If a Jurassic Park opened up in the real world it's obvious that there would be a backlog of visitors as long as a strand of DNA. Provided that there was considerably more security than in Steven Spielberg's film it'd be a great day out for all the family, even if the little uns might find the T-Rex eating a live goat more than a little disturbing. Unfortunately, if real science has anything to do with it, a real life Jurassic Park is never going to happen. At least, not in the way it does in the film, by reconstructing the ancient beasts from DNA found in the bodies of prehistoric mosquitoes preserved in amber. No matter how well preserved the insects might be, DNA itself degrades over several million years and would be useless to even the most intelligent boffin around. Still, more recently extinct animals could be brought back to life with a similar process - theoretically, at least - although "Woolly Mammoth Park" doesn't have quite the same ring (not to mention the fact it could be achieved far more cheaply with a few elephants with blankets draped over them...)
