In the twentieth century, it was found to coincide with a plate boundary, which indicated that no land bridge could ever have existed between the two continental landmasses it separates. Introduced in the book Island Life, it separates Bali and Lombock, and species to the west of it are related to Asiatic species while those east of it are related to Australian ones.
