There's only one: a clone will have genetic material that is identical to the genetic material of someone who already exists, while a "regular" IVF child will have a combination of two sets of currently existing genomes.
you mean like a twin? i don't get what the big deal is about this whole thing. twins have identical genetic information and none of them lack a soul or recognition of personhood (except those olsens, and they're not identical anyways).
Harvesting organs is indeed one of the goals of cloning. Something similar is already happening with the so called "designer babies" that some parents have conceived in an attempt to use umbilical cord cells or bone marrow cells (?) to save an older brother or sister with a serious dissease. Once more cloning will just be an extension to this. Once more it will not have much effect on how we regard the clones as full human beings or not.
As to having clones available as a reservoir for organs that are absolutely essential for survival (unlike kidneys where you can miss one), the goal here will be to farm them as bodies without nervous system and brains. Those will be human in the same sense as individual organs are human, but they certainly won't have personhood. Again conservative forces will have more trouble with this, but again their resistance will subside once all the advantages will become clear and actual.
i was under the understanding that they were intending to try to grow organs without growing whole "people" with or without nervous systems.
Are you referring to the rather naive and/or nutcase supporters of cloning.
i think he's referring to the idea that anything short of massive numbers of natural babies from people who won't even look at birth control pills and permanent life support for brain dead people is evil and does not glorify god. having babies with fatal diseases or significant, life-threatening defects is irresponsible. having babies you can't feed or care for is irresponsible. preventing research that could save lives --when the research is done with consideration to ethics and *some* idea of the sanctity of life-- is irresponsible. having multiple babies in a starving and overstretched world is irresponsible.
...but then so may be allowing science to save lives that nature would destroy.
need i mention that i *love* when fundamentalists reference malthus in the negative. it makes me giggle.
