Dependency: Here the pro-choice activist argues that a fetus is not fully human because they are totally dependent on another human being in order to live. But if that’s the criteria, you can ask about people with disabilities or elderly who are dependent upon others to live. Furthermore, newborns and toddlers are considered to be dependent on other human beings to live.

Thus, Dependency not a quality unique to the unborn that disqualifies it from being considered a human being. The Pro-choice bioethicist Peter Singer agrees. Writing in Practical Ethics, “[T]here is no doubt that from the first moments of its existence an embryo conceived from human sperm and eggs is a human being.”
In Christ, Ken.
