  1. Rate variation during molecular evolution: creationism and the cytochrome c molecular clock.R. Hofmann James - 2017 - Evolution: Education and Outreach 10 (1).
    Molecular clocks based upon amino acid sequences in proteins have played a major role in the clarification of evolutionary phylogenies. Creationist criticisms of these methods sometimes rely upon data that might initially seem to be paradoxical. For example, human cytochrome c differs from that of an alligator by 13 amino acids but differs by 14 amino acids from a much more closely related primate, Otolemur garnettii. The apparent anomaly is resolved by taking into consideration the variable substitution rate of (...)

  2. The fact of evolution: Implications for Science education.James R. Hofmann & Bruce H. Weber - 2003 - Science & Education 12 (8):729-760.
    Creationists who object to evolution in the science curriculum of public schools often cite Jonathan Well’s book Icons of Evolution in their support (Wells 2000). In the third chapter of his book Wells claims that neither paleontological nor molecular evidence supports the thesis that the history of life is an evolutionary process of descent from preexisting ancestors. We argue that Wells inappropriately relies upon ambiguities inherent in the term ‘Darwinian’ and the phrase ‘Darwin’s theory’. Furthermore, he does (...)

  4. Evolution of Genetic Information without Error Replication.Guenther Witzany - 2020 - In Theoretical Information Studies. Singapur: pp. 295-319.
    Darwinian evolutionary theory has two key terms, variations and biological selection, which finally lead to survival of the fittest variant. With the rise of molecular genetics, variations were explained as results of error replications out of the genetic master templates. For more than half a century, it has been accepted that new genetic information is mostly derived from random error-based events. But the error replication narrative has problems explaining the sudden emergence of new species, new phenotypic traits, and genome (...)

  5. Evolution of phenotypic plasticity: where are we going now?Massimo Pigliucci - 2005 - Trends in Ecology and Evolution 20 (9):481-486.
    The study of phenotypic plasticity has progressed significantly over the past few decades. We have moved from variation for plasticity being considered as a nuisance in evolutionary studies to it being the primary target of investigations that use an array of methods, including quantitative and molecular genetics, as well as of several approaches that model the evolution of plastic responses. Here, I consider some of the major aspects of research on phenotypic plasticity, assessing where progress has been made (...)

    This essay moves along broad lines from molecular biology to evolutionary biology and ecology to theology. Its objectives are to: 1) present some recent scientific findings in the emerging field of epigenetics that indicate that it is “the genome in context,” not genes per se, that are important in biological development and evolution; 2) show that this weakens the gene-centric neo-Darwinist explanation of evolution which, in fact, shares a certain preformationist orientation with intelligent design theory; 3) argue (...)

  7. Evolution's Arrow: the direction of evolution and the future of humanity.John E. Stewart - 2000 - Canberra: The Chapman Press.
    Evolution's Arrow argues that evolution is directional and progressive, and that this has major consequences for humanity. Without resort to teleology, the book demonstrates that evolution moves in the direction of producing cooperative organisations of greater scale and evolvability - evolution has organised molecular processes into cells, cells into organisms, and organisms into societies. The book founds this position on a new theory of the evolution of cooperation. It shows that self-interest at the level (...)

  9. From the "'logic of Molecular Syntax' to Molecular Pragmatism. Explanatory deficits in Manfred Eigen's concept of language and communication.Guenther Witzany - 1995 - Evolution and Cognition 2 (1):148-168.

The author of the present contribution demonstrates that this view of Manfred Eigen’s cannot be sufficiently substantiated and that it must be supplemented by an (...)

    The extent to which normal (nonmalignant) cells of the body can evolve through mutation and selection during the lifetime of the organism has been a major unresolved issue in evolutionary and developmental studies. On the one hand, stable multicellular individuality seems to depend on genetic homogeneity and suppression of evolutionary conflicts at the cellular level. On the other hand, the example of clonal selection of lymphocytes indicates that certain forms of somatic mutation and selection are concordant with the organism-level fitness. (...)

