On February 24, 1997, the whole world was shocked by the news that Scottish scientists had successfully cloned a sheep. Dolly an artificially cloned mammal was born a star. After the shock, that cloning was not only a possibility but a reality, wore off the out cry against human cloning began. Physicians, scientists, politicians and church leaders and many more have been trying to ban the cloning of humans ever since. Is cloning something to be afraid of? I do not believe it is. I believe that cloning will become a tool of science that will, in time, bring many benefits to humankind.
What is Cloning?
The Microsoft Encarta Encyclopedia describes a clone as "an organism by an asexual (nonsexual) reproductive process"(clone 1). This definition means that we already have many clones on the earth today. The Microsoft Encarta Encyclopedia also states that "the organisms known as prokaryotes (the bacteria and cyanobacteria), a number of other simple organisms, such as most protozoan, many other algae, and some yeast’s, also reproduce primarily by cloning, as do certain higher organisms like the dandelion or aspen tree"(clone 1). The Biology Textbook Concepts and Connections describes a clone as "a single organism that is genetically identical to another"(G-5). With this definition we can come to the conclusion that identical twins are also clones. Cloning then is not a new idea but one that has been around since the beginning of time.

- Human cloning is separated into two major categories; reproductive cloning, which uses cloning technology to create a human embryo that will produce an entire human, and therapeutic, which adopt cloning into field of medical practices to find a cure for many diseases (Kass). Reproductive cloning requires a somatic cell, a DNA-less egg, and a surrogate mother; as a result, it creates a new individual with the same genome, or genetic coding. The idea originated in Germany in 1938, but the first successful research was not conducted until 1967 by scientist John Gurdon, who cloned a tadpole with a frog’s somatic cell....

- Human Cloning Human Cloning comes with two dangerous processes, reproductive cloning (the creating of a new organism) and the therapeutic cloning (the creation of a new tissues or “other biological products”) which affects the ethics of human society. Scientists perceive cloning benefits all men and women, while religious leaders stress the idea of cloning to be an unethical process. Although human cloning serves as an aid to the children and parents with conflicts, cloning is completely unacceptable to convey human life as a product.... [tags: Ethical Issues, Cloning]

- ... Stem cells can replace worn out or damaged tissues and is an alternative to organ donation. It is less likely to result in rejection by the recipient because the tissue would be made from the recipients own genetic material. Like stated previously, therapeutic cloning does not involve the creation of a live human being. However, despite the benefits of therapeutic cloning, there are huge controversies surrounding the topic. One argument against therapeutic cloning is that creating stem cells on a large scale would require the use of vast amounts of human eggs.... [tags: reproductive and therapeutic cloning]

- Imagine living in a society where performing a certain process, a perfect genetically identical copy of a biological entity could be produced (Cloning Fact Sheet, 1). This process is called cloning, and essentially it takes from one’s own genetic makeup to produce an exact replica. These exact replicas, known as clones, can benefit our society in many different ways; however, these benefits are not without great controversy and concerns. Proponents of cloning suggest that through cloning, humans can experience a greater quality of life with fewer health concerns including hunger and reproduction.... [tags: Ethics ]

- The Advantages of Cloning People often question whether or not cloning is morally acceptable in our society, and also if it is worth all the money that we spend on research for cloning. It is hard to believe that not to long ago many people believed that joining a sperm and an egg in a test tube was considered to be morally wrong. It is now used by millions of doctors around the world. Cloning is at the beginning stages of being considered morally unacceptable and will soon move to be just like in-vitro fertilization. Soon everyone will understand the benefits of cloning in agriculture, medicine, and social parenthood. It is quite obvious that cloning has many soci...

- In 1996, Scottish scientist Ian Wilmot and his research team was able to successfully clone a lamb named Dolly from an adult sheep. This invention shocked all of the world at the realization that cloning was no longer a fantasy or an element of a Science Fiction movie. Since then, human cloning has become one of the most debated topics in the world. Everyone started to discuss about its advantages or the ethical issues of human cloning. Most of the people were against it and called it an ‘evil’ experiment.... [tags: human cloning, organ transplants]

- According to Richard Dawkins “Cloning may be good and it may be bad. Probably it's a bit of both. The question must not be greeted with reflex hysteria but decided quietly, soberly and on its own merits. We need less emotion and more thought” (Dawkins, 2011). Cloning is a general term used to describe the replication of biological material (Cloning Fact Sheet, 2009). Throughout this paper the reasoning behind why cloning is an acceptable and potentially life changing science will be examined. Along with this we will take a close look at the arguments against cloning and exploring the flaws within the argument.... [tags: Medical Ethics]

- Imagine a future where humans are manufactured, a future where humans are created by science, a future where humans are the new lab specimen. Human cloning is like opening Pandora's Box, unleashing a torrent of potential evils but at the same time bringing a small seed of hope. No matter how many potential medical and scientific benefits could be made possible by human cloning, it is unethical to clone humans. Before the ethics of human cloning can be discussed, the mechanics of cloning must be understood first.... [tags: Genetics]

- Cloning Should Have Limits "Mary had a little lamb, it fleece was slightly gray. It did not have a father, just some borrowed DNA" (Pence xv, par. 1). According to the article ("Cloning Milestones"), Dr. Hans Spemann visualized cloning back, in 1938 (121). Historical events from 1938 to 2005, provides evidence, that cloning is no longer a vision. Cloning is today's reality. The medical evolution related to the technology of cloning has generated ethical, moral and religious debates for decades.... [tags: Cloning DNA Ethics Stem Cell Research]

- What is cloning. "Cloning is the process of making a genetically identical organism through nonsexual means."(www.Howstuffworks.com) It has been used for thousands of years to produce plants. The next stage was to clone animals. Scientists can take unfertilized eggs of some small animals, and clone them, so they develop into full adults. After knowing that people realized how great it would be if we could clone humans. There would be a lot of advantages in cloning humans. Lets say someone will die if they can't get a heart transplant.... [tags: Clones Biology]
