These original contributions by symbiosis biologists and evolutionary theorists address the adequacy of the prevailing neo-Darwinian concept of evolution in the light of growing evidence that hereditary symbiosis, supplemented by the gradual accumulation of heritable mutation, results in the origin of new species and morphological novelty. A departure from mainstream biology, the idea of symbiosis—as in the genetic and metabolic interactions of the bacterial communities that became the earliest eukaryotes and eventually evolved into plants and animals—has attracted the attention of a growing number of scientists. These original contributions by symbiosis biologists and evolutionary theorists address the adequacy of the prevailing neo-Darwinian concept of evolution in the light of growing evidence that hereditary symbiosis, supplemented by the gradual accumulation of heritable mutation, results in the origin of new species and morphological novelty. They include reports of current research on the evolutionary consequences of symbiosis, the protracted physical association between organisms of different species. Among the issues considered are individuality and evolution, microbial symbioses, animal­bacterial symbioses, and the importance of symbiosis in cell evolution, ecology, and morphogenesis. Lynn Margulis, Distinguished Professor of Botany at the University of Massachusetts at Amherst, is the modern originator of the symbiotic theory of cell evolution. Once considered heresy, her ideas are now part of the microbiological revolution. Contributors Peter Atsatt, Richard C. Back, David Bermudes, Paola Bonfante-Fasolo, René Fester, Lynda J.

"François Jacob is one of the world's leading scientists, a professor of the Collège de France and the Institut Pasteur, and the winner of the Nobel Prize in Medicine (with André Lwoff and Jacques Monod). He has written an extraordinarily thought-provoking and far-ranging book on evolution which, as he states in his preface, "deals with genes and men, with sex, aging, and molecules. Above all, it deals with the theory of evolution, its status as well as its content. For if the theory of evolution provides a framework without which there is little hope to understand where we come from and why we are as we are, it is important to define the limits beyond which it is used no longer as a scientific theory, but as a myth.""--Back cover.

The significance of human individuality is such that each human functions as a unique "molecular" unit of the mass of humanity. Understanding the natural basis for the uniqueness of the individual has long been an objective. The possibilities have been analyzed by Julian Huxley, by A. E. Needham, by Roger Williams, and by others. With his books Biochemical Individuality and Free and Unequal, Roger Williams has done as much as anyone to focus atten tion on this complex of questions. Although scheduled to partici pate in this program, Roger Williams* was unable to attend due to illness. He asked, however, that a quotation be included in the proceedings. This quotation from Chraka is presented early in this book. While metabolic bases for individuality have received a con siderable investigation and discussion by Williams and others, the case for underlying determinants and derivative consequences have not been examined as fully. The specificities that abound in our living world can be traced to the manner in which molecules fit with each other. While numerous studies having other objectives can be cited in support of molecularly based specificities, a few of the leaders in the development of the understanding of physical aspects of biological information present here some of their latest inferences. Several of the participants discuss some of the conse quences at higher levels. Examination of the fascinating cases of reunited identical twins are seen as providing a capstone to the hierarchical treatment.

"When it comes to the phenomenon that is consciousness, there is one point on which scientists, philosophers, and artists all agree: that it feels like something to be us. Yet the fact we have subjective experience of the world remains one of nature's greatest mysteries. How is it that our mental operations are accompanied by feelings, thoughts, and a sense of self? What would a scientific investigation of our inner life look like, considering we have as little distance and perspective on it as fish do of the sea? In A World Appears, Michael Pollan traces the unmapped continent that is consciousness, bringing radically different perspectives-scientific, philosophical, literary, spiritual and psychedelic-to see what each can teach us about this central fact of life. When neuroscientists began studying consciousness in the early 1990s, they sought to explain how and why three pounds of spongy grey matter could generate a subjective point of view-assuming that the brain is the source of our felt reality. Pollan takes us to the cutting edge of the field, where scientists are entertaining more radical (and less materialist) theories of consciousness. He introduces us to "plant neurobiologists" searching for the first flicker of consciousness in plants; scientists striving to engineer feelings into AI, and psychologists and novelists seeking to capture the felt experience of our slippery stream of consciousness. In Pollan's dazzling exploration of consciousness, he discovers a world far deeper and stranger than our everyday reality. Eye-opening and mind-expanding, A World Appears takes us into the laboratories of our own minds, ultimately showing us how we might make better use of the gift of awareness to more meaningfully connect with our deepest selves"-- Provided by publisher.

Flowers evolved to attract pollinators, so new generations of plant can form. But how do plants know when to bloom, and how do they construct their flowers? This book describes what we have learnt of the astonishing genetic and epigenetic processes behind the dazzling variety of flower shapes, colours, and scents.--

"The newest addition to John Brockman's Edge.org series explores life itself, bringing together the world's leading biologists, geneticists, and evolutionary theorists -- including Richard Dawkins, Edward O. Wilson, J. Craig Venter, and Freeman Dyson. Scientists' understanding of life is progressing more rapidly than at any point in human history, from the extraordinary decoding of DNA to the controversial emergence of biotechnology. Featuring pioneering biologists, geneticists, physicists, and science writers, Life explains just how far we've come -- and takes a brilliantly educated guess at where we're heading. Richard Dawkins and J. Craig Venter compare genes to digital information, and sketch the frontiers of genomic research. Edward O. Wilson reveals what ants can teach us about building a superorganism -- and, in turn, about how cells build an organism. Elsewhere, David Haig reports new findings on how mothers and fathers individually influence the human genome, while Kary Mullis covers cutting edge treatments for dangerous viruses. And there's much more in this fascinating volume. We may never have all the answers. But the thinkers collected in Life are asking questions that will keep us dreaming for generations."--provided by Amazon.com.

Humanity is a part of Nature, yet every thinking person at one time or another asks herself or himself, "How did we get here? What makes me different from the rest of Nature?" In The Course of Nature an artist and a scientist ask those questions with full respect for all contexts, both scientific and not. Amy Pollack's figures stand on their own as elegant summaries of one or another aspect of Nature and our place in it. Robert Pollack's one-page essays for each illustration lay out the underlying scientific issues along with the overarching moral context for these issues. Together the authors have created a door into Nature for the non-scientist, and a door into the separate question of what is right, for both the scientist and the rest of us.

About forty thousand years ago, a new kind of hominid suddenly appeared in Europe and Western Asia. This was a creature unlike any of the other hominids then existing - borderline Homo sapiens, and the enigmatic Homo sapiens neanderthalensis.Seymour W. Itzkoff focuses in Triumph of the Intelligent on the evolutionary dynamics that led to the production of ever more intelligent humans, finally culminating in this sudden spasm of reconstruction. Itzkoff has followed the evidence carefully, attempting to stay within the assignable limits of evolutionary theory to produce a most-probable model of the dynamics that extruded this enigmatic creature, Homo sapiens sapiens.

Darwin provoked Jews as well as Christians, and this book examines leading nineteenth- and early twentieth-century American progressive Jewish thinkers who wrestled with evolutionary theories. In particular there was a widespread commitment to the application of biological evolutionary theory to history and cosmology, and a fascination with the evolution of ethical systems within human societies, bearing in mind mankind's bestial origins and new challenges for understanding religious traditions. It is argued that Reform Jewish discussions about the nature of God have been more profoundly shaped by engagement with evolutionary theory than has been recognized before and that, in fact, evolutionary thought provides the key conceptual framework for understanding the distinctive development of Reform Judaism in North America. --
