I suppose you could get the same results if you bred a special group of humans who were "identical". Maybe that's what the woman is up to in California wth the 8 babies.
I once was a member of a merry band of libertarians and Ayn Rand objectivists who educated me quite a bit re: economics. But when it came to social issues, what they had to say literally took my breath away. The more extreme end of this merry bunch of libertines actually looked forward to the day when brainless human bodies could be grown on vast farms for organ harvesting. Needless to say, the welcome mat was quickly withdrawn once I started speaking my mind on the subject.
