Webpunctuational evolution. I have suggested that the punctuational model be defined as the assertion that most evolution is as-sociated with speciation by way of local-ized populations (Stanley, 1979 p. 16). The traditional, gradualistic model repre-sents the alternative position, that most evolution occurs within established species. Gradualism, from the Latin gradus ("step"), is a hypothesis, a theory or a tenet assuming that change comes about gradually or that variation is gradual in nature and happens over time as opposed to in large steps. Uniformitarianism, incrementalism, and reformism are similar concepts. phoenix fire station 11
