Human cloning no longer seems as fantastic as some 20-30 years ago. In this issue we will talk about how far scientists have advanced on this issue and how soon we will be able to grow clones for ourselves.
Let’s begin, perhaps, with our smaller brothers because animals show the main successes in questions of cloning. Of course, we could not overlook Dolly the sheep, which became the first cloned mammal in the distant 1995. And on January 24 of this year, scientists from China officially reported on the successful cloning of the monkey, which significantly brought mankind closer to creating their own copies. But such scientific experiments are primarily aimed at studying genetic diseases and new methods of combating cancer diseases that kill millions of people every year.
Newborn clones often suffer gigantism, defects in the liver, heart and brain, due to which animals simply die. This is one of the main aspects that interfere with human cloning. Also, thanks to science fiction, people think about the absolute identity of a clone, not only in appearance, but also, for example, in character. Unfortunately, this factor cannot be controlled, because Human consciousness is far from being shaped only by genetics.
If we talk about the complete cloning of human DNA, then such procedures are prohibited in most countries, which at the same time does not hinder the development of genetics. Scientists have managed to preserve human cord blood and grow stem cells from it. But they are the building blocks for growing new organs. At the moment, humanity already has experience in transplantation of not only skin and bones, but also artificially grown bladders and trachea.
It will be important to note that there is another way of cloning, which causes a huge amount of controversy in society. This is the cultivation of a full-fledged human embryo consisting of about 100 cells. Its biomaterial is suitable for growing organs and other therapeutic purposes. However, such procedures are allowed only in the USA, India and the UK, as well as in some parts of Australia.
In conclusion, it is also worth noting that despite the development of technology, we still live in a deeply religious society. The Pope and the Patriarch of the Russian Orthodox Church are opposed to a person trying on the role of the Lord, and the lack of guarantees of the viability of the fetus, makes us think about the ethical nature of cloning. All these factors, as well as various international conventions, are unlikely to allow a person to lawfully clone in the next century, which, of course, will not prevent secret experiments that are likely to be conducted by transcontinental medical corporations.
