Alfred Russel Wallace [SEP] Introduction
Alfred Russel Wallace (8 January 18237 November 1913) was a British naturalist, explorer, geographer, anthropologist, biologist and illustrator. He is best known for independently conceiving the theory of evolution through natural selection; his paper on the subject was jointly published with some of Charles Darwin's writings in 1858." "This prompted Darwin to publish "On the Origin of Species". Like Darwin, Wallace did extensive fieldwork; first in the Amazon River basin, and then in the Malay Archipelago, where he identified the faunal divide now termed the Wallace Line, which separates the Indonesian archipelago into two distinct parts: a western portion in which the animals are largely of Asian origin, and an eastern portion where the fauna reflect Australasia.
