"The Man Who Evolved" is a science fiction short story by American writer Edmond Hamilton, first published in the April 1931 issue of Wonder Stories. In his comments on the story in Before the Golden Age, Isaac Asimov called it the first science fiction short story (as opposed to novel) that impressed him so much it stayed in his mind permanently. In her introduction to The Best of Edmond Hamilton, Leigh Brackett called the story "a fine example of Hamilton's skill in encapsulating an enormous theme into the neat and perfect compass of a short story".
