"What do all the ages of the individual lifetime continuum share?... The very proteins that organ transplanting tries to deal with and leads some scientists to want a blanket approval for therapeutic cloning. But I suspect you knew that."

And at what stage does the protein production become differentiated enough to be able to deam it an "individual" ?


But I suspect you know that and really don't want to use that as a starting point.

Your question doesn't make sense. The zygote is an idividual. It produces human proteins in an organized manner in such a manner to maintain homeostasis and growth in the form of cell division then *cell* differentiation.
I think you may be mixing up the concepts of "potential" (dependent on environment) and "what it is" (genetics). The Bioethics Council link also discusses this: there is no difference between the cloned human embryo that is implanted in the uterus and the one that is harvested, just as there is no difference between the embryo that is wanted and the one that is not.
