    On the basis of the theory of punctuated equilibrium, after the periods of stasis, new species evolve comparatively rapidly.

    An evolutionary theory, which deals with the concept of stasis, that is, a state of no or little morphological change is known as punctuated equilibrium. It illustrates the pattern of speciation witnessed in the fossil records.

    Till the organisms come across an evolutionary pressure, they are in a state of stasis. The evolutionary pressure leads to a brisk process of speciation. After the appearance of the species in the fossil records, the stability of the population takes place will little or no evolutionary change. They further go through minimal or no evolutionary change for the majority of their geological time scale.

    According to the theory of punctuated equilibrium speciation occur at high rate.

    Punctuated Equilibrium is a theory about how the evolutionary process works and it describes how species originate rapidly.

    Shortly described, punctuated equilibrium can be represented by a group of organisms that get isolated from the rest of their species. They evolve fast, because they are a small group and then they can spread and replace their parent species.
