Cloning Of HumansBio engineering is one of the sciences that have been for a while in the spotlight when it comes to the public opinion and the media. Genetic cloning became one of the most controversial issues linked to bioengineering. The first successful cloning in mammals, the famous Dolly the sheep case has brought up to the attention of the people that there might be more to science than it was known until the 1990s. Many species of animals have however been cloned or attempted to be cloned along the time, but when it comes to cloned people the issue suddenly becomes more sensitive.
Human cloning entails the creation of a different individual, a genetically identical copy of an already exiting human being. Specialists also refer to the process of human cloning as artificial human cloning as natural human cloning does exist and are commonplace, namely the existence of identical twins. Two commonly discussed types of human cloning can be distinguished, one of them being therapeutic cloning and reproductive cloning. The first terms is used to describe the process of cloning in which adult cells are being cloned for therapeutic purposes and for their use in medicine. A common such procedure is the cloning of the stem cells which plays nowadays an important part in the research regarding potential cures for different previously incurable conditions. Reproductive cloning on the other hand is the term specifically used to refer to the artificial cloning of humans. Moreover, a third type of human cloning may be identified, though only in theory. This would be the replacement cloning which would be performed as a combination of reproductive and therapeutic cloning in order to replace a failing body.
The first ever hybrid human clone is known to have been created in the late 1990s. It had been however destroyed 12 days later.
