  1. Cancer Stem Cells Modulate Patterns and Processes of Evolution in Cancers.Lucie Laplane - 2018 - Biology and Philosophy 33 (3-4):18.
    The clonal evolution model and the cancer stem cell model are two independent models of cancers, yet recent data shows intersections between the two models. This article explores the impacts of the CSC model on the CE model. I show that CSC restriction, which depends on CSC frequency in cancer cell populations and on the probability of dedifferentiation of cancer non-stem cells into CSCs, can favor or impede some patterns of evolution and some processes of evolution. Taking CSC restriction into (...)

  • Drift Beyond Wright–Fisher.Hayley Clatterbuck - 2015 - Synthese 192 (11):3487-3507.
    Several recent arguments by philosophers of biology have challenged the traditional view that evolutionary factors, such as drift and selection, are genuine causes of evolutionary outcomes. In the case of drift, advocates of the statistical theory argue that drift is merely the sampling error inherent in the other stochastic processes of evolution and thus denotes a mathematical, rather than causal, feature of populations. This debate has largely centered around one particular model of drift, the Wright–Fisher model, and this has contributed (...)

  • Drift Sometimes Dominates Selection, and Vice Versa: A Reply to Clatterbuck, Sober and Lewontin.Robert Brandon & Leonore Fleming - 2014 - Biology and Philosophy 29 (4):577-585.
    Clatterbuck et al. (Biol Philos 28: 577–592, 2013) argue that there is no fact of the matter whether selection dominates drift or vice versa in any particular case of evolution. Their reasons are not empirically based; rather, they are purely conceptual. We show that their conceptual presuppositions are unmotivated, unnecessary and overly complex. We also show that their conclusion runs contrary to current biological practice. The solution is to recognize that evolution involves a probabilistic sampling process, and that drift is (...)
