Informationen zum Autor 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. Klappentext First published in 1880, this wide-ranging study of island life addresses important questions of nineteenth-century biology and geography. Zusammenfassung A friend and correspondent of Charles Darwin, Alfred Russel Wallace (1823–1913) was an eminent naturalist and evolutionary theorist. In this study of the flora and fauna of islands, first published in 1880, he explores some of the earliest evidence of massive climate change, and investigates the migration of species.