  11. Back to the future: Aristotle and molecular biology.Armando Aranda Anzaldo - 2007 - Ludus Vitalis 15 (28):195-198.
    The Aristotelian axiom that function follows form was beautifully instantiated in molecular biology by the discovery of DNA’s structure that immediately suggested how DNA might work as depository and vehicle for genetic information. However, later on molecular biology became infatuated with the gene that became the center of the universe. This gene-centered viewpoint is an obstacle for the emerging field of evo-devo aiming at finding the causal connections between evolution and biological development. Here it is argued that (...)

  12. On the Possibility of Constructive Neutral Evolution.Arlin Stoltzfus - 1999 - Journal of Molecular Evolution 49 (2):169-181.
    The neutral theory often is presented as a theory of "noise" or silent changes at an isolated "molecular level", relevant to marking the steady pace of divergence, but not to the origin of biological structure, function, or complexity. Nevertheless, precisely these issues can be addressed in neutral models, such as those elaborated here in regard to scrambled ciliate genes, gRNA-mediated RNA editing, the transition from self-splicing to spliceosomal splicing, and the retention of duplicate genes. All of these are instances (...)

    The unit of selection is the concept of that ‘something’ to which biologists refer when they speak of an adaptation as being ‘for the good of’ something. Darwin identified the organism as the unit of selection because for him the ‘struggle for existence’ was an issue among individuals. Later on it was suggested that, in order to understand the evolution of social behavior, it is necessary to argue that groups, and not individuals, are the units of selection. The last (...)

  14. Do we have a Theory of Evolution?Bhakti Madhava Puri - 2009 - Darwin Under Siege.
    The neo-Darwinian theory of genetic random mutation and Natural Selection, does nothing to explain speciation. Thus, what has been called "natural selection" has come under much scrutiny and critique in recent times. The problem is that natural selection requires the existence of a stable array of species from which selection can be made. So natural selection does not perform the speciation, only the selection after speciation has occurred. The activity of creating new species must therefore lie in the random mutations (...)

  15. Genetic, epigenetic and exogenetic information in development and evolution.Paul Edmund Griffiths - 2017 - Interface Focus 7 (5).
    The idea that development is the expression of information accumulated during evolution and that heredity is the transmission of this information is surprisingly hard to cash out in strict, scientific terms. This paper seeks to do so using the sense of information introduced by Francis Crick in his sequence hypothesis and central dogma of molecular biology. It focuses on Crick's idea of precise determination. This is analysed using an information-theoretic measure of causal specificity. This allows us to reconstruct (...)

    Natural selection [Darwin 1859] is perhaps the most important component of evolutionary theory, since it is the only known process that can bring about the adaptation of living organisms to their environments [Gould 2002]. And yet, its study is conceptually and methodologically complex, and much attention needs to be paid to a variety of phenomena that can limit the efficacy of selection [Antonovics 1976; Pigliucci and Kaplan 2000].

    In 1968, Motoo Kimura submitted a note to Nature entitled “Evolutionary Rate at the Molecular Level,” in which he proposed what has since become known as the neutral theory of molecular evolution. This is the view that the majority of evolutionary changes at the molecular level are caused by random drift of selectively neutral or nearly neutral alleles. Kimura was not proposing that random drift explains all evolutionary change. He does not challenge the view that natural (...)

    The neutral and nearly neutral theories of molecular evolution are sometimes characterized as theories about drift alone, where drift is described solely as an outcome, rather than a process. We argue, however, that both selection and drift, as causal processes, are integral parts of both theories. However, the nearly neutral theory explicitly recognizes alleles and/or molecular substitutions that, while engaging in weakly selected causal processes, exhibit outcomes thought to be characteristic of random drift. A narrow focus on (...)

    In searching for life in extraterrestrial space, it is essential to act based on an unequivocal definition of life. In the twentieth century, life was defined as cells that self-replicate, metabolize, and are open for mutations, without which genetic information would remain unchangeable, and evolution would be impossible. Current definitions of life derive from statistical mechanics, physics, and chemistry of the twentieth century in which life is considered to function machine like, ignoring a central role of communication. Recent observations (...)

