It's actually not that bad a place to draw a line. Without implantation the blastocyst will not continue development into a fetus.

"It's actually not that bad a place to draw a line. Without implantation the blastocyst will not continue development into a fetus."



Humans can be killed or die naturally at anytime after fertilization or the quickening of a clone (however or if that's ever possible). But, that doesn't change that the beginning is before implantation. A somatic cell or gamete can't become a blastocyst - aren't actual developing and differentiating beings.
