    It is not the case that The Biological Species Concept (BSC) defines species membership in terms of relational properties, not intrinsic microstructural ones.

    ?Set your confidence on the premises below to see your aggregate.

    Reasons For

    2 perspectives
    Reason for 1 of 2
    ?
    • 1.Phylogenetic species concepts define species membership via intrinsic genealogical history, not reproductive relations.
      ?

      Think about whether this reason is strong or weak

    • 2.Cracraft and others show organisms in asexual lineages belong to species without any interbreeding relation.
      ?

      Think about whether this reason is strong or weak

    • 3.Therefore, interbreeding is neither necessary nor sufficient for species membership, undermining the BSC's relational account.
      ?

      Think about whether this reason is strong or weak

    Reason for 2 of 2
    ?
    • 1.Homeostatic property cluster theorists like Boyd argue species are unified by shared intrinsic causal mechanisms, not relations.
      ?

      Think about whether this reason is strong or weak

    • 2.The HPC account grounds species membership in clustered intrinsic biological properties that causally sustain each other.
      ?

      Think about whether this reason is strong or weak

    • 3.Relational properties like interbreeding are merely symptoms of deeper intrinsic microstructural homeostatic mechanisms.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    1 perspective
    Reason against
    ?
    • According to the BSC, membership of a species depends on relational properties such as membership of a certain population and interbreeding.
      ?

      Think about whether this reason is strong or weak
