    Variation, adaptation, heredity and fitness, constraints and affordances, speciation, and extinction form the building blocks of the (Neo-)Darwinian research program, and several of these have been called “Darwinian principles.” Here, we suggest that caution should be taken in calling these principles Darwinian because of the important role played by reticulate evolutionary mechanisms and processes in also bringing about these phenomena. Reticulate mechanisms and processes include symbiosis, symbiogenesis, lateral gene transfer, infective heredity mediated by genetic and organismal mobility, (...)

  3. Reticulate evolution underlies synergistic trait formation in human communities.Nathalie Gontier & Anton Sukhoverkhov - forthcoming - Evolutionary Anthropology.
    This paper investigates how reticulate evolution contributes to a better understanding of human sociocultural evolution in general, and community formation in particular. Reticulate evolution is evolution as it occurs by means of symbiosis, symbiogenesis, lateral gene transfer, infective heredity, and hybridization. From these mechanisms and processes, we mainly zoom in on symbiosis and we investigate how it underlies the rise of (1) human, plant, animal, and machine interactions typical of agriculture, animal husbandry, farming, and industrialization; (2) diet-microbiome (...)

  4. Multi-model approaches to phylogenetics: Implications for idealization.Aja Watkins - 2021 - Studies in History and Philosophy of Science Part A 90 (C):285-297.
    Phylogenetic models traditionally represent the history of life as having a strictly-branching tree structure. However, it is becoming increasingly clear that the history of life is often not strictly-branching; lateral gene transfer, endosymbiosis, and hybridization, for example, can all produce lateral branching events. There is thus motivation to allow phylogenetic models to have a reticulate structure. One proposal involves the reconciliation of genealogical discordance. Briefly, this method uses patterns of disagreement – discordance – between trees of (...)

  5. The evolution of the biological sciences.Nathalie Gontier - 2024 - In Nathalie Gontier, Andy Lock & Chris Sinha (eds.), The Oxford Handbook of Human Symbolic Evolution. OUP. pp. 3-25.
    This chapter introduces the main research schools and paradigms along which the field of evolutionary biology has been developing. Evolutionary thinking was originally founded upon the Neo-Darwinian paradigm that combines the teachings of traditional Darwinism with those of the Modern Synthesis. The Neo-Darwinian paradigm has since further diversified into the Micro-, Meso-, and Macroevolutionary schools, and it has also started to integrate the school of Ecology. Together, these schools establish the paradigm called Ecological Evolutionary Developmental Biology (Eco-Evo-Devo). A final school (...)

  6. Teleonomy as a problem of self-causation.Nathalie Gontier - forthcoming - Biological Journal of the Linnean Society 139:388–414.
    A theoretical framework is provided to explore teleonomy as a problem of self-causation, distinct from upward, downward and reticulate causation. Causality theories in biology are often formulated within hierarchy theories, where causation is conceptualized as running up or down the rungs of a ladder-like hierarchy or, more recently, as moving between multiple hierarchies. Research on the genealogy of cosmologies demonstrates that in addition to hierarchy theories, causality theories also depend upon ideas of time. This paper explores the roots and impact (...)

  8. Asexual organisms, identity and vertical gene transfer.Gunnar Babcock - 2020 - Studies in History and Philosophy of Science Part C: Studies in History and Philosophy of Biological and Biomedical Sciences 81:101265.
    This paper poses a problem for traditional phylogenetics: The identity of organisms that reproduce through fission can be understood in several different ways. This prompts questions about how to differentiate parent organisms from their offspring, making vertical gene transfer unclear. Differentiating between parents and offspring stems from what I call the identity problem. How the problem is resolved has implications for phylogenetic groupings. If the identity of a particular asexual organism persists through fission, the vertical lineage on a (...)

  10. Genetics, Epigenetics, Paragenetics: Getting Closer to Life.Bhakti Madhava Puri - 2014 - The Harmonizer.
    Gregor Mendel (1822-1884) was the first to explain that certain 'traits' were inherited in plants from one generation to the next. These would later become known as genes. Frederich Miescher in 1869 analyzed a substance from the nucleus of cells, which he therefore called nuclein. Further study of nuclein revealed that it contained elements like hydrogen, oxygen, nitrogen and phosphorous, with a specific ratio of nitrogen to phosphorous. Then in 1878 Albrecht Kossel determined that nuclein contained nucleic acid, from which (...)

  11. The gene as the unit of selection: a case of evolutive delusion.Armando Aranda-Anzaldo - 1997 - Ludus Vitalis 5 (9):91-120.
    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 addition (...)

