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.
Roger Burton Land
Roger Burton Land FRSE (1940-1988) was a relatively short-lived but important 20th century British animal geneticist. As Head of the Edinburgh Research Station he was one of the several scientists responsible for laying the groundwork for the creation of Dolly the Sheep. The Roger Land Building within Edinburgh University's King's Buildings complex is named after him.
