    Natural selection can increase the proportion of organisms with characteristic C in a population without C itself being genetically encoded.

    Reasons For

    1 perspective
    Reason for
    ?
    • 1.Organism O has a genetically encoded disposition N to build a special kind of nest.
      ?

      Think about whether this reason is strong or weak

    • 2.Being raised in this kind of nest causes O-type offspring to develop characteristic C.
      ?

      Think about whether this reason is strong or weak

    • 3.Os with characteristic C enjoy greater reproductive success than those without C.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    2 perspectives
    Reason against 1 of 2
    ?
    • 1.Natural selection requires that the selected-for trait itself be heritable, not merely a downstream effect of a heritable disposition.
      ?

      Think about whether this reason is strong or weak

    • 2.If C is causally produced by the nest rather than encoded in the genome, C's heritability is environmental and breaks the genotype-phenotype link selection requires.
      ?

      Think about whether this reason is strong or weak

    • 3.Without direct heritability of C, selection increases N but cannot be said to select *for* C, making the claim equivocate on what selection targets.
      ?

      Think about whether this reason is strong or weak

    Reason against 2 of 2
    ?
    • 1.Sterelny and Griffiths's 'causal parity' thesis entails that privileging genetic encoding over developmental environment misidentifies what carries evolutionary information.
      ?

      Think about whether this reason is strong or weak

    • 2.However, parity cuts both ways: if environmental and genetic causes are symmetric, then C's frequency increase is attributable to habitat selection, not natural selection proper.
      ?

      Think about whether this reason is strong or weak

    • 3.Therefore the scenario redescribes niche construction or cultural inheritance, which are distinct evolutionary processes from natural selection acting on genetic variation.

    To see this, suppose that an organism O has a genetically encoded disposition N to build a special kind of nest; suppose further that being raised in this kind of nest causes O-type offspring to have characteristic C; and suppose finally, that Os with C enjoy greater reproductive success than those without. Then, assuming that there is variation in N in the population, natural selection can operate so as to increase the proportion of Os with N — and hence also those with characteristic C —
