Question

Quizplus · Accepted Answer

The appearance of a physical barrier that splits the range of a species is called a vicariant event. Vicariance refers to the splitting of a continuous geographic range into two or more isolated parts by the appearance of a physical or environmental barrier, such as a mountain range, a river, or a sea. The resulting isolation can lead to the evolution of distinct species in each of the isolated areas over time.