    Understanding the dynamics of information is crucial to many areas of research, both inside and outside of philosophy. Using computer simulations of three kinds of information, germs, genes, and memes, we show that the mechanism of information transfer often swamps network structure in terms of its effects on both the dynamics and the fitness of the information. This insight has both obvious and subtle implications for a number of questions in philosophy, including questions about the nature of information, whether (...)

  13. Darwin Meets Dr. Frankenstein: Using the Drake Equation to Calculate the Probability of Volcanic Lightning’s Impact on Chemical Evolution.Petar Nurkić - 2022 - Belgrade Philosophical Annual 1 (35):49-68.
    Horizontal gene transfer (HGT) has been a paramount mechanism of interest in recent literature addressing the origins of biological evolution. However, research on lightning-triggered electroporation represents the innovative and still insufficiently grasped approach to HGT (Kotnik, 2013). On the other hand, prebiotic synthesis is a fundamental process for chemical evolution. Recently, the effects of volcanic lightning on nitrogen fixation and phosphate reduction have also been considered (NavarroGonzález and Segura, 2004). This paper aims to present a top-down approach to (...)

    A remarkable event occurred at the December 3, 2004, meeting of the U. S. President’s Council on Bioethics. Council member William Hurlbut, a physician and Consulting Professor in the Program in Human Biology at Stanford University, formally unveiled a proposal that he claimed would solve the ethical problems surrounding the extraction of stem cells from human embryos. The proposal would involve the creation of genetically defective embryos that “never rise to the level of integrated organismal existence essential to be designated (...)

Singer, Christopher Reade & Stephen Fisher (eds.), Proceedings, AAAI Fall Symposium on Complex Adaptive Systems: Energy, Information and Intelligence. AAAI Press.
    Beyond belief change and meme adoption, both genetics and infection have been spoken of in terms of information transfer. What we examine here, concentrating on the specific case of transfer between sub-networks, are the differences in network dynamics in these cases: the different network dynamics of germs, genes, and memes. Germs and memes, it turns out, exhibit a very different dynamics across networks. For infection, measured in terms of time to total infection, it is network type rather than (...)

    In a now classic paper published in 1991, Alberch introduced the concept of genotype–phenotype (G!P) mapping to provide a framework for a more sophisticated discussion of the integration between genetics and developmental biology that was then available. The advent of evo-devo first and of the genomic era later would seem to have superseded talk of transitions in phenotypic space and the like, central to Alberch’s approach. On the contrary, this paper shows that recent empirical and theoretical advances have only sharpened (...)

However, I disagree with the Buratovich hypothesis that the hierarchal transfer of ribosomal protein small unit (rps) genes from mitochondrial genomes to nuclear genomes indicates inbuilt Intelligent Design (ID) instead of neo-Darwinian mechanics, where inbuilt ID involves "purposeful forces that are wholly natural in their scope (...)

    Microbial biofilm created huge burden in treatment of both community and hospital infections. A biofilm is complex communities of bacteria attached to a surface or interface enclosed in an exopolysaccharide matrix and protected from unfavorable conditions such as presence of antibiotics, host defense or oxidative stresses. Biofilms are often considered hot spot for horizontal gene transfer among same or different bacterial species. Furthermore, bacteria with increased hydrophobicity facilitate biofilm formation by reducing repulsion between the extracellular matrix and the (...)

    Philosophical discussions of species have focused on multicellular, sexual animals and have often neglected to consider unicellular organisms like bacteria. This article begins to fill this gap by considering what species concepts, if any, apply neatly to the bacterial world. First, I argue that the biological species concept cannot be applied to bacteria because of the variable rates of genetic transfer between populations, depending in part on which gene type is prioritized. Second, I present a critique of phylogenetic (...)

    Ontologies are being developed throughout the biomedical sciences to address standardization, integration, classification and reasoning needs against the background of an increasingly data-driven research paradigm. In particular, ontologies facilitate the translation of basic research into benefits for the patient by making research results more discoverable and by facilitating knowledge transfer across disciplinary boundaries. Addressing and adequately treating mental illness is one of our most pressing public health challenges.

    In a shift of position that has gone largely unnoticed by the great majority of commentators, Thomas Kuhn's version of the incommensurability thesis underwent a major transformation over the last decade and a half of his life. In his later work, Kuhn argued that incommensurability is a relation of translation failure between local subsets of interdefined theoretical terms, which encapsulate the taxonomic structure of a theory. Incommensurability arises because it is impossible to transfer the natural categories employed within one (...)

    Scholarly opinions vary on what language is, how it evolved, and from where or what it evolved. Long considered uniquely human, today scholars argue for evolutionary continuity between human language and animal communication systems. But while it is generally recognized that language is an evolving communication system, scholars continue to debate from which species language evolved, and what behavioral and cognitive features are the precursors to human language. To understand the nature of protolanguage, some look for homologs in gene (...)

