Abstract
Theory of evolution as proposed by Darwin has for long hinged on the fossil records to prove the process of evolution. However, the prevalent gaps in the fossils led way to the development of the punctuated equilibrium theory that was proposed by Eldredge and Gould as an alternative to Darwin’s phyletic gradualism theory. The punctuated equilibrium postulated that speciation occurs in an isolated peripheral subsect of population as a rapid change after a period of stasis. Unlike the anagenetic speciation of phyletic gradualism, punctuated equilibrium promotes the concept of cladogenetic speciation. However, punctuated equilibrium does consider rapid anagenetic speciation as a ...
