Here are the correct answers that would complete the given statement above. The answers would be GRADUALISM and PUNCTUATED EQUILIBRIUM, respectively. Gradualism is a slow, continuous process while punctuated equilibrium is sudden and less frequent. Hope this answer helps you.
A slow, continuous process is defined as gradualism that occurs at slow rate but at a steady pace.
For example, stripes of a tiger develop slowly and at a steady pace so that they can hide in tall grass represents gradualism.
Whereas punctuated equilibrium is a process in which there is sudden and frequent changes that results in the formation of new species.
For example, species living in a sea for thousand of years breed and die over there and suddenly when there is change in sea level than animals must adapt represents punctuated equilibrium.