    The pandemic significantly raised the stakes for the translation of bioethics insights into policy. The novelty, range and sheer quantity of the ethical problems that needed to be addressed urgently within public policy were unprecedented and required high‐bandwidth two‐way transfer of insights between academic bioethics and policy. Countries such as the United Kingdom, which do not have a National Ethics Committee, faced particular challenges in how to facilitate this. This paper takes as a case study the brief career of (...)

    In this paper I present and evaluate van Inwagen’s famous Consequence Argument, as presented in An Essay on Free Will. The grounds for the incompatibility of freewill and determinism, as argued by van Inwagen, is dependent on our actions being logical consequences of events outside of our control. Particularly, his arguments depend upon, in one guise or another, the transference of the modal property of not being possibly rendered false through the logical consequence relation, i.e. the β-principle. I argue that, (...)

  26. 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 molecular (...)

    Among the many causes of an event, how do we distinguish the important ones? Are there ways to distinguish among causes on principled grounds that integrate both practical aims and objective knowledge? Psychologist Tania Lombrozo has suggested that causal explanations “identify factors that are ‘exportable’ in the sense that they are likely to subserve future prediction and intervention” (Lombrozo 2010, 327). Hence portable causes are more important precisely because they provide objective information to prediction and intervention as practical aims. However, (...)

    Practice of knowledge management is often characterized by obstacles to creation, distribution, and transfer of knowledge from specific groups of settings. Obstacles or constraints to attempts to constitute knowledge as an organizational resource have been previously dealt within the context of organizational learning perspectives; however, there still remain barriers toward making learning available and all-pervasive throughout organizations. This is often as a result of two important factors: (i) bureaucratic and hierarchical forms of organization; and (ii) owing to the situated (...)

Hypothalamic and ovarian GnRH mRNA and pituitary LH~ mRNA levels were determined by respective RNA-blot hybridizations, and ovarian GnRH and estradiol contents and serum LH levels were measured by respective radioimmunoassays. Three animal models such as 1) PMSG-treated, 2) PMSG and heG-treated immature rats and 3) proestrous stage of adult rats were used. Immature rats (25-days old) were administered with PMSG (10 iu) at 10:00 hand 48 h later with heG (10 iu) to induce ovulation. In the PMSG-injected model, hypothalamic GnRH mRNA levels were markedly augmented about 9-fold at 50 h, and pituitary LH mRNA 3-fold at 52 h after PMSG administration. Serum LH levels were increased to the preovulatory surge levels at 56 h, and ovarian GnRH mRNA levels were augmented 4-fold at 60 h after PMSG injection. Administration of heG also induced a marked enhancement in ovarian GnRH mRNA levels in comparison to the values shown in both intact and PMSGtreated rats at 52 hand 54 h, respectively. In the proestrous stage of normal adult rats, pituitary LH~ mRNA levels were peaked at 16:00 h. The preovulatory LH surge was evident at 4 h before increment in ovarian GnRH mRNA levels as shown in PMSG-treated rats. The present study clearly showed the sequential increase in hypothalamic GnRH mRNA, pituitary LH~ mRNA and ovarian GnRH mRNA levels, indicating that ovarian GnRH may play a possible role in the control of follicular maturation and the ovulation process.

  36. The Mathematical Theory of Categories in Biology and the Concept of Natural Equivalence in Robert Rosen.Franck Varenne - 2013 - Revue d'Histoire des Sciences 66 (1):167-197.
    The aim of this paper is to describe and analyze the epistemological justification of a proposal initially made by the biomathematician Robert Rosen in 1958. In this theoretical proposal, Rosen suggests using the mathematical concept of “category” and the correlative concept of “natural equivalence” in mathematical modeling applied to living beings. Our questions are the following: According to Rosen, to what extent does the mathematical notion of category give access to more “natural” formalisms in the modeling of living beings? Is (...)

    Since the beginning of time, the pre-biological and the biological world have seen a steady increase in complexity of form and function based on a process of combination and re-combination. The current modern synthesis of evolution known as the neo-Darwinian theory emphasises population genetics and does not explain satisfactorily all other occurrences of evolutionary novelty. The authors suggest that symbiosis and hybridisation and the more obscure processes such as polyploidy, chimerism and lateral transfer are mostly overlooked and not (...)

  40. 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 prevailing (...)

  41. Biological and linguistic diversity. Transdisciplinary explorations for a socioecology of languages.Albert Bastardas-Boada - 2002 - Diverscité Langues 7.
    As a sort of intellectual provocation and as a lateral thinking strategy for creativity, this chapter seeks to determine what the study of the dynamics of biodiversity can offer linguists. In recent years, the analogical equation "language = biological species" has become more widespread as a metaphorical source for conceptual renovation, and, at the same time, as a justification for the defense of language diversity. Language diversity would be protected in a way similar to the mobilization that has taken (...)

