Dolly, the first clone from a mammal, died yesterday at the age of 6 years old.
Where were you on July 5, 1996? What did you think when you read the news about the accomplishment of Ian Wilmut  and his team at Roslyn Institute in Edinburgh? What is Dolly's lasting historical significance? How does Dolly's life change our view of humanity?
Condolences to Ian Wilmut and his colleagues on this sad event.
