This paper, written by Wallace at Sarawak in Borneo in February of 1855 and published in Volume 16 (2nd Series) of the Annals and Magazine of Natural History in September 1855, conveys Wallace’s first formal statement of his understanding—a pre-natural selection understanding—of the process of biological evolution. It is also considered a landmark study in the development of the field of biogeography. Original pagination indicated within double brackets—and note that this transcription is taken from the original 1855 work, not the slightly enhanced version that was included in the collection Contributions to the Theory of Natural Selection in 1870.
