Dolly the Cloned Sheep Put to Death - Fri Feb 14, 5:40 PM ET by EMMA ROSS, AP Medical Writer

LONDON - Dolly the cloned sheep was put to death Friday, after premature aging and disease marred her short existence and raised questions about the practicality of copying life.

The decision to end Dolly's life at age 6 — about half the life expectancy of her breed — was made because a veterinarian confirmed she had a progressive lung disease, according to the Roslin Institute, the Scottish lab where she was created and lived.
