Baby, It's You! And You, And You...

Before we assume that the market for human clones consists mainly of narcissists who think the world deserves more of them or neo-Nazis who dream of cloning Hitler or crackpots and mavericks and mischief makers of all kinds, it is worth taking a tour of the marketplace. We might just meet ourselves there.

Imagine for a moment that your daughter needs a bone-marrow transplant and no one can provide a match; that your wife's early menopause has made her infertile; or that your five-year-old has drowned in a lake and your grief has made it impossible to get your mind around the fact that he is gone forever. Would the news then really be so easy to dismiss that around the world, there are scientists in labs pressing ahead with plans to duplicate a human being, deploying the same technology that allowed Scottish scientists to clone Dolly the sheep four years ago?

All it took was that first headline about the astonishing ewe, and fertility experts began to hear the questions every day. Our two-year-old daughter died in a car crash; we saved a lock of her hair in a baby book. Can you clone her? Why does the law allow people more freedom to destroy fetuses than to create them? My husband had cancer and is sterile. Can you help us?

The inquiries are pouring in because some scientists are ever more willing to say yes, perhaps we can. Last month a well-known infertility specialist, Panayiotis Zavos of the University of Kentucky, announced that he and Italian researcher Severino Antinori, the man who almost seven years ago helped a 62-year-old woman give birth using donor eggs, were forming a consortium to produce the first human clone. Researchers in South Korea claim they have already created a cloned human embryo, though they destroyed it rather than implanting it in a surrogate mother to develop. Recent cover stories in Wired and the New York Times Magazine tracked the efforts of the Raelians, a religious group committed to, among other things, welcoming the first extraterrestrials when they appear. They intend to clone the cells of a dead 10-month-old boy whose devastated parents hope, in effect, to bring him back to life as a newborn. The Raelians say they have the lab and the scientists, and--most important, considering the amount of trial and error involved--they say they have 50 women lined up to act as surrogates to carry a cloned baby to term.

Given what researchers have learned since Dolly, no one thinks the mechanics of cloning are very hard: take a donor egg, suck out the nucleus, and hence the DNA, and fuse it with, say, a skin cell from the human being copied. Then, with the help of an electrical current, the reconstituted cell should begin growing into a genetic duplicate. "It's inevitable that someone will try and someone will succeed," predicts Delores Lamb, an infertility expert at Baylor University. The consensus among biotechnology specialists is that within a few years--some scientists believe a few months--the news will break of the birth of the first human clone.

At that moment, at least two things will happen--one private, one public. The meaning of what it is to be human--which until now has involved, at the very least, the mysterious melding of two different people's DNA--will shift forever, along with our understanding of the relationship between parents and children, means and ends, ends and beginnings. And as a result, the conversation that has occupied scientists and ethicists for years, about how much man should mess with nature when it comes to reproduction, will drop onto every kitchen table, every pulpit, every politician's desk. Our fierce national debate over issues like abortion and euthanasia will seem tame and transparent compared with the questions that human cloning raises.

That has many scientists scared to death. Because even if all these headlines are hype and we are actually far away from seeing the first human clone, the very fact that at this moment, the research is proceeding underground, unaccountable, poses a real threat. The risk lies not just with potential babies born deformed, as many animal clones are; not just with desperate couples and cancer patients and other potential "clients" whose hopes may be raised and hearts broken and life savings wiped out. The immediate risk is that a backlash against renegade science might strike at responsible science as well.

The more scared people are of some of this research, scientists worry, the less likely they are to tolerate any of it. Yet variations on cloning technology are already used in biotechnology labs all across the country. It is these techniques that will allow, among other things, the creation of cloned herds of sheep and cows that produce medicines in their milk. Researchers also hope that one day, the ability to clone adult human cells will make it possible to "grow" new hearts and livers and nerve cells.

But some of the same techniques could also be used to grow a baby. Trying to block one line of research could impede another and so reduce the chances of finding cures for ailments such as Alzheimer's and Parkinson's, cancer and heart disease. Were some shocking breakthrough in human cloning to cause "an overcompensatory response by legislators," says Rockefeller University cloning expert Tony Perry, "that could be disastrous. At some point, it will potentially cost lives." So we are left with choices and trade-offs and a need to think through whether it is this technology that alarms us or just certain ways of using it.
