Which of the following is most likely to contribute to the emergence of new species?

Question

Quizplus · Accepted Answer

Minimal gene flow between populations can lead to the accumulation of genetic differences over time, potentially resulting in the emergence of new species. Gene flow between populations can act to homogenize gene pools and prevent divergent evolution.

Answer: D 
 Mutations within a given population can create new genetic variations, which can eventually lead to the emergence of new traits and potentially new species. However, this process would be slower than the isolation of populations through limited gene flow in choice A.
