convictions not to be fooled by the pseudoscience of Creationists and Intelligent Design advocates and to abandon the false dichotomy between religion and real science. This concise, very readable presentation of recent genetic research is completely accessible to the nonspecialist and makes for enlightening and fascinating reading.
Human embryo research touches upon strongly felt moral convictions, and it raises such deep questions about the promise and perils of scientific progress that debate over its development has become a moral and political imperative. From in vitro fertilization to embryonic stem cell research, cloning, and gene editing, Americans have repeatedly struggled with how to define the moral status of the human embryo, whether to limit its experimental uses, and how to contend with sharply divided public moral perspectives on governing science. Experiments in Democracy presents a history of American debates over human embryo research from the late 1960s to the present, exploring their crucial role in shaping norms, practices, and institutions of deliberation governing the ethical challenges of modern bioscience. J. Benjamin Hurlbut details how scientists, bioethicists, policymakers, and other public figures have attempted to answer a question of great consequence: how should the public reason about aspects of science and technology that effect fundamental dimensions of human life? Through a study of one of the most significant science policy controversies in the history of the United States, Experiments in Democracy paints a portrait of the complex relationship between science and democracy, and of U.S. society's evolving approaches to evaluating and governing science's most challenging breakthroughs.
First published in 1959, this book describes the Western history of embryology from prehistoric concepts of foetal growth to the close of the eighteenth century.
This book provides a comprehensive overview of topics describing the earliest steps of fertilization, from egg activation and fertilization to the activation of the zygotic genome, in various studied vertebrate model systems. The contribution of maternal and paternal factors and their role in the early embryo as parental DNA becomes modified and embryonic genes become activated is fundamental to the initiation of embryogenesis in all animal systems. It can be argued that this is a unique developmental period, when information from the parents is compressed to direct the development of the body plan of the entire organism, a process of astounding simplicity, elegance and beauty. In addition to their fundamental scientific interest, many frontiers of biomedicine, such as reproductive biology, stem cells and reprogramming, and the understanding of intergenerational diseases, depend on advances in our knowledge of these early processes. Vertebrate Development: Maternal to Zygotic Control brings together chapters from experts in various disciplines describing the latest advances related to this important developmental transition. Each chapter is a synthesis of knowledge relevant to all vertebrates, with details on specific systems as well as comparisons between the various studied vertebrate models. The editorial expertise encompasses the fields of major vertebrate model systems (mammalian, amphibian and teleost) ensuring a balanced approach to various topics. This unique book—with its combination of in-depth and up-to-date basic research, inter-species comprehensiveness and emphasis on the very early stages of animal development—is essential for research scientists studying vertebrate development, as well as being a valuable resource for college educators teaching advanced courses in developmental biology.
The book describes the journey into the growing arena of clinical stem cell therapy by highlighting not only the road that brought a team of physicians together but also real stories from a number of their patients that were given their health back through the magic of stem cell therapy. Your fat is loaded with stem cells that can be used now to treat and reverse a large number of inflammatory and degenerative conditions. Most people have no idea that these magical cells actually exist right within our bodies. They think that they must wait until Big Pharma or a university PhD manufactures them from embryos. Yet the Cell Surgical Network, under the guidance of Drs. Berman and Lander, has been gathering investigational data that shows your cells are safe and effective in a large variety of clinical conditions. Almost any condition caused by damage or degradation of your own body cells has the potential for being improved using stem cells. And the potential actually exists to use your own cells to extend your life in a healthy, functional manner. The stem cell revolution train has left the station.
Every life has a soundtrack. All you have to do is listen. Music has set the tone for most of Zoe Baxter’s life. There’s the melody that reminds her of the summer she spent rubbing baby oil on her stomach in pursuit of the perfect tan. A dance beat that makes her think of using a fake ID to slip into a nightclub. A dirge that marked the years she spent trying to get pregnant. For better or for worse, music is the language of memory. It is also the language of love. In the aftermath of a series of personal tragedies, Zoe throws herself into her career as a music therapist. When an unexpected friendship slowly blossoms into love, she makes plans for a new life, but to her shock and inevitable rage, some people—even those she loves and trusts most—don’t want that to happen. Sing You Home is about identity, love, marriage, and parenthood. It’s about people wanting to do the right thing for the greater good, even as they work to fulfill their own personal desires and dreams. And it’s about what happens when the outside world brutally calls into question the very thing closest to our hearts: family.

This book is an easily accessible account of the nature and function of the human embryo. It answers such questions as: How do embryos develop? When can the life of 'a person' be said to begin? What are the main inherited defects in development? Can these be prevented or cured by genetic engineering? Is it possible to make human chimaeras, hybrids, parthenogenones, and clones? How can we overcome human infertility? How are test-tube babies made? What are the moral, ethical, and legal problems in this kind of work? With increasing debate over issues of abortion and reproductive medicine, this book will be of interest to anyone concerned with the fate of the human fetus.
Recent developments in biotechnology and genetic research are raising complex ethical questions concerning the legitimate scope and limits of genetic intervention. As we begin to contemplate the possibility of intervening in the human genome to prevent diseases, we cannot help but feel that the human species might soon be able to take its biological evolution in its own hands. 'Playing God' is the metaphor commonly used for this self-transformation of the species, which, it seems, might soon be within our grasp. In this important new book, Jurgen Habermas - the most influential philosopher and social thinker in Germany today - takes up the question of genetic engineering and its ethical implications and subjects it to careful philosophical scrutiny. His analysis is guided by the view that genetic manipulation is bound up with the identity and self-understanding of the species. We cannot rule out the possibility that knowledge of one's own hereditary factors may prove to be restrictive for the choice of an individual's way of life and may undermine the symmetrical relations between free and equal human beings. In the concluding chapter - which was delivered as a lecture on receiving the Peace Prize of the German Book Trade for 2001 - Habermas broadens the discussion to examine the tension between science and religion in the modern world, a tension which exploded, with such tragic violence, on September 11th.
A concise overview of genetics, evolution, and cellular processes, written by a winner of the Nobel Prize in Medicine, offers insight into the microscopic world of cells, addresses historical and contemporary questions, and discusses current ethical issues in the field of human biology.
