Allopatric speciation (from Ancient Greek ἄλλος, allos, meaning "other", and πατρίς, patris, "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. competitive exclusion. This means that the same species living in two different areas will start to have different traits. When a population disperses throughout an area, into new, different and often isolated habitats, multiple speciation events can occur in which the single original species gives rise to many new species; this phenomenon is called adaptive radiation. Median response time is 34 minutes and may be longer for new subjects. *Response times vary by subject and question complexity. Thus, the frequency of an allele at one end of a distribution will be similar to the frequency of the allele at the other end.
