Alfred Russell Wallace Series

This British naturalist and explorer is renowned for independently proposing the theory of natural selection, which prompted Charles Darwin to publish his own findings. Wallace's extensive fieldwork in the Amazon basin and the Malay Archipelago led to his identification of the Wallace Line, a biogeographical boundary, solidifying his status as the "father of biogeography." Beyond co-discovering natural selection, he contributed to evolutionary theory with concepts like warning coloration and the Wallace effect, proposing how natural selection fosters speciation. Wallace was also a visionary, advocating for spiritualism, critiquing social injustice, and serving as one of the first scientists to raise concerns about environmental impacts.
