What does biogeographic isolation lead to

The bio-geographical isolation leads to speciation

Explanation:

The biogeographic isolation, which is the separation of a species because of the physical and biological forces leads to the evolution of the species into new, distinct ones. These new species that evolved due to isolation and is not any more reproductively compatible with the parent species. In the evolution the environmental changes and evolution has the significant role. Because certain changes in the environmental condition allows them to adapt the changes so as to survive, which makes it an evolution and gives a new species.
