    Reasons For

    1 perspective
    Reason for
    ?
    • 1.In a study of over 900 populations, camouflage gave appropriately colored Cepaea nemoralis land snails a selective advantage (discriminate sampling)
      ?

      Think about whether this reason is strong or weak

    • 2.Lamotte simultaneously maintained that foundings of new populations are of considerable importance because of chance variations in the composition of the first colonizers (indiscriminate sampling)
      ?

      Think about whether this reason is strong or weak

    • 3.Both processes were observed operating on the same trait — shell color — in the same populations
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    2 perspectives
    Reason against 1 of 2
    ?
    • 1.A process is discriminate or indiscriminate relative to a description of the mechanism, not relative to the trait affected.
      ?

      Think about whether this reason is strong or weak

    • 2.If colonization founding events causally track shell color frequencies (however imperfectly), the process is discriminate, not simultaneously both.
      ?

      Think about whether this reason is strong or weak

    • 3.Lamotte's claim conflates two temporally sequential processes acting on the same trait with two simultaneous causal processes, which is a category error.
      ?

      Think about whether this reason is strong or weak

    Reason against 2 of 2
    ?
    • 1.Matthen and Ariew argue that drift and selection are not distinct population-level causes but are statistical abstractions over individual causal histories.
      ?

      Think about whether this reason is strong or weak

    • 2.If drift and selection are not ontologically distinct causal processes, the claim that they 'simultaneously occur' misrepresents a single causal process under two mathematical descriptions.
      ?

      Think about whether this reason is strong or weak

    • 3.The Cepaea case therefore shows one causal process—differential survival by color—being decomposed statistically, not two processes genuinely co-occurring.
      ?

      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
