Geodispersal:

In the time predating the Late Miocene- Early Pliocene era, geographical changes in the area that is now the Amazon basin, specifically the Fitzcarrald Arch region, isolated the local ichthyofauna, leading to the current richness of more than 5,600 species in less than 0.002% of the world's total liquid water supply. The natural creation of geographical barriers isolated fish, and subsequently led to the high concentration of many different types of species over a large amount of time due to interbreeding between species.
