1997 to 2000: Scientists at various institutes cloned various species of animal – as other scientists claimed to be working towards the first human clone.
1998: American Dr Richard Seed said he was ready to begin experiments on cloning a human being within the next three months.

July 2003: The first UK research licence of its kind permitting a technique that creates embryonic stem cells from human eggs was granted to the scientists who cloned Dolly the sheep in Edinburgh. This is therapeutic, not reproductive, cloning.
September 2003: Dr Panos Zavos claims to have created the world’s first cloned human embryo. He announced plans to implant the human embryo in a surrogate mother later in the year.
October 2003: scientists in China claimed they had created twins which effectively had two “genetic mothers” and one father, but the experiment did not create any live babies. One expert called the experiment “proof of principle” for human cloning, but others disagreed. The work was not aimed at producing genetic copies of humans.
