Twenty years ago today (22 February 1997), a team of researchers from Scotland announced that they had successfully cloned a sheep - the first mammal to be created from a single adult body cell. The sheep's name? Dolly.

What is the historical significance of this event? Is cloning a major new technology with the potential to change the world? Or was it largely a publicity stunt that has little impact on the world?
I have heard several other species have since been cloned, including a horse named Promotea in May 2003. Are we witnessing the dawn of a new historical era? And what does cloning mean for the future of the human species?
