Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Environmental Stress Adaptation and Evolution written by Rudolf Bijlsma and published by Springer Science & Business Media. This book was released on 1997-09-23 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Consciousness Based Evolution written by John S. Torday and published by CRC Press. This book was released on 2023-12-01 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Cognition Based Evolution written by William B. Miller and published by CRC Press. This book was released on 2023-06-23 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Quantum Mechanics Cell Cell Signaling and Evolution written by John S. Torday and published by Elsevier. This book was released on 2022-09-09 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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
Download or read book Hormones and Reality written by John S. Torday and published by Springer Nature. This book was released on 2022-04-08 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book The Singularity of Nature written by John S Torday and published by Royal Society of Chemistry. This book was released on 2020-11-26 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: "Life emprisons stress and puts it to work. It often does so by symbiosis. Struggle is a property of life. This book presents Life as a struggle to bring the order of Mendel's Laws of heredity. The physical world tends to run out of useful energy like an old-fashioned clock. The secret of Life is, that it brings order where useful energy has gone, by a process called adaptation. This struggle of life so fashions biodiversity at all levels. Many decades of long-term experiments in test-tubes, long-term study of oceans and climates and forest ecosystem research allowed the authors to compare adaptation of life, from submicroscopic nucleotides to huge ecosystems. The sun's atomic clock beats the rhythm of environmental stress. Behaviour, rhythm and architecture were studied and explained at all levels, from molecule to plant or animal and to ecosystems. All evolution in Life follows pathways of a few steps only, joined by `biological clasps '. A clasp is like a coded biological lock at the end of a chain. A clasp opens or closes each half-path around the DNA helix., A meristem-with-leaf ('leaf-plus') opens or closes the pathway of shoot growth in plants, a ` minimal axis ' allows or blocks branching, perhaps ` homeotic genes ' in animals possess clasps. ` Critical eco-units ' stop or start ecosystem succession. Adaptation to stress requires a change of the code of the lock, that is a changed clasp, and so produces new instructions for new, adapted development. Codes are changed by plasmid transfer in DNA, meristem differentiation in plants, selective activation of seeds and eggs in mini-ecosystems. The sheer number of processes causes development to be complex and fuzzy. The struggle of Life has no mechanical precision. It creates similar but not quite the same, new, unexpected, diverse places for new, diverse structures and organisms to grow."--Site web www.nhbs.com.
