Answer 1

Punctuated equilibrium refers to B. Species that evolved very rapidly during relatively brief time spans

Step-by-step explanation:

The theory of evolution states that organisms heritable characteristics change over time to form new lineages or species. Punctuated equilibrium is an evolutionary theory that explains the sudden appearance of novel species on the fossil record. In this theory, the species likely evolved quickly to survive in a significantly altered environment.
