Dolly, the sheep, was the first mammal to be cloned from an adult somatic cell. She was created in 1996 by scientists at the Roslin Institute in Scotland. Dolly's birth marked a significant milestone in genetic research, demonstrating that it was possible to create a genetically identical organism from a mature cell. Dolly was named after the singer Dolly Parton because the cell used for cloning came from a mammary gland. She lived for six years and had several offspring. Dolly's creation raised ethical questions about cloning and its implications for science and society.
