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 stepsUniformitarianism incrementalism and reformism are similar concepts. Proponents of punctuated equilibrium point out that there are many missing links in the fossil record. Gradualism is the theory that explains that large morphological variations or alterations in the organisms take place by several small steps over years. Scientists think that species with a shorter evolution evolved mostly by punctuated equilibrium and those with a longer evolution evolved mostly by gradualism.
