Answer to Question #123006 in Evolution for NIBEDITA RUDRA

Question

Define Vicariant Distribution

Answer 1

Vicariant distribution is an isolation of the species population due to the movement of continents, formation of islands, mountains, glaciers, and water bodies that separate the species populations leading to their further speciation. As a result, vicariant distribution is observed when the same or related species inhabit different locations commonly separated by geological barriers.
