Her birth caused a sensation around the world cause it was the first time that scientists had cloned an animal from another adult animal. Her death in 2003 opened discussion about the moral problems of cloning. addition, scientists wanted to do more research to discover if Dolly had died early because she was a clone. Normally sheep live for about eleven or twelve years, but Dolly was only six when she died. Did that mean that she was already six when she was born? Interestingly, the sheep the scientists used to clone Dolly was six, so perhaps Dolly had the same genetic age? Dolly had four healthy lambs, but scientists discovered that Dolly suffered from arthritis in her legs. A virus caused her main illness. However, we don't know for certain whether cloning always creates naturally unhealthy animals. There are scientists who want to experiment more in order to learn the truth. Cloning may become a way to save animals which are in danger of extinction. In January 2009 scientists from the Centre of Food Technology and Research of Aragon, in northern Spain, announced the cloning of the Pyrenean ibex. Unfortunately, the cloned ibex died shortly after its birth. It might also be possible to re-create animals which no longer exist. So don't be surprised when you see a dinosaur the next time you go to the zoo!
