This gift is made even more profound by the fact that we ourselves are not only its recipients but also its conduits: we receive life and we help create it. But our participation in the creation of life must never be misconstrued as control. Rather, we must be humbled by the power of the life force at the moment of conception. The idea of “outsourcing” the creation of human life, of relegating it to a laboratory, of reducing the anticipation of childbirth to a trip to the mall or a selection from a catalog, leaves us with a profoundly hollow feeling. The mys- tery is replaced by design; the surrender to nature is replaced by arrogant control. Should we turn our noses up at one who would offer us the most precious gift in the universe, only to say: “Sorry, but I think I can do better?” Cloning is the engineering of human life. We have for the first time the ability to determine the exact genetic makeup of a human being, to thwart the essential random (or seemingly ran- dom) processes that form the basis of natural selection, to employ unnatural selection. A child can be created that is no longer a unique cre- ation but the end product of an assembly line, with carefully designed and tested features. Are the astonishing products of natural selection that we find around us somehow deficient? Are we so full of hubris 1 as to think we have a better way than nature or God? If human cloning becomes acceptable, we will have created a new society in which the essence of human life is marginalized. Industries will arise that turn human procreation into a prof- itable free-market enterprise. The executive boards of these companies, rather than nature or God, will decide the course of human evolution, with more concern for quarterly profit reports than for the fate of humanity. 5.

Answer the questions on the basis of what is stated or implied in the passage and in any introductory material that may be provided. Questions 7–19 are based on the following passages. Since 1996, when scientists at the Roslin Insti- tute in England cloned a sheep from the cells of another adult sheep, many inside and outside the scientific community have debated the ethics of cloning the cells of human beings. The following passages are excerpts of arguments on this issue. PASSAGE 1 With the specter of human cloning looming on the horizon, the dominant ethical question is: what is a human being? Until now, our respect for human life has rested fundamentally on the 1 Excessive pride or arrogance 5 10 15 20 25 30 35 40 45 Line 8 8 888 8 GO ON TO THE NEXT PAGE These are not idle concerns. Even as we pon- der the ethical implications of human cloning, companies are forging ahead with the cloning of human stem cells for seemingly beneficial purposes, marching steadily toward a Brave New World 2 in which humanity will be forever different from what it is today. PASSAGE 2 The irrational fears about human cloning that abound from all parts of the political spectrum should not surprise anyone who knows a little bit about the history of technology. Hardly anything significant has been invented that no segment of the population has denounced as evil: factories, trains, automobiles, telephones, televisions, computers. Not even medicine has been spared this vituperation, despite its obvi- ous benefits to humanity. Before the merits of surgery became obvious, it was unimaginable that slicing the flesh of a human being could do more harm than good. At first glance, it might seem that cloning is a whole new ballgame. After all, cloning is “the en- gineering of human life,” isn’t it? It is the mass production of designer babies. It is the end of evolution, or at least the beginning of its corpo- rate management. It is certainly a slap in the face of God. Or is it? One of scariest things to the opponents of cloning is the prospect of human beings having identical genetic codes. As cloning foe Jeremy Rifkin has said: “It’s a horrendous crime to make a Xerox of someone. You’re putting a human into a genetic straitjacket.” Logically, then, Mr. Rifkin must be repulsed by natural- born identical multiples: there is no scientific way to distinguish the DNA of one’s identical twin from that of one’s clone. Perhaps the whole system of natural human procreation is sus- pect, if it is capable of occasionally churning out such monstrosities. We need nothing more than the most rudi- mentary common sense to see how vacuous such an argument is. We all know identical twins who have their own unique thoughts, talents, experiences, and beliefs. They are not horrendous monsters. Human beings are more than merely their DNA; they are the products of the continual and inscrutably complex inter- actions of environment and biology. Human clones would be no different. The most common objection we hear from the anti-cloning lobby is that those who would clone human beings are “playing God,” and trespassing into territory that can only bring the wrath of nature or its creator. Most of these arguments are basically theological, and rest on the most effective tool of human control ever in- vented: fear of God. We can easily get people to hate something by calling it “unnatural.” But this argument is even more easily demolished than the previous one, because it falls so easily in line with so many obviously silly claims. This argument rests on the assumption that human ingenuity has essentially no value, that improv- ing on nature is the height of hubris. This is the reasoning of the Dark Ages. Nature presents veg- etables and meats only in raw form, so isn’t the cooking of food a human transgression against nature? Nature gives us feet, not wheels, so aren’t bicycles evil? If we were to abandon all of the “unnatural” practices and products from our lives, we would be shivering in caves eating uncooked leaves and bugs. Maybe human procreation is a different arena, however, more sacred than all of the others. But then, why have the technologies of fertility enhancement, in vitro fertilization, embryo transfer, and birth control become so widely accepted? They are telling examples: each of these procreational technologies had legions of vocal opponents—at first—but over time the protests mellowed as people realized that the sky wouldn’t fall after all. Familiarity dissipates fear. What most opponents of genetic technology don’t realize is that their supposedly “moral” objections are impeding true moral progress. With genetic engineering and stem cell research, scientists finally have within their grasp tech- nologies that can produce ample food for a starving world and cure devastating illnesses. Only ignorant superstition stands in their way. 56 McGRAW-HILL’S SAT 2 A futuristic novel by Aldous Huxley that describes the mass pro- duction of genetically identical human babies 50 55 60 65 70 75 80 85 90 95 100 105 110 115 120 125 130 135 CHAPTER 2 / DIAGNOSTIC SAT 57 8 8 888 8 GO ON TO THE NEXT PAGE 7.
