Cloning began by curiosity and built itself into a geneticist's way to replicate various genetic materials such as gene segments and cells. When it was discovered that the cells could be reproduced, it eventually led them to think that just maybe a whole organism could be cloned. They worked up to larger and larger organisms and finally Dolly arrived. She was made through a cloning process that generally takes a fair amount of time. It all starts when the scientists transfer the nuclei from the various types of sheep cells into unfertilised sheep eggs from which the natural nuclei had been removed by surgery. Once the transfer is complete, the recipient eggs contain a complete set of genes, just as if sperm would have fertilized them. The eggs are then cultured for a period of time before implanting them into the sheep that will carry them to term. The resulting lamb was an exact genetic copy of the sheep that provided the transferred nucleus, not of those who provided the egg.
One reason people are so against cloning is the fact that it could produce abnormalities. This could be the main reason that science is holding out on cloning humans. Other arguments are that cloning is against religious beliefs, being unnatural. Some wonder how the clone would feel emotionally if they found out that they were cloned or if they'd have problems. Many people also wonder who would be cloned. If clones were nurtured and used as organ banks, this would change the nature of what it is to be human because it is taking the aspect that a human life is not worth much. And what if a clone was allowed to develop as a normal child who would be responsible for her welfare, who would be her parents, how would she cope psychologically and socially? Because of such unanswered questions, many scientists say that human cloning should be postponed until issues are resolved. Nonetheless, some people wanted attempts at human cloning to begin as soon as possible. They include a Chicago scientist who announced his intention to open a group of clinics to clone humans.
Although many people think it is wrong, they are still curious to find out if cloning humans is really possible. Cloning might have its advantages and could help people or make them livelonger. Scientists say that cloning a human embryo would make research into genetics and genetically related diseases easier and cheaper. Others say that it could even solve some problems with infertility since replacement of the ova in in-vitro fertilization is sometimes painful, traumatic, and often unsuccessful. Another benefit would be that the cloning of animals might make food be of better quality, yet less expensive. For example, a clone of a cow might eventually be sold in the meat market. This would change the industry of the sales of meat to make "genetically superior animals" for food consuming (Chadwick). The most recent experimenting is on producing human proteins in animal milk. Scientists hope that two cows from Texas, George and Charlie, will be the first cows that will produce milk that will have drugs for the use of humans. Though many of us think that cloning is recent, it has been around for a bit longer than we think.
In conclusion human cloning has many advantages, but has too many moral dilemmas for it to be developed into a mainstream scientific practice. These issues need to be addressed, but in this modern society, it is likely that cloning will soon be a large part of society with-in 10 years. Human cloning can provide cures for cancer, diabetes and heart disease. Protein-enriched milk form cloning cows will be a great vehicle of vaccines to children, cloning could improve life expectancies and living standards around the world, but until welfare of clones are guaranteed and nearly all possible abnormalities and dangers are solved, cloning should not be introduced in our society.
