Speciation is the process by which co-existing daughter species evolve from one ancestral species - e.g., humans, chimpanzees, and gorillas arising from a common ancestor around 5,000,000 years ago. However, many questions about speciation remain controversial. The Birds of Northern Melanesia provides by far the most comprehensive study yet available of a rich fauna, composed of the 195 breeding land and fresh-water bird species of the Bismarck and Solomon Archipelagoes east of New Guinea. This avifauna offers decisive advantages for understanding speciation, and includes famous examples of geographic variation discussed in textbooks of evolutionary biology. The book results from 30 years of collaboration between the evolutionary biologist Ernst Mayr and the ecologist Jared Diamond. It shows how Northern Melanesian bird distributions provide snapshots of all stages in speciation, from the earliest (widely distributed species without geographic variation) to the last (closelyrelated, reproductively isolated species occurring sympatrically and segregating ecologically). The presentation emphasizes the wide diversity of speciation outcomes, steering a middle course between one-model-fits-all simplification and ungeneralizable species accounts. Questions illuminated include why some species are much more prone to speciate than others, why some water barriers are much more effective at promoting speciation than others, and whether hypothesized taxon cycles, faunal dominance, and legacies of Pleistocene land bridges are real. These years of study have resulted in a huge database, complete with distributions of all 195 species on 76 islands, together with their taxonomy, colonization routes, ecological attributes, abundance, and overwater dispersal. Color plates depict 88 species and allospecies, many of which have never been seen before. For students of speciation, Northern Melanesian birds now constitute a model system against which other biotas can be compared. For population biologists interested in other problems besides speciation, this rich database can now be mined for insights.

‘I know no place where firm and paternal government would sooner produce beneficial results then in the Solomons … Here is an object worthy indeed the devotion of one’s life’. Charles Morris Woodford devoted his working life to pursuing this dream, becoming the first British Resident Commissioner in 1897 and remaining in office until 1915, establishing the colonial state almost singlehandedly. His career in the Pacific extended beyond the Solomon Islands. He worked briefly for the Western Pacific High Commission in Fiji, was a temporary consul in Samoa, and travelled as a Government Agent on a small labour vessel returning indentured workers to the Gilbert Islands. As an independent naturalist he made three successful expeditions to the islands, and even climbed Mt Popomanaseu, the highest mountain in Guadalcanal. However, his natural history collection of over 20,000 specimens, held by the British Museum of Natural History, has not been comprehensively examined. The British Solomon Islands Protectorate was established in order to control the Pacific Labour Trade and to counter possible expansion by French and German colonialists. It remaining an impoverished, largely neglected protectorate in the Western Pacific whose economic importance was large-scale copra production, with its copra considered the second-worst in the world. This book is a study of Woodford, the man, and what drove his desire to establish a colonial protectorate in the Solomon Islands. In doing so, it also addresses ongoing issues: not so much why the independent state broke down, but how imperfectly it was put together in the first place.
