Biogeography is a field of study focused on how species have changed over its evolutionary history regarding its distribution and geographical localization. Biogeography particularly examines biological diversity patterns. The evidence of evolution between the ostrich and the emu populations is of biogeographical type, since they are located in different regions but they are exposed to similar habitats.