  42. Model for DNA and Protein Interactions and the Function of the Operator.Alfred Gierer - 1966 - Nature 212:1480-1481.
    The short paper introduces the concept of possible branches of double-stranded DNA (later sometimes called palindromes): Certain sequences of nucleotides may be followed, after a short unpaired stretch, by a complementary sequence in reversed order, such that each DNA strand can fold back on itself, and the DNA assumes a cruciform or tree-like structure. This is postulated to interact with regulatory proteins. -/- .

  43. Architecture and Deconstruction. The Case of Peter Eisenman and Bernard Tschumi.Cezary Wąs - 2015 - Dissertation, University of Wrocław
    Architecture and Deconstruction Case of Peter Eisenman and Bernard Tschumi -/- Introduction Towards deconstruction in architecture Intensive relations between philosophical deconstruction and architecture, which were present in the late 1980s and early 1990s, belong to the past and therefore may be described from a greater than before distance. Within these relations three basic variations can be distinguished: the first one, in which philosophy of deconstruction deals with architectural terms but does not interfere with real architecture, the second one, in which (...)

  44. Translating the Idiom of Oppression: A Genealogical Deconstruction of FIlipinization and the 19th Century Construction of the Modern Philippine Nation.Michael Roland Hernandez - 2019 - Dissertation, Ateneo de Manila University
    This doctoral thesis examines the phenomenon of Filipinization, specifically understood as the ideological construction of a “Filipino identity” or ‘Filipino subject-consciousness” within the highly determinate context provided by the Filipino ilustrado nationalists such as José Rizal, Marcelo H. del Pilar and their fellow propagandists inasmuch as it leads to the nineteenth (19th) century construction of the modern Philippine nation. Utilizing Jacques Derrida’s deconstructive thinking, this study undertakes a genealogical critique engaged on the concrete historical examination of what is meant by (...)

The Parc de La Villette in Paris in the context of the philosophy of chôra I Bernard Tschumi’s project of the Parc de La Villette could have won the competition and was implemented thanks to the political atmosphere that accompanied the victory of the left-wing candidate in the French presidential elections in 1981. François Mitterand’s revision of the political programme and the replacement of radical reforms with the construction of prestigious architectural objects (...)

  46. What is Life?Guenther Witzany - 2020 - Frontiers in Astronomy and Space Sciences 7:1-13.
    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 show (...)

  47. Exploring mouse trap history.Joachim L. Dagg - 2011 - Evolution Education and Outreach 4 (3):397-414.
    Since intelligent design (ID) advocates claimed the ubiquitous mouse trap as an example of systems that cannot have evolved, mouse trap history is doubly relevant to studying material culture. On the one hand, debunking ID claims about mouse traps and, by implication, also about other irreducibly complex systems has a high educational value. On the other hand, a case study of mouse trap history may contribute insights to the academic discussion about material culture evolution. Michael Behe argued that mouse traps (...)

  48. Ideal Types and the Historical Method.Gene Callahan - 2007 - Collingwood and British Idealism Studies 13 (1):53-68.
    A number of social theorists have contended that the essence of historical analysis is the employment of ideal types to comprehend past goings-on. But, while acknowledging that the study of history through ideal types can yield genuine insight, we may still ask if it represents the full emancipation of historical understanding from other modes of conceiving the past. This paper follows Michael Oakeshott's work on the philosophy of history in arguing that explaining the historical past by means of ideal types, (...)

  49. Comic Cure for Delusional Democracy: Plato's Republic.Gene Fendt - 2014 - Lanham, MD: Lexington Books.
    In this book, author Gene Fendt shows how Plato's Republic provides a liturgical purification for the political and psychic delusions of democratic readers, even as Socrates provides the same for his interlocutors at the festival of Bendis. Each of the several characters is analyzed in accord with Book Eight's 6 geometrically possible kinds of character showing how their answers and failures in the dialogue exhibit the particular kind of movement and blindness predictable for the type.

  50. Winch on Following a Rule: A Wittgensteinian Critique of Oakeshott.Gene Callahan - 2012 - Collingwood and British Idealism Studies 18 (2):167-175.
    Peter Winch famously critiqued Michael Oakeshott's view of human conduct. He argued that Oakeshott had missed the fact that truly human conduct is conduct that 'follows a rule.' This paper argues that, as is sometimes the case with Oakeshott, what seems, on the surface, to be a disagreement with another, somewhat compatible thinker about a matter of detail in some social theory in fact turns out to point to a deeper philosophical divide. In particular, I contend, Winch, as typical of (...)
