Which of the following cannot be the result of punctuated equilibrium

extinction and coevolution

adaptation and speciation

stasis and expansion

Punctuated equilibrium is defined as a theory in the evolutionary biology in which it states that when one specie appears in the fossil record they will become stable, and that it will only show little evolutionary change for most of their geological history. Therefore, the option that cannot be the result of punctuated equilibrium is extinction and coevolution. The correct answer is option A.
