Pros And Cons Of Cloning Animals And Humans

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.

The topic of cloning has brought much debate in science and also in society. Many

In fact, the very first experiment related to Cloning happened in 18th century, too, when scientist Hans Adolf Edward Dreisch an artificial embryo twinning of Sea urchin. In the experiment, Dreisch did nothing more than swinging the two-celled sea urchin embryo, and it splits into two complete cells which have full capability of growing into a complete organism. After that, scientists in 19th century,

The most notable example of early cloning came from a German embryologist named Hans Spemann. Spemann 's name will always be remembered, because of his work on experimental embryology. He mastered in micro-surgical techniques, and, working on the relatively large eggs of amphibians he discovered in 1924, working with Hilde Mangold. They discovered the existence of an area in the embryo, the portions of which, upon transplantation into an indifferent part of a second embryo. The name was therefore given by him to those parts.

Should people not be allowed to clone animals? Some people see cloning animals as bad, but some people see cloning as a good thing. Cloning should not be illegal because it has great future effects in daily life, saving endangered species, and scientist can use them as test subjects.

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.

Numerous attempts are being made in the hopes of finding an answer to the problem of the millennium. The concept of cloning has caught scientists attention throughout this past century. "The world has to come to grips that the cloning technology is almost here,” a representative for a European research group, Panos Zavos. Clones are life forms that have identical genetic coding. A clone is an organisms replica. Originating in the late 1880’s; the first record of synthetic embryo

Cloning in animals is described as “number of different processes that can be used to produce genetically identical copies of a biological entry” (“Cloning Fact Sheets”). In animal cloning, a wide variety of biological aspects have been cloned such as genes and tissues. Upon researching this subject, some of the most commonly asked questions was about if and how do clones happen naturally? In nature, there has been a long history of mutations and “natural” clones. Cloning is commonly seen in asexual reproduction as bacteria often reproduce identical copies. A real-life example of natural clones is seen in identical twins. These twins are seen as identical copies as well observed in both humans and other mammals.

Human cloning has advanced dramatically over the years. The first breakthrough in science was cloning a sea urchin in 1885. It

Dolly the sheep was the first mammal to be cloned, her birth being announced on February 22, 1997. She was created by a group of scientists from Scotland where she lived for six and a half years before being euthanized due to progressive lung disease and severe arthritis. Dolly was

On February 24, 1997 history was made. The first cloned adult mammal was born through somatic cell nuclear transfer (McCuen, 11). Somatic cell nuclear transfer is when a nucleus of a mammary gland is removed and fused with an egg by using electrical pulses. The pulses prompt the egg to divide to form an embryo. The embryo is then transferred to a uterus where it is implanted to grow (McCuen, 10). Before the creation of Dolly, many scientists were unsuccessful in their attempts to produce a genetically identical copy of a cell. In the rare occasion that they were successful in their attempts, they would soon be discouraged due to the inability of the clone to sustain life. It took hundreds of attempts before Dolly’s team of scientist could obtain a successfully cloned sheep. Of the 277 successful transfers, only 29 became embryos. And of these 29 embryos, Dolly was the sole survivor (Sweat, 1). What sets Dolly apart from previous clones is the fact that she was cloned differently. Dolly was cloned not from sex cells but from mature mammal cells with no reproductive function (Sweat, 1). Even though Dolly was a

Structure, function, and growth discoveries in biology happen every day. Humans have always questioned if we have the technology and capability to manipulate life. Questions such as: Can scientists replicate DNA and get rid of diseases in DNA? Can we create an almost perfect species? Could we live in the world, where animals are never endangered, and ecosystems would be plentiful of life? A place where cloning animals are improving our way of living and advancing our technology. Yet, in many places around the world cloning on animals, especially humans, there is ban from any sort of experimentation. In the article Dolly the Sheep’s Fellow Clones, Enjoying Their Golden Years, we peek into the misconceptions people have about cloning experimentation.

Cloning, an ethical issue that has been pressed across the globe, has become a substantial debate throughout a majority of nations. The incorporation of a new type of reproduction in the United States has a plentiful amount of benefits for certain animals and objects, but duplicates of humans is hard to comprehend for many people across America. Currently, cloning is an interesting topic that could become a new way to improve reproduction of animals and humans, prevent diseases, and increase the overall health of Americans.

Misconceptions are held about cloning. Most people globally tend to believe that cloning is pain free, not mistake prone and is only done in laboratories for research. In reality, the first successfully cloned animal known as Dolly the sheep, was successful after twenty-seven

If a random individual were asked twenty years ago if he/she believed that science could clone an animal, most would have given a weird look and responded, “Are you kidding me?” However, that once crazy idea has now become a reality, and with this reality, has come debate after debate about the ethics and morality of cloning. Yet technology has not stopped with just the cloning of animals, but now many scientists are contemplating and are trying to find successful ways to clone human individuals. This idea of human cloning has fueled debate not just in the United States, but also with countries all over the world. I believe that it is not morally and ethically right
