There can be no such recognition in the case of a fertilized egg. A fertilized egg has no recognizable human features even under a microscope, has no neurons and feels no pain. When it dies it does not suffer.

Agree. And the same for the implanted embryo, up to a point. Picking a point later for legal protection gets harder.

However, killing the living embryo does end an individual human lifetime ... every time.
