1、Severino Antinori is a rich Italian doctor with a string of private fertility clinics to his name.He likes watching football and claims the Catholic faith.Yet the Vatican is no fan of his science.In his clinics,Antinori alreadyoffers every IVF treatment under the Sun,but still there are couples he c

2、annot help.So now the man Italians call Dr Miracle is offering to clone his patients to create the babies they so desperately want.And of course its created quite a stir,with other scientists rounding on Antinori as religious leaders line up to attack his cloning plan as an insult to human dignity.Y

3、et its an ambition Antinori has expressed many times before.Whats new is that finally it seems to be building a head of steam.Like-minded scientists from the US have joined Antinori in his cloning adventure.At a conference in Rome last week they claimed hundreds of couples have already volunteered f

4、or the experiments.Antinori shot to fame seven years ago helping grandmothers give birth using donor eggs.Later he pioneered the use of mice to nurture the sperm of men with poor fertility.He is clearly no ordinary scientist but a showman who thrives on controversy and pushing reproductive biology t

5、o the limits.And that of course is one reason why hes seen as being so dangerous.However,his idea of using cloning to combat infertility is not as mad as it sounds.Many people have a hard job seeing the point of reproductive cloning.But for some couples,cloning represents the only hope of having a c

6、hild carrying their genes,and scientists like Antinori are probably right to say that much of our opposition to cloning as a fertility treatment is irrational.In future we may want to change our minds and allow it in special circumstances.But only when the science is ready.And thats the real problem

7、.Five years on from Dolly,the science of cloning is still stuck in the dark ages.The failure rate is a shocking 97 per cent and deformed babies all too common.Even when cloning works,nobody understands why.So forget the complex moral arguments.To begin cloning people now,before even the most basic q

8、uestions have been answered,is simply a waste of time and energy.This is not to say that Antinori will fail,only that if he succeeds it is likely to be at an unacceptably high price.Hundreds of eggs and embryos will be wasted and lots of women will gothrough difficult pregnancies resulting in miscar

9、riages or abortions.A few years from now techniques will have improved and the wasteful loss wont be as excessive.But right now there seems to be little anyone can do to keep the cloners at bay.And its not just Antinori and his team who are eager to go.A religious group called the Raelians believes

10、cloning is the key to achieving immortality,and it,too,claims to have the necessary egg donors and volunteers willing to be implanted with cloned embryos.So what about tougher laws?Implanting cloned human embryos is already illegal in many countries but it will never be prohibited everywhere.In any

11、case,the prohibition of cloning is more likely to drive it underground than stamp it out.Secrecy is already a problem.Antinori and his team are refusing to name the country theyll be using as their base.Like it or not,the research is going ahead.Sooner or later we are going to have to decide whether

12、 regulation is safer than prohibition.Antinori would go for regulation,of course.He believes it is only a matter of time before we lose our hang-ups about reproductive cloning and accept it as just another IVF technique.Once the first baby is born and it cries,he said last week,the world will embrac

13、e it.But the world will never embrace the first cloned baby if it is unhealthy or deformed or the sole survivor of hundreds of pregnancies.In jumping the gun,Dr Miracle and his colleagues are taking one hell of a risk.If their instincts are wrong,the backlash against cloning and indeed science as a whole could be catastrophic.(704 words)v.形成；组成形成；组成v.形状；形式形状；形式n.v.改革改革n.v.转换转换
