The British naturalist Alfred Russel Wallace
(1823-1913) is best known for independently proposing a theory of evolution
due to natural selection that prompted Charles Darwin to publish his own
theory. Wallace worked extensively in the field, first in the Amazon
River basin and then in the Malay Archipelago, where he identified the
ecological line (which came to be known as Wallace's Line) that
divides the Indonesian archipelago into two distinct parts, one in which
animals closely related to those of Australia are common, and one in which
the species are largely of Asian origin. He was considered the 19th
century's leading authority on the geographical distribution of animal
species and has been called the "father of biogeography".
