Species stay the same for a long time and then change quickly due to environmental changes.
It is called Punctuated Equilibrium. Some Evolutionary apologists, notably Richard Dawkins, have down played this aspect of Neo-Darwinistic theory.
No difference.
The punctuated equilibrium theory suggests that species tend to evolve in rapid bursts of change followed by long periods of stability. This theory proposes that evolution does not always occur gradually and uniformly, but can involve abrupt shifts in traits due to significant environmental changes or genetic factors.
No difference.
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.

Punctuated Equilibrium, I believe is the answer.
