able to conduct a simple cloning, he was never able to explain his findings and eventually gave up and switched his area of study to philosophy. In 1952, Robert Briggs and Thomas J* King, who were scientists in Philadelphia, were the first to implant a nucleus into an egg cell, using the nuclei of Leopard Frogs eggs. Unfortunately the procedure was unsuccessful, but in the early 1970s Dr. John. Gurden successfully transferred the frog nuclei and was able to develop the frogs eggs into tadpoles. Scientists announced in 1981 that they had transplanted mouse nuclei of embryos into mouse eggs: however, these findings were deemed fabricated after several other scientists tried and were unsuccessful. Other than the two findings described, few other experiments during this time period were successful, or even conducted. Most scientists of the late seventies and early eighties had determined cloning of embryonic mammal cells to be impossible. These views were drastically changed in 1984 when Dr. Steene Willadson reported successfully transferring nuclei from a sheep embryo to produce clones. Following this success, Dr. Willadson went on to successfully clone cow and monkey embryos in the same manner. Developing upon Dr. Willadsons findings, in 1994 Dr. Neal First developed cows by nuclear transfer from much more developed embryos that had ever been previously used. His next historical feat was cloning and producing Megan and Morag, the first cloned sheep from embryo cells. Chances are, the first thought that enters an individuals mind when discussing cloning is Dolly, the sheep that made headlines all over the world in 1997. Obviously, this was not the first cloning to ever take place, but what was momentous about Dolly was that they had cloned a mammal from an adult cell. Dr. Ian Wilmut and Dr. Keith Campbell did this, both embryologists in Edinburgh, Scotland. The two were able to clone dolly by placing the mammary cell of a sheep...
