How do new species evolve? Although Darwin identified inherited variation as the creative force in evolution, he never formally speculated where it comes from. His successors thought that new species arise from the gradual accumulation of random mutations of DNA. But despite its acceptance in every major textbook, there is no documented instance of it. Lynn Margulis and Dorion Sagan take a radically new approach to this question. They show that speciation events are not, in fact, rare or hard to observe. Genomes are acquired by infection, by feeding, and by other ecological associations, and then inherited. Acquiring Genomes is the first work to integrate and analyze the overwhelming mass of evidence for the role of bacterial and other symbioses in the creation of plant and animal diversity. It provides the most powerful explanation of speciation yet given.

An unusual visitor teaches a young college student a radical new sustainability paradigm in this lighthearted fable. From the smallest to the largest living systems, from cells and bacteria to the human body to ecosystems to the planet as a whole, readers will learn how it is all connected. For students of sustainability of all ages looking to envision a new Big Picture, The Life World explores very different assumptions about how evolution works in living systems. Just Three Principles of Life are used to accomplish this both simple and yet most challenging paradigm change. Not satisfied with outlining this new philosophy alone, the author tackles its application to the Florida Everglades, global warming, pollution, and human health.Prepare to be surprised.Prepare to see the world differently.Begin the work of true sustainability as a "W'ecologist."

This book provides a distinctive, radical way beyond the quarrels between evolutionary science and Christian belief. Leading scientists, philosophers, and theologians critically discuss the metaphysical assumptions of neo-Darwinism and offer concrete ways of broadening mainstream evolutionary theory. Their open exchange, moderated by veteran process theologian John B. Cobb, presents a holistic case for evolution that both theists and nontheists can accept. Contributors: Francisco J. Ayala Ian G. Barbour Charles Birch Philip Clayton John B. Cobb Jr. John Greene David Ray Griffin A. Y. Gunter John F. Haught Lynn Margulis Reg Morrison Dorion Sagan Jeffrey Schloss Robert J. Valenza Howard J.

This volume describes features of autonomy and integrates them into the recent discussion of factors in evolution. In recent years ideas about major transitions in evolution are undergoing a revolutionary change. They include questions about the origin of evolutionary innovation, their genetic and epigenetic background, the role of the phenotype and of changes in ontogenetic pathways. In the present book, it is argued that it is likewise necessary to question the properties of these innovations and what was qualitatively generated during the macroevolutionary transitions. The author states that a recurring central aspect of macroevolutionary innovations is an increase in individual organismal autonomy whereby it is emancipated from the environment with changes in its capacity for flexibility, self-regulation and self-control of behavior. The first chapters define the concept of autonomy and examine its history and its epistemological context. Later chapters demonstrate how changes in autonomy took place during the major evolutionary transitions and investigate the generation of organs and physiological systems. They synthesize material from various disciplines including zoology, comparative physiology, morphology, molecular biology, neurobiology and ethology. It is argued that the concept is also relevant for understanding the relation of the biological evolution of man to his cultural abilities. Finally the relation of autonomy to adaptation, niche construction, phenotypic plasticity and other factors and patterns in evolution is discussed. The text has a clear perspective from the context of systems biology, arguing that the generation of biological autonomy must be interpreted within an integrative systems approach.

If the objective of the Romantic movement was nothing less than to redefine the meaning of life itself, what role did experiments play in this movement? While earlier scholarship has established both the importance of science generally and vitalism specifically, with regard to Romanticism no study has investigated what it meant for artists to experiment and how those experiments related to their interest in the concept of life. Experimental Life draws on approaches and ideas from contemporary science studies, proposing the concept of experimental vitalism to show both how Romantic authors appropriated the concept of experimentation from the sciences and the impact of their appropriation on post-Romantic concepts of literature and art. Robert Mitchell navigates complex conceptual arenas such as network theory, gift exchange, paranoia, and biomedia and introduces new concepts, such as cryptogamia, chylopoietic discourse, trance-plantation, and the poetics of suspension. As a result, Experimental Life is a wide-ranging summation and extension of the current state of literary studies, the history of science, cultural critique, and theory.

Modern Biotechnology has potential for solving many problems associated with animal productivity and health and offers exciting opportunities for enhancing agricultural productivity. At present the focus is, however, on the issues and problems of significance for livestock producers in the developed world. In order to fully realize the benefits of this technology in developing countries, there is a need to identify, characterize and apply appropriate gene-based technologies for these regions. These proceedings present peer reviewed state-of-the-art papers describing the achievements in the areas of animal breeding and genetics, animal nutrition, animal health, and environment, ethics, safety, and regulatory aspects of gene-based technologies; achievements which could be realized using these modern scientific tools to maximise the benefits from the 'livestock revolution' that is taking place; and the constraints in the use of gene-based technologies and their specific research needs. This book will help in bridging the wide gap between developed and developing countries, in the development and use of gene-based technologies, and to elucidate the current and future roles of such technologies in the developing world. It is a good reference source for researchers, students and policy-makers alike.

Draw on the wit and wisdom of brilliant scientists to inspire your students as you teach them about a challenging area of biology. This teachers guide, which accompanies the DVD EVO: Ten Questions Everyone Should Ask About Evolution is structured around 10 fundamental questions about biological evolution. The teachers guide explores the DVD's commentary from some of the world's most well-known biologists, who gathered on the Galàpagos Islands during a World Summit on Evolution and were interviewed about everything from what evolution is to how it happens to why anyone should care. While the video from the natural world provides students with vivid examples of the ideas and processes the biologists describe, the classroom experiences further support and develop students understanding of a scientifically-supported theory and its applications. The rigourously structured teachers guide helps you maximise the video with lesson-by-lesson learning outcomes; thorough background; and guidance on preparing for and then leading the lesson from initial student engagement through evaluation. Engaging, easy to use, and authoritative, EVO Teachers Guide and its DVD are must-have resources.

In The Viral Network, Theresa MacPhail examines our collective fascination with and fear of viruses through the lens of the 2009 H1N1 pandemic. In April 2009, a novel strain of H1N1 influenza virus resulting from a combination of bird, swine, and human flu viruses emerged in Veracruz, Mexico. The Director-General of the World Health Organization (WHO) announced an official end to the pandemic in August 2010. Experts agree that the global death toll reached 284,500. The public health response to the pandemic was complicated by the simultaneous economic crisis and by the public scrutiny of official response in an atmosphere of widespread connectivity. MacPhail follows the H1N1 influenza virus’s trajectory through time and space in order to construct a three-dimensional picture of what happens when global public health comes down with a case of the flu. The Viral Network affords a rare look inside the U.S. Centers for Disease Control, as well as Hong Kong’s virology labs and Centre for Health Protection, during a pandemic. MacPhail looks at the day-to-day practices of virologists and epidemiologists to ask questions about the production of scientific knowledge, the construction of expertise, disease narratives, and the different "cultures" of public health in the United States, Europe, Hong Kong, and China. The chapters of the book move from the micro to the macro, from Hong Kong to Atlanta, from the lab to the WHO, from the pandemic past in 1918 to the future. The various historical, scientific, and cultural narratives about flu recounted in this book show how biological genes and cultural memes become interwoven in the stories we tell during a pandemic. Ultimately, MacPhail argues that the institution of global public health is as viral as the viruses it tracks, studies, and helps to contain or eradicate. The "global" is itself viral in nature.
