Dolly, the first cloned sheep by Mathieu Polak
The 5th of July marks 25 years since the world’s most famous sheep, Dolly, was born. The rst mammal cloned from an adult somatic cell, she made headlines around the world when her existence was announced a few months later in 1997 due to the scienti c advances she represented. Cloned from the cell of a mammary gland, she was rather cheekily named after the country singer Dolly Parton, notably famous for her generous assets. Dolly (the sheep) died shortly before her seventh birthday, from a disease not considered to be related to her being a clone. Her legacy in scienti c elds including stem cell research, medicine and the potential to save extinct species continues to this day.
