Alfred Russel Wallace
modernEvolutionary Naturalism / Spiritualist Teleology1823 – 1913
Alfred Russel Wallace (1823–1913) was a British naturalist and co-discoverer of the theory of evolution by natural selection, having independently formulated the mechanism concurrently with Charles Darwin. Beyond biology, he made foundational contributions to biogeography and later developed a distinctive position holding that natural selection was insufficient to account for the higher mental and moral faculties of humans, pointing instead toward guided or teleological processes in nature.
