>The cells of a human body share its DNA– if a cell does not have the DNA of the body, it is not a cell of that body.
Not to mickey mouse it, but I’m setting the groundwork, here.
A zygote, the single cell result of an egg and sperm joining, has unique DNA. Therefore, it is NOT part of either the mother or father’s body. The DNA of a human egg joining with a human sperm is human. Therefore, even when it is only a single cell, a zygote is human.
This all happens around ten days before the zygote implants in the uterus, by the way. (Or, if birth control pills and/or “emergency birth control pills” have been taken, when the zygote unsuccessfully tries to implant in the hardened walls of the womb. Yes, I know that birth control usually prevents ovulation–usually.)
A zygote is what many folks refer to as a “fertilized egg.” That’s not exactly true, since the “egg” stopped existing when it joined with the sperm– it’s not like a chicken egg, where there is a shell to define the egg, so that example doesn’t work so well. As I mentioned above, the zygote is not part of the mother or father’s body. It is genetically human. It is alive, as it grows. This is all scientifically true, and I frankly have no patience for anyone who wants to argue something that basic without really good evidence. (See also: color of the sky is blue, water is wet, and dogs don’t give birth to lizards.)
Thus, the only debate point is this: is that human a person or not? Are YOU willing to be the one who decides which human counts as a person, and thus has rights, especially the right to live? There have been others in the past century that were willing to take up that burden– Godwin’s Law prevents me from pointing out the most famous example. (If you don’t know Godwin’s Law, you can try Google.)
For those that argue that we should allow the zygote thru fetus to be killed because of rape, incest and/or problems like Down Syndrome, I challenge you to live what you seem to believe: got get a gun and hunt down every member of those groups that you can find, since there’s no moral problem with killing that group of human.
Incidentally, just about all the royalty of Europe comes from incest, and FDR married his cousin Eleanor Roosevelt. Ethel Waters– a singer in the early 1900s– was born because her twelve year old mother was raped, and Madonna’s mother was talked out of aborting Madonna by a priest. (Well, I suppose some would argue the merits on that case.) For that matter, given the statutory rape laws, most of the first borns in the history of the human race would count as the result of rape– if the mother is under 18, it’s legally rape. (Incidentally, that even applies if the father is under 18.) I figure if you’ve read around online you’ve heard about the “health exception” with Beethoven. This site has more examples. /rant