  23. Mutationism and the Dual Causation of Evolutionary Change.Arlin Stoltzfus - 2006 - Evolution and Development 8 (3):304-317.
    The rediscovery of Mendel's laws a century ago launched the science that William Bateson called "genetics," and led to a new view of evolution combining selection, particulate inheritance, and the newly characterized phenomenon of "mutation." This "mutationist" view clashed with the earlier view of Darwin, and the later "Modern Synthesis," by allowing discontinuity, and by recognizing mutation (or more properly, mutation-and-altered-development) as a source of creativity, direction, and initiative. By the mid-20th century, the opposing Modern Synthesis view was a (...)

Over the past decade, however, biology has begun to witness the return of the organism as a fundamental explanatory concept. There are three major causes: (a) the realization that the Modern Synthesis does not provide a fully satisfactory understanding of evolution; (b) the growing awareness of the limits (...)

Recent empirical data on genetic code compositions and rearrangements by mobile genetic elements and non-coding RNAs, together with results of virus research and their role in evolution, does not really fit into these concepts and compel a (...)

    The concept of adaptation is employed in many fields such as biology, psychology, cognitive sciences, robotics, social sciences, even literacy and art,1 and its meaning varies quite evidently according to the particular research context in which it is applied. We expect to find a particularly rich catalogue of meanings within evolutionary biology, where adaptation has held a particularly central role since Darwin’s The Origin of Species (1859) throughout important epistemological shifts and scientific findings that enriched and diversified the concept. Accordingly, (...)

    In identifying intrinsic molecular chance and extrinsic adaptive pressures as the only causally relevant factors in the process of evolution, the theoretical perspective of the Modern Synthesis had a major impact on the perceived tenability of an ontology of dispositional properties. However, since the late 1970s, an increasing number of evolutionary biologists have challenged the descriptive and explanatory adequacy of this “chance alone, extrinsic only” understanding of evolutionary change. Because morphological studies of homology, convergence, and teratology have revealed (...)

    The theory of evolution, which provides the conceptual framework for all modern research in organismal biology and informs research in molecular bi- ology, has gone through several stages of expansion and refinement. Darwin and Wallace (1858) of course proposed the original idea, centering on the twin concepts of natural selection and common descent. Shortly thereafter, Wallace and August Weismann worked toward the complete elimination of any Lamarckian vestiges from the theory, leaning in particular on Weismann’s (1893) concept of (...)

    We characterize a type of functional explanation that addresses why a homologous trait originating deep in the evolutionary history of a group remains widespread and largely unchanged across the group’s lineages.

The concept of conserved function applies broadly to many biological domains, and we illustrate its importance using examples of molecular sequence alignments at the intersection of evolution and (...)

Nevertheless, this preposterous notion is supported on previous naive assumptions of contemporary biology that have already been falsified by recent results of research in genomics and molecular biology.

    Recent successes of systems biology clarified that biological functionality is multilevel. We point out that this fact makes it necessary to revise popular views about macromolecular functions and distinguish between local, physico-chemical and global, biological functions. Our analysis shows that physico-chemical functions are merely tools of biological functionality. This result sheds new light on the origin of cellular life, indicating that in evolutionary history, assignment of biological functions to cellular ingredients plays a crucial role.

    Ever since Darwin a great deal of the conceptual history of biology may be read as a struggle between two philosophical positions: reductionism and holism. On the one hand, we have the reductionist claim that evolution has to be understood in terms of changes at the fundamental causal level of the gene. As Richard Dawkins famously put it, organisms are just ‘lumbering robots’ in the service of their genetic masters. On the other hand, there is a long holistic tradition (...)

    We describe an approach to measuring biological information where ‘information’ is understood in the sense found in Francis Crick’s foundational contributions to molecular biology. Genes contain information in this sense, but so do epigenetic factors, as many biologists have recognized. The term ‘epigenetic’ is ambiguous, and we introduce a distinction between epigenetic and exogenetic inheritance to clarify one aspect of this ambiguity. These three heredity systems play complementary roles in supplying information for development. -/- We then consider the evolutionary (...)

    Bacteria do many things as organized populations. We have recently learned much about the molecular basis of intercellular communication among prokaryotes. Colonies display bacterial capacities for multicellular coordination which can be useful in nature where bacteria predominantly grow as films, chains, mats and colonies. E. coli colonies are organized into differentiated non-clonal populations and undergo complex morphogenesis. Multicellularity regulates many aspects of bacterial physiology, including DNA rearrangement systems. In some bacterial species, colony development involves swarming (active migration of cell (...)

