Correct option is C
Correct Answer: (c)
Explanation: Gradualism explains evolutionary change as a slow and continuous process driven by the accumulation of small variations over long periods of time. Punctuated equilibrium, in contrast, proposes that species remain in relative morphological stasis for most of their existence, with evolutionary change occurring rapidly during brief speciation events. Thus, option (c) accurately contrasts the two models.
Information Booster
· Gradualism is closely associated with Darwin’s original view of evolution.
· Punctuated equilibrium was proposed by Eldredge and Gould.
· Both models accept natural selection as a major evolutionary mechanism.
· The difference lies mainly in the tempo and pattern of evolutionary change.
· Punctuated equilibrium helps explain gaps and sudden appearances in the fossil record.
