It allows divergence to occur
It allows populations to become genetically different.
They are thought to have separate paths of evolutionary development.
They developed along different evolutionary paths.
They had independent evolutionary development.

Tissue development
Development of a coelom
Allopatric Speciation (geographic isolation) can lead to the formation of a new species because the population is split in two smaller populations by a physical barrier (river, canyon, mountain...).
