    On the many processes of chemical evolution.Christophe Malaterre - unknown
    The notion of chemical evolution is controversially defined in reference to Darwinian evolution: for some, it is nothing but natural selection applied to chemical systems; yet, for others, it is precisely what happened before natural selection, the latter being the birthmark of life. Taking into account a plurality of evolutionary processes, I propose to construe chemical evolution as a composite theory within which natural selection might only be one of several evolutionary processes.

    The belief in the Darwinian theory of evolution appeared to be shaken when one tried to interpret statements of molecular biology in it. As a consequence there arose a theory of non-Darwinian neutral evolution. The supporters of this theory believe that under natural conditions no factors exist which can distinguish and select organisms on their internal (molecular) structure. In the opinion of these neutralists natural selection cannot in principle control the molecular constitution of organisms. Contrary to the viewpoint (...)

    The chemical kinetics of molecular evolution.Paul Woolley - 1989 - Bioessays 10 (1):25-29.
    This article describes a current view of the events that initiated the transition from the rich organic and inorganic chemistry of the primitive Earth to the earliest forms of life. It is a personal condensation of the basic ideas developed in the so‐called Göttingen school. Most of these will be found in the seminal paper of Eigen1 and the other sources cited. A detailed exposition is given by Küppers2.

    Evolution of the Doctrine of Signatures of Things and the Adamic Language in the Chemical Philosophy of the 16th and 17th Centuries. [REVIEW]Anton V. Karabykov - 2020 - Russian Journal of Philosophical Sciences 63 (8):91-105.
    The aim of the paper is to investigate paths along which a transformation of the doctrine of natural signs was developed in works by Paracelsians, forming one of the main religious and philosophic currents of Late Renaissance. The modifications of the doctrine are discussed in a context of intensive speculations on the essence of the primordial language of humankind and on the possibility of its restoration, which can describe the intellectual life of that epoch. It is argued that within “ (...) philosophy” the possibility of restoration of the Adamic language directly depends on mastering the art of interpreting natural signs, which can give a key to correct understanding of nature. And shifts in the conceptualization of such signatures involved transformations in formulating and solving of the Adamistic problems, which did not exclude reverse causation. It is also ascertained that the most orthodox followers of Paracelsus usually appealed to the Adamistic narrative in order to reinforce legitimacy of the symbolic hermeneutics of nature, developed with chiefly medico-pharmacological purposes. Meanwhile, relatively more independent Paracelsians often paid more attention to linguo-philosophic issues. Realizing the deficiency of the doctrine of signatures for reconstruction of the primordial language, they postulated the necessity of one of the following premises: supplementing the doctrine with a mystical illumination; acceptance of a weaker version, according to which natural signs are just sparse reference points slightly simplifying empirical study of nature; abandonment of search for the Ursprache and constructing its artificial substitute, a universal semiotic system.

    Evolution and Religious Creation Myths: How Scientists Respond.Paul F. Lurquin & Linda Stone - 2007 - Oxford University Press USA.
    Polls show that 45% of the American public believes that humans were created about 10,000 years ago and that evolution is a fictitious myth. Another 25% believes that changes in the natural world are directed by a supernatural being with a particular goal in mind. This thinking clashes head on with scientific findings from the past 150 years, and there is a dearth of public critical thinking about the natural world within a scientific framework.

    A general definition of the concept of chemical speciation, chemical species transformation and chemical species evolution based on a semantics of meaning.Waldo Quiroz, Roberto Morales-Aguilar & Pablo A. Perez - forthcoming - Foundations of Chemistry:1-17.
    The concept of a “chemical speciation”, as defined by in the year 2000, is grounded in an empiricist semantics. It is a static concept, as it is associated with the ontological category of the chemical state of the distribution of chemical species in a system and is further restricted to chemical species of a single element as it excludes chemical species with more complex chemical systemic subunits, such as molecular species, crystals, or nanoparticles.

Springer. pp. 271-282.
    How the universe came to be what it is now is a key philosophical question. The hypothesis that it came from nothing or śūnya proves to be dissembling, since the quantum vacuum can hardly be considered a void. In modern science, it is generally assumed that matter existed before the universe came to be. Modern science hypothesizes that the manifestation of life on earth is nothing but a mere increment in the complexity of matter – and hence is an outcome (...)

