Can Punctuated Equilibrium and Gradualism?

Scientists think that species with a shorter evolution evolved mostly by punctuated equilibrium, and those with a longer evolution evolved mostly by gradualism. Gradualism is selection and variation that happens more gradually. Over a short period of time it is hard to notice.

How does punctuated equilibrium relate to gradualism?

For Gradualism, changes in species is slow and gradual, occurring in small periodic changes in the gene pool, whereas for Punctuated Equilibrium, evolution occurs in spurts of relatively rapid change with long periods of non-change.

How are gradualism and punctuated equilibrium similar?

Both gradualism and punctuated equilibrium describe the rates of speciation. For Gradualism, changes in species is slow and gradual, occurring in small periodic changes in the gene pool, whereas for Punctuated Equilibrium, evolution occurs in spurts of relatively rapid change with long periods of non-change [1].
