A new life begins when
a male sperm and a female egg join. This new life has in it
some chromosomes
from the father and some from the mother. So it will inherit
some characteristics from each parent. It is, if you like,
a mix of both parents. Everyone knows this is
true of all human life.
But here comes the shock.
Now, we are told, human life can start in another way. A way
that does not need to join a male
sperm and a female egg. This new way of reproduction is called
cloning.
This is
how it works. Each single cell
in the human body has in it a full set of chromosomes. All
the genetic
information that a living thing needs is in those chromosomes
in the nucleus
of the cell. So if any body cell can be made to divide and
grow, it can form a new life. Since this new life would have
only one set of chromosomes, it would be an exact replica
of the body it comes from. This type of cloning has worked
with plants, fruit flies, and even frogs.
As far back as 1968 a
man, J.
B. Gurdon from Oxford University, produced a cloned
frog.
Could this procedure work
with people? Scientists say it could. And it would work in
much the same way. A healthy egg would be taken from a woman's
body. No male sperm would fertilize
it. The nucleus of the egg would be destroyed. It would be
replaced with the nucleus of a new cell taken from the arm
or anywhere else on the body of the donor. This donor could
be a man or woman. The egg would then be put back into the
womb
of the woman. The egg would grow into a new life even though
no sperm had fertilized it.
The new baby would have
only one parent. The parent would not have to be the woman
in whose womb it grew. The parent would be the donor from
whom the new nucleus had come, because it would be that person's
chromosomes in the new baby. And the baby would be an exact
twin of the donor.
Cloning means that anyone
could have a child. It would give new hope to people who cannot
have a baby in the usual way. All you have to do is have one
cell taken from anywhere on your body. Then, the nucleus of
that cell would be put in the place of the nucleus of an egg
cell and allowed to grow in a womb, or perhaps in a test tube.
A new life would be made that would be a twin of the donor.
Scientists are still at
work to see if they can make this new way of reproduction
perfect.
But the thought of cloning
brings all sorts of questions and fears. The use of cloning
could change our world to the point where we might not know
it. The family, as it is now, would not exist. Sex would not
be needed for reproduction. The whole meaning of "parent"
would change. We might even end
up with whole tribes
of people who look exactly
alike.
"Clone clans"
might take
the place of nations and races.
It is easy to see how
cloning could be misused.
One nation could set
out to make a master race of cruel "Hitlers"
who would all be exactly alike and who would kill or make
slaves of everyone else in the world.
What about crime? Think
what would happen if all the murderers,
thieves, cheats,
and swindlers
in the world made thousands of clones of themselves to run
the greatest crime ring in the history of the world.
What about things that
go
wrong? What
if — by
accident — we got a race of hideous
monsters
that would make clones of themselves forever and ruin the
world? Scientists cannot promise that such things might not
happen.
There is also the moral
side of the issue. Is it right for humans to change the way
life begins? Or is God the only one who can do that?
Of course, there is a
bright side. Think of all the great people in the world who
could clone themselves so their genius could last forever.
The world could keep all its great athletes, writers, engineers,
scientists, and scholars. There could be a constant supply
of all the good and useful people the world could need.
There are many things
to consider about clones. But the fact remains. Whether you
think it is right or wrong, it can be done. It has already
been done with animals. Is there any reason why it should
not be tried with humans?
