Exactly 15 years appeared in the famous sheep Dolly. Successful cloning of its experiment, performed in the laboratory, the Scottish scientist Jana Vilmuta, became a worldwide sensation. Clone sheep caused a storm of emotion, resentment, fear and disappointment. But the real bomb of public opinion was the prospect of cloning humans. Disputes on the subject does not subside even today.
After Dolly appeared clones of various mammals: cats, dogs, horses, even primates. Today's scientific level and allows the cloning of humans, according to Director of the Institute on research and development noosferna Boris Rezabek.
The scientific part of the question is clear, but its ethical side is much more complex and deeper than people imagine sometimes. Our world is pretty crazy. It is quite possible that some psychopath with a lot of money power in a secret laboratory to clone humans. But the point is I do not see any.
Research on human cloning are unacceptable because in the process of trial and error can occur many imperfect clones, namely a person for various disorders. In addition, the cloning experiment. Experiments in which the experimental rabbit man, is inadmissible without the free and voluntary consent. And this is not the only moral character. That is why in many countries, including in Russia, human cloning is now banned.
The second thing is the cultivation of cells and even human tissue, according to Boris Rezabek.
Unfortunately, our body is subject to many diseases. And it happens so that the body must be replaced. There is a whole science - transplantologi. But to get the material from the donor is a serious problem. This phenomenon rampant crime. When literally kill people in order to get an organ, sold it for huge amounts of money.
From the standpoint of science, any form of cloning, whether to fly, mouse, horse, sheep, or an elephant, an interesting task. But ethical issues aside to be considered by society as a whole. It is quite possible that some cloned animals become extinct and it is for science a matter of paramount importance.
Reproductive cloning is already actively used for creating primereka agricultural and domestic animals with unique oslobinama. If you are in South Korea at the customs used Labradors obtained by cloning a dog with a particularly subtle flair. Today, using this method preserved and rare species of animals.
As for the sheep Dolly, she lived about six years, two times less than you normally live sheep. She had lung disease and severe arthritis. Star genetics had to be asleep to not bothering. But the 2007th Dolly was born again. This time, the surviving sheep cells were obtained immediately four healthy clone. They are exactly the same as Dolly, but at the same problems that have followed her in life. Clones do not suffer from arthritis and sick lungs. Four new Dolly are still alive and well.
