Organic evolution refers to the gradual process through which species of organisms change over time through adaptations that occur as well as through the mechanisms of natural selection, genetic drift, mutations, and gene flow. This concept emphasizes that these changes are not instantaneous but rather occur over long periods, reflecting how species adapt to their environments and evolve. This gradual change is evidenced by the fossil record, genetic studies, and observable variations in populations over generations.

The other statements, while they touch on elements of biology, do not encapsulate the overall concept of organic evolution accurately. Sudden changes in organisms may refer to more drastic evolutionary events such as punctuated equilibrium, which does not represent the typical understanding of gradual evolution. The statement focusing solely on mutations highlights only one mechanism of evolution rather than evolution as a comprehensive process. Lastly, the interaction of organisms with their environment is an important aspect of ecology, but it does not specifically define the concept of organic evolution itself. Thus, recognizing organic evolution as a gradual change is essential for understanding how species develop and diversify over time.
