| Tony: These days, the word "clone" has been seen very often in the newspapers. Do you know its meaning? Lana: I read a report. It said that Dr. Ian Wilmut successfully cloned a lamb named Dolly from a grown-up sheep. So people call him the "father" of Dolly. Tony: In fact, the word "clone" means to produce the "same" animal by taking cells from a grown-up one. I think, if we know how to do cloning, we need only to keep a small number of sheep, cows or horses. Lana: What's more, these days some people even want to clone humans. They have asked: Can we clone ourselves? Tony: It seems interesting. But do you think it possible to do that? Lana: No, impossible! First, I think we cannot clone a dead person, because the cells in his body are dead already. Tony: Then can we clone a living person? Lana: Again no! You might clone yourself one after another, but it is only a copy, not a real you. It is only something, not a "human". Tony: Well, you mean that it is not a real human. Lana: True enough! I think Dr. Wilmut would most like to make better animals, and it has nothing to do with human cloning. |
