ortly after birth. Clones that do make it through the crucial first months wind up suffering from chronic or even fatal genetic irregularities: "Some clones have been born with defective hearts, lung problems, diabetes, blood vessel problems, and malfunctioning immune problems" (howstuffworks.com). In Dolly's case, she suffers from recurring hyperventilation because she has malformed arteries that lead to her lungs.
             Scientists argue that eventually the rewards will outweigh the risks. Animals will be used to create drugs to prevent human diseases, or actually grow human organs for future transplantation (CellNEWS). Sheep are already being cloned to produce human insulin. If sheep were reproducing naturally, the desired traits would be bred out since sexual reproduction "reshuffles" the genetic cards. Cloning the sheep with the desired traits ensures that nothing will change throughout the offspring. In 2001, the first endangered species was cloned. Noah, a baby bull gaur (a large wild ox from India) was cloned successfully, proving that endangered species
             can be saved through cloning, another reward scientists rapidly added to their list (howstuffworks.com). The world of animal cloning has already begun to provide many possible scientific advances. But it is nothing compared to what may come with further advances in human cloning. Human cloning already occurs naturally, with the births of identical twins, but scientists have been experimenting with ways to use somatic cell nuclear transfer. It "begins when doctors take the egg from a donor and remove the nucleus...creating an enucleated egg. A cell...is then taken from the person who is being cloned. The enucleated egg is then fused together with the cloning subject's cell using electricity" (howstuffworks.com). The embryo is hence created and placed into a surrogate mother. If the procedure is successful, at the end of t...
