'He is indeed the best of animals,' replied Rat, 'So simple, so good-natured, and so affectionate. Perhaps he's not very clever - we can't all be geniuses, and it may be that he is both boastful and conceited. But he has got some great qualities, has Toady.'

Re-evolution!

This is really amazing!! There is an article about a frog who went through re-evolution!It's called the Gastrotheca guentheri frog. It is a marsupial frog so that means it has a pouch.  The article says;

A new analysis of the frog family tree reveals that the common ancestor of frogs, which long had lower-jaw teeth, lost them more than 230 million years ago before eventually going extinct.       
Then 15 million years ago, they got lower teeth back! It is really so amazing! you HAVE TO READ IT!!!

They still dont know why the teeth came back, but I hope thay can find out.

apereantly, frogs aren't the only ones re-evolving...

In general, losing complex features is common in evolution. Humans and frogs have lost their tails, most snakes have lost limbs, and birds and turtles have lost teeth, according to the study.
But in the past eight years or so, more studies have found evidence of these advanced characteristics springing up again—for instance, wings in stick insects and fingers and toes in lizards.
  This is just VERY amazing!
