    Reasons For

    2 perspectives
    Reason for 1 of 2
    ?
    • 1.Functional role in cellular networks, not tertiary geometry, determines protein identity across organisms with analogous but structurally divergent proteins.
      ?

      Think about whether this reason is strong or weak

    • 2.Convergent evolution produces functionally identical proteins with unrelated folds, showing structure is neither necessary nor sufficient for classificatory individuation.
      ?

      Think about whether this reason is strong or weak

    • 3.Millikan's teleosemantic account grounds natural kind membership in selected-for causal roles, privileging function over physical substrate in biological taxonomy.
      ?

      Think about whether this reason is strong or weak

    Reason for 2 of 2
    ?
    • 1.Homologous proteins sharing ancestry retain classificatory continuity despite radical structural divergence under mutational pressure, undermining structure as the individuating criterion.
      ?

      Think about whether this reason is strong or weak

    • 2.Boyd's homeostatic property cluster theory permits kinds defined by functionally cohesive causal networks where structure is one dispensable cluster member, not the individuating essence.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    1 perspective
    Reason against
    ?
    • 1.Moonlighting proteins perform multiple functions despite a single structure.
      ?

      Think about whether this reason is strong or weak

    • 2.Intrinsically unstructured proteins lack a fixed structure yet are functionally meaningful.
      ?

      Think about whether this reason is strong or weak

    • 3.Enzymes exist with multiple structural variants that perform the same function.
      ?

      Think about whether this reason is strong or weak

    Philosophers have also discussed classification at the interface of biology and chemistry. Goodwin (2011) has argued that structure is fundamental and sufficient for classification of biomolecules, such as proteins. Tobin (2010a) and Slater (2009) appeal to developments in the relationship between protein structure and function in a number of cases such as moonlighting proteins, intrinsically unstructured proteins, and enzymes with multiple structural variants. They claim that the path from stru
