Final answer:

Geographic isolation can lead to allopatric speciation by physically separating populations and limiting gene flow, ultimately resulting in the formation of new species.


Explanation:

Geographic isolation is the correct example in this case. Geographic barriers like a river forming a canyon can physically separate populations, preventing gene flow between them. This isolation can lead to allopatric speciation, where separate evolutionary paths are taken, ultimately resulting in the formation of new species.
