The Pros And Cons Of Animal Cloning

The concept of cloning has been around since the 1800’s, although, in the field of scientists, it has slowly been evolving into a vigorously debated topic, throughout the last 3 decades. Cloning is essentially defined as the process of artificially reproducing genetically identical organisms. Scientists all around the world, through research, are still learning more about the topic, but the fascinating process officially gained awareness as a result of a 1986 experiment conducted by Ian Wilmut, scientist at the Roslin Institute in Scotland. The project was essentially centred around a sheep referred to as “Dolly” that was cloned in a lab using a frozen mammary cell from another adult sheep. At the time, this was a significant milestone in

The possibility of stem cell research exploded with momentum when a certain sheep named Dolly was born. The reason why this was such a breakthrough is because Dolly was the first mammal ever cloned. Although this all began in 1996, the study into stem cell research has been documented since the 1960’s, where Joseph Altman and Gopal Das brought forward new evidence of adult neurogenesis ( the ongoing stem cell activity in the brain). The birth of Dolly brought many breakthroughs for the scientific community but it also created an avalanche of concern because of the ethical implications. With all of the reporting on Dolly, the news media only spoke of one type of cloning and that is reproductive cloning. This may be the most popular

Does the name Dolly sound familiar? Dolly was the first mammal to be cloned. Cloning has opened many doors and opportunities in the agricultural industry. Cloning also has helped in saving many human lives. Several years ago many people opposed using animal organs for transplants, but today it is accepted. Medicinally and agriculturally, cloning can be extremely helpful to the existence of humans. It is the cloning of human beings that raises the questions concerning ethics and morality. Cloning has become a problem for society, and these problems include a decline of genetic diversity, the morality of cloning, and a cause of psychological problems.

Cloning an animal is full of controversy. However, it is an amazing feat for science and technology. This reason gives cloning a positive viewpoint for many people. Though, the act will still probably remain a controversy. Another reason is that cloning is misunderstood. Many people think that it’s something

When Dolly, the first cloned sheep entered in the news, the cloning controversy is becoming more prominent. Not only researchers, the general public became interested in knowing how cloning is done as well as engage in the pros and cons.

Cloning is the production of an organism with genetic material identical to that of another organism. The word cloning comes from the Greek work klon, meanings “twig,” involves the production of genetically identical animals by a process of nuclear transfer. On July 5th, 1996, at the Roslin Institute in Edinburgh, Scotland, a scientific breakthrough occurred when Dolly, a Finn Dorset sheep, was born. (Seidel, 682) “We transfered 29 eggs into a recipient and only one of them became a live lamb. So you can see it’s a very exciting and encouraging result. The efficiencies are poor and there’s a need for a lot more research.”(npr.org) Where it is a controversial subject, the cloning of dolly the sheep affected the world in a positive way and helped advance medical research in finding cures for diseases.

The world of science fiction came to life in 1997, when the first successful attempt at animal cloning occurred. Dolly the sheep became famous worldwide, and sent the scientific community into a tizzy. However, animal cloning is unethical and wrong, due to the failures, side effects, uses of clones, and the possibility of future human cloning. But to understand this topic more clearly, some basic information must be given. First of all, there are many different techniques that have been utilized in scientist’s efforts, but a great majority of them involve altering the adult cell of a donor to enable it to be reprogrammed. According to Pennisi and Vogel, this consists of taking the cell’s nucleus, then

Debates about cloning only initiated after the first cloned mammal from an adult somatic cell in 1996 was officially declared a success. The cloned mammal was a sheep named Dolly, which then appeared to suffer from health conditions that ended her life at a young age (Pano, 36). “This ignited a worldwide controversy about whether or not cloned animals die prematurely” (Lew, chapter 1).

From Star Wars to the Jurassic Park movies cloning has always been a science fiction story that was light years ahead of us. But with recent evidence and research to clone living organisms, the far away fantasies of cloning we have been dreaming about for many years is rapidly becoming a reality, even faster than we think. Twenty years ago, in 1997, Dolly the Sheep was the first successful clone to be produced from an adult mammal. In the article “The Coming of Clones” American Scientists announced in 2013 that they had for the first time successfully obtained stem cells from cloned human embryos (the building blocks of cloning life). Due to this announcement and the cloning of Dolly, cloning has become a debatable topic that has both negative

Even though there is a profound pro that supports cloning, there are just as many cons when it comes to this process. Even though cloning is a powerful tool, it is not entirely safe. Cloning still needs a lot more research before it can become completely safe. It took almost 300 clones to be created before Dolly was produced. The world was shocked but did not understand that she had some imperfections. Dolly grew up very sick and had to be put down because of many illnesses. (17)

Dolly the sheep, was the first animal cloned successfully by scientist, Ian Wilmut at the Roslin Institute in Edinburgh, Scotland. Scientists cloned to mainly see if they could replicate the sheep without inbreeding. Cloning has a great advancement in our society, medical, and scientific researches. It shows that we have many more advancements coming in the future with cloning. Cloning for research should be used for these three main reasons: use of cloning through medicine, cloning to have healthy livestock, and using cloning of animals to see how it affects drug production.

This is not the first time that scientists have used this method to clone animals.. The first animal to ever have been cloned was Dolly the sheep.

Cloning is one of those things that the public probably doesn’t think has been around for that long of a time. It has been around for more than a hundred years, the first recorded experiment ever done was in 1885 by a man called Hans Adolf Edward Dreisch. He split a sea urchin cell in half at an early stage and they started to grow into two different creatures, although this is more considered making twins. The next experiment that is similar to this one is the one done by Hans Spemann in 1901 and he did the same thing with salamanders. Although many more experiments happened in the 1900s, a major breakthrough would have to be Dolly, she was the first mammal to be cloned and be

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.

For the past few years, scientists have been working on a cloning experiment. Cloning is where one thing is taken and and another one is made. One just like it. Mostly, animals have been cloned. They have been cloned with many fails, and some success.
