WebVicariant Speciation. Vicariant speciation—also known as dumbbell speciation—occurs when a physical barrier, like a river or a valley, splits a population of a single species into two or more reproductively isolated groups.This process is illustrated in Figure 3 below.

Mutation, migration, genetic drift, and natural selection are all processes that can directly affect gene frequencies in a population.

WebJul 22, 2024 · During continental drift plant and animal species are most likely to evolve or become extinct because of climate change. Continents moving towards a pole means less energy from sunlight which means lower temperatures and less vegetation. Continents moving towards the equator will have a warmer climate.
