Detailed explanation-1: -The theory of punctuated equilibrium states that evolutionary change is characterised by short periods of rapid evolution followed by longer periods of stasis in which no change occurs.

Detailed explanation-2: -“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-3: -In biology, saltation (from Latin saltus ‘leap, jump’) is a sudden and large mutational change from one generation to the next, potentially causing single-step speciation.

Detailed explanation-4: -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.

Detailed explanation-5: -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.
