Let me answer this one for you Jaigner.
Blood and breath, Ann. Before implantation the fertilized egg has neither.
It also can't "eat", it can't respond to its environment (meaning that if the environment doesn't respond to it, the fertilized egg will not continue to develop), it can't reproduce itself (one fertilized egg doesn't create another), and it can't adapt to its enviroment.
There are 5 charateristics of living biological organisms. The fertilized egg only meets one of them: it can be considered "highly organized".
But the first two, blood and breath, those are scriptural criteria for life and we've had this discussion before...
However, it takes time for both blood and breath to happen after implantation. Implantation is usually around day 6 and the heart doesn't start beating until day 22 or so. That means that we can remove the implanted embryo before day 22 without it being an abortion? However, it takes until even later for the placenta to begin to work and the baby's heart is beating before this happens. Additionally, even once it implants in the uterus and becomes a fetus, it still can't reproduce, eat or respond to it's environment so I think that this sort of argument doesn't really work for saying it's OK to abort a baby early and it's not killing a life.
