  1. Selection and the Extent of Explanatory Unification.Robert A. Skipper Jr - 1999 - Philosophy of Science 66 (3):209.
    According to Philip Kitcher, scientific unification is achieved via the derivation of numerous scientific statements from economies of argument schemata. I demonstrate that the unification of selection phenomena across domains in which it is claimed to occur--evolutionary biology, immunology and, speculatively, neurobiology--is unattainable on Kitcher's view. I then introduce an alternative method for rendering the desired unification based on the concept of a mechanism schema. I conclude that the gain in unification provided by the alternative account suggests that Kitcher's view (...)

    (Mis)Interpreting Mathematical Models: Drift as a Physical Process.Michael R. Dietrich, Robert A. Skipper Jr & Roberta L. Millstein - 2009 - Philosophy, Theory, and Practice in Biology 1 (20130604):e002.
    Recently, a number of philosophers of biology have endorsed views about random drift that, we will argue, rest on an implicit assumption that the meaning of concepts such as drift can be understood through an examination of the mathematical models in which drift appears. They also seem to implicitly assume that ontological questions about the causality of terms appearing in the models can be gleaned from the models alone. We will question these general assumptions by showing how the same equation (...)

  3. Naturalism, Explanation, and Identity.Thomas W. Polger & Robert A. Skipper - manuscript
    Some people believe that there is an “explanatory gap” between the facts of physics and certain other facts about the world—for example, facts about consciousness. The gap is presented as a challenge to any thoroughgoing naturalism or physicalism. We believe that advocates of the explanatory gap have some reasonable expectations that cannot be merely dismissed. We also believe that naturalistic thinkers have the resources to close the explanatory gap, but that they have not adequately explained how and why these resources (...)

    Manipulating Underdetermination in Scientific Controversy: The Case of the Molecular Clock.Michael R. Dietrich & Robert A. Skipper - 2007 - Perspectives on Science 15 (3):295-326.
    : Where there are cases of underdetermination in scientific controversies, such as the case of the molecular clock, scientists may direct the course and terms of dispute by playing off the multidimensional framework of theory evaluation. This is because assessment strategies themselves are underdetermined. Within the framework of assessment, there are a variety of trade-offs between different strategies as well as shifting emphases as specific strategies are given more or less weight in assessment situations. When a strategy is underdetermined, scientists (...)

    Population Genetics.Roberta L. Millstein & Robert A. Skipper - 2006 - In David L. Hull & Michael Ruse (eds.), The Cambridge Companion to the Philosophy of Biology. Cambridge University Press.
    Population genetics attempts to measure the influence of the causes of evolution, viz., mutation, migration, natural selection, and random genetic drift, by understanding the way those causes change the genetics of populations. But how does it accomplish this goal? After a short introduction, we begin in section (2) with a brief historical outline of the origins of population genetics. In section (3), we sketch the model theoretic structure of population genetics, providing the flavor of the ways in which population genetics (...)

    The Causal Crux of Selection.Robert Alan Skipper - 2001 - Behavioral and Brain Sciences 24 (3):556-556.
    Hull et al. make a direct connection between selection and replication. My view is that selection, at its causal crux, is not inherently connected to replication. I make plain the causal crux of selection, distinguishing it from replication. I discuss implications of my results for Hull et al.'s critique of Darden and Cain (1989).

    Perspectives on the Animal Mind.Robert A. Skipper - 2004 - Biology and Philosophy 19 (4):483-487.
    Charles Darwin was one of the first to propose a unified framework with which to understand human and animal behavior. The foundation of Darwin’s framework is his theory of descent with modification. What Darwin was convinced that theory allowed him to say about human and animal behavior is exemplified in the ‘continuity thesis.’ As Darwin put it, ‘there is a much wider interval in mental power between one of the lowest fishes, as a lamprey or lancelet, and one of the (...)
