  1. Equilibrium Explanation as Structural Non-Mechanistic Explanation: The Case Long-Term Bacterial Persistence in Human Hosts.Javier Suárez & Roger Deulofeu - 2019 - Teorema: International Journal of Philosophy 3 (38):95-120.
    Philippe Huneman has recently questioned the widespread application of mechanistic models of scientific explanation based on the existence of structural explanations, i.e. explanations that account for the phenomenon to be explained in virtue of the mathematical properties of the system where the phenomenon obtains, rather than in terms of the mechanisms that causally produce the phenomenon. Structural explanations are very diverse, including cases like explanations in terms of bowtie structures, in terms of the topological properties of the system, or in (...)

    What is a Hologenomic Adaptation? Emergent Individuality and Inter-Identity in Multispecies Systems.Javier Suárez & Vanessa Triviño - 2020 - Frontiers in Psychology 187 (11).
    Contemporary biological research has suggested that some host–microbiome multispecies systems (referred to as “holobionts”) can in certain circumstances evolve as unique biological individual, thus being a unit of selection in evolution. If this is so, then it is arguably the case that some biological adaptations have evolved at the level of the multispecies system, what we call hologenomic adaptations. However, no research has yet been devoted to investigating their nature, or how these adaptations can be distinguished from adaptations at the (...)

  3. The Hologenome Concept of Evolution: A Philosophical and Biological Study.Javier Suárez - 2019 - Dissertation, University of Exeter
    The hologenome concept of evolution is a hypothesis about the evolution of animals and plants. It asserts that the evolution of animals and plants was partially triggered by their interactions with their symbiotic microbiomes. In that vein, the hologenome concept posits that the holobiont (animal host + symbionts of the microbiome) is a unit of selection. -/- The hologenome concept has been severely criticized on the basis that selection on holobionts would only be possible if there were a tight transgenerational (...)

  4. The Importance of Symbiosis in Philosophy of Biology: An Analysis of the Current Debate on Biological Individuality and its Historical Roots.Javier Suárez - 2018 - Symbiosis 76 (2):77-96.
    Symbiosis plays a fundamental role in contemporary biology, as well as in recent thinking in philosophy of biology. The discovery of the importance and universality of symbiotic associations has brought new light to old debates in the field, including issues about the concept of biological individuality. An important aspect of these debates has been the formulation of the hologenome concept of evolution, the notion that holobionts are units of natural selection in evolution. This review examines the philosophical assumptions that underlie (...)

  5. A Metaphysical Approach to Holobiont Individuality: Holobionts as Emergent Individuals.Javier Suárez & Vanessa Triviño - 2019 - Quaderns de Filosofia 6 (1):59-76.
    Holobionts are symbiotic assemblages composed by a host plus its microbiome. The status of holobionts as individuals has recently been a subject of continuous controversy, which has given rise to two main positions: on the one hand, holobiont advocates argue that holobionts are biological individuals; on the other, holobiont detractors argue that they are just mere chimeras or ecological communities, but not individuals. Both parties in the dispute develop their arguments from the framework of the philosophy of biology, in terms (...)

    The stability of traits conception of the hologenome: An evolutionary account of holobiont individuality.Javier Suárez - 2020 - History and Philosophy of the Life Sciences 42 (1):1-27.
    Bourrat and Griffiths :33, 2018) have recently argued that most of the evidence presented by holobiont defenders to support the thesis that holobionts are evolutionary individuals is not to the point and is not even adequate to discriminate multispecies evolutionary individuals from other multispecies assemblages that would not be considered evolutionary individuals by most holobiont defenders. They further argue that an adequate criterion to distinguish the two categories is fitness alignment, presenting the notion of fitness boundedness as a criterion that (...)

  7. Explaining the Behaviour of Random Ecological Networks: The Stability of the Microbiome as a Case of Integrative Pluralism.Roger Deulofeu, Javier Suárez & Alberto Pérez-Cervera - forthcoming - Synthese:1-23.
    Explaining the behaviour of ecosystems is one of the key challenges for the biological sciences. Since 2000, new-mechanicism has been the main model to account for the nature of scientific explanation in biology. The universality of the new-mechanist view in biology has been however put into question due to the existence of explanations that account for some biological phenomena in terms of their mathematical properties (mathematical explanations). Supporters of mathematical explanation have argued that the explanation of the behaviour of ecosystems (...)

  8. When Mechanisms Are Not Enough: The Origin of Eukaryotes and Scientific Explanation.Roger Deulofeu & Javier Suárez - 2018 - In Alexander Christian, David Hommen, Gerhard Schurz & N. Retzlaff (eds.), Philosophy of Science. European Studies in Philosophy of Science, vol 9. Dordrecht, Netherlands: pp. 95-115.
    The appeal to mechanisms in scientific explanation is commonplace in contemporary philosophy of science. In short, mechanists argue that an explanation of a phenomenon consists of citing the mechanism that brings the phenomenon about. In this paper, we present an argument that challenges the universality of mechanistic explanation: in explanations of the contemporary features of the eukaryotic cell, biologists appeal to its symbiogenetic origin and therefore the notion of symbiogenesis plays the main explanatory role. We defend the notion that symbiogenesis (...)

    Bacterial Species Pluralism in the Light of Medicine and Endosymbiosis.Javier Suárez - 2016 - Theoria: Revista de Teoría, Historia y Fundamentos de la Ciencia 31 (1):91-105.
    This paper aims to offer a new argument in defence bacterial species pluralism. To do so, I shall first present the particular issues derived from the conflict between the non-theoretical understanding of species as units of classification and the theoretical comprehension of them as units of evolution. Secondly, I shall justify the necessity of the concept of species for the bacterial world, and show how medicine and endosymbiotic evolutionary theory make use of different concepts of bacterial species due to their (...)

    El mecanismo evolutivo de Margulis y los niveles de selección.Javier Suárez - 2016 - Contrastes: Revista Internacional de Filosofía 1 (20):7-26.
    Margulis’ evolutionary theory entails a revision of certain core concepts of traditional biology. One of these changes is related to the hot debate about units of selection. This paper considers Margulis’ proposal as a new research tradition (RT) and evaluates its consequences to the mentioned issue. Three ideas are suggested here: firstly, that her theory represents the revision of many classical biological concepts; secondly, that her position implies a reappraisal of many traditional issues in philosophy of biology; and thirdly, that (...)
