At the cusp of dot-com frenzy and the biotech century, a group
of influential scientists and pundits has begun zealously promoting
a new bio-engineered utopia. In the world of their visionary fervor,
parents will strive to afford the latest genetic "improvements"
for their children. According to the advocates of this human future
(or, as some term it, "post-human" future), the exercise
of consumer preferences for offspring options will be the prelude
to a grand achievement: the technological control of human evolution.
My first close encounter with this techno-eugenic enthusiasm
was in a 1997 book written for an unconverted lay audience by
Princeton geneticist Lee M. Silver. In Remaking Eden: Cloning
and Beyond in a Brave New World (New York: Avon Books 1998),
Silver spins out scenarios of a future in which affluent parents
are as likely to arrange genetic enhancements for their children
as to send them to private school.
Silver confidently predicts that upscale baby-making will soon
take place in fertility clinics, where prospective parents will
undergo an IVF procedure to create an embryo, then select the
physical, cognitive, and behavioral traits they desire for their
child-to-be. Technicians will insert the genes said to produce
those traits into the embryo, and implant the embryo in the
mother's womb. Nine months later, a designer baby will be born.
After a few centuries of these practices, Silver believes, humanity
will bifurcate into genetic ubermenschen and untermenschen—and
not long thereafter into different species. Here is Silver's
prediction for the year 2350:
| |
The GenRich—who account for 10 percent
of the American population—all carry synthetic genes.
Genes that were created in the laboratory….The GenRich
are a modern-day hereditary class of genetic aristocrats….All
aspects of the economy, the media, the entertainment industry,
and the knowledge industry are controlled by members of
the GenRich class. |
|
How do the other 90 percent live? Silver is quite blunt on
this point as well: "Naturals work as low-paid service
providers or as laborers." That rich and poor already live
in biologically disparate worlds can be argued on the basis
of any number of statistical measures: life expectancy, infant
mortality, access to health care. Of course, medical resources
and social priorities could be assigned to narrowing those gaps.
But if Silver and his cohort of designer-baby advocates have
their way, precious medical talent and funds will be devoted
instead to a technically dubious project whose success will
be measured by the extent to which it can inscribe inequality
onto the human genome. Silver pushes his vision still further:
| |
[A]s time passes,...the GenRich class and
the Natural class will become the GenRich humans and the
Natural humans—entirely separate species with no ability
to cross-breed, and with as much romantic interest in each
other as a current human would have for a chimpanzee. |
|
Silver understands that such scenarios are disconcerting. He
counsels realism. In other words, he celebrates the free reign
of the market and perpetuates the myth that private choices
have no public consequences:
| |
Anyone who accepts the right of affluent
parents to provide their children with an expensive private
school education cannot use 'unfairness' as a reason for
rejecting the use of reprogenetic technologies….There
is no doubt about it…whether we like it or not, the
global marketplace will reign supreme. |

When I first read Silver's book, I imagined that these sorts
of bizarre prognostications must be the musings of a lab researcher
indulging in mad-scientist mode. I soon learned differently.
They are not ravings from the margins of modern science, but
emanations from its prestigious and respected core. Silver vividly
and accurately represents a technical and political agenda for
the human future that is shared by a disturbing number of Nobel
laureate scientists, biotech entrepreneurs, social theorists,
bioethicists, and journalists.
Since the late 1990s, this loose alliance has been publicly
and energetically promoting the genetic technology known as
"human germline engineering"— modifying the genes
passed to our children by manipulating embryos at their earliest
stages of development. Such genetic modifications would be replicated
in all subsequent generations, providing supporters with the
basis to claim that "we" are on the brink of "seizing
control of human evolution." Frank about their commitments
to control and "enhancement," advocates of human germline
engineering claim that the voluntary parental participation
they foresee refutes any characterization of their project as
"eugenic." With public conferences, popular books,
scholarly articles, websites, and mainstream media appearances,
they are waging an all-out campaign to win public acceptance
of their techno-eugenic vision.
The promoters of a designer-baby future believe that the new
human genetic and reproductive technologies are both inevitable
and a boon to humanity. They exuberantly describe near-term
genetic manipulations—within a generation—that may increase
resistance to diseases, "optimize" height and weight,
and boost intelligence. Further off, but within the lifetimes
of today's children, they foresee the ability to adjust personality,
design new body forms, extend life expectancy, and endow hyper-intelligence.
