    It is not the case that Founders of a new population can constitute an indiscriminate sample of the whole original population even if they all originate from the geographic edge of that population

    Reasons For

    2 perspectives
    Reason for 1 of 2
    ?
    • 1.Geographic edge populations systematically exhibit reduced genetic diversity due to serial founder effects and range expansion dynamics.
      ?

      Think about whether this reason is strong or weak

    • 2.If edge populations are already genetically impoverished relative to the core, founders drawn from them are statistically biased samples of heritable variation.
      ?

      Think about whether this reason is strong or weak

    • 3.A sampling process that systematically under-represents heritable variation from the core population is discriminate with respect to those heritable traits, regardless of whether geography itself is heritable.
      ?

      Think about whether this reason is strong or weak

    Reason for 2 of 2
    ?
    • 1.Matthen and Ariew argue that population-level statistical outcomes cannot be decomposed into individual-level causal processes without remainder.
      ?

      Think about whether this reason is strong or weak

    • 2.If the causal history of which individuals become founders is partly constituted by geographic structure, then geographic origin is causally integrated with heritable trait transmission, not separable from it.
      ?

      Think about whether this reason is strong or weak

    • 3.The Causal Process Account's clean distinction between heritable and non-heritable variation presupposes a modularity of causal factors that actual population genetics does not support.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    1 perspective
    Reason against
    ?
    • 1.The geographic location of founders is a non-heritable variation
      ?

      Think about whether this reason is strong or weak

    • 2.The Causal Process Account evaluates indiscriminate vs. discriminate sampling only with respect to heritable variations
      ?

      Think about whether this reason is strong or weak

    • 3.Origin from a geographic edge does not entail that founders were sampled in a discriminate manner with respect to heritable traits
      ?

      Think about whether this reason is strong or weak
