    Random sampling (drift as process) could be understood as part of the Mendelian background process rather than as an evolutionary force.

    Reasons For

    1 perspective
    Reason for
    ?
    • 1.The Mendelian process — wherein organisms produce gametes and gametes produce organisms — is treated as background against which evolutionary forces are described, not as a force itself.
      ?

      Think about whether this reason is strong or weak

    • 2.At least some types of random sampling occur during gamete formation, which is part of the Mendelian process.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    2 perspectives
    Reason against 1 of 2
    ?
    • 1.Random sampling during reproduction produces allele frequency changes that are causally distinct from Mendelian transmission ratios themselves.
      ?

      Think about whether this reason is strong or weak

    • 2.A process that systematically alters population-level outcomes beyond what Mendelian ratios predict cannot be merely background to those ratios.
      ?

      Think about whether this reason is strong or weak

    • 3.Matthen and Ariew's causal decomposition shows drift and selection are individuated by their population-level statistical signatures, not their mechanistic substrate.
      ?

      Think about whether this reason is strong or weak

    Reason against 2 of 2
    ?
    • 1.The background/foreground distinction in causal explanation is context-relative and pragmatic, not ontologically fixed.
      ?

      Think about whether this reason is strong or weak

    • 2.Designating Mendelian processes as background arbitrarily privileges one causal level, as Millstein's population-level causal account of drift demonstrates.
      ?

      Think about whether this reason is strong or weak

    • 3.If sampling error during gamete formation causally explains outcome variance, reclassifying it as background eliminates rather than resolves its explanatory role.
      ?

      Think about whether this reason is strong or weak

    What, then, are the statisticalist issues that random drift is entangled with? The concerns raised by Walsh, Lewens, and Ariew (2002) and Matthen and Ariew (2002) have their origins in claims made by Sober (1984) in his classic The Nature of Selection. Sober characterizes evolutionary theory as a theory of forces, with its zero-force state described by the Hardy-Weinberg equation of population genetics (see the population genetics entry for an explanation of the equation); in such a state, the
