Wallace's work in biogeography founded the science, highlighting global animal distribution patterns and laying groundwork for biodiversity studies.
Deep dives
Alfred Russel Wallace's Independent Theory of Evolution
Alfred Russel Wallace, a contemporary of Charles Darwin, developed a theory of evolution independently by proposing the idea of natural selection. Wallace was a self-taught biologist who collected vast numbers of animals and plants during his travels in the 19th century. His theory, similar to Darwin's but with key differences, highlighted the struggle for existence and environmental change driving evolution. Wallace emphasized geographical distribution and speciation occurring through geographical separation, which differed from Darwin's principles of competition and sympatric speciation.
Wallace's Zoological Geography Contribution
Wallace's book on the geographical distribution of animals, published in 1876, established him as the founder of biogeography. The book delves into zoological geography and geographical zoology, showcasing different zoological regions and the distribution of animal families globally. Despite not being aware of modern geological concepts like continental drift, Wallace's work detailed the patterns of animal distributions, laying the foundation for understanding biodiversity and the evolution of species.
Wallace's Eclipse in Evolutionary Recognition
Wallace faced a decline in recognition as an evolutionary scientist during the Eclipse of Darwinism, a period where the significance of natural selection waned until the mid-20th century. Darwin's prominence overshadowed Wallace's contributions, leading to a diminished reputation in evolutionary circles. However, Wallace's pioneering work in developing independent evolutionary theory and biogeography remains crucial in understanding the diverse mechanisms of species evolution and distribution.
Melvyn Bragg and his guests discuss the work of Alfred Russel Wallace, a pioneer of evolutionary theory. Born in 1823, Wallace travelled extensively, charting the distribution of animal species throughout the world. This fieldwork in the Amazon and later the Malay Archipelago led him to formulate a theory of evolution through natural selection. In 1858 he sent the paper he wrote on the subject to Charles Darwin, who was spurred into the writing and publication of his own masterpiece On the Origin of Species. Wallace was also the founder of the science of biogeography and made important discoveries about the nature of animal coloration. But despite his visionary work, Wallace has been overshadowed by the greater fame of his contemporary Darwin.
