It is widely acknowledged that life has adapted to its environment, but the precise mechanism remains unknown since Natural Selection, Descent with Modification and Survival of the Fittest are metaphors that cannot be scientifically tested. In this unique text, invertebrate and vertebrate biologists illuminate the effects of physiologic stress on epigenetic responses in the process of evolutionary adaptation from unicellular organisms to invertebrates and vertebrates, respectively. This book offers a novel perspective on the mechanisms underlying evolution. Capacities for morphologic alterations and epigenetic adaptations subject to environmental stresses are demonstrated in both unicellular and multicellular organisms. Furthermore, the underlying cellular-molecular mechanisms that mediate stress for adaptation will be elucidated wherever possible. These include examples of ‘reverse evolution’ by Professor Guex for Ammonites and for mammals by Professor Torday and Dr. Miller. This provides empiric evidence that the conventional way of thinking about evolution as unidirectional is incorrect, leaving open the possibility that it is determined by cell-cell interactions, not sexual selection and reproductive strategy. Rather, the process of evolution can be productively traced through the conservation of an identifiable set of First Principles of Physiology that began with the unicellular form and have been consistently maintained, as reflected by the return to the unicellular state over the course of the life cycle.

Now available in paper, this stimulating book concentrates on evolutionary change under environmental stress at levels ranging from the molecular to the biogeographic, with an emphasis on genetic aspects. This approach contrasts with most of the literature of evolutionary biology, as theemphasis here is upon the extreme end of the stress gradient in terms of resistance. Major topics in this interdisciplinary book include the concept of stress and its evolutionary and ecological importance; genetic variation in stress response and the effects of stress on genetic variation; and costs and trade-offs involving stress responses. An approach to stress resistance interms of energetics permits the development of links between genetics, ecology, physiology, and behaviour. The book concludes with applications concerning range expansions of species, conservation strategies, and pollution effects.

Most organisms and populations have to cope with hostile environments, threatening their existence. Their ability to respond phenotypically and genetically to these challenges and to evolve adaptive mechanisms is, therefore, crucial. The contributions to this book aim at understanding, from a evolutionary perspective, the impact of stress on biological systems. Scientists, applying different approaches spanning from the molecular and the protein level to individuals, populations and ecosystems, explore how organisms adapt to extreme environments, how stress changes genetic structure and affects life histories, how organisms cope with thermal stress through acclimation, and how environmental and genetic stress induce fluctuating asymmetry, shape selection pressure and cause extinction of populations. Finally, it discusses the role of stress in evolutionary change, from stress induced mutations and selection to speciation and evolution at the geological time scale. The book contains reviews and novel scientific results on the subject. It will be of interest to both researchers and graduate students and may serve as a text for graduate courses.

Today developmental and evolutionary biologists are focussing renewed attention on the developmental process--those genetic and cellular factors that influence variation in individual body shape or metabolism--in an attempt to better understand how evolutionary trends and patterns within individuals might be limited and controlled. In this important work, the author reviews the classical literature on embryology, morphogenesis, and paleontology, and presents recent genetic and molecular studies on development. The result is a unique perspective on a set of problems of fundamental importance to developmental and evolutionary biologists.

Consciousness is the key to understanding human existence. Many have attempted to determine the fundamental nature of consciousness based on deductive reasoning. In contrast to that, Consciousness-Based Evolution has exploited empiric evidence for the evolution of physiology from the unicell to man based on cell-cell communication as the origin of consciousness, each intermediary step representing an innate effort to maintain homeostasis by harnessing the energy flow initiated by The Big Bang. By tracing vertebrate evolution as development and phylogeny, focusing on specific emergent steps using a Bayesian approach, individual traits can be seen as exaptations of earlier ways in which existential threats were resolved over the course of evolution. You, the readers, are the beneficiary of those insights.

Quantum Mechanics, Cell-Cell Signaling, and Evolution offers a detailed accounting of the latest research and theorizing on the integration of quantum physics with biological action to produce a novel perspective on evolution. The book advocates for a paradigm shift towards understanding biology and medicine causally as predictive sciences, presenting quantum mechanics and physiology as vertically integrated. The author has taken a unique approach to the question of how and why evolution occurred. The account is based on extensive knowledge of lipid physical chemistry, and its role in the evolution of the lung under the influence of hormonal effects on structure and function. The title arranges lipid biochemistry and biophysics into an integrated explanation, guiding readers from the immersion of lipids in water as the origin of life, to lung surfactant in alveolar homeostasis, and leading to a new understanding of how consciousness interacts with the laws of nature. This volume argues for a novel understanding of evolutionary processes based on fundamental science and positions itself as seeking consilience among research disciplines. Starting from the origins of the cosmos, the author proceeds through nucleosynthesis and Endosymbiosis Theory, to finally describe consciousness in relation to natural law. Offers a novel account of evolutionary mechanisms integrating quantum mechanics and cell-cell signaling Presents the latest research and theorizing on the integration of quantum physics with biological action Grounds theoretical insights in lipid physical chemistry and the evolution of the lung Details an integrated, causal account of evolution operating across physical and biological domains Argues for a paradigm shift in the way evolution is understood

Cellular-molecular approach to evolution has led to radical changes in our understanding of biologic principles ranging from the Cell, to the Life Cycle, Development, Homeostasis, Senescence/Aging, Heterochrony, Pleiotropy, Phenotype, and perhaps the purpose of life itself. Much of this new way of thinking about biology and medicine emanates from experimental evidence for epigenetic inheritance. This leads one to question whether our unicellular state is the actual primary level of selection. One particular system that is now recognized as being under the auspices of epigenetic inheritance is the endocrine system, which is conventionally thought to regulate physiologic homeostasis. However, because the sex hormones play such a major role in behaviors related to the acquisition of epigenetic data, and the processing of such epigenetic data by the gonads during meiosis, their role in the evolution of the organism become tractable. The composite of the activities of the individual over the course of its lifetime can now be understood causally, resulting from the orchestration of its physiology by hormones, prenatally, postnatally and during the aging process, across the entire life span of the organism. Specific behaviors over the course of the life cycle during childhood, adolescence, puberty, adulthood and aging can now be understood mechanistically rather than merely as milestones in the various stages of life. With the above considerations in mind, this book presents the cellular-evolutionary perspective towards the relationship of the organism with its surroundings, human and non-human alike renders biology and medicine a continuum instead of fragmented, un-related anecdotes.

Cognition-Based Evolution is the first comprehensive alternative to 20th-century Neodarwinism, proposing a radical 21st-century evolutionary framework with a novel point of origination: all cells are intelligent and must measure uncertain environmental information to sustain themselves. In Cognition-Based Evolution, life is defined by cognition. From this differential stance, evolutionary biology transforms into the science of why, how, what, and with whom cells measure and communicate under stressful environmental conditions. Life's context is uncertain environmental information, communication is its means, and genes are its tools. Evolution is its yield as continuous non-random self-referential cellular problem-solving.

Understanding how simple molecules have given rise to the complex biochemical systems and processes of contemporary biology is widely regarded as one of chemistry’s great unsolved questions. There are numerous theories as to the origins of life, the majority of which draw on the idea that DNA and nucleic acids are the central dogma of biology. The Singularity of Nature: A Convergence of Biology, Chemistry and Physics takes a systems-based approach to the origin and evolution of complex life. Readers will gain a novel understanding of physiologic evolution and the limits to our current understanding: why biology remains descriptive and non-predictive, as well as offering new opportunities for understanding relationships between physics and biology in the origins of biological life at the cellular-molecular level.
