Which statement best describes gradualism in evolution?

Explanation:
Gradualism is the idea that evolution happens through small, incremental genetic changes that accumulate over long periods of time, gradually leading to bigger differences. That’s exactly what the statement describes: small changes piling up over time to produce large differences. The other ideas describe different patterns or mechanisms—changes happening in big leaps (punctuated equilibrium), speciation that isn’t tied to geographic separation, or a process like endosymbiosis that explains origin of cellular organelles rather than the tempo of evolutionary change.
