History of animal testing
In 1996 Dolly the sheep was born, the first mammal to be cloned from an adult cell. The process by which Dolly the sheep was cloned utilized a process known as nuclear transfer applied by lead scientist Ian Wilmut. Although other scientists were not immediately able to replicate the experiment, Wilmut argued that the experiment was indeed repeatable, given a timeframe of over a year.

Keith Henry Stockman Campbell (23 May 1954 – 5 October 2012), Professor of Animal Development at the University of Nottingham, was a British biologist who was a member of the team that in 1996 first cloned a mammal, a Finnish Dorset lamb named Dolly, from fully differentiated adult mammary cells.
