How are the theories of gradualism and punctuated equilibria different?

Gradualism suggests that evolution occurs slowly and steadily over time, with small changes accumulating to result in major changes, while punctuated equilibria proposes that species remain relatively unchanged for long periods and undergo rapid evolution when faced with environmental pressures. In other Words, gradualism emphasizes a constant rate of change whereas punctuated equilibria highlights long periods of stability punctuated by sudden bursts of change.
