Dolly The Sheep
One of the most important scientific breakthroughs in history was the first successful cloned mammal. The cell used to clone the animal was taken from a mammary gland of a sheep and resulted in the creation of another sheep which was called named “Dolly”.
“Dolly is derived from a mammary gland cell and we couldn’t think of a more impressive pair of glands than Dolly Parton’s,” said one of the scientists.
