One of the important consequences of geographical isolation is:
preventing speciation
speciation through reproductive isolation
random creation of new species
no change in the isolated fauna.
Solution
Speciation is the evolutionary process for the formation of new species. The species diversity occurs when gene flow within the common pool is interrupted by an isolating mechanism.
Related Theory
The isolation can occur through geographical separation of population known as allopatric speciation. When a few individuals of a species within the same geographical area suddenly become reproductively isolated and form new species, it is known as sympatric speciation.
