Dolly (5 July 1996 – 14 February 2003) was and is perhaps the most famous sheep in the world. She was "the first animal to be cloned from an adult somatic cell, using the process of nuclear transfer." (wiki)
The article offered here, found In Nature 385, February 27, 1997, pp. 810-813 with a commentary by Stewart later in the issue 769-771 documents this important event with a photograph of a young Dolly on the cover of the journal. The success of this attempt (Dolly lived for 6 years) has spawned both lively debate about the possible ethical issues involved and also when (or if) similar processes should be applied to humans. Other attempts based on the same process have generated limited successes.
In future years we expect this seminal event to have even more meaning as society attempts to navigate both the technical and societal impacts of future successes and failures.
