Discovering Darwin

Alfred Russel Wallace (1823-1913) was a naturalist and biogeographer who co-founded the principle of Natural Selection with Darwin. Unlike Darwin, Wallace came from a working class family, had limited formal education, and started out as a paid collector of exotic specimens from South America and Southeast Asia. It was during a malarial illness in Ternate, the Molluccas Islands, that he came upon the idea of the role of natural selection in bringing about descendant species from parent species. On June 18, 1858, he put his ideas down in a short paper that he enclosed in a letter to Darwin that prompted Darwin to begin finally writing On the Origin of Species.
