Cloning
Since the late seventies scientists have been cloning mammals using cells taken from embryos. In July 1996, medical history was made when a sheep named Dolly was cloned. The only thing that set Dolly the sheep apart from the other clones was that she was cloned from an adult sheep cell. Before Dolly was cloned, scientists thought adult cell cloning was impossible. A clone is defined as a group of genetically identical cells. The goals and purposes for cloning range from making copies of those that have deceased to better engineering the offspring in humans and animals. Cloning could also offer a means of curing diseases. Cloning has many benefits that could be used as an aid to the human race, but there is also the ethical debate over cloning. Many people believe it will do damage to mankind. Some feel it is against God's will, while others fear deformity and emotional stress in the human clone. Despite the ongoing debate, cloning produces many advances for the human race.Cloning has already made advances from the cloning animals. Embryo splitting was developed in the eighties and is used by ranchers and livestock breeders. Through this process, farmers can twin their best animals and plants for better production
They can also provide for much needed drug substances using transgenic animals. Tissues and organs could be cloned by using embryonic stem cells to take place of the damaged tissues and organs. Diseased children would also be given a second chance by having a clone to use for transplants. Many diseases are caused by a flaw in the gene. Steps have already been taken implies Dr. "Medical Benefits of Cloning" said that many animals are also being bred to provide organs for organ transplant patients. Scientists can grow skin more easily than other tissues and organs because skin cells are able to divide and produce new cells better than others. Animals could be cloned to provide better livestock, drugs, and organs for human transplant patients. Infertility treatments are only successful about ten percent of the time. Accident victims who require reconstructive surgery would have safe bone and tissue that their body would take as it's own and would not reject. They would then be able provide nerve cells for spinal injury victims or muscle cells for heart attack patients. "Benefits of Human Cloning" says that cancer could also be cured through the cloning technique. Clones could also be used for spare parts. Animals could be mass produced to provide a much faster and leaner species using cloning technologies. Cloning animals has proved to have many benefits also for humans.
