Wallace’s Line is a faunal boundary line drawn in 1859 by Alfred Russel Wallace that separates the biogeographical realms of Asia and Wallacea, a transitional zone. It passes through the Indonesian archipelago. Weber’s Line, proposed by Max Carl Wilhelm Weber, runs slightly east of Wallace’s Line and is considered the boundary where the fauna is approximately 50% Asian and 50% Australian in origin. The islands situated between these two lines are part of Wallacea.
