Question

multiple choice question
geologically short periods of rapid evolutionary change and long periods of stasis are the two main processes identified in the hypothesis known as

○ adaptive radiation
○ punctuated equilibrium
○ sympatric speciation
○ gradualism

Explanation:

Punctuated equilibrium proposes short bursts of rapid evolutionary change followed by long periods of stasis. Adaptive radiation is the diversification of a group into new forms. Sympatric speciation is the formation of new species in the same geographical area. Gradualism suggests slow, continuous evolutionary change.

Answer:

B. punctuated equilibrium
