One of the important consequences of geographical isolation is

no change in the isolated fauna

preventing speciation

speciation through reproductive isolation

random creation of new species

Solution

Speciation is the formation of new species and the development of species diversity occurs when gene flow within the common pool is interrupted by an isolating mechanism. The isolation can occur through geographical separation of population, known as allopatric speciation.
