Similar:
Both theories tell about evolution by natural selection, change over time, and how organisms adapt to their environment.

Gradualism explains the slow changes that happen over a long time when the environment changes slowly.

Punctuated equilibrium explains the sudden changes that accompany sudden environmental changes (like changes after an asteroid impact).