    Self-reinforcing Mechanisms Driving the Evolution of the Chemical Space.Jürgen Jost & Guillermo Restrepo - 2023 - Perspectives on Science 31 (5):555-593.
    Chemistry is engaged with a subject that is not static but evolving in time, in chemical space, namely, the collection of all substances and reactions reported over time. If we accept that premise, we can identify the path dependencies and self-reinforcing mechanisms that determined its current space and selected it across historical alternatives. In particular, data analysis allows us to identify two crucial turning points. One was the introduction of structural theory in 1860, the other a technological shift around (...)

    The role of evolutionary theory at the origin of life is an extensively debated topic. The origin and early development of life is usually separated into a prebiotic phase and a protocellular phase, ultimately leading to the Last Universal Common Ancestor. Most likely, the Last Universal Common Ancestor was subject to Darwinian evolution, but the question remains to what extent Darwinian evolution applies to the prebiotic and protocellular phases. In this review, we reflect on the current status of (...)

    Self-medication behaviour is the use of natural materials or chemical substances to manipulate behaviour or alter the body’s response to parasites or pathogens. Self-medication can be preventive, performed before an individual becomes infected or diseased, and/or therapeutic, performed after an individual becomes infected or diseased. We summarized all available reports of self-medication in mammals and reconstructed its evolution. We found that reports of self-medication were restricted to eutherian mammals and evolved at least four times independently. Self-medication was most (...)

    Evolution of the Genetic Code: The Ribosome-Oriented Model.Marcello Barbieri - 2015 - Biological Theory 10 (4):301-310.
    There are currently three major theories on the origin and evolution of the genetic code: the stereochemical theory, the coevolution theory, and the error-minimization theory. The first two assume that the genetic code originated respectively from chemical affinities and from metabolic relationships between codons and amino acids. The error-minimization theory maintains that in primitive systems the apparatus of protein synthesis was extremely prone to errors, and postulates that the genetic code evolved in order to minimize the deleterious effects (...)

    Evolution, reproduction and autopoiesis.Francois Durand - 2017 - HTS Theological Studies 73 (3).
    The term autopoiesis was coined to describe the regenerating and self-maintaining chemical systems of cells. The term has subsequently been applied to many different fields, including sociology, systems theory and information systems. This theory postulates that an autopoietic unity is an organised network of processes that exists in a delimited space, which produces components which in turn continuously regenerate and create the network of processes that produced them. The Santiago Theory of Cognition grew from the Theory of Allopoiesis stating (...)

Yet from a contested existence before the First World War, chemical engineering had become one of the 'big four' engineering professions in Britain, and a major contributor to Western economies, by the end of the twentieth century. The subject had distinct national trajectories. In Britain - too long seen as shaped by American experiences (...)

    Evolution on a Restless Planet: Were Environmental Variability and Environmental Change Major Drivers of Human Evolution?Peter J. Richerson & Robert Boyd - unknown
    Two kinds of factors set the tempo and direction of organic and cultural evolution, those external to biotic evolutionary process, such as changes in the earth’s physical and chemical environments, and those internal to it, such as the time required for chance factors to lead lineages across adaptive valleys to a new niche space (Valentine 1985). The relative importance of these two sorts of processes is widely debated. Valentine (1973) argued that marine invertebrate diversity patterns responded to seafloor (...)

  36. How functional differentiation originated in prebiotic evolution.Argyris Arnellos & Álvaro Moreno - 2012 - Ludus Vitalis 20 (37):1-23.
    Even the simplest cell exhibits a high degree of functional differentiation (FD) realized through several mechanisms and devices contributing differently to its maintenance. Searching for the origin of FD, we briefly argue that the emergence of the respective organizational complexity cannot be the result of either natural selection (NS) or solely of the dynamics of simple self-maintaining (SM) systems. Accordingly, a highly gradual and cumulative process should have been necessary for the transition from either simple self-assembled or self-maintaining systems of (...)

    In this paper it is performed a historical account of the theoretical roots that grounded the following four key basic ideas of chemical equilibrium: ‘incomplete reaction’, ‘reversibility’, ‘equilibrium constant’ and ‘molecular dynamics’. These notions developed in nineteenth-century as a consequence of the evolution of the concept of chemical affinity. The discussion begins with the presentation of the earliest affinity table [‘Table des rapports’] published in 1718 by Geoffroy. Afterwards, it is examined Bergman’s compilation.

