Punctuated equilibrium is a model that suggests species experience little evolutionary change for most of their geological history, but when they do evolve, it occurs rapidly, leading to the abrupt appearance of new species in the fossil record without much evidence of intermediate forms. This contrasts with the gradualism model, which predicts slow, steady change over time.
