Question

Quizplus · Accepted Answer

The punctuated equilibrium model proposes that evolution occurs in short bursts of rapid change followed by long periods of stasis. This pattern is seen more clearly in the fossil record at the phenotypic level, where distinct species suddenly appear and then remain relatively stable for long periods, rather than at the genotypic or molecular level. The phyletic gradualism model suggests that evolution occurs slowly and steadily over time, which may be more applicable at the molecular level.
