Evolution: frog adaptation (Evolution)

DAVID's comment: This contrasts with other rapid evolutionary events like the Cambrian explosion or the sudden bush of hominins. Either evolution is not a consistent progressive mechanism at all times or there is a monkey in the works, God, who picks and chooses when advances happen.

Could it not be that different local environments require minor changes (finches’ beaks, froggy fiddles) or major changes (when whales switch from land to water), whereas major widespread environmental changes (the Cambrian) spark major innovations?
