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
