Cloning had long been considered impossible, but in July 1996 Dr Ian Wilmut, of the Roslin Institute, in Roslin, Scotland, achieved the impossible. His achievement was kept secret until this day in 1997, when the story broke that Dolly, a seven-month old sheep, was the first clone of an adult mammal. The institute also cloned "seven sheep, including three breeds from different cell types". The institute said that the technology was "equally applicable to pigs, goats, rabbits and, indeed, any mammal".
