What if scientists could make an exact copy of an animal — like a real-life copy machine for living things?

The Day Scientists Cloned a Sheep Named Dolly!

Meet the world's most famous sheep who changed science forever

Scientists announced they cloned a sheep named Dolly — the first mammal copied from an adult cell!

On May 22, 1997, something absolutely mind-blowing was announced to the world: scientists in Scotland had created an exact copy of a sheep! Her name was Dolly, and she was the first mammal ever cloned from an adult cell.

But wait — what does 'cloned' mean? Imagine if you could make a perfect twin of yourself, not a brother or sister, but an EXACT copy with the same DNA! That's basically what scientists did with Dolly.

A team led by Dr. Ian Wilmut at the Roslin Institute took a tiny cell from one sheep and used it to create baby Dolly. She was born on July 5, 1996, but the world didn't find out until May 22, 1997, when scientists published their discovery.

Why was this such a big deal? Before Dolly, most scientists thought this was impossible! They believed you couldn't take a regular cell from a grown-up animal and turn it into a whole new creature. Dolly proved them wrong!

💡 Dolly was named after country music star Dolly Parton because she was cloned from a mammary (chest) cell, and Dolly Parton was famous for her... well, big personality!
