I am more interested in the "science" of this debate than the ethics and legality of abortion.
Legal personhood wasn't being argued. Whether or not the living, growing "thing" is a human is.
Our bodies are full of life that isn't exactly our own and can be distinguished from us by analyzing the genetic code. An appendix would share the same genetic code as its host, correct? Couldn't a simple DNA test of the fetus determine if it is indeed a separate organism or if it simply an appendix, fingernail, or tumor of the host?
Sure, normally humans breathe air, have two arms and two legs (featherless bipeds, if you will). But, there are exceptions. People may have more or less arms and legs, and there is the possibility of liquid breathing of oxygen rich fluids. Is a human suddenly not a human when breathing in this manner?
