Reproductive isolation separates the reproduction of one population into two populations. Over time after generations, the two separate populations start living and reproducing differently, so they evolve into two separate species, which is speciation (also known as divergent evolution). Reproductive isolation and speciation reduces gene flow.
Reproductive isolation prevents variations from spreading throughout the entire population. Since genetic variations basically occur randomly, the chances that the same variations will occur in both reproductively separated subpopulations are vanishingly slim. Thus, genetic divergence between both subpopulations will occur, and this may eventually lead to speciation. Isolation stops populations of the same species from interbreeding. This results in separate breeding among populations and genetic differences become more pronounced with each generation.

It is caused by damage to the language-dominant brain that separates all or parts of the central region from the rest of the brain
It reduces gene flow.
Once a single species is physically separated into two or more populations, genetic drift often permanently separates those populations into distinct species no longer able to interbreed, even if they should later again intermingle.
US presidents are elected by the people through a rather complicated process that separates the votes by state and keeps states with large populations from totally dominating the elections.

disruptive selection
If a land mass separates and moves many miles away from it's parent land mass you will possibly split apart a species that lived in the vicinity. Geographic isolation ensues and any mutations that happen in the two populations now statistically vary and can not enter a common gene pool, but enter each separate gene pool. This can cause allele frequencies to change in the separate gene pools, among other processes, to begin new species.
