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.
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
“Deep time” is a term which attempts to capture temporal scales far beyond human comprehension. These are stretches of time epitomised by geological and cosmic scale processes, vast enough to make the entirety of human existence appear as little more than a footnote. The past few years have seen a boom in texts dedicated to the study of deep time, extending across a broad range of disciplines which fall markedly outside of its geological roots. These studies are unified by two ideas in particular: that deep time thinking and ecocriticism should be considered in conjunction, and that literature and the arts play a vital role in fostering a deep time awareness. Digressions in Deep Time is the first collection of essays which considers the multifarious representations of deep time across literature and the arts, assembling the work of a wide range of prominent scholars whose research frequently engages with temporality and ecocriticism. Featured contributions include work by the Pulitzer-prize winning author John McPhee, who popularised the term deep time in the late seventies, as well as chapters by Richard Irvine (author of An Anthropology of Deep Time), Benjamin Morgan (author of The Outward Mind) and Andrew Tate (author of Apocalyptic Fiction).
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.
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.
“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.
Unearthing the amazing hidden stories of women who changed paleontology forever. For centuries, women have played key roles in defining and developing the field of vertebrate paleontology. Yet very little is known about these important paleontologists, and the true impacts of their contributions have remained obscure. In Rebels, Scholars, Explorers, Annalisa Berta and Susan Turner celebrate the history of women "bone hunters," delving into their fascinating lives and work. At the same time, they explore how the discipline has shaped our understanding of the history of life on Earth. Berta and Turner begin by presenting readers with a review of the emergence of vertebrate paleontology as a science, emphasizing the contributions of women to research topics and employment. This is followed by brief biographical sketches and explanations of early discoveries by women around the world over the past 200 years, including those who who held roles as researchers, educators, curators, artists, and preparators. Forging new territory, Berta and Turner highlight the barriers and challenges faced by women paleontologists, describing how some managed to overcome those obstacles in order to build careers in the field. Finally, drawing on interviews with a diverse group of contemporary paleontologists, who share their experiences and offer recommendations to aspiring fossil hunters, they provide perspectives on what work still needs to be done in order to ensure that women's contributions to the field are encouraged and celebrated. Uncovering and relating lost stories about the pivotal contributions of women in vertebrate paleontology doesn't just make for enthralling storytelling, but also helps ensure a richer and more diverse future for this vibrant field. Illuminating the discoveries, collections, and studies of fossil vertebrates conducted by women in vertebrate paleontology, Rebels, Scholars, Explorers will be on every paleontologist's most-wanted list and should find a broader audience in the burgeoning sector of readers from all backgrounds eager to learn about women in the sciences.
From the Preface: The chapters of this book contain contributions from an international group of specialists. They address some important themes in both modern and ancient reef systems. Some chapters contain `snapshots' of reefs of particular intervals, while others touch on relevant themes of both modern and ancient reefs - themes that weave their way through reefs of all ages. This book opens and sets the stage with an introduction to both modern and ancient reefs and reef ecosystems. This chapter is also intended as a basic introduction for students, general geologists, and professionals or others who may be unfamiliar with reefs and reef ecosystems. The chapter addresses the living coral reef ecosystem, stressing among other relevant factors, the importance of ecological and physical interactions between the organisms and their environment. The chapter also addresses mass extinction and provides a general overview of the history of reefs.
[A] masterful survey. - Times Literary Supplement[A] concise ... extremely well-written journey about this planet''s history.... Highly recommended. - ChoiceIn a feat that may rival time travel, Burger has condensed 4.5 billion years into 294 eminently readable pages as he builds a case for solitude in our Milky Way galaxy. [Burger] writes with the clarity and humor of one who has had experience communicating complicated ideas to the lay public.-Boston GlobeFor many years the federal government funded the Search for Extraterrestrial Intelligence (SETI), later popularized by Carl Sagan''s novel Contact and the movie starring Jodie Foster. Though in actuality SETI never did make contact with signals from an alien civilization, the search continues to this day through privately funded endeavors. How likely is it that intelligent life exists elsewhere in the universe? This is the intriguing question that has prompted William Burger''s illuminating and absorbing exploration of the unusual circumstances surrounding life on earth.Examining the critical episodes in our planet''s early history and the peculiar trajectory of life on our world, Burger shows that the long odyssey of planet Earth may be utterly unique in our galaxy. For example, he describes features of the sun that are far from average. By some estimates, 95 percent of the other stars in the Milky Way galaxy are smaller, and it is unlikely that any of them could supply the energy requirements for a life-sustaining planet such as our own. Earth, as the third planet from the sun, sits within the Goldilocks orbit: it is in the perfect position to receive not too much heat (like Mercury and Venus) and not too little (like more distant planets of the solar system) but just the right amount to foster the development of life.Turning to the evolution of life itself, Burger points out a host of amazing accidents (for example, the extinction of dinosaurs and the proliferation of flowering plants) that make the steps along the way to Homo sapiens seem like very rare events indeed. He also calls attention to the curious fact that the early hominid brain tripled in size over the relatively short time period leading to the appearance of modern human beings. Finally, he notes aspects of humanity''s cultural evolution that seem unlikely to have been duplicated anywhere else.Burger''s enlightening evaluation of evolutionary and cosmic history, full of fascinating details, shows that the human achievement may be unique in our galaxy.More Praise for Perfect Planet, Clever Species:This is by far the best existing treatment of the SETI problem. Based on the most recent findings of science, it analyzes in full detail all the unique factors that would have to be right for success. Particularly fascinating is Burger''s critical study of the ten thousands of unpredictable steps in the evolution of Homo sapiens after the origin of life. A splendid history of mankind. - Ernst Mayr, Harvard UniversityI believe that this brilliant, richly documented and well-written book, on par in historical influence (or importance) with classics such as Rachel Carson''s Silent Spring, Paul Ehrlich''s The Population Bomb, E.O. Wilson''s On Human Nature or Sarah Blaffer''s Mother Nature, will go down as one of the most significant philosophical guides for us to follow as we stumble blindly into the 21st Century. - Hugh H. Iltis, Emeritus Botany Professor, University of Wisconsin-MadisonWith a lively narrative and at a headlong pace, Bill Burger leads us expertly from the origin of our planet through to the evolutionary history of humankind. Along the way, he repeatedly highlights the part played by chance occurrence of favourable conditions. Such contingency means that we can reconstruct our past but not predict our future. But we can address Burger''s central question: ''Are we alone?'' Soberingly, he builds up step-by-step to his conclusion.... The history of evolution on Earth is a compelling story in its own right and one tha
