The no doubt significant accomplishment of Ian Wilmut and Keith Campbell was, that they managed to 'bully' through starvation an egg of sheep A into accepting the cell of an udder of sheep B in lieu of a sperm. The resulting zygote was then implanted into the uterus of sheep C and brought to term in the usual manner of natural propagation. The accomplishment of these Scottish scientists lay in the acceptance of the udder cell in lieu of sperm and complete dominance of the DNA of the egg, which was presumably due to the inability of a somatic cell to assert its own DNA. With all due respect to Wilmut and Campbell, the above seems to relate to the cloning of my endocrine system, like climbing a step ladder relates to reaching the moon. The Scotts have merely found a variation to the natural reproductive process, which allowed one DNA absolute dominance. But back to my concerns, that while I agree, that the primary 'seat' of the essence of my personality is located in my brain, a significant part of it is, what I call my soul, my hormone system. I am not quite sure how that, even giving cloning, can be integrated into an artificial construct. It is reasonable to assume, that if we can selectively clone an endocrine system, without cloning the rest of the individual with it, we may not be far from cloning all but the cranial part of the CNS. So where does the artificial construct come in, that many of us anticipate uploading to? Olaf Henny ******************************************************** - I used to be the nicest kid.
