The African Clawed Frog cannot usually grow legs. But one frog in a university in the US did. Scientists gave it special medicines for 24 hours. Now, a year and a half later, it has a whole new leg.

Biologists think the medicines could be used on humans. People who have lost a limb could have a new one. But why stop there? We could grow new body parts like tails or bigger ears.

Yes! It would be great. You could do all sorts of tasks at once. Tails are useful too. We could use them to swat flies like cows do. Or we could use them for balancing. We should all grow more body parts!

No. This is silly. The medicine will help people who really need it. It is dangerous to use it in unnatural ways. We could end up with too many arms. Or worse, it could make us ill. We should be careful.
