Explanation:

Punctuated equilibrium proposes that species undergo relatively rapid bursts of evolutionary change (speciation) in short periods of geologic time, often triggered by environmental changes or other factors, followed by long periods of stasis (little or no evolutionary change).

Here’s why the other options don’t fit:

A.Speciation occurs due to natural selection: Natura...
