【正文】 M team has produced only a dozen or so embryos (胚胎) carrying Missy’s DNA. None have survived the transfer to a surrogate (代孕的) mother. The wastage of eggs and the many spontaneously aborted fetuses (胎) may be acceptable when you’re dealing with cats or bulls, he argues, but not with humans. “Cloning is incredibly inefficient, and also dangerous,” he says.Even so, dog cloning is a mercial opportunity, with a nice research payoff. Ever since Dolly the sheep was cloned in 1997, Westhusin’s phone has been ringing with people calling in hopes of duplicating their cats and dogs, cattle and horses. “A lot of people want to clone pets, especially if the price is right,” says Westhusin. Cost is no obstacle for Missy’s mysterious billionaire owner。 he’s put up $ million so far to fund Aamp。M University. “It’s a stupid endeavor.” That’s an interesting choice of adjective, ing from a man who has spent millions of dollars trying to clone a 13yearold dog named Missy. So far, he and his team have not succeeded, though they have cloned two cows and expect to clone a cat soon. They just might succeed in cloning Missy this spring—or perhaps not for another 5 years. It seems the reproductive system of man’s best friend is one of the mysteries of modern science.Westhusin’s experience with cloning animals leaves him upset by all this talk of human cloning. In three years of work on the Missy project, using hundreds upon hundreds of dog’s eggs, the Aamp。M’s research.Contrary to some media reports, Missy is not dead. The owner wants a twin to carry on Missy’s fine qualities after she does die. The prototype is, by all accounts, athletic, goodnatured and supersmart. Missy’s master does not expect an exact copy of her. He knows her clone may not have her temperament. In a statement of purpose, Missy’s owner and the Aamp。 both yielded to the normal wearing out of the body after a long and full life. Their homes happened to be near each other, so I paid condolence (吊唁) calls on the two families on the same afternoon.At the first home, the son of the deceased (已故的) woman said to me, “If only I had sent my mother to Florida and gotten her out of this cold and snow, she would be alive today. It’s my fault that she died.” At the second home, the son of the other deceased woman said, “If only I hadn’t insisted on my mother’s going to Florida, she would be alive today. That long airplane ride, the abrupt change of climate, was more than she could take. It’s my fault that she’s dead.”When things don’t turn out as we would like them to, it is very tempting to assume that had we done things differently, the story would have had a happier ending. Priests know that any time there is a death, the survivors will feel guilty. Because the course of action they took turned out badly, they believe that the opposite coursekeeping Mother at home, postponing the operation—would have turned out better. After all, how could it have turned out any worse?There seem to be two elements involved in our readiness to feel guilt. The first is our pressing need to believe that the world makes sense, that there is a cause for every effect and a reason for everything that happens. That leads us to find patterns and connections both where they really exist and where they exist only in our minds.The second element is the notion that we are the cause of what happens, especially the bad things that happen. It seems to be a short step from believing that every event has a cause to believing that every disaster is our fault. The roots of this feeling may lie in our childhood. Psychologists speak of the infantile myth of omnipotence (萬(wàn)能). A baby es to think that the world exists to meet his needs, and that he makes everything happen in it. He wakes up in the morning and summons the rest of the world to its tasks. He cries, and someone es to attend to him. When he is hungry, people feed him, and when he is wet, people change him. Very often, we do not pletely outgrow that infantile notion that our wishes cause things to happen.26.

It could also lead to the cloning of special rescue dogs and many endangered animals.However, Westhusin is cautious about his work. He knows that even if he gets a dog pregnant, the off
