What is a slow, continuous process while what is sudden and less frequent.
vladimir2022 [97]

Explanation:

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.

Why is it difficult to fossilize large animals?
Dennis_Churaev [7]

Answer:

The hard parts of organisms, such as bones, shells, and teeth have a better chance of becoming fossils than do softer parts. One reason for this is that scavengers generally do not eat these parts. Hard parts also decay more slowly than soft parts, giving more time for them to be buried.
