    It is not the case that The argument that human beings come into existence at conception is undermined by the twinning case.

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

    Reasons For

    1 perspective
    Reason for
    ?
    • 1.Twinning is a real-life instance of the argument from fission.
      ?

      Think about whether this reason is strong or weak

    • 2.In twinning, the original embryo (Adam) cannot survive as both twins, as only one twin, or at all.
      ?

      Think about whether this reason is strong or weak

    • 3.If Adam does not survive, new human beings come into existence at twinning, not at conception.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    2 perspectives
    Reason against 1 of 2
    ?
    • 1.Twinning produces a new individual by division, but the original embryo persists as one of the resulting twins, just as an amoeba persists through fission.
      ?

      Think about whether this reason is strong or weak

    • 2.Eric Olson's animalist framework holds that biological continuity, not numerical identity across branching, determines which organism persists.
      ?

      Think about whether this reason is strong or weak

    • 3.The twin who inherits the majority of the original embryo's cellular matter retains the original organism's identity, grounding conception-based personhood.
      ?

      Think about whether this reason is strong or weak

    Reason against 2 of 2
    ?
    • 1.Patrick Lee and Robert George argue that twinning shows developmental plasticity, not the absence of a determinate individual prior to the split.
      ?

      Think about whether this reason is strong or weak

    • 2.A human organism can be a fully determinate individual from conception even if it later undergoes division, just as a nation remains real before it partitions.
      ?

      Think about whether this reason is strong or weak
