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.
Dolly!
In the mid-1970s, Parton was approached by Bill Graham, president of Show Biz, Inc., the same company that produced "The Porter Wagoner Show" (on which Parton had costarred for seven years), and soon afterward the syndicated variety show "Dolly" was born.
