The term \u2018clone\u2019 was first used by J.B.S Haldane, a British biologist, in 1963. A \u2018clone\u2019 is a genetic copy of an organism, and \u2018cloning\u2019 involves the various processes used to create clones. Cloning is actually a very common process of reproduction for micro-organisms and plants. Reproduction isn’t truly cloning when it comes to multicellular organisms like animals and humans – primarily because of the variations involved in cellular copying. But when humans begin to indulge in it artificially – it comes with a lot of issues, both scientific and ethical. Human cloning is looked at with contempt and anger, almost uniformly by governments all over the world. Why though?<\/span><\/p>\n\n\n\n

The simplest brief on how human cloning works goes something like this: An egg cell, whose nucleus is removed, is fused with the nucleus obtained from a another skin cell – they are treated with a gentle electric shock after which the eggs divide and develop into a multicellular embryo which further develop into a foetus, and\u00a0 at last, upon its birth, we have a clone!<\/span><\/p>\n\n\n

Have we been successful at human cloning?<\/span><\/h2>\n\n\n\n

If we delve into the history of animal cloning, the first name that would strike us is probably Dolly the sheep. Dolly was the first successfully cloned mammal created from a cell taken from an adult sheep in 1996, thus its celebrity status. Preceding this achievement was the cloning of the first animal – a sea urchin, which was successfully done way back in 1885 by Hans Adolf Edward Dreisch. Quite a lot of animals have been successfully cloned since the 1960\u2019s \u2013 mice, rabbit, buffalo, cat, rhesus monkey, pigs and even dogs. In 2009, the first mammal from an extinct species \u2013 Pyrenian ibex<\/em>, was cloned which lived for only a few hours.<\/span><\/p>\n\n\n\n

In 2004, a group of South Korean scientists claimed success in cloning a human embryo, which later turned out to be a false claim. Then in 2011, Mitalipov and his colleagues of the Oregon Health and Science University reported the successful cloning of a human embryo, which was allowed to develop up to the blastocyst stage, using the same technique that was used to clone Dolly. This experiment, which used somatic cell nuclear transfer (SCNT) was an important breakthrough in human cloning research. Theoretically speaking, we have all the materials and working methods for human cloning, and scientists are confident that human cloning is possible! It\u2019s just a matter of \u2018when\u2019.<\/span><\/p>\n\n\n\n

And when it comes to the aspects of cloning animals we have two forms \u2013 \u2018reproductive cloning\u2019 and \u2018therapeutic cloning\u2019. Reproductive cloning involves the production of a fully developed clone for reproductive purposes whereas therapeutic cloning, often referred to in discussions about medical advancements, focuses on research and medical purposes, including the potential for applications in human cloning.<\/p>\n\n\n

So why aren’t we going all guns blazing on cloning? Because of the huge ethical ramifications and debate it lights up. A large number of people seem to agree on us not playing God. Most of these arguments arise from religious inclinations. But others are sourced from our current legal structure as well. Cloning isn’t 100% reliable – we could be creating deformed, handicapped humans for whom existence is a curse. In such cases, the more prudent thing to do would be to put them to death – but are we allowed to commit murder under the pretext of the victim being a clone?<\/span><\/p>\n\n\n\n

What if human cloning is made legal?<\/span><\/h2>\n\n\n\n

What if we finally reach the era where we have the complete right to create clones? \u00a0Will that be safe? What\u2019s the big issue about human cloning?<\/em><\/span><\/p>\n\n\n\n

If cloning (both reproductive and therapeutic) is legalized, then it means we can. . .<\/span><\/p>\n\n\n\n

    \n
  • Produce cloned children which will benefit same-sex couples, infertile parents and those who had lost a child.<\/span><\/li>\n\n\n\n
  • Save species that face the danger of extinction and even revive an extinct species like the mammoth!<\/span><\/li>\n\n\n\n
  • Boost up our speed of recovery from traumatic injuries by generating our own cloned cells.<\/span><\/li>\n\n\n\n
  • Grow organs that we require for replacement that will suit our needs. Organs will be available for order according to individual needs.<\/span><\/li>\n\n\n\n
  • We can eliminate defective genes and choose specific traits for our clones. Artificial selection will be at a high speed.<\/span><\/li>\n<\/ul>\n\n\n
    \n

    But! On the other side of the coin. . .<\/span><\/p>\n\n\n\n

      \n
    • Only about 5% of the attempts to clone animals have been successful. We can take the example of Dolly whose cloning was a success only after 277 attempts! And there also lies the possibility of premature ageing of clones. So, safety is still a big question.<\/span><\/li>\n\n\n\n
    • Cloning may reduce the value of life and uniqueness of individuals as clones will be easily available like a commodity. It is possible that we may face identity crisis.<\/span><\/li>\n\n\n\n
    • Cloning technology can be misused if it lies in the wrong hands as clones can be created from the skin cells we shred every day. This can be a serious threat.<\/span><\/li>\n\n\n\n
    • There will be religious outrage and the faiths of many will be challenged as we will actually \u2018play God\u2019 and create human copies.<\/span><\/li>\n\n\n\n
    • Scientists are worried that there will be a decrease in the diversity of our gene pool and this can have misleading effects for our kind.<\/span><\/li>\n<\/ul>\n\n\n\n

      How soon can we clone humans?<\/span><\/h2>\n\n\n\n

      Currently, different countries around the world have viewpoints regarding the cloning of human. Over 30 countries have laws that ban reproductive cloning and more than 20 countries declared therapeutic cloning as legal. Many of the other countries have no formal law regarding the legalization of human clones. The Universal declaration of Human Genome and Human Rights by UNESCO states, in Article 11, that: \u201cPractices which are contrary to human dignity, such as reproductive cloning of human beings, shall not be permitted. . .\u201d<\/span> <\/strong><\/p>\n\n\n\n

      Scientifically, we are ready to create clones; but, are we \u2018socially\u2019 ready? This is one of the questions that still put to hold the legalization of human cloning. The ongoing debate mostly lies on the ethical perspective rather than scientific.<\/span><\/p>\n\n\n\n

      Human cloning is still a controversial issue for most countries and individuals. Scientists and futurists, however, are confident that in the near future we will be able to legally create clones. <\/span><\/p>\n\n\n\n

      So, what\u2019s your stand regarding the cloning of human? Do you think we are really ready for this?<\/em><\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
