Cloning Humans Essay, Research Paper


?And the Lord God formed man of the dust of the ground, and breathed into his


nostrilsthe breath of life; and man became a livingsoul . . . and He took one of


his ribs, and closed up the flesh instead thereof; and the rib, which the Lord


God had taken from man, made He a woman and brought her unto man.? -Genesis


2:7 21-22 Human cloning is becoming one of the most controversial topics of our


time. With recent technological breakthroughs, whole new fields are opening with


amazing possibilities. Despite the great advantages that cloning can offer


humanity, there are just as many negative aspects of the technology, which have


given way to large anti-cloning groups who are gaining ground as to the future


of this awesome power. In truth, cloning could very well be the best, or worst


thing ever to happen to mankind. The possibilities of human cloning are vast


indeed, but research in the area has been dramatically restricted in the United


States and in some other countries. Pro-life groups that oppose free access to


abortion have considerable political power, and were able to have all human


embryo research banned by the Reagan and Bush administrations in most of the


1980?s and the 1990?s (religoustolerance). Although the ban was lifted


during the first days of Bill Clinton?s presidency, in 1997 he sent a bill to


congress marked ?immediate consideration and prompt enactment? stating that


it would be illegal to create a human clone whether in private or public


laboratories. Along with the US ban, nineteen European countries including


Denmark, Estonia, Finland, France, Greece, Iceland, Italy, Latvia, Luxembourg,


Moldova, Sweden, Macedonia, and Turkey, signed a protocol that would commit


their countries to ban by law any intervention seeking to create human beings


genetically identical to another human being, whether living or dead. It rules


out any exception to the ban, even in the case of a completely sterile couple.


Britain and Germany however, did not sign this agreement. Germany claims that


the protocol would be weaker than the anti-research laws they already have,


while Britain strongly supports their decision to enforce freedom. French


president Jaques Chirac stated that ?Nothing will be resolved by banning


certain practices in one country if scientists and doctors can simply work them


elsewhere.? Despite all these obstacles, Dr. Richard Seed, a strong supporter


of human cloning, caused uproar when he announced his plans to set up a clinic


to clone human babies for infertile couples (CNN). We may not know the


individual or team who first performed cloning of human embryos, but the methods


used have been understood for many years and actually used to clone embryos of


cattle and sheep. It is likely this has already been successfully used on human


embryos in secret. Robert J. Stillman and his team at the George Washington


Medical Center in Washington D.C. took 17 flawed human embryos, which had been


derived from an ovum that had been fertilized by two sets of sperm resulting in


an extra set of chromosomes, and dooming the ovum’s future. The cells would have


eventually died no matter how they were treated. Stillman?s experiment showed


that the best results could be obtained by interrupting the zygote at the


two-cell stage, separating the cells, and placing them in separate dishes as to


allow them to begin growing again. Many of these pairs were able to develop to


the 32-cell stage, but no further. They might have had the potential to develop


further and even mature into a viable fetus, except the original ovum was


defective and would have died anyway. For ethical reasons, the researchers


selected embryos that had no possibility of ever maturing. The main motive of


the experiment seems to have been to trigger public debate on the ethics of


human cloning (religioustolerance). Dr. Steven Muller headed a panel in the US


whose mandate was to produce preliminary cloning guidelines. These would be used


by the federal National Institute of Health to decide which cloning research to


fund. The panel recommended that studies be limited to the use of embryos that


developed during in vitro fertilization procedures that had been

performed to


assist couples in conceiving. Often, extra zygotes are produced that are either


discarded or frozen for possible future use. They further recommended that any


studies be terminated within fourteen days of conception. At that gestational


age, neural cord closure begins; this is the start the development of nervous


system. The scientific community had deemed the actual act of cloning a mammal


impossible, until Dr. Ian Wilmut of the Roslin Institute in Roslin, Scotland


achieved it in July of 1996. The success of his experiment was communicated to


the press on February 23rd 1997. "Dolly", a seven month-old sheep, was


displayed to the media; she was the first large cloned animal using DNA from


another adult. Since Dolly’s conception, the Institute has successfully cloned


seven sheep of three breeds. The technique that they developed can probably be


applied to other domesticated mammals. On December 14 1998, researchers at the


infertility clinic at Kyeonghee University in Korea announced that they had


successfully cloned a human. Scientists Kim Seung-bo and Lee Bo-yeon took an


ovum from a woman, removed its DNA and inserted a somatic cell from the same 30


year old woman into the ovum. Their reports stated: " We were able to


confirm division up to the fourth cell stage, the stage of embryo development


when a test tube embryo is usually placed back in the uterus, where it then


further develops into a fetus." The goal of their research was not to clone


a human, but to clone specific, genetically identical organs for human


transplant. They did not implant the clone into a human uterus because of


ethical considerations. They destroyed it. The Korean Federation for the


Environmental Movement immediately issued a statement criticizing the study.


Members of the Life Safety Ethics Association held protest demonstrations in


front of the University (religioustolerance). Despite popular belief, cloning


has been used since the early 1950?s by farmers to ensure good crops using a


technique in which the nucleus of an egg cell is destroyed, and replace it with


a nucleus from the cell of a higher organism. The egg will then grow into a


genetic copy of the donor organism. While this process can ensure crops


identical to a previous harvest, It will not work on mammals, because of the


tiny size of the eggs (Clone). Possibilities for cloning include such things as


creating children for infertile couples, harvesting genetic copies of organs to


avoid rejection by the immune system in transplants, or even going as far as to


create replacement children for parents who have lost someone in some sort of


accident. Cloning may even hold the key to a cure cancer. The materials to


create a laboratory can easily be purchased in most major countries at a fairly


cheap price. A working cloning facility could be built in a garage with as


little as $10000. In reality there is no way to prevent the cloning of a human


being. It would be better for someone, who is responsible enough to use the


technology intelligently, than for someone to use the secret of cloning to there


own advantage (Kaku). All in all, human cloning could possibly be the most


significant event in human history. Should we take one road to a


totalitarianistic society of genetically engineered clones like Aldous


Huxley?s Brave New World, or a world in which parents can create designer


children with the characteristics of their choice as in the movie ?Gattaca??


The incredible power held within our genes could possibly lead to a perfect


society where peace and happiness reign supreme, or it could very well lead to


the destruction of the human race itself.
