Separation … Allopatric speciation (from Ancient Greek ἄλλος (állos) 'other', and πατρίς (patrís) 'fatherland') – also referred to as geographic speciation, vicariant speciation, or its earlier name the dumbbell model – is a mode of speciation that occurs when biological populations become geographically isolated from each other to an extent that prevents or interferes with gene flow. Summary. The difference in environmental factors causes the change in allopatric speciation. Vicarious or dicopatric allopatric speciation. Allopatric speciation (sometimes referred to as allopatric isolation) is the most common type of speciation observed in nature.
