Cloning

Cloning has always been a very controversial ethical issue. At the beginning, it has always believed that it was a phenomenon that could only happen in Sci-Fi movies, but with the advances in technology this idea would become a fact and probably possible solution for the health of humans and animals.

Initally the cloning appears in 1952 through an experiment conduced by scientists at the University of Pennsylvania that consisted of introducing genetic material from one frog into the ovule of another frog, This experiment was successful and later they began to clone rats and bigger animals like pigs. 

The most particular and controversial case was the case of  Dolly the sheep, who was cloned in 1996 and the news was released months after the sheep was born. The particular thing about the Dolly case it was cloned from the genetic material of the udder of the original sheep, wich showed that the clonning cold be done from any cell in the body of the animal.

In my opinion, cloning is a very useful tool that can be used especially for medicine and generate tissues ans organs for people who need it based on their own cells, so there would always be compatible and would generate shorter waits for an organ, where many people die waiting. Contrary to I said before, I think that cloning should not be to duplicate people or animals because the essence and personality of each subject is unique and unrepeatable and a ''copy'' can't replace the original.
