Twenty years ago on July 5, 1996, the world’s most famous sheep was born. Brought into existence by a technique called somatic cell nuclear transfer, she became the first mammal to be successfully cloned from an adult cell. Named Dolly after Dolly Parton, she was named so because she originated from a cloned mammary cell and even scientists love boob jokes.
Dolly began her life in a test tube, was transferred as an embryo into a surrogate sheep mom, and was born at the Roslin Institute in Scotland.
