Has a human been cloned but not been released to the world?
jacquesm: There are enough unethical scientists out there that it is a distinct possibility, the problems that still need to be overcome according to literature are 'doable'.That said, I would also bank on the ego of those scientists to attract attention to the fact that they 'did it' as soon as such as human was carried to term.So, on balance, can it be done ? Yes, probably. Has it been done ? Probably not.The age of the individual would not really factor in to the equation at all imo.
