Real-life clone? This sheep, named after a famous singer, was the world's first successful living replica

Dolly the sheep, the first cloned mammal, was born in Scotland in 1996. Her birth sparked global debate about the ethics and safety of cloning technology. Dolly mated and had four lambs, but later developed arthritis and lung disease. Cloning mammals remains inefficient, with epigenetic reprogramming posing a significant challenge. This research also advanced the discovery of induced pluripotent stem cells for medical use.
