First published in 1880, this study of the biology and geography of islands investigates some of the most pressing questions of nineteenth-century natural science. Why do countries as far-flung as Britain and Japan share similar flora and fauna when those of neighbouring islands in Malaysia are utterly unalike? What is the origin of life in New Zealand? And why do the geological formations of Scotland and Wales appear to be the result of glaciers when those countries lie in the temperate zone?

First published in 1880, this study of the biology and geography of islands investigates some of the most pressing questions of nineteenth-century natural science. Why do countries as far-flung as Britain and Japan share similar flora and fauna when those of neighbouring islands in Malaysia are utterly unalike? What is the origin of life in New Zealand? And why do the geological formations of Scotland and Wales appear to be the result of glaciers when those countries lie in the temperate zone? Dismissing popular theories of submerged continents and 'special creation', Alfred Russel Wallace (1823-1913) presents extensive evidence of the mass migration of species, and of drastic and repeated climatic changes across the globe. Drawing on a vast range of sources and the newest ocean soundings to support his theories, Wallace wrote the text for the intelligent general reader. It remains a fascinating introduction to the subject matter today.
Alfred Russel Wallace was an English naturalist, explorer, geographer, anthropologist, biologist, and illustrator who lived from 8 January 1823 to 7 November 1913. His own development of the theory of evolution through natural selection is what made him most famous. Charles Darwin's earlier papers on the subject were also excerpted in his 1858 paper, which was published in the same year. In response, Darwin rapidly wrote an abstract of the "great species book" he was composing, which he then published in 1859 as "On the Origin of Species. Beginning in the Amazon River basin, Wallace conducted considerable fieldwork. The Wallace Line, which divides the Indonesian archipelago into two distinct parts and is now known as the Wallace Line, was discovered by him while conducting fieldwork in the Malay Archipelago. In the western portion, where the animals are large and of Asian origin, and in the eastern portion, where the fauna reflects Australasia. He is frequently referred to as the "father of biogeography," or more specifically, of zoogeography, and was thought to be the foremost authority on the geographic distribution of animal species in the 19th century.
