DARYN KAGAN, CNN ANCHOR: We get a peak into the future with today's look back at CNN's history.</s>ANNOUNCER: Bringing you the world for 20 years, this is CNN.</s>JEANNE MESERVE, CNN ANCHOR: It sounds like science fiction: scientist taking a cell from one living being and making an exact copy in the process called cloning. Now for the first time, researchers have cloned an adult mammal.</s>SIOBHAN DARROW, CNN CORRESPONDENT: Well, when we first heard about Dolly the cloned sheep, it was as if science fiction had come true and everyone was painting all kinds of nightmare scenarios. But when I went there and looked Dolly the cloned sheep in the eye, it was really quite extraordinary. It was like having a glimpse of the future.</s>IAN TAYLOR, SCIENCE & TECHNOLOGY MINISTER: What we need to put in place are some careful frameworks to ensure that we don't go from the excellence of the science into something that the public would consider to be science fiction.</s>DARROW: To actually clone, to have a manmade creature, living, breathing creature, is an extraordinary step. It's forced me to really reevaluate and look at the future and realize that this is something that's very likely might be in our future.</s>NICK SHORT, BIOLOGY EDITOR, "NATURE" MAGAZINE: From the public perspective, it's almost shocking: Suddenly it's making it obvious that you can do a whole lot of things that nobody ever quite thought you could.</s>DARROW: Every story is interesting, has its own merits, but Dolly was a symbol of a new era, of the new millennium, of the future. And she's a real turning point. And I felt privileged to be in her presence.
