The Issue of Human Cloning

         The recent news of the successful cloning of an adult sheep-in
which the sheep's DNA was inserted into an unfertilized sheep egg to
produce a lamb with identical DNA-has generated an outpouring of
ethical concerns. These concerns are not about Dolly, the now famous
sheep, nor even about the considerable impact cloning may have on the
animal breeding industry, but rather about the possibility of cloning
humans. For the most part, however, the ethical concerns being raised
are exaggerated and misplaced, because they are based on erroneous
views about what genes are and what they can do. The danger,
therefore, lies not in the power of the technology, but in the
misunderstanding of its significance.

         Producing a clone of a human being would not amount to
creating a "carbon copy"-an automaton of the sort familiar from
science fiction. It would be more like producing a delayed identical
twin. And just as identical twins are two separate
people-biologically, psychologically, morally and legally, though not
genetically-so a clone is a separate person from his or her
non-contemporaneous twin. To think otherwise is to embrace a belief in
genetic determinism-the view that genes determine everything about us,
and that environmental factors or the random events in human
development are utterly insignificant. The overwhelming consensus
among geneticists is that genetic determinism is false.

         As geneticists have come to understand the ways in which genes
operate, they have also become aware of the myriad ways in which the
environment affects their "expression." The genetic contribution to
the simplest physical traits, such as height and hair color, is
significantly mediated by environmental factors. And the genetic
contribution to the traits we value most deeply, from intelligence to
compassion, is conceded by even the most enthusiastic genetic
researchers to be limited and indirect. Indeed, we need only appeal to
our ordinary experience with identical twins-that they are different
people despite their similarities-to appreciate that genetic
determinism is false.

         Furthermore, because of the extra steps involved, cloning will
probably always be riskier-that is, less likely to result in a live
birth-than in vitro fertilization (IVF) and embryo transfer. (It took
more than 275 attempts before the researchers were able to...
