Idea that species evolve quickly with long periods of genetic equilibrium in between C. idea that species evolve slowly through gradual change of adaptations D. theory used by high school students when homework is assigned.

19. Punctuated Equilibrium B 19. Punctuated Equilibrium B. Idea that species evolve quickly with long periods of genetic equilibrium in between Analogy- Imagine that genetic equilibrium is a balloon, just minding its own business, nothing changing.
