How Does Gradualism Relate to Evolution

Scientists think that species with a shorter evolution evolved mostly by punctuated equilibrium, and those with a longer evolution evolved mostly by gradualism. Gradualism is selection and variation that happens more gradually. Over a short period of time it is hard to notice.

What does gradualism mean in evolution?

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.

Is evolution a gradual process?

Charles Darwin understood that evolution was a slow and gradual process. By gradual, Darwin did not mean “perfectly smooth,” but rather, “stepwise,” with a species evolving and accumulating small variations over long periods of time until a new species was born.
