"The Malay Archipelago" is perhaps the most celebrated of all writings on Indonesia. Attracting huge public interest at the time of publication, this two-part work ranks with the nineteenth century's most important travel writing and Wallace's name continues to be inextricably linked to the area. Wallace was best known for his discovery and description of the faunal discontinuity that now bears his name, "Wallace's Line," extending between the islands of Bali and Lombok and Borneo and Sulawesi, described here in "The Malay Archipelago," This led to his theory of natural selection, which was presented to the Linnaean Society in 1858.
