Two precious human beings are involved in an abortion, the mother and the unborn. The unborn at all stages of development is completely human. From the very moment of fertilization they have their own distinct DNA. They will always be human beings that never existed before until the day they die. None of that ever changes regardless of size, shape or where they live. The unborn's little body is distinct from his or her mom's. Each is an entirely different human being. Two hearts are beating. Each has a different brain and central nervous system, and may have a completely different blood type, skin color and gender. The little one may be doing something totally different than the mother - sucking their thumb or hiccupping even while mom is sleeping. Abortion clearly involves two living persons. Only living things grow.
