Question

What do gradualism and punctuated equilibrium have in common?

Answer 1

That they are both theories of evolutionary change, but the tempo of the change is different enough that we have the two theories. Rapid evolutionary change punctuated with long periods of stasis describes the former while gradual and incremental change over long periods is the description of the later. Natural selection seems to be more important in gradualism than punctuation, but this is a murky area that is argued about often.

Answer 2

The answer is A:

"They are both explanations of the rate of evolutionary change."

Good luck!
