Description: (British Embryologist Known for Creating a Cloned Sheep Named 'Dolly' From an Adult Sheep’s Somatic Cell)
British biologist Ian Wilmut revolutionized embryology by leading the team of researchers who successfully created the first cloned mammal, the sheep named Dolly. A leading proponent of cryopreservation, he also implanted the first calf embryo, Frostie, in a surrogate cow. He was later knighted for his achievements.
