Cloning Essay example

We should clone endangered and extinct animals because they can help cure diseases that we don’t know how to do today or that we don't have the ability to do today. It is a good idea to clone animals because

Animal cloning started without the world even knowing. First, an animal clone is “an exact physical copy of one ‘parent’” (Newman 12). “Animal cloning experiments began in the 1960’s. Frogs were the first subjects. By 1987 scientists had begun cloning cows and other mammals” (Newman 12). Dolly the sheep was the first big cloning success, credited to Ian Wilmut in 1996 (Praded 21). This sheep was a scientific breakthrough, but it also caused many people to question the intents of scientists. Many people wondered if scientists would clone humans next. The original intent of animal cloning was not for the food industry. The reason animal cloning started was to find a way to help cure currently untreatable diseases (“Why Do Scientists Clone?”). By cloning cells, scientists will be able to manipulate the cells to become something new.

Scientists in 2009 attempted to clone an extinct species of wild goat, the Pyrenean Ibex, otherwise known as the bucardo. After many attempts, one surrogate goat mother became pregnant and gave birth. Unfortunately, the babe died in just moments after birth. However this cloning took place only seven years after the cloning of dolly the sheep in 2002, the first successfully cloned mammal. Making the jump from cloning being impossible to nearly reviving a dead species just seven years later shows proof how quickly this incredible technology is advances. It has now been over a decade since the cloning of the bucardo, and the technology available now would very likely produce a healthy clone. The only question now is, should we? Some in favor of de-extinction argue for the possible medical benefits that could be learned by furthering research in this field. Most pharmaceutical drugs are not made from scratch, but instead derived from natural compounds found in wild plants, or animals. Innumerable species have gone extinct before science even had to opportunity to attempt to research them. Bringing species back gives us the unique opportunity to study these species of plants and animals to learn from

For the longest time, in our history and modern times, people have thought of animals as friends and even sometimes sacred beings. Cloning would allow you to keep your friend back from the dead as a new being. The article states that certain labs are using cloning to help bring back endangered species, as well. This is important because there are many animal species that are endangered, soon

Animal cloning is a problem that many of us unknowingly approve of every day. Hundreds of innocent animals are dying and suffering due to animal cloning experiments.

For many years, animals have been used to facilitate the testing of new procedures, drugs, and quest for information. Now as we enter the 21st century, humanity has created computer prediction models, tissue cloning, and great understanding of chemical reactions. However most of these new methods still are only sparingly used, despite their accuracy, and animal testing still remains the test method of choice. There's a newly developed technology that can allow doctors and scientists to duplicate living organisms. This development in technology is known as cloning, and it has forever changed the views of life. Cloning can serve as the answer to problems which plaque the human, animal, and plant populations. Any living species can now be

Why we choose to do cloning on endangered animals such as the Eastern Lowland Gorilla.

With cloning the risk to animal welfare is significant. Cloned animals often die in a painful manner. Cloning is not efficient and many animals are needed, in fact, less than 5% of potential clones develop into live offspring (Shapiro). Considering that cloning itself is extremely controversial, mix it with the revival of extinct species and many believe that we are playing god. In fact, Stuart Brand famously said, “We are as gods and might as well get good at

Scientific experimentation has led us to many great discoveries such as: Chemotherapy, heart surgery, and bone marrow transplants. Recently scientists have discovered a new way to heal humans. This is known as cloning. Although they have yet to clone a human they have cloned sheep. Cloning has brought up a huge controversy among the American people. There are two sides to the story. Either you agree with cloning or you don’t. The only way to help make that decision is to look at the good and bad points of cloning.

Cloning has many shortcomings. First, the organisms have a shorter life span and are more susceptible to contracting one to several diseases. These diseases can lead to a lower quality of life for the organism. Also, cloned offspring are very likely to contract "Large Offspring Syndrome”, which is a syndrome in which the offspring is significantly larger than the normal breed (Rantala, 103). Cloning is not natural, it is costly, and it is a

No one knows why these attempts failed and why one succeeded.” (Kolehmainen, 2017) To see something as valuable as an embryo carelessly destroyed in the process of reproductive cloning is a travesty, in numerous ways, not only does it further prove that cloning unable to safely provided a stable live product, but more so destroys a multitude of potential lives to create one possible abominate one. In accordance to Dr. Tanja Dominko’s reports, in the New York Time article “In cloning, Failure far exceeds success”, her three years of experimenting, and going through 300 attempts with monkeys, the only result she has come up with are some of the most grotesquely abnormal embryos containing cells that have little to none chromosomes whatsoever. Some even bare resemblance to that of cancerous cells as opposed to animals with healthy cells. (Kolata, 2001) But, the most promenade one, which has been over looked the most by far, would be the indefinite hazardous consequences cloning would have on our gene pools. “The process of cloning would inevitably invite the use of other genetic technologies, specifically genetic manipulation of cloned embryos, and this could result in permanent, heritable changes to the human gene pool.” (Kolehmainen, 2017) Such practices of artificially creating a human being only spills disaster in the laboratory, in more ways than one. Materials and funds go to waste with each failure, and those clones that do indeed exist do not last