Historically, Trembley’s discovery of Hydra regeneration in 1744 was the begin¬ning of developmental biology as we understand it, with passionate debates about preformation versus de novo generation, mechanisms versus organisms. In fact, seemingly conflicting bottom-up and top-down concepts are both required in combination to understand development. In modern terms, this (...)

  44. Estabelecimento da Gestação nos Animais.Emanuel Isaque Cordeiro da Silva - manuscript
    OBJETIVO A gestação nos mamíferos domésticos é um processo fisiológico que implica mudanças físicas, metabólicas e hormonais na fêmea, que culminam com o nascimento de um novo indivíduo. Desta forma, a compreensão de tais mudanças e como estas favorecem um ambiente ideal de desenvolvimento embrionário inicial, até a placentação e a fisiologia envolvidas durante esses processos é fundamental na tomada de decisões quanto à saúde reprodutiva da fêmea, na seleção de futuras matrizes e até mesmo para a saúde fetal e (...)

  45. From molecules to phenotypes? The promise and limits of integrative biology.Massimo Pigliucci - 2003 - Basic and Applied Ecology 4:297-306.
    Is integrative biology a good idea, or even possible? There has been much interest lately in the unifica- tion of biology and the integration of traditionally separate disciplines such as molecular and develop- mental biology on one hand, and ecology and evolutionary biology on the other. In this paper I ask if and under what circumstances such integration of efforts actually makes sense. I develop by example an analogy with Aristotle’s famous four “causes” that one can investigate concerning any (...)

  46. Marriages of Mathematics and Physics: A Challenge for Biology.Arezoo Islami & Giuseppe Longo - 2017 - Progress in Biophysics and Molecular Biology 131:179-192.
    The human attempts to access, measure and organize physical phenomena have led to a manifold construction of mathematical and physical spaces. We will survey the evolution of geometries from Euclid to the Algebraic Geometry of the 20th century. The role of Persian/Arabic Algebra in this transition and its Western symbolic development is emphasized. In this relation, we will also discuss changes in the ontological attitudes toward mathematics and its applications. Historically, the encounter of geometric and algebraic perspectives enriched the (...)

    Griffiths and Stotz’s Genetics and Philosophy: An Introduction offers a very good overview of scientific and philosophical issues raised by present-day genetics. Examining, in particular, the questions of how a “gene” should be defined and what a gene does from a causal point of view, the authors explore the different domains of the life sciences in which genetics has come to play a decisive role, from Mendelian genetics to molecular genetics, behavioural genetics, and evolution. In this review, I (...)

    The term “Complex Systems Biology” was introduced a few years ago [Kaneko, 2006] and, although not yet of widespread use, it seems particularly well suited to indicate an approach to biology which is well rooted in complex systems science. Although broad generalizations are always dangerous, it is safe to state that mainstream biology has been largely dominated by a gene-centric view in the last decades, due to the success of molecular biology. So the one gene - one trait approch, (...)

  49. "Life" shaped by genes that depend on their surrounds.Paul Gottlob Layer - 2011 - Annals of the History and Philosophy of Biology 16:153-170.
    Never was dogmatic reductionism helpful in conceiving the phenomenon of life. The post-genomic era has made it clear that genes alone cannot explain the functioning of whole organisms. Already each cell represents a unique, non-recurring individual. Recent progress in developmental biology has conveyed new perspectives both on the makings of individual organisms (ontogeny), as on evolutionary change (Evo-Devo). The genome (the entirety of all genes) of an animal remains constant from fertilization onwards in each cell. The realization of genes requires (...)

  50. A circular "basic space" as complement of space-time - an outcome of analogies between natural systems.Hans-Dieter Herrmann - manuscript
    Natural systems are categorized according to their structural and dynamical similarities. A two-dimensional schema is proposed as a kind of "periodic table" of natural systems. Six of eight levels in this schema serve as sources of analogies, two levels are the targets of analogical reasoning. The source domains are the atomic, molecular, macromolecular, micro-organismic, organismic and socio-cultural systems and processes. One of the target domains discussed in the article is the level of subatomic particles. The other target domain, not (...)
