Alfred Russel Wallace

Alfred Russel Wallace (1823-1913) was a British naturalist, explorer, and biologist, best known for independently formulating the theory of evolution through natural selection, a concept he presented alongside Charles Darwin. His extensive travels in the Amazon and the Malay Archipelago provided him with rich insights into biodiversity and biogeography, which he documented in works such as "A Narrative of Travels on the Amazon and Rio Negro." Wallace also contributed to various fields, including entomology and anthropology, and was an advocate for spiritualism later in life, as reflected in his book "A Defence of Modern Spiritualism." His legacy endures in the realms of science and literature, marking him as a pivotal figure in the history of evolutionary thought.
