History of animal testing of visual areas in cats and monkeys, and provided physiological evidence for the critical period for the development of disparity sensitivity in vision (i.e.: the main cue for depth perception), and were awarded a Nobel Prize for their work. 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
Royana (cloned sheep) Royana (cloned sheep) Royana (2006–2010) is Iran's and the Middle East's first successfully cloned sheep. Royana was a brown male domestic sheep and was cloned in the Royan Research Institute in Isfahan, Iran (The word "Royan" means "embryo" in Persian). He was the second cloned sheep in Royan Research Institute, but whereas the first sheep died few hours after birth, Royana lived for a few years. On September 30, 2006, a group of scientists in Iran cloned Royana from an adult cell in a test tube in a laboratory. After the embryo proved its stability, scientists transferred it to the
