The Wallace Line

Wallace proposed a theory of evolution at the same time as Darwin, but his contribution to the science of evolution remains less celebrated. The Wallace line is a boundary proposed in 1859 by Wallace to separate the biogeographical realms of SE Asia and Australia. To the west of the Line are found organisms related to Asiatic species; to the east, a mixture of species of Asian and Australian origins exist.
