Alfred Russel Wallace and the Darwinian Species Concept: His Paper on the Swallowtail Butterflies (Papilionidae) of 1865
Soon after his return from the Malay Archipelago, Alfred Russel Wallace published one of his most signifcant papers. The paper used butterfies of the family Papilionidae as a model system for testing evolutionary hypotheses, and included a revision of the Papilionidae of the region, as well as the d...