    Daniel R. Brooks and E. O. Wiley have proposed a theory of evolution in which fitness is merely a rate determining factor. Evolution is driven by non-equilibrium processes which increase the entropy and information content of species together. Evolution can occur without environmental selection, since increased complexity and organization result from the likely capture at the species level of random variations produced at the chemical level. Speciation can occur as the result of variation within the species (...)

    The origin and evolution of social insect queen pheromones: Novel hypotheses and outstanding problems.Cintia A. Oi, Jelle S. van Zweden, Ricardo C. Oliveira, Annette Van Oystaeyen, Fabio S. Nascimento & Tom Wenseleers - 2015 - Bioessays 37 (7):808-821.
    Queen pheromones, which signal the presence of a fertile queen and induce daughter workers to remain sterile, are considered to play a key role in regulating the reproductive division of labor of insect societies. Although queen pheromones were long thought to be highly taxon‐specific, recent studies have shown that structurally related long‐chain hydrocarbons act as conserved queen signals across several independently evolved lineages of social insects. These results imply that social insect queen pheromones are very ancient and likely derived from (...)

    Different Kinds of Evolution.J. Arthur Thomson - 1926 - Philosophy 1 (1):50.
    Evoluvation is one of the badly over worked words, like “ force,” “ instinct,” and “ value.” It means a process of Becoming. but it is applied to various orders of facts which have very little in common, either as regards the material evolving or in the way in which the evolution comes about. We hear of the evolution of a solar system, the evolution of matter, the evolution of religion, the evolution of the (...) elements, the evolution of man, the evolution of language, the evolution of scenery, the evolution of the horse, the evolution of mind, the evolution of plants, the evolution of sex, the evolution of society, the evolution of species, the evolution of evolution theories, and so on. When processes that are different are called by the same name, there is bound to be confusion; and it is more than verbal. We venture to make some simple suggestions which, if accepted, would lessen the confusion. (shrink)

They have "devoted most of their primary research efforts to discovering historical effects in developmental patterns." Finding that "such historical effects seem ubiquitous," they (...)

    Evolution in Biological and Non-biological Systems: The Origins of Life.Isaac Salazar-Ciudad - 2013 - Biological Theory 7 (1):26-37.
    A replicator is simply something that makes copies of itself. There are hypothetical replicators (e.g., self-catalyzing chemical cycles) that are suspected to be unable to exhibit heritable variation. Variation in any of their constituent molecules would not lead them to produce offspring with those new variant molecules. Copying, such as in DNA replication or in xerox machines, allows any sequence to be remade and then sequence variations to be inherited. This distinction has been used against non-RNA-world hypotheses: without RNA (...)

    Evolution and RNA Relics. A Systems Biology View.Jacques Demongeot, Nicolas Glade & Andrés Moreira - 2008 - Acta Biotheoretica 56 (1-2):5-25.
    The genetic code has evolved from its initial non-degenerate wobble version until reaching its present state of degeneracy. By using the stereochemical hypothesis, we revisit the problem of codon assignations to the synonymy classes of amino-acids. We obtain these classes with a simple classifier based on physico-chemical properties of nucleic bases, like hydrophobicity and molecular weight. Then we propose simple RNA ring structures that present, overlap included, one and only one codon by synonymy class as solutions of a combinatory (...)

    Anyone who has worked in Science for forty years can be much surprised to realize how little he now hears about evolution, compared with such former times. At present, evolution seems to be accepted as an axiomatic or universal principle, while the mechanism of it is not much considered, except by a small group of specialists, who work on the subject in greatly limited ways. This is practically a reversal of the former emphasis. The chemist would probably suggest (...)

    Heisenberg’s explanation of how two coupled oscillators exchange energy represented a dramatic success for his new matrix mechanics. As matrix mechanics transmuted into wave mechanics, resulting in what Heisenberg himself described as …an extraordinary broadening and enrichment of the formalism of the quantum theory , the term resonance also experienced a corresponding evolution. Heitler and London’s seminal application of wave mechanics to explain the quantum origins of the covalent bond, combined with Pauling’s characterization of the effect, introduced resonance into (...)
