Evolution of Frogs

Evolution of Frogs

Awesome Article!

About 230 million years ago, frogs had teeth.  Professor John J. Wiens from The Department of Ecology and Evolution.  These frogs had to adapt because they didnt have long tongues in that time period.  They only had sharp teeth and struggled to eat.  Their diet consists of bugs and they couldnt catch bugs as easily.  Its said that with "Dolo's Law" these frogs will never lose their long tongues.
