A The history of cloning animals is as fol?lows. Cloning of nonmammals was first ac?complished in 1952. However,cloning of mam?mals proved much more difficult,with the first successful clone being the sheep,Dolly,in 1996. Dolly died a young death,probably due to the use of aged chromosomes (染色体) in her nuclear transfer (核移植) .Other mammal spe?cies followed rapidly,with mice and cows being cloned in 1998,and pigs in 2000. The first cat was cloned in 2001. Rabbits were cloned in 2002 and the first male mammal (a mule) was cloned in 2003. In 2004,a bull was cloned from a previously cloned bull. The first cloned human embryos were not produced until 2001,when a private company Ad?vanced Cell Technology produced 6-cell embryos. Howev?er,the first cloned human blastocyst (胚泡) was not pro?duced until 2004 by a group in Korea.

Cloning is classified as research and reproductive (繁殖的) cloning. When the embryo is not allowed to live,it is considered research cloning. Otherwise,it is classified as reproductive cloning. About ten states have banned repro?ductive cloning with five banning research cloning. Puerto Rico proposed a worldwide ban of reproductive and re?search cloning in 2003 through the UN. However,objec?tions by Great Britain and other countries resulted in the proposal being formally presented until 2004.

From a Christian theistic (有神论的) world view,cloning or deliberately making changes in the human blue?print is playing God. This is something that would not be forgiven. Alternatively,from the opposite humanist world view,human engineering is no more than helping evolu?tion. Our position on this issue,like so many other cultural issues,is dependent upon our belief on a more fundamental world view truth. This can be seen in the conflicting views regarding government funding and support or alternatively restrictions and moratoriums (暂停，中止) .
