【Analysis】In July 1996, at the Roslin Institute in Edinburgh, Scotland, a special cloned lamb was born, named Dolly. Dolly's birth shocked the world. This was because she was not born through normal sexual reproduction, where a mother sheep becomes pregnant and gives birth, but rather was created from an adult sheep's cell through asexual reproduction technology to form an embryo, which then developed to maturity inside a surrogate mother sheep. Therefore, she is also known as “Dolly the Cloned Sheep.”
