The concept of Regression has been implied a bit in past redwall novels. Not 'instanous' regression, per se, but theres an underlying element of the primitive if you know where to look.
Take the Dirgecallers for example(Free self image points!) they did not speak or otherwise show any sign to indicate that they were sentient. They were completely obsessed with killing and bloodlust. I would say thats regression right there. Especially considering in Rakkety Tam, the Ermines are fully sentient.
Which brings me to....
Gulo. This wolverine is teetering right on the edge of sentience. Seriously, it makes me wonder...were wolverines the last species to evolve sentiency in the Redwall Universe? He was insane, true and blinded by rage. BUT there were hints that the whole family was like this as well. So for those of you who still defend Askor...remove the tree and see how long it takes for him to eat you.
Primeval monsters such as the DeepCoiler and the Slothonaug abound. This brings to my mind that Redwall is not that far advanced from a dark and scary age. (The redwall version of the meszoic?) Seriously, anyone who has seen the artists depiction of the Slothonaug should probably be frightened. That *pliesliosour* was the biggest creature that has been in Redwall before (short of a whale).
Anybody have any other examples of regression in the books?
*Hint*
Blood...
finish the sentence.
