Really? This would require the [group of cells] to be something other
than human life between the meeting of the sperm and the egg, and the
beginning of human life. During this time the [group of cells] would have
to be either: a) not human or b) not alive or c) both.
It is well known that a significant fraction (1/3?) of fertilized eggs never make it to a live birth.
More like 1/2, I think. But I don't have a reference to cite on that.
I know of someone who had had more than one baby the first time around and was having an early ultrasound after she'd discovered she was pregnant a second time. The first ultrasound revealed 2 fetuses, but only 1 heartbeat was detected. The second ultrasound a couple of weeks later revealed only 1 fetus. (There is speculation that the "vanishing twin" syndrome is more common than we think, but I'm not sure how common it supposedly is.)
