    After the Double Helix.Angela N. H. Creager & Gregory J. Morgan - 2008 - Isis 99 (2):239-272.
    ABSTRACT Rosalind Franklin is best known for her informative X-ray diffraction patterns of DNA that provided vital clues for James Watson and Francis Crick's double-stranded helical model. Her scientific career did not end when she left the DNA work at King's College, however. In 1953 Franklin moved to J. D. Bernal's crystallography laboratory at Birkbeck College, where she shifted her focus to the three-dimensional structure of viruses, obtaining diffraction patterns of Tobacco mosaic virus (TMV) of unprecedented detail and clarity. During (...)

  4. Evolution without species: The case of mosaic bacteriophages.Gregory J. Morgan & W. Brad Pitts - 2008 - British Journal for the Philosophy of Science 59 (4):745-765.
    College of Medicine, University of South Alabama Mobile, AL 36688-0002, USA wbp501{at}jaguar1.usouthal.edu ' + u + '@' + d + ' '//--> Abstract Recent work in viral genomics has shown that bacteriophages exhibit a high degree of mosaicism, which is most likely due to a long history of prolific horizontal gene transfer (HGT). Given these findings, we argue that each of the most plausible attempts to properly classify bacteriophages into distinct species fail. Mayr's biological species concept fails because there is (...)

    Using Ethical Reasoning to Amplify the Reach and Resonance of Professional Codes of Conduct in Training Big Data Scientists.Rochelle E. Tractenberg, Andrew J. Russell, Gregory J. Morgan, Kevin T. FitzGerald, Jeff Collmann, Lee Vinsel, Michael Steinmann & Lisa M. Dolling - 2015 - Science and Engineering Ethics 21 (6):1485-1507.
    The use of Big Data—however the term is defined—involves a wide array of issues and stakeholders, thereby increasing numbers of complex decisions around issues including data acquisition, use, and sharing. Big Data is becoming a significant component of practice in an ever-increasing range of disciplines; however, since it is not a coherent “discipline” itself, specific codes of conduct for Big Data users and researchers do not exist. While many institutions have created, or will create, training opportunities to prepare people to (...)

  7. Laws of biological design: A reply to John Beatty.Gregory J. Morgan - 2010 - Biology and Philosophy 25 (3):379-389.
    In this paper, I argue against John Beatty’s position in his paper “The Evolutionary Contingency Thesis” by counterexample. Beatty argues that there are no distinctly biological laws because the outcomes of the evolutionary processes are contingent. I argue that the heart of the Caspar–Klug theory of virus structure—that spherical virus capsids consist of 60T subunits (where T = k 2 + hk + h 2 and h and k are integers)—is a distinctly biological law even if the existence of spherical (...)

    Evaluating Maclaurin and Sterelny’s conception of biodiversity in cases of frequent, promiscuous lateral gene transfer.Gregory J. Morgan - 2010 - Biology and Philosophy 25 (4):603-621.
    The recent conception of biodiversity proposed by James Maclaurin and Sterelny was developed mostly with macrobiological life in mind. They suggest that we measure biodiversity by dividing life into natural units (typically species) and quantifying the differences among units using phenetic rather than phylogenetic measures of distance. They identify problems in implementing quantitative phylogenetic notions of difference for non-prokaryotic species. I suggest that if we focus on microbiological life forms that engage in frequent, promiscuous lateral gene transfer (LGT), and their (...)

    Achinstein and Whewell on Theoretical Coherence.Gregory J. Morgan - 2011 - In Philosophy of Science Matters: The Philosophy of Peter Achinstein. , US: Oxford University Press. pp. 151.
    In his Particles and Waves, Peter Achinstein gives a precise probabilistic version of theoretical coherence inspired by William Whewell's somewhat vague notion of coherence. Whewell believed that as theoretical science proceeds, it becomes more coherent and rejects false incoherent theories. Achinstein offers a challenge: try to make Whewell's idea more precise while maintaining the properties that Whewell claimed coherence to have. This chapter argues (1) that Achinstein's probabilistic rendition of coherence fails to capture Whewell's notion since the probabilistic rendition of (...)

    Bacteriophage biology and Kenneth Schaffner's rendition of developmentalism.Gregory J. Morgan - 2001 - Biology and Philosophy 16 (1):85-92.
    In this paper I consider Kenneth Schaffner''s(1998) rendition of ''''developmentalism'''' from the point of viewof bacteriophage biology. I argue that the fact that a viablephage can be produced from purified DNA and host cellularcomponents lends some support to the anti-developmentalist, ifthey first show that one can draw a principled distinctionbetween genetic and environmental effects. The existence ofhost-controlled phage host range restriction supports thedevelopmentalist''s insistence on the parity of DNA andenvironment. However, in the case of bacteriophage, thedevelopmentalist stands on less firm (...)

    Making microbes matter: essay review of Maureen A. O’Malley’s Philosophy of Microbiology.Gregory J. Morgan, James Romph, Joshua L. Ross, Elizabeth Steward & Claire Szipszky - 2018 - Biology and Philosophy 33 (1-2):12.
    In a pioneering book, Philosophy of Microbiology, Maureen O’Malley argues for the philosophical importance of microbes through an examination of their impact on ecosystems, evolution, biological classification, collaborative behavior, and multicellular organisms. She identifies many understudied conceptual issues in the study of microbes. If philosophers follow her lead, the philosophy of biology will be expanded and enriched.

    The Value of Beauty in Theory Pursuit: Kuhn, Duhem, and Decision Theory.Gregory J. Morgan - 2013 - Open Journal of Philosophy 3 (1):9-14.
    Should judgments of beauty play a guiding role in theoretical science even if beauty is not a sign of truth? In this paper I argue that they should in certain cases. If we analyze the rationality of theoretical pursuit using decision theory, a theory’s beauty can influence the utilities of the various options confronting the researcher. After considering the views of Pierre Duhem and Thomas Kuhn on aesthetics in science, I suggest that because we value freedom of inquiry we rightly (...)

    Why there was a Useful Plausible Analogy between Geodesic Domes and Spherical Viruses.Gregory J. Morgan - 2006 - History and Philosophy of the Life Sciences 28 (2):215 - 235.
    In 1962, Donald Caspar and Aaron Klug published their classic theory of virus structure. They developed their theory with an explicit analogy between spherical viruses and Buckminster Fuller's geodesic domes. In this paper, I use the spherical virus-geodesic dome case to develop an account of analogy and deductive analogical inference based on the notion of an isomorphism. I also consider under what conditions there is a good reason to claim an experimentally untested analogy is plausible.
