In punctuated equilibrium, change comes in spurts. ... 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.
In what instances might punctuated equilibrium occur?
Punctuated equilibrium states evolution only takes place in bursts of time that are rapid. However, the term "rapid," in evolutionary terms should be understood to mean approximately 500,000 years in some circumstances. So for example, a species of sea animals lives, breeds and dies for thousands of years.
Is gradualism accepted?
Two Competing Theories of Evolution
Generation after generation can come and go before any changes in a species are observed. There is some debate in the scientific community as to how quickly evolution occurs. The two generally accepted ideas for rates of evolution are called gradualism and punctuated equilibrium.
