WebMar 17, 2024 · In modern biology, gradualism, or “phyletic gradualism,” refers primarily to a pattern of sustained, directional, and incremental evolutionary change over a long period during the history of a species. With the introduction of the theory of punctuated equilibrium, gradualism has been contrasted with stasis (species’ relative morphological ... WebMicroevolution is evolution on a small scale — within a single population. That means narrowing our focus to one branch of the tree of life. If you could zoom in on one branch of the tree of life scale — the insects, for example — you would see another phylogeny relating all the different insect lineages.
