       History of Cloning
 started in 1954, when a tadpole
  was successfully cloned by two
  American scientists using nuclear
  transfer.
 1997-first cloned sheep, Dolly.
 In 2002, Greek scientist Dr. Zavos
  announced that his research was
  complete and was ready to
  successfully clone humans.
 As of now, human cloning is illegal
  in 23 countries.
      Current Developments
 In 1997 the sheep, Dolly, was cloned after
  277 tries and lived for 6 years
 A year later, 50 cloned mice were
  announced born in Scotland as well as a pair
  of cloned calves in Japan.
 From 2000 to 2003, Scientists achieved the
  goal of cloning pigs, a cat, rabbits and a
  mule.
 More recently, 13 yr old mountain goat has
  been successfully brought back to life.
 This past year, a bull was cloned in Japan,
  from the testicles of a dead bull, frozen
  thirteen years ago.
          Future Trends
 When will we be able to clone
  humans?
 about 1 or 2 of every 100
  experiments are failures.
 30% of clones that are a success
  have mental or physical problems
 They can mysteriously die and
  usually will live shorter lives
 We need to learn how to make
  healthy clones that will live longer
         Hypothetical Situation
             A family with a set of twin girls
    finds out 1 is suffering from liver failure
    and she is terminally ill. They have the
    option of cloning the health twin’s liver but
    there is a chance of her dying in surgery.
    Even though she will die in surgery she has
    a chance to save her sister because they will
    be able to use her liver. Do you risk the life
    of the healthy twin to save the ill one or
    not?
Who does this affect?
Does it do harm?
Does it do good?
Does it respect autonomy?
Is it fair?
This is what we think…
 We need to do more research
 No cloning animals or humans
 We want to be able to clone
  genes and organs once we
  perfect the operation
