According to the theory of punctuated equilibrium at what rate does speciation occur

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.  

mountains can affect the climate of nearby lands. in some areas, mountains block rain, so that one side of a mountain range may be rainy and the other side may be a desert. much of airborne moisture falls as rain on the windward side of mountains.