Some even predict splicing traits from other species into children:
In late 1999, for example, an ABC Nightline special on human
cloning speculated that genetic engineers would learn to design
children with "night vision from an owl" and "supersensitive
hearing cloned from a dog."
How plausible are such scenarios? Because human beings are
far more than the product of genes—because DNA is one of many
factors in human development—the feats of genetic manipulation
eventually accomplished will almost certainly turn out to be
much more modest than what the designer-baby advocates predict.
But we cannot dismiss the possibility that scientists will achieve
enough mastery over the human genome to wreak enormous damage—biologically
and politically.
Promoting a future of genetically engineered inequality legitimizes
the vast existing injustices that are socially arranged and
enforced. Marketing the ability to specify our children's appearance
and abilities encourages a grotesque consumerist mentality toward
children and all human life. Fostering the notion that only
a "perfect baby" is worthy of life threatens our solidarity
with and support for people with disabilities, and perpetuates
standards of perfection set by a market system that caters to
political, economic, and cultural elites. Channeling hopes for
human betterment into preoccupation with genetic fixes shrinks
our already withered commitments to improving social conditions
and enriching cultural and community life.
Germline engineering is now common in laboratory animals, though
it remains at best an imprecise technology, requiring hundreds
of attempts before a viable engineered animal is produced. Human
germline manipulation has not been attempted: The only kind
of human genetic procedures currently practiced involve efforts
to "fix" or substitute for the genes of somatic (body)
cells in people with health problems that in some way reflect
the functions of genes.
In about five hundred "gene therapy" clinical trials
since the early 1990s, doctors have tried to introduce genetic
modifications to patients' lungs, nerves, muscles, and other
tissues. These efforts have been largely unsuccessful. In late
1999, their safety was also called starkly into question by
the death of an 18-year-old enrolled in a clinical trial, and
by ensuing revelations of almost 700 other "serious adverse
effects" that researchers and doctors had somehow failed
to report to the proper regulatory authorities. Some observers
have commented that gene therapy would more accurately be called
"genetic experiments on human subjects."
Many people are reluctant to oppose human germline engineering
because they believe that "genetics" will deliver
medical cures or treatments. But there is no reason that we
cannot forgo germline engineering and still support other genetic
technologies that do in fact hold promising medical potential.
In fact, the medical justifications for human germline engineering
are strained, while its ethical and political risks are profound.
Fortunately, the distinction between human germline engineering
and other genetic technologies (including somatic genetic engineering)
is a reasonably clear technical demarcation. In many countries,
this demarcation is being drawn as law. Legislation that would
ban human germline engineering and reproductive cloning is making
its way through the Canadian parliament. Germany's Embryo Protection
Act of 1990 makes human cloning and germline engineering criminal
acts, and the Japanese legislature is considering establishing
prison terms for human cloning. A number of other European countries
forbid cloning and germline engineering indirectly by outlawing
non-therapeutic research on human embryos. Twenty-two European
countries have signed a Council of Europe bioethics convention
that includes similar restrictions. In the United States, however,
neither federal law nor policy forbids human germline engineering
or cloning, though federal funds cannot be used for any kinds
of human
cloning experiments.
In order to bring the new human genetic technologies under
social governance, strong political pressure and a broad social
movement will be necessary. Though no such movement currently
exists, efforts to alert and engage a variety of constituencies
are getting underway.
The movement that this work aims to catalyze will need to draw
in a wide range of constituencies, and encompass a variety of
motivations. Some participants will base their opposition to
a techno-eugenic future on their commitments to equality and
justice, and to human improvement through social change rather
than technical fix. Others will be moved by the threats to human
dignity and human rights, and the horror of treating children
as custom-made commodities, that germline engineering and cloning
entail. Still others will find their primary inspiration in
the precautionary principle, or their wariness of techno-scientific
hubris and a reductionist world view, or their objections to
corporate ownership of life at the molecular level, or their
skepticism about the drastic technological manipulation of the
natural world.
It will be far easier to prevent a techno-eugenic future if
we act before human germline manipulation develops further,
either as technology or ideology. This is a crucial juncture:
a window that the campaign for human germline engineering is
trying to slam shut. Your participation is urgently needed.
