Biogeography is used as evidence for evolution and refers to the study of the distribution of organisms.

The background behind the  separation of Earth’s continents

The Earth’s continent have not always been separated as they are now, once upon a time they were all joined together in one large land mass known as Pangea. Approximately 180 million years this land mass began to break apart. The division saw two large continents formed the northern hemisphere known as Laurasia and the Southern hemisphere known as Gondwana. Approximately 60 million years ago these two continents started to further divide. Fossils and characteristic species in particular parts of the world provide evidence of continental drift. The presence of animals and plants with similar structural adaptations in the different continents demonstrates that continental drift is an example of convergent evolution.
