The punctuated equilibrium theory argues that minimal or no change in an organism takes place after speciation but Darwinism theory argues that evolution occurs gradually and constantly over time (Geoff 2000). Increased populations and limited resources lead to natural selection but the according to the punctuated theory, isolation of a section of population and limitation of food are the main drivers of speciation. The theory of punctuated equilibrium also asserts that mutation occurs in the population faster and favorably due to the small numbers of the members of that group (Hannah 2006). The two theories also have differences in the way organisms are formed. Darwin asserts that the species transform into a morphologically and genetically improved species while the punctuated theory asserts that a split of the species occurs leading to the formation of two species with distinct features which they retain until they become extinct.
