Dolly the sheep

Dolly (5 July 1996 – 14 February 2003), a ewe, was the first mammal to have been successfully cloned from an adult cell. She was cloned at the Roslin Institute in Scotland and lived there until her death at the age of six. Scientists announced her birth on 22 February 1997.

Death

On 14 February it was announced that Dolly had a progressive lung disease. A necropsy confirmed she had sheep pulmonary adenomatosis, a fairly common disease of sheep. Roslin scientists stated that they did not think there was a connection with Dolly being a clone, and that other sheep on the farm had similar ailments.
