Dolly the sheep was the first cloned animal and what interested the world of cloning. There was a sudden curiosity that rose in society about how cloning benefits the common man. If they could do it to a sheep, why not anything else? When the media is talking about cloning, it is usually talking about reproductive cloning. There are different types of cloning however, and cloning technologies can be used for other purposes besides producing the genetic twin of another organism.
The reason cloning became an interest is because if the vital organs of the human body can be cloned, they can serve as backup systems for human beings. Cloning can also be a solution to infertility, cloning has an option for producing children. Cloning may make it possible to reproduce a certain trait in human beings. We will be able to produce people with certain qualities, human beings with particular desirable traits, thus making human beings a man made being. Genetic researchers may be able to understand the composition of genetic constituents on human beings better. Cloning can serve as the best means to replicate animals that can be used for research purposes. If positive changes can be brought about in living beings with the help of cloning, it will indeed be a boon to mankind.
Cloning created identical genes, which is a process of replicating a genetic constitution therefore it hampers the differences in genes. If we lessen the diversity in genes there is less of a chance for adaptation. Cloning can offer the ability to choose which traits fir reproduction it also has the chance of giving undesirable traits. While cloning human organs and using them for ‘spare parts’ or in cloning itself technical and economical barriers will be considered. On the moral and ethical front as well, cloning raises several serious questions. It devalues man-kind, as a new birth is a natural process, and seriously undermines the value of human life. Isn’t it like emulating God? The very being most humans believe there is?
In the end Dolly, the cloned sheep was put down by lethal injection due to lung cancer and arthritis. Dolly or any other animal created using nuclear transfer technology is not truly an identical clone of the donor animal. Only the clone's chromosomal or nuclear DNA is the same as the donor. Dolly's success is truly remarkable because it proved that the genetic material from a specialized adult cell, such as an udder cell programmed to express only those genes needed by udder cells, could be reprogrammed to generate an entire new organism. Is cloning possible for human beings? Or would it be an imitation of God?

“Even if the technique is used only in pursuit of biological knowledge and medical treatments, those will come at the very high ethical price of manufacturing human life for the purpose of harvesting it like a corn crop-that is, for the purpose of destroying it”(Smith 6). As a result this would lead to people rebelling against destroying them and to keep them alive until they die a normal life.“Cloning those animals could produce a whole herd of disease-free animals, saving farmers millions of dollars in lost meat”(Sohn 13). This is important because farmers can have As a result of this farmers will be able to have bigger farms and better equipment due to getting more money. Fewer cows would be needed to make milk if scientist could clone cows with the ability to produce 45,000 pounds of milk(Sohn 12). This is important because if they were able to produce a lot of milk from these cows then they can buy better equipment, land, and more companies to sell their products at. As a result of this the comutnities will be able to get more and better dairy products, veggies, and…

On the other hand, there are quite a few cons that potentially outweigh the pros of cloning humans. The first con is that human cloning is unnatural. According to Lombardo, “many feel that interfering with the natural process of pro-creation would lead to other attributes of life being altered” or displaced from society. Many people are opposed to this issue due to their religious beliefs, because they feel man will be replacing the higher being as the creator of creatures on this Earth. In a scientific point of view, using an older cell to create a new organism could possibly cause an “imprinted age [to] be place on the growing embryo”, resulting in faster aging (“Pros and Cons of Human Cloning”). Lastly, because human cloning is a roughly…

There are some positives to cloning but only therapeutic cloning when it is used to replicate cells. Therapeutic cloning produces embryonic stem cells for creating tissues to replace injured or diseased tissues(3). This can be used to cure people not harm them. Artificial cloning can be good for the studies and discoveries that have been made but otherwise the animals that die are not helping anyone.…

Clones could be seen as less than animals compared with non-clones” (Quinonez, blog.udemy.com). When I was reading I read that cloning is good for one good reason, to harvest the animal's organs. This idea is so inhumane, according (toblog.udemy.com) “While the cloning of body organs can be a great asset to extending human life, it could also cause a lot of malpractice. This could lead to a rise in malpractices within society.” First, scientist create these disgusting creatures and steal their organs for the purpose of human's life, that is just…

Over the years, science and technology have expanded to make it possible to create identical creatures. While new cloning technology is a great advancement, it raises a plethora of moral and ethical questions. Cloning may bring about new ways to find cures for babies, according to Philip M.

Evidence: “ With the advancement and expansion of technology science has been able to achieve new wonders. These improvements and discoveries in science have allowed the human race to explore and learn more about the world. One such phenomenon is cloning. Cloning has opened the doors to explore human beings in a way that was once never possible. With cloning the human body, as well as other organisms, will be studied. Cloning and genetic engineering will both come into play to improve scientific knowledge.” (Serendip, 1)Citation: ( Serendip, Cloning right or wrong)Evidence: Many people believe human cloning should be banned prior to human defects, health problems, not proper treatment, and many other things.

The question shakes us all to our very souls. For humans to consider the cloning of one another forces them all to question the very concepts of right and wrong that make them all human. The cloning of any species, whether they be human or non-human, is ethically and morally wrong. Scientists and ethicists alike have debated the implications of human and non-human cloning extensively since 1997 when scientists at the Roslin Institute in Scotland produced Dolly. No direct conclusions have been drawn, but compelling arguments state that cloning of both human and non-human species results in harmful physical and psychological effects on both groups. The following issues dealing with cloning and its ethical and moral implications will be addressed: cloning of human beings would result in severe psychological effects in the cloned child, and that the cloning of non-human species subjects them to unethical or moral treatment for human needs.…

Scientists eventually cloned a sheep after many failed attempts. The sheep was named Dolly and was born on the 277th try. "Reproductive cloning is a very inefficient technique and most cloned animal embryos cannot develop into healthy individuals. For instance, Dolly was the only clone to be born live out of a total of 277 cloned embryos. This very low efficiency, combined with safety concerns, presents a serious obstacle to the application of reproductive cloning ("Cloning Fact Sheet.")." This could prove to be a wasteful as the embryos won't get a chance to develop into anything. Cloning could seem that way but there is no guarantee the embryos will be able to develop to begin with at all. Scientists using stem cell research or actual cloning of humans may be able to find a way to stop the loss of…

The subject of human cloning is a very controversial topic. The cloning of Dolly the sheep in 1997 by scientist Ian Wilmut generated a very unexpected reaction around the world. However these reactions were not all positive. Cloning refers to the development of offspring that are identical to their parents genetically. While it is referred to as an unnatural process, it can occur quite often in nature. Identical twins, for example, are clones. However, human cloning is very new and very complex. In this essay I will examine both sides of the argument into the banning of cloning starting with reasons why cloning should not be banned.…
