Doctors Panayiotis Zavos and Severino Antinori claim they are ready to embark on the greatest human experiment of our age. They say they will attempt to clone a human being before the year is out. Most people think the objections to this are ethical - human cloning would create many moral dilemmas.

There is another question that few ever ask: is the science actually ready yet for cloning healthy humans? Horizon follows the latest research, which has led many scientists to believe that Zavos and Antinori's plans to clone the first human could end in tragedy. The programme also meets couples like Matthew and Desirée Racquer (above) who think cloning offers them the only way to raise a child who is truly their own.


For decades, cloning remained within the realms of science fiction. The idea that instead of combining a sperm and an egg, a new human could be made from a single cell taken from an adult, seemed completely absurd. But that all changed in February 1997, when the Roslin Institute (right) introduced the world to Dolly the sheep - the first animal cloned from an adult. Ever since Dolly, scientists have been continuing to experiment with cloning animals. So far, they have succeeded in cloning sheep, cattle, pigs, goats and mice, fuelling the belief that humans could be next.

An unreliable procedure

But even Dolly's creator, Professor Ian Wilmut, is concerned that beneath the veneer of success lies a disturbing reality. Most cloning attempts on animals so far have resulted in failed implantation or abnormal foetuses. Of the animals born alive, some soon die of catastrophic organ failure. Others appear to be healthy for weeks or even months, then die suddenly, sometimes from bizarre new illnesses which do not occur in nature.

Years of painstaking work are only now revealing some vital clues to what is going wrong. Horizon talks to the scientists who have uncovered new evidence, suggesting that the process of cloning itself causes subtle errors in the way genes function. These random errors may be like a timebomb inside every clone, causing some of the strange - often fatal - problems. There's no reason to think cloned human babies would fare any better. According to embryologist Dr Susan Avery, death might be the best outcome for many human clones. If they survived, they would suffer from catastrophic illnesses that modern medicine is powerless to prevent or cure.

Test tube troubles

Dr Zavos claims that these problems are the result of the still unsophisticated methods being used by animal researchers. Using advanced in vitro fertilisation ('test tube baby') techniques, he claims that he will strive to make human cloning safer than natural reproduction. Now though, it seems that some IVF procedures themselves are being investigated for possible harmful effects on the long term health of children. Professor Gerald Schatten of the University of Pittsburgh reveals evidence of these risks, which could be magnified in cloning.

Most reproductive specialists believe that the danger to any human born by cloning is enormous. But the would-be human cloners are determined to clone a human baby. If they proceed, they may be courting tragedy.

  • this is unessasary i see why somone would want to do it but this guy just wants to do this for fame not for anyother reason but fame

  • @ExtraWideSeal  I was gonna say te same thing

  • Has this man succeeded yet? Did he create a clone?

  • lol i dont think it will be nice, when you wake up in the middle of the night and your clone is staring at you !! just saying it's freaky.

  • @2007words

    cloning of human beings, however if you would watch the whole show before you judge, and take a minute to step into their shoes as I did, I'm sure you would at least some what see their way of thinking.

    Yeah your little speech was cute and all, but the couple DID say they were infertile. The wife had cancer a few years previous and it has left her with the inability to bear children. It also said that they DID try to adopt. They were all ready with the papers and everything, which, trust me, is a long and grueling process, when for whatever reason, they were denied their child. The cloning thing is one of the only chances for a child they have left. I'm not saying I condone the clo

  • i was looking for a cloned human...... :-/

  • Will to be fun to get your own slave.

  • very interesting. I'll have to see what else BBC Horizon has on display :)

  • People this isnt the complaining box. No one cares