Since 1938, cloning has been a topic some scientists have experimented with. Hans Spermenn had a "fantastic experiment" which was to replace the nucleus of an egg with the nucleus of another cell and to grow an embryo from such an egg. In 1952, Robert Briggs and Thomas King was unsuccessful in the attempt to clone a Rana pipiens frog. in 1970, this time John B Gurdon was successful in his attempt to clone a Xenous laevis frog, although it only reached the tadpole stage. Karl Illmenese and Peter Hope clone a mouse in 1981, in 1994 the first sheep was attempted to be cloned by Neal First. By 1995 two sheep were cloned by Ian Wilmut and Keith Campbell, they brought us the first real animal clone Dolly the sheep in 1996. After Dolly there were many animals cloned, 1998 was a mouse, 2000 a monkey and a pig, 2001 was a buffalo and a cow, a cat was cloned that year. In 2002, was mice and in 2003 there were many clones in animals, a rabbit, mule, a deer, horse and a rat. 2004 brought us fruit flies, and a group of Korean scientists were allegedly announcing they cloned human embryos although it was determined to be false information. in 2005 an Afghan hound, 2007 a wolf, 2008 a Labrador dog, 2009 was when an animal from an extinct species was cloned the Pyrenean Ibex, which lived for 7 minutes. Also in 2009, a female camel was cloned.

In 1997, the first primate was created by embryonic cell nuclear transfer. The scientist Li Meng, John Ely, Richard Stouffer, and Don Wolf, fused an early stage embryonic cell with an enucleated monkey egg cells using electrical shock. The embryos were then implanted into a surrogate. Out of 29 cloned embryos, two monkeys were born. The female was named Neti and the male was named Ditto (“The History of Cloning” par. 25-26). This experiment showed that primates, which are the closest relatives to humans, can be cloned. Which gives scientist a good model to continue to research cloning, to find more cures for disorders and diseases. In 2001 Pasqualino Loi of the University of Teramo in Italy and his colleagues, recovered cells from the ovaries of two female mouflons and injected their nuclei into a sheep egg cells that had their nuclei removed. This resulted into a baby mouflon (“The History of Cloning” par. 30-31). This allows scientist to continue to explore cloning as a way to create animals belonging to endangered or extinct species. In 2009, using goats as egg donors and surrogates a team of scientist led by Alberto Fernandez, cloned the first extinct animal, a Spanish mountain goat called the Bucardo (“The History of Cloning” par. 30-31). Even though the survived gestation died soon after birth, this achievement showed to scientist that it is possible to cloned extinct species and it could work for another species.

Cloning has been a mystery that has puzzled the majority of scientists through many decades on how they could be able to achieve the impossible, many have given up and thought of this action as an impossible accomplishment that may never become a reality of the world. Over the past recents decade this impossible accomplishment is now becoming a reality to the world. “A clone is a genetically identical copy of an organism, and it may be created asexually oe created in a lab. The three types of cloning consist of reproductive, gene, and therapeutic cloning” (“Cloning”). There have been many attempts throughout the years of trying to produce a cloning until finally in 1979 the first reproductive animal clone was developed a sheep named polly who was the clone of her surrogate mother dolly the sheep. Therapeutic, reproductive, and animal cloning should be implemented more in the United States of America; because it will increase medical advancements in organ transplants, will give infertile parents a chance to procreate, and will give scientists the chance to further cloning and acknowledgments of diseases.

Most of us are ignorant on what’s happening around us, we are so focused on technology that we are not aware how our environment changed, besides the fact of it getting destroyed because of the irresponsibility of men. Animal Cloning is a sensitive topic because the way we live is at stake, our health is at stake. This topic will enlighten us on how cloning can help us in terms of food production and animal conservation. Studying cloning can give us ideas on how some movies came up with cloning concept. Some thinks that animal cloning is necessary for us, but not human cloning, that is beyond immoral. Advances in animal cloning has been made, scientists are planning to do more. Animal cloning can help preserve the endangered species by cross breeding. Some things can and cannot be done. It can be said that cloning is still in its developmental stage, with the continuous study and research, efficiency and effectiveness in cloning can be created for best result. Cloning needs to have an ongoing assessment and modeling of the technology where its is best suited. Some will not be realized until in the future.
