DescriptionHello Dolly Dolly the sheep was born on 5 July 1996, the first animal to be cloned from an adult body cell. When her birth was announced publicly in February 1997, it caused a widespread media sensation. Dolly's birth disproved the theory that differentiation - the process where a fertilised egg develops into hundreds of different cell types - was irreversible. Dolly also demonstrated that cloning did not affect fertility by giving birth to healthy lambs. Dolly's relatively early death at the age of six in 2003 led to speculation that cloning had aged her genes prematurely, but in fact her death was due to a virally induced lung cancer unconnected with cloning. As the cells used to create Dolly originated from mammary glands, she was named after the singer Dolly Parton.
