It's entirely a misunderstanding of how people are assigning 'life essence' to the zygote. I think there's a mental gap here. I can honestly understand why people would think that a zygote has a soul. I get it. The zygote is alive and on its way of being a human. Twinning, even, is an intuitive concept. The zygote had one soul, and now it has two - due to the twinning event. Why does the soul enter at twinning? I don't know. But it's easy to see that it does.
However, other aspects of the biology then confuse me. If the zygote has a soul and is alive, then that soul only disappears when the zygote (or its organism) dies, right? That makes easy sense to me. If we cryogenically freeze a zygote, it's still alive, with its soul. It is the chimera that confuses me. The twin zygotes merge to become one fetus. Some of the cells are from zygote A and some are from zygote B. Importantly: both zygotes are alive. They never die, they just fuse into one being.
Now, scientific understanding is that there's one person. Spiritual understanding is very confused. There WERE two souls, and neither of them died. So, are there two souls? I don't see any way around it. There must be.
