Cloning is a very controversial theme. It is considered by many people and nations as an immoral practice, a bad appendix of science. Cloning does violate the laws of nature, because we are the ones that manipulate it. It interferes with the natural and common reproduction. But we have to consider another point of view. What will happen to the people who can't procreate by the traditional way, nature's way? Don't they have the same rights with us to become happy, to fulfill their wishes of becoming a father or a mother? How can we stop people from practicing the universal right of searching for happiness? If we do it, we would be selfish. That's why cloning could be a solution to that dilemma.
We should proceed this debate with the history of cloning. The modern era of laboratory cloning began in 1958 when F.C. Steward cloned carrot plants from mature single cells placed in a nutrient culture containing hormones. The first cloning of animal cells took place in 1964. John B. Gurdon took the nuclei from tadpoles and injected them into unfertilized eggs. The nuclei containing the original parents' genetic information had been destroyed with ultraviolet light. When the eggs were incubated, Gurdon discovered that only 1% to 2% of the eggs had developed into fertile adult toads. The first successful cloning of mammal was achieved nearly twenty years later. Scientists from Switzerland and the U.S successfully cloned mice using a method similar to Gurdon's. In 1993 the first human embryos were cloned using a technique that placed individual embryonic cells in a nutrient culture where the cells then divided into 48 new embryos. These fertilized eggs did not develop to a stage that could be used for transplantation into a human uterus.
