that rapid in terms of evolution is often misinterpreted. Sunderland, Massachusetts: Sinauer Associates, Inc. Punctuated gradualism is considered to be a variation of these models, lying somewhere in between the phyletic gradualism model and the punctuated equilibrium model. Gradualism Vs Punctuationism Essay, Research Paper. Although both believe that periods of stasis do in fact occur, punctuationists take this a step further. Even in terms of punctuationist theory, changes are really not rapid in the general sense of the term.

Saltationism holds that macromutations are the cause of evolutionary change (Dawkins, 1986). Thus, theorists of the punctuationist school should quit looking to completely discredit the gradualist school of thought, because they share many premises in common with each other. Punctuated gradualism is a microevolutionary hypothesis that refers to a species that has "relative stasis over a considerable part of its total duration and underwent periodic, relatively rapid, morphologic change that did not lead to lineage branching". First, there appear to be many large gaps in the fossil record (Dawkins, 1986). Although punctuationists have often been confused with saltationists, this is a huge mistake. Based on these findings, Malmgren and colleagues introduced a new mode of evolution and proposed to call it "punctuated gradualism.". Creationism holds that the reason for the appearance of largely different organisms in the fossil record, without organisms that display intermediate amounts of change is the presence of a divine creator.
