It is actually another theory explaining how a new species arises.
The theory itself states that a species goes a long time without change, then suddenly changes.
It is called Punctuated Equilibrium. Some Evolutionary apologists, notably Richard Dawkins, have down played this aspect of Neo-Darwinistic theory.

Punctuated equilibrium is a theory in evolution that suggests long periods of stability with sudden bursts of significant change. Therefore, gradual and continuous evolution is not a characteristic outcome of punctuated equilibrium.
The theory of puctuated equilibrium.
The pattern described by the theory of punctuated equilibrium is that bursts of evolutionary activity are followed by long periods of stability.
punctuated equilibrium
Stasis in the theory of punctuated equilibrium refers to long periods of evolutionary stability without significant change in a species. This stasis occurs between shorter bursts of rapid evolutionary change or speciation events.
