Are human genes the same as human destiny' Could natural selection
be skewed so far that we had a nation of carbon-copy people' These are
some of the weird science' fears voiced not only by opponents of cloning,
but as cautions by proponents. But it is unlikely that such an event would
There are, in fact, four different types of cloning. Two, gene
cloning and cellular cloning, are merely methods of increasing supplies of
DNA or of various cells to facilitate experiments and have nothing whatever
to do with the much-feared whole organism cloning. (Shannon, 111)
A third form of cloning is called embryo division and is artificially
dividing an embryo in order to create multiple copies, and is used in the
livestock industry regularly; whether it contributes to Mad Cow disease is
another investigation entirely, although certainly there is some ethical
content involved in the existence of Mad Cow disease and containing its
spread. (Shannon, 111) Embryo division might be described as an
artificial way to produce identical twins, as it mimics what happens in
that very natural occurrence. From a technological standpoint, cloning is
simply an extension of existing methods of assisting reproduction and
determining genetic makeup of offspring, cow, human or otherwise. (Kass and
The fourth sort of cloning is the one most people think about, the
"Dolly the Sheep" sort of cloning. This is known scientifically as somatic
cell nuclear transfer, or whole organism cloning. In this, the nucleus of
the egg is removed and placed with the nucleus of another cell, which
creates an identical genetic copy of the donor of that nucleus. "What is
of utmost importance in the Dolly experiment is demonstrating that the
genetic material in fully differentiated adult cells can be reactivated to
generate a whole new being." (Shannon, 111) And that is what has caused
all the...
