Cloning has been a controversial subject for some time and is only starting to be clearly defined by the masses. There are two distinct sides of cloning: animal and human. Animal cloning is defined in technical terms as "a means of asexual reproduction where a single cell in made to grow into an animal genetically identical to the animal that donated the cell" (Weiss, A-16) Human cloning is basically the same, yet there are more complications associa

The research that has gone on has had some exciting successes and some terrible let downs. In cloning "scientists harvest an unfertilized egg from a female donor, removing the genetic material and replacing it with new DNA from an adult cell of an animal [or human] to be cloned. An electric shock coaxes it into dividing" (Neegaard, A-8) and the egg can grow into a much younger identical twin of the donor. The first successful clone was Dolly the sheep. Though, it took 277 attempts before she was born and healthy. Scientists have also been able to create cats, cattle, pigs, goats, mice and other farm animals. This doesn’t go without saying that the clones had significant abnormalities and brain damage. Respirators and feeding machines had been hooked up to these animals, some right out of the womb. Just recently a colt was created from a mare donor. This was a great advance in the science. Humans, however, pose a great risk in cloning because of their molecular structure. In December a cult group was said to have cloned a human but these reports were never verified. Leading up to human cloning, animals have been the "test group" in the field of genetic engineering.
