2If we can clone sheep and mice, can we clone
humans?
3Definition of Personhood
- Biological Criterion (Francis Crick)
- If a child were considered legally born when two
days old, it could be examined to see whether it
was an acceptable member of human society
4Definition of Personhood
- Cultural Criterion Ashley Montagu
- A newborn baby is not truly human until he or
she is molded by cultural influences later.
5Definition of Personhood
- Mental Criterion (Joseph Fletcher)
- Humans without some minimum of intelligence or
mental capacity are not persons
6Sanctity of Life vs. Quality of Life
7Key Questions
- Who will decide?
- What criteria will we use?
- Will our standard stay permanent?
8Why is cloning so difficult?
- All the cells of your body are differentiated.
Stomach cells, brain cells, liver cells, muscle
cells never change into something else.
9Why is cloning so difficult?
- But the DNA in all cells of your body is the
same. The instructions to make you over again are
present in each of your cells.
10Why is cloning so difficult?
- But in brain cells, for instance, only those
genes needed for brain cell function are turned
on. Everything else is switched off. - It was a mystery as to how to turn all those
genes on again to form a new organism
11Why is cloning so difficult?
- Cloning frogs was mildly successful in the 60s
and 70s - But attempts in the early 1980s to clone sheep,
cows and mice were unsuccessful despite one
dubious report of success with mice. - The cloning of mammals, by simple nuclear
transfer, is impossible. Davor Solter, SCIENCE,
Dec. 1984

13Cloning Dolly
starved
fusewith
Mammary gland cell
enucleated egg
potential embryo
14Scientific Issues - Sheep
- Inefficient - 277 fusions, 1 lamb
- How long will Dolly live?
- Will Dolly be fertile? Yes!
- Other clones are large and fragile with subtle
genetic abnormalities - Some questioned Dollys authenticity but this was
answered recently.

16How were mice cloned?
17How were mice cloned?
18Cloned mice
19Scientific Issues - Mice
- Success rate is 2-3 compared to 0.3 for Dolly.
- Attempts to clone neuronal and testicular cells
were unsuccessful. - Successive generations were cloned.
- Technique more applicable to humans.
20Why Clone Animals?
- Sheep are being cloned to reproduce genetically
engineered sheep. These sheep are engineered to
mass produce human proteins in their milk.
21Why Clone Humans?
- Doug Dorner, sterile because of leukemia
treatment at age 16 The more he read the more
excited he got. Technology saved my life when I
was 16, he says, but at the cost of his
fertility. I think technology should help me
have a kid. Thats a fair trade. Time,
2/19/2001, p. 51
22Why Clone Humans?
- Randolphe Wicker, 63 I can thumb my nose at
Mr. Death and say, You might get me, but youre
not going to get all of me, he says. The
special formula that is me will live on into
another lifetime. Its a partial triumph over
death. I would leave my imprint not in sand, but
in cement.
23Why Clone Humans?
- Jack Barker, Minneapolis marketing specialist,
36, says, Ive come to the conclusion that I
dont need a partner but can still have a child,
he says. A clone would be the perfect child to
have because I know exactly what Im getting. - Â
- Cloning, he hopes, might even let him improve on
the original I have had bad allergies and
asthma. It would be nice to have a kid like you
but with those improvements. p. 55.
24Why Clone Humans?

Travis Silva
Same sex couples Christine DeShazo Michele Thomas
25Why Clone Humans?
- Why not? Were just another animal species?
- Children for childless couples
26Why Clone Humans?
- We can learn a great deal about human embryology
27Why Clone Humans?
- Some have suggested that cloning could replace a
deceased child
28Why Clone Humans?
- Clones could be a source of rejection-free organ
transplants
29Why Clone Humans?
- Cloning could create extra copies of desirous
individuals
30What is Life?
- There is no clear-cut definition for what is
life. And this is something, I think, that
society is going to have to think about, is going
to have to make some definitions. And those
definitions may not be permanent, they may change
as new technologies are developed. There is a
fine line, and the line, at the early stages, is
really based on your intentions of what they are
to be used for as opposed to necessarily what
they are.
31What is Life?
- So the question of what is life seems to change,
I think, in peoples minds based on what their
concerns are or their own interests are in how we
might use whatever it is we are producing. - James Robl, Quoted in The Cloning Revolution,
Films for the Humanities and Sciences (1998)
32Biblical Principles
- Genesis 126-28
- Created in Gods Image
- Therefore we are distinct from the animals
- Stewardship
- Exhortation to be fruitful and multiply
33Naturalistic/Evolutionary Principles
- An organisms sole purpose is to survive and
reproduce - We are just another animal species
- The species persists through time
34The Ethics of Cloning
- Usefulness of animal cloning
- Distinction between animals and humans
- Wastefulness of experimental process
- Cloned expectations
- Mythical reproductive rights
35Usefulness of Animal Cloning
- Reproducing genetically engineered animals to
harvest them for pharmaceuticals and organs for
transplant. - Preserve endangered species
36Usefulness of Animal Cloning
- Resurrecting extinct animals?
- NOT!!
37Violation of Human Dignity
- Distinctions between man and animals
- Child becomes a thing to be designed, sold and
marketed
38Human Experimentation
- No matter how much animal experimentation is
done, human embryos will be sacrificed
39Cloned Expectations
- People cloned for certain traits will have high
expectations - Clones are identical twins, not parent and child
40Summary
- Tremendous waste of human life at embryonic
stages. - Degradation of human dignity - humans
designed/created for purposes other than
procreation. - Dangerous family situations
- Unwise personal expectations
- Beneficial research goals achievable by other
means.
41The drive toward human cloning is being powered
by a selfish mythical right to total reproductive
freedom and further fueled by a profound lack of
moral courage on the part of science and society.
We are unwilling to say that there are some
experiments we will not perform.
42Biblical Clones?
- Rebecca a thirtysomething San Francisco Bay
Area resident, spent seven years trying to
conceive a child with her husband. Having been
to hell and back with IVF treatment, Rebecca is
now as thoroughly committed to cloning as she is
to Christianity. Its in the Bible be fruitful
and multiply, she says.
43Biblical Clones?
- People say, Youre playing God. But were not.
Were using the raw materials the good Lord gave
us. What does the doctor do when the heart has
stopped? They have to do direct massage of the
heart. You could say the doctor is playing God.
But we save a life. With human cloning, were not
so much saving a life as creating a new being by
manipulation of the raw materials, DNA, the
blueprint of life. Youre simply using it in a
more creative manner.
44Questions about Cloning
- Will Clones be unique individuals?
- Does a clone have to start as a baby?
- Will cloning affect genetic diversity?
- Can homosexuals use cloning to have children?
- Will clones have a soul?
