Dolly The Sheep & Cloning
While it might be odd to think that a sheep was among the animals that inspired scientists more than once to do something incredible, it’s true. Technically, a sheep was used to offer future inspiration. In July 1996, a fuzzy little sheep came from the belly of one of her three mothers. She was the first mammal cloned from an adult cell. Dolly’s birth proved that somatic cell nuclear transfer could work. This is the process by which a cell nucleus from an adult cell is transferred into an unfertilized eff, blasted with electricity, then implanted into a surrogate. While Dolly passed away at just 6 years old, she helped to prove cloning was possible. Ever since then, we’ve cloned even larger animals from pigs to horses and bulls. We even have plans in place to try to clone a human being one day.
