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.
