Hint- Gradual: means slowly i.e. I pour the water gradually into the cup.
Gradualism- species evolve slowly
(Although I think answer D works as well!)

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. And then all of a sudden you puncture it with a needle, suddenly everything changes.
