Detailed explanation-1: -You can remember those by equilibrium, or stasis, that stays the same for a long time and then is punctuated by rapid bursts of change, and gradualism . Phyletic gradualism is going to happen slowly continually gradually over time.

Detailed explanation-2: -Punctuated equilibrium can also happen because of gene mutations. For example, a cheetah species has no spots. However, due to a gene mutation, a cheetah cub is born with spots. Because this adaptation helps the cheetah to hide and survive, more cheetahs are born with spots.

Detailed explanation-3: -“Punctuated equilibrium is the idea that evolution occurs in spurts instead of following the slow, but steady path that Darwin suggested. Long periods of stasis with little activity in terms of extinctions or emergence of new species are interrupted by intermittent bursts of activity.”

Detailed explanation-4: -However, punctuated equilibrium is any sudden, rapid change in a species and can also be the result of other causes, such as huge and sudden changes in the environment that result in more rapid changes in the organisms through harsher selection.

Detailed explanation-5: -In evolutionary biology, punctuated equilibrium (also called punctuated equilibria) is a theory that proposes that once a species appears in the fossil record, the population will become stable, showing little evolutionary change for most of its geological history.
