As nouns the difference between revolution and gradualism is that revolution is a political upheaval in a government or nation state characterized by great change while gradualism is (label) the belief that evolution proceeds at a steady pace, without the sudden development of new species or biological features from one generation to the next. Punctuated equilibrium is commonly contrasted against phyletic gradualism, the idea that evolution generally occurs uniformly and by the steady and gradual transformation of whole lineages (called anagenesis) in this view, evolution is seen as generally smooth and continuous. Punctuated equilibrium (also called punctuated equilibria) is a theory in evolutionary biology which proposes that most species will exhibit little net evolutionary change for most of their geological history, remaining in an extended state called stasis.

Phyletic gradualism is the theory that one species changes to another by combining the better genetic features of the species and these genetics mutate and result in an entirely different species this change is slow and gradual and most often occurs in small populations.

Furthermore, it has been shown that speciational evolution (perhaps a better term than punctuationism) is fully consistent with darwinism and finally, that seeming evolutionary saltations, as indicated by the fossil record, can be explained without invoking systemic mutations or other mechanisms in conflict with molecular genetics.
