patterns of rapid evolutionary changes followed by long periods of no change. options: punctuated equilibrium, species, population, gradualism

Explanation:

This term describes the evolutionary pattern where species experience bursts of rapid change, followed by extended periods of stasis (no change). The other options do not fit: "Species" is a group of organisms, "Population" is a group of the same species in an area, and "Gradualism" refers to slow, continuous evolutionary change.

Answer:

Punctuated equilibrium
