1996 – Dolly the sheep becomes the first mammal cloned from an adult cell.

Dolly (5 July 1996 – 14 February 2003) was a female domestic sheep, and the first mammal to be cloned from an adult somatic cell, using the process of nuclear transfer.She was cloned by Ian Wilmut, Keith Campbell and colleagues at the Roslin Institute and the biotechnology company PPL Therapeutics near Edinburgh in Scotland. She was born on 5 July 1996 and she lived until the age of six, at which point she died from a progressive lung disease.

Dolly has been called “the world’s most famous sheep” by sources including BBC News and Scientific American. The cell used as the donor for the cloning of Dolly was taken from a mammary gland, 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. On Dolly’s name, Wilmut stated “Dolly is derived from a mammary gland cell and we couldn’t think of a more impressive pair of glands than Dolly Parton’s”.

After cloning was successfully demonstrated through the production of Dolly, many other large mammals have been cloned, including horses and bulls. (Wikipedia)
