ARGUMENTITIVE PAPER - search ExampleThe continued re-create of animals is essential because this method will provide a more literal and beneficial food source for a growing world population as does the cloning of plants. However, the cloning of humans is not in societies or an individuals best interest, at least not yet.On February 23, 1997 Ian Wilmut, a Scottish scientist, with his colleagues at the Roslin Institute announced the productive cloning of a sheep by a new method. The technique concerned transplanting the transmissible material of an adult sheep into an egg from which the substance had been removed. The resulting stomach of the sheep, chick, was another landmark in mankinds ability to rule over nature. The birth of Dolly and the fact that humans might someday be cl unrivalledd, created from a single somatic kiosk without sexual reproduction, moved further away from science fiction and closer to a genuine scientific possibility (Wilmut, 1997).The sheep experiment was different from prior endeavors in that it produced an animal that was a genetic twin of one adult sheep instead of being the identical offspring from a pair of adults. Dolly was the first successful clone of a mammal as the sheep contained the genetic material of just one parent. For more than 40 years, the practice of transferring a nucleus from a somatic cell into an egg using nuclei derivative from non-human embryonal and fetal cells continued. Evidence suggested genetic material contained in differentiated somatic cells may retain the capability to direct the development of healthy fertile adult animals. Biologists had examined whether, once cellular differentiation transpires, this process is reversible. However, until Dolly was born, the capacity to do so remained unproved. The demonstration that nuclei from cells derived from an adult animal could be reprogrammed, or that the full genetic complement of such a cell could be
