Question

Quizplus · Accepted Answer

Vicariant events refer to geological or physical events that cause a population of species to become divided into two or more geographically isolated populations. This division leads to the evolution of separate, distinct populations that may diverge genetically and morphologically over time, potentially leading to speciation. Therefore, vicariant events result in a species being divided into two or more populations that are discontinuous geographically.
