It has been few decades since the word “cloning” was first used in the science world. Though, the idea of creating an organism identical to another has been around for centuries. As matter of fact, the process of artificial cloning began in the 1900s. This was a major breakthrough in science, since gates were opened for scientists to freely make their desired organisms in lab. In the late 1990s, this major technology gets public attention, it raises concerns, and then becomes very ethical due to different beliefs people had. The 1997 birth of Dolly, the sheep, was the main reason why this achievement has lately taken a great deal in the media. After many debates over fraud and ethics, the FDA and other governmental or non-governmental organizations starts the heroic job of speaking for the people and what they want to see happening in science. This technology expands from Great Britain, where Dolly was made, to other nations with the possibility to clone humans which would later be immoral to many and somewhat unacceptable to others. What causes this dramatic change? Many scientists tempted to clone including Briggs and King in 1952, who, at the time, successfully cloned an amphibian, Rana Pipiens. It was done by taking the frog nucleus and injecting it in an egg, a process called nuclear transfer, where the egg’s original nucleus was removed (Briggs & King 456-457). The injected nucleus was experiencing differentiation. Differentiation is the process where new formed cells (ex: fetus cells) grow to fulfill a particular task in our organism (ex: form our digestive system). In the experiment, Briggs and King separates the frog embryo when it was two cells large, then each cell matures into adult organisms. This experiment and many more disproved Wilhelm Roux and August Weismann’s theory which stated that “the egg and sperm are the only which carries hereditary information and also the only to contribute to the formation of the embryo.” (Briggs & King 455). With this experiment, Briggs and King were able to prove that somatic (body) cells, too, bear all hereditary information inside them and can, therefore, be grown into a new organism. As some scientists try to discover new clues in this technology, others are ready to publish their success. This is in the case of Dolly, the infamous sheep, which was the first mammal cloned from an adult somatic cell. After many attempts and failures by Wilmut and Campbell at the Roslin institute, Dolly is a result of the cell taken from a mammary gland of a six-year old ewe, the ewe reminded the two scientists the large chest of Dolly Patron (Campbell n.p.). The world saw this major breakthrough, scientists started to think of new ways of how to upgrade this practice and make it life-leading. Lawrence Smith has written movingly of other major experiments which followed Dolly’s birth. And of course major achievements have downsides, Smith used one example of failure in placental development through his statement: Many aspects of embryo and fetal mortality seem to suggest that the placenta does not develop normally, possibly due to inappropriate transition from yolk sac to allantoic nutrition. Others have observed that the growth of the allantois (stage in embryo development) is severely retarded, or even nonexistent, as characterized by lack of, or reduced, vascularization during early gestation, leading to failure of normal placental dev
