[05:39.26]scientists believe they may be able to create a
[05:42.61]a plentiful source of organ donors for people.
[05:46.97]11  Why not clone humans as organ donors?
[05:52.26]Theoretically, Wilmut says,
[05:55.57]there is no reason his techniques couldn't someday be used to clone people.
[06:01.44]Think about the possibilities:
[06:04.82]a whole basketball team of Michael Jordans,
[06:09.29]a scientists panel of Albert Einsteins,
[06:13.57]a movie starring and co-starring Brad Pitts.
[06:19.22]12  On a more serious note,
[06:21.28]some experts argue that couples who have difficulty having a baby
[06:26.14]could make copies of themselves.
[06:28.98]And parents whose child has a fatal disease
[06:33.05]like cancer might be able to clone the child,
[06:37.30]creating a twin who could be a bone-marrow donor.
[06:41.76]13  But even Ian Wilmut draws the line at cloning humans.
[06:48.46]"All of us would find that offensive," he says.
[06:53.14]Several countries, including Britain,
[06:56.38]Denmark, Germany, and Australia,
[06:59.15]have made all scientific work on cloning humans illegal.
[07:04.44]The U.S. has no such law,
[07:07.61]but President Clinton has set up a panel of scientists
[07:11.82]and philosophers to study the issue.
[07:15.10]In the meantime,
[07:17.54]Cliton has imposed a ban on using federal money to clone humans.
[07:23.70]14  Humans are more than the sum of their genes,
[07:28.27]argues a philosopher at one research institute.
[07:31.80]Though they look exactly the same,
[07:34.64]clones are not necessarily exact copies.
[07:39.11]The younger twin might grow up with different influences
[07:43.86]— say,unusual friends or special teachers.
[07:47.86]A cloned Albert Einstein might fail his physics class.
[07:53.11]A cloned pop star might sing terribly.
[07:57.47]15  Say you were cloned.
[08:00.85]Would your twin live a shorter life
[08:03.73]because he or she started out with DNA that was already 10,
[08:09.24]20, or 30 years old?
[08:11.80]Scientists aren't sure.
[08:14.53]And how could you prevent someone from taking a sample of your hair
[08:19.61]and making a clone of you?Again, no solutions.
[08:25.26]16  Some people who oppose cloning
[08:28.97]also object to the use of animals as research tools.
[08:33.72]"Next, they'll be cloning foxes to make more fur coats,"
[08:38.47]says the president of an animal rights group.
[08:42.36]17  What do you think?
[08:45.42]Should scientists be allowed to clone animals?
[08:49.67]How about humans?
