extinction and coevolution
They describe different things, so they cannot really be compared. Natural selection is the mechanism that gives direction to evolution. Punctuated equilibria is a model for the varying rates of adaptation caused by natural selection.
Punctuated equilibrium is a model of evolution in which species exhibit long periods of stasis, where little change occurs, punctuated by brief periods of rapid change. This theory suggests that most evolutionary change happens over relatively short periods of time during events like speciation.
Both gradualism and punctuated equilibrium are theories of evolution. They both propose that species evolve over time in response to their environment. The main difference is in the pace of change - gradualism suggests that evolution occurs slowly and steadily, while punctuated equilibrium proposes that it occurs in rapid bursts separated by long periods of stasis.
Stasis in the theory of punctuated equilibrium refers to long periods of evolutionary stability without significant change in a species. It occurs between rapid bursts of evolution (punctuation) that result in new species formation. Stasis can occur when a species is well-adapted to its environment and experiences little external pressure to change.
Both gradualism and punctuated equilibrium are theories of evolution that describe the pace at which species evolve over time. Both theories acknowledge that evolution occurs, albeit at different rates. Gradualism posits slow, continuous changes over long periods, while punctuated equilibrium suggests that long periods of stability are punctuated by sudden bursts of rapid change. Both theories emphasize the importance of natural selection in driving evolution.
Punctuated Equilibrium, I believe is the answer.

Punctuated Evolution or equilibrium
It is called Punctuated Equilibrium. Some Evolutionary apologists, notably Richard Dawkins, have down played this aspect of Neo-Darwinistic theory.
Punctuated equilibrium.
No difference.
Punctuated equilibrium predicts that a lot of evolutionary change takes place in short periods of time tied to speciation events.

This is the idea called punctuated equilibria, by paleontologists Stephen Jay Gould and Niles Eldredge. It explains the patterns seen in the fossil record.
