Biogeography Comes of Age

From Alfred Russel Wallace (1876), The Geographical Distribution of Animals
(London: Macmillian and Co.). After seperating the Oriental and Austrailan faunal regions
by what came to be known as the Wallace Line, Wallace proceeded with this finer
classification of the latter on the basis of the distribution of species of mammals, birds,
reptiles, amphibia, fishes, molluscs and insects.
