The new embryo was placed in a surogatte mother sheep and a few months later, Dolly was born. Before Dolly and the cows, several clones had been made of smaller mammals and other lower animals. Gentically identical rats have been used in research for years and clones of tadpoles date back to the fifties. Until Dolly though, many scientists believed it would be impossible to ever clone an adu lt human. It now appears that they were wrong and, barring a few technical issues, human clones will be possible by the turn of the century.
Cloning is a very valuable technology but also a very misunderstood one.
Unlike what was seen in the motion picture Jurassic Park, it is not likely that we will be able to clone dinosaurs. We have no dinosaur DNA from which to make these clones. For similar reasons, cloning dead people will only be possible if the body is fresh or has bee n preserved extremely well. Frozen corpses like the woolly mammoth found a few years ago might be possible candidates. Of course a suitable host mother would have to be found.
