So far scientists have been able to clone salamanders, mice, flies and other living animals. The first cloned mammal was Dolly the Sheep. The cloning od Dolly came after many failures. The scientific team that produced the Dolly, first cloned sheep, reported that it took 277 eggs to produce 29 sheep embryos; of these only three survived until birth, and only one of these three - Dolly - lived for any length of time after birth. The cloning of Dolly the Sheep proved that genetic material from an adult cell could be used to grow an identical copy, or clone, of the entire organism.
