Cloning is now 9 years old
22 Feb 1997 - Scientists at the Roslin Institute in Scotland announced the birth of a cloned sheep named Dolly .
Hard to believe huh? 9 years have passed since Dolly was first cloned.
Here's some fact you might not have known about Dolly and Cloning.
As you can see cloning is still in its infancy. We have made large strides in stem cell research though. Diseases like Parkinsons and Alzhimers now have hopes of a cure thanks to stem cell research. And in another 20-40 years perhaps we'll have figured cloning out.

Here's some fact you might not have known about Dolly and Cloning.
- the success rate has been very low: Dolly was born after 276 failed attempts; 70 calves have been created from 9,000 attempts and one third of them died young
- A surprising development to do with aging resulted from finds that Dolly was apparently subject to accelerated aging.
- Cloning is quite inefficient and usually there are over 600 to 1000 nuclear transfers before one is able to grow into a stem cell. Even those animals that are successfully cloned are not as heathly as the original animal.
