Human Cloning Isn’t as Scary as It Sounds
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
about the possibility of cloning humans. For the most part, however, the ethical
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
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
the genetic contribution to the traits we value most deeply, from intelligence
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 obtain a successful sheep clone. While cloning
methods may improve, we should note that even standard IVF techniques typically
have a success rate of less than 20 percent.) So why would anyone go to the
trouble of cloning?
There are, of course, a few reasons people might go to the trouble, and so it’s
worth pondering what they think they might accomplish, and what sort of ethical
quandaries they might engender. Consider the hypothetical example of the couple
who wants to replace a child who has died. The couple doesn’t seek to have
another child the ordinary way because they feel that cloning would enable them
would be producing an entirely different person, a delayed identical twin of
that child. Once they understood that, it is unlikely they would persist.
But suppose they were to persist? Of course we can’t deny that possibility. But
a couple so persistent in refusing to acknowledge the genetic facts is not
likely to be daunted by ethical considerations or legal restrictions either. If
we have a great deal more than cloning to worry about.
Another disturbing possibility is the person who wants a clone in order to have
acceptable “spare parts” in case he or she needs an organ transplant later in
life. But regardless of the reason that someone has a clone produced, the result
accompany that status. It truly would be a disaster if the results of human
cloning were seen as less than fully human. But there is certainly no moral
justification for and little social danger of that happening; after all, we do
not accord lesser status to children who have been created through IVF or embryo
There are other possibilities we could spin out. Suppose a couple wants a
“designer child”?a clone of Cindy Crawford or Elizabeth Taylor?because they want
someone wants a clone, never mind of whom, simply to enjoy the notoriety of
having one. We cannot rule out such cases as impossible. Some people produce
children for all sorts of frivolous or contemptible reasons. But we must
remember that cloning is not as easy as going to a video store or as engaging as
that cloning would involve, it is likely that such cases would be exceedingly
placing a legal barrier in the path of those with desires perverse enough or
delusions recalcitrant enough to seek cloning despite its limited potential and
formidable costs? For one thing, these are just the people that a legal ban
would be least likely to deter. But more important, a legal barrier might well
make cloning appear more promising than it is to a much larger group of people.
If there were significant interest in applying this technology to human beings,
it would indicate a failure to educate people that genetic determinism is
profoundly mistaken. Under those circumstances as well, however, a ban on human
cloning would not only be ineffective but also most likely counterproductive.
Ineffective because, as others have pointed out, the technology does not seem to
require sophisticated and highly visible laboratory facilities; cloning could
easily go underground. Counterproductive because a ban might encourage people to
believe that there is a scientific basis for some of the popular fears
associated with human cloning?that there is something to genetic determinism
There is a consensus among both geneticists and those writing on ethical, legal
and social aspects of genetic research, that genetic determinism is not only
eugenic programs premised on the belief that what we value in people is entirely
dependent on their genetic endowment or the color of their skin. Though most
that genes contain a person’s destiny. It would be unfortunate if, by treating
cloning as a terribly dangerous technology, we encouraged this cultural myth,
We should remember that most of us believe people should be allowed to decide
with whom to reproduce, when to reproduce and how many children they should have.
when she has children?or even how many. Why, then, would we object if a woman
decides to give birth to a child who is, in effect, a non-contemporaneous
identical twin of someone else?
By arguing against a ban, I am not claiming that there are no serious ethical
concerns to the manipulation of human genes. Indeed there are. For example, if
it turned out that certain desirable traits regarding intellectual abilities or
character could be realized through the manipulation of human genes, which of
these enhancements, if any, should be available? But such questions are about
method of trait selection: It simply takes a pre-existing, unengineered genetic
combination of traits and replicates it.
I do not wish to dismiss the ethical concerns people have raised regarding the
broad range of assisted reproductive technologies. But we should acknowledge
that those concerns will not be resolved by any determination we make regarding
the specific acceptability of cloning.
