Wallace and Darwin did not agree on everything. British naturalist, Alfred Wallace co-developed the theory of natural selection and evolution with Charles Darwin, who is most often credited with the idea. When he received Wallace’s essay, Darwin passed it to the geologist Charles Lyell and botanist Joseph Hooker, with whom he had previously discussed his own ideas of evolution by natural selection.
