So according to most of those against abortion, life begins at conception. If true, how does chimerism fit into that perspective? For that matter, where do identical twins fit?
For those unaware, chimerism is when two fertilized eggs, early in gestation (days or weeks at most), combine to form a single embryo and generally develops into a single fetus, then a single person is born. On even more rare occasion, the single chimeric embryo can divide to become two twins as well.
And of course identical twins would be one fertilized egg splitting into two embryos generally again very early in gestation. I think conjoined twins is when it happens later in gestation and would also be a part of this discussion.
Where exactly does the other life end or begin? How do you determine which life ended when chimerism occurs? Which life began at conception and which life begins with the split when it comes to identical twins? If you believe in souls, when does the soul enter a body or leave a body?
