What do gradualism and punctuated equilibrium have in common?

They are both explanations of the rate of evolutionary change.

Explanation:

Gradualism is that evolution occurs at a slow and steady pace. Gradualism brings small variation to particular species, it occurs over a long period of time.

In punctuated equilibrium, change comes in spurts. Punctuated Equilibrium is the time in which species are stable but now and then there is a disruptive event that promotes frequent changes.
