Glossary: Wallace’s line
Hypothetical line, proposed by British naturalist Alfred Russel Wallace that marks the transitional boundary between the Oriental and Australian zoogeographical regions.
It passes between the islands of Borneo and Sulawesi to its northern limit, Bali and Lombok to the south.
To the west of the line organisms descended from Asiatic ancestors predominate, while to the east there exist species of both Asian and Australian origin.
