Dolly (July 5, 1996 – February 14, 2003) was a female domestic sheep remarkable in being the first mammal to be cloned from an adult somatic cellby Ian Wilmut, KeithCampgell and colleagues at the Roslin Institue in Edinburgh, Scotland.

The cell used as the donor for the cloning of Dolly was taken from a mammary gland (and thus the name Dolly,) and the production of a healthy clone therefore proved that a cell taken from a specific part of the body could recreate a whole individual.

The first successful cloning of a primate species using the same method for producing Dolly was reported in January 2018. Two identical clones of a macaque monkey, Zhong Zhong and Hua Hua, were created by researchers in China and were born in late 2017.
