    HistoryEditSee Inverse

    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

    1 perspective
    Reason for
    ?
    • 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

    Reasons Against

    2 perspectives
    Reason against 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 against 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

    To be clear, however, there can be indiscriminate sampling processes and discriminate sampling processes occurring in the same population, even with respect to the same trait. For example, in a study of over 900 populations, biologist Maxime Lamotte acknowledged that camouflage gave appropriately colored Cepaea nemoralis land snails a selective advantage in their respective environment while simultaneously maintaining that foundings of new populations are “of considerable importance because of t
