    Dolly the Cloned Sheep Put to Death

    Dolly the sheep, the world's first mammal cloned from an adult, was euthanized after being diagnosed with progressive lung disease, her creators said Friday.

    The decision to end the life of 6-year-old Dolly was made after a veterinary examination confirmed the lung disease, a statement from the Roslin Institute said.

    Dr. Harry Griffin of the institute said Friday that sheep can live to 11 or 12 years and lung infections are common in older sheep, particularly those like which are kept indoors.

    "A full post-mortem is being conducted and we will report any significant findings," Griffin said.

    Dolly was born July 5, 1996 in a research compound of the Scottish institute, and she created an international sensation when the achievement was announced on Feb. 23, 1997.

    Researchers had previously cloned sheep from fetal and embryonic cells, but until Dolly it was unknown whether an adult cell could reprogram itself to develop into a new being.

    The Dolly breakthrough heightened speculation that human cloning inevitably would become possible.

    Dolly, a Finn Dorset sheep named after the singer Dolly Parton, bred normally on two occasions with a Welsh mountain ram called David, first giving birth to Bonnie in April 1998 and then to three more lambs in 1999.

    In 1999, scientists noticed that the cells in Dolly's body - cloned from a 6-year-old sheep - had started to show signs of wear more typical of an older animal.

    Then in Jan. 2002, her creators announced she had developed arthritis at the relatively early age of 5 1/2 years, stirring debate over whether cloning procedures might be flawed.

    Some geneticists said the finding provided evidence that researchers could not manufacture copies of animals without the original genetic blueprint eventually wearing out.

    There are now hundreds of animal clones around the world, including cows, pigs, mice and goats, many of them appearing robust and healthy.

    But many attempts to clone animals have ended in failure. Deformed fetuses have died in the womb with oversized organs, while others were born dead. Still others died days after being born, some twice as large as they should have been.

    Dolly's body has been promised to the National Museum of Scotland and will eventually be put on display in Edinburgh, the Roslin Institute said.

    It's not just sad, although it IS that -- but they talk of cloning humans. Too much is going too wrong with clones -- how can we risk babies to this experiment?

    Pure Greed Helen, It all comes down to who can patent the right process and make the most money. Apparently even Adolph Hitler had scientists working on cloning, to create his master race.

    Yet cloning always ends in deformaty and premature death.

    It is sad. Cloning is very similar to the abortion industry. It involves a total disregard for the wellbeing of the infant affected. It also involves an overwhelming desire to have total control for the creation and termination of life.

    Every baby should have a mother and/or a father, less than that is cruel and unusual punishment.

    Watched something on cloning recently, which
    speculated that there is a possibility that cloning
    is failing because when a needle is used to
    penetrate the egg, it may be piercing the egg in
    the wrong place at the wrong time. They thought
    this was the reason for the over-sized organs as
    well as the large resulting animal and the
    tendency toward particular diseases.

    We have all seen the little sperm, their tails
    spinning wildly, as they surround an egg in a
    petrie dish, trying to gain entry. In all those
    places where the sperm attempts entry, they do
    not make it, except for that one sperm. Why? Is
    there a particular point on the egg, which to us
    looks like a very simple organism, the same
    everywhere WE can see, but it simply is not the
    same? Is there, perhaps, a particular point of entry
    which makes the difference, as well as a particular
    time on that egg's schedule that we do not know?

    Abiyah, I think, basically, you have hit the nail on the head. There has been an assumption for a long time that genes are all that determine the new organism and that the rest of the cell sort of exists to perpetuate the genes. Under this misconception, just shooting a new batch of genetic material into an egg should be all that is needed for cloning.

    But more and more research is showing that the genetic material in the nucleus is only part of the story. For instance, we have no idea how an E.coli bacteria knows how to be the shape it is. There is nothing in the genes which seem to indicate shape. There is some kind of interaction with the cell itself which is still not understood.

    And that is aside from point of entry for the sperm in sexual reproduction.

    The whole process is appearing to be MUCH more complex than anyone recognized (let alone understood!) up until now. I am aware of two biochemists who are deeply involved in research regarding this right now. One is busy pulling together material for a book, I think, and the other is still in the lab. The results will be interesting, at the very least.

    I am not the least bit surprised; we always think
    we know so much, only to have a later generation
    prove to us how little we had known. Ask
    someone from the 19th century what an atom is.

    What makes us think we can see, even wih our
    most powerful microscope, that egg and all its
    facets. Not likely. Our God and Creator cannot
    be put in a box.

    This highlights the concerns that were expressed on the birth of Dolly.

    Sorry to say that this "experiment" happened over here, but glad that once it happened the legislation was put in place to prevent cloning of humans in this country.

    yours, Jon.

    Oh, you're talking about a SHEEP! :eek: :eek: :eek:

    Man, I was thinking this was about Dolly Parton! :rolleyes:

    Me, too, Bob. I came here to see what had happened to the only Dolly I know, and was pleasantly surprised to find the topic of discussion was only a sheep! [​IMG]

    I used to know a lady-preacher named Dolly.
    Didn't look one bit like Dolly Parton.
    Or like a sheep, for that matter.

    Thanks to the science of cloning, we can now produce crown roasts in half the time.
