Alfred Russel Wallace was a British naturalist, explorer, and biologist who independently developed a theory of evolution by natural selection around the same time as Charles Darwin. He studied how animals and plants change over time to adapt to their environments, which helped explain how species evolve. Wallace carried out much of his research in the Malay Archipelago (now Indonesia and Malaysia), where he observed many different species and their variations. His findings made a significant contribution to the theory of evolution and helped shape modern biology, making him an important figure alongside Darwin in the history of science.
