Quizplus · Accepted Answer

The fusion of Australia and Asia would create a land bridge which would allow species to cross over from one region to another, resulting in an exchange of species between the two regions. This would potentially lead to the formation of new species and a mixing of flora and fauna from previously distinct biogeographic regions.
