Concept explainers
To determine: The biogeographic realm that has been separated from the other biogeographic realms for the longest period.
Introduction: The study of the earlier and current geographic distribution of plants and animals is called biogeography. It includes origin of patterns, origin of population, how they got there and when. According to the principle of biogeography, each species are originated only once from its center of origin. From this center of origin, all species spread until a barrier prevents them. The range of species is defined as the portion of the Earth in which it is found.
To determine: The animals that characterize Australian realm.
