He postulated that there is an imaginary line separating Australis and Asiatic  animals. Wallace held a research about the spread of Indonesia animals and the result was that there are difference between animals on the Eastern and Western part of Indonesia.

Wallace line is a hypothetical line separating Asia and Australasia  geographic animals. The western part is related to Asia species, while on the east related to Australia species. This line passes Malay archipelago, between Borneo and Sulawesi, and between Bali and Lombok and Timor. Having typical animals (especially Sulawesi Island), different than oriental and Australia animals such as : Anoa, mako bird, and black monkey. The different was recorded by Antonio Pigafetta about the biological difference between the Phillipines and Maluku Islands, as recorded by Ferdinand Magellan in 1521. This line then was revised and moved eastward (Sulawesi land) by Webber. The flora and fauna of Asia then determined differently, according to flora and fauna types. This line is then called as ‘Wallace-Webber’
