Question

The evolutionary theory that suggests that a species can suddenly and rapidly evolve into a new species is
A.genetic drift
B. gradualism
C. punctuated equilibrium

Answer 1

Any guess? :)

Answer 2

Read this:

Gradualism and punctuated equilibrium are two ways in which the evolution of a species can occur. A species can evolve by only one of these, or by both. Scientists think that species with a shorter evolution evolved mostly by punctuated equilibrium, and those with a longer evolution evolved mostly by gradualism.
