   Dolly’s False Legacy
                                         Lead-in
                                                   Dolly:
           Photographs of a rather ordinary
           looking lamb named Dolly made
           front pages around the world
           because of her starling pedigree:
           Dolly, unlike any other mammal
           that has ever lived, is an identical
           copy of another adult and has no
           father.She is a clone, the creation
           of a group of veterinary
           researchers.

 More about Dolly:

That work, performed by Ian
Wilmut and his colleagues at the
Roslin Institute in Edinburgh,
Scotland.They accomplished their
feat by transferring the nuclei
from various types of sheep cells   complete set of genes, just as they
into unfertilized sheep eggs from   would if they had been fertilized by
                                    sperm. The eggs were then cultured
which the natural nuclei had been
                                    for a period before being implanted
removed by microsurgery. Once
                                    into sheep that carried them to term,
the transfer was complete, the      one of which culminated in a
recipient eggs contained a          successful birth.

            Debate



         Dolly’s birth thus represents an ethical and scientific
         watershed. Around the world, advisory committees and
         legislators are frantically trying to decide whether and when it
         might be ethical to duplicate the feat in humans. Traditional
         teachings that life begins at conception suddenly seem to be
         missing the point. President Bill Clinton quickly announced a ban
         on the use of federal funds for human cloning research .

      Fact:
         Cows, sheep and rabbits have also been cloned from
      embryonic cells in recent years, But producing healthy
      human clones may prove to be extremely difficult.Wilmut,
      who argues for a moratorium, on such attempts, points out
      that more than half the cloned sheep pregnancies he initiated
      failed to develop to term. Some had abnormalities.
                                They would probably produce
                               many unhappy customers and some
                               dead babies before they created a
                               live one.

                  Perspective:


         Wilmut concurs that there are no ethical grounds to justify
         duplicating existing humans. He even opposes allowing a couple
         to copy a child in order to get a source of tissue to save its life .
         Other bioethicists are more receptive to copying people. John C.
         Fletcher of the University of Virginia believes that society might
         find it acceptable for a couple to replace a dying child or for a
         couple with an infertile partner to clone a child from either partner.
