The Morlocks are fictional creatures from H.G. Wells' science fiction novel, The Time Machine. They are depicted as a subterranean species that evolved from humans, living underground in a dystopian future. Morlocks are characterized by their ape-like appearance, pale skin, and nocturnal habits, emerging at night to hunt and scavenge. In the story, the Morlocks represent the darker side of human evolution and societal division. They contrast with the Eloi, another group of future humans who live above ground in a seemingly utopian society. This division highlights themes of class struggle and the consequences of technological advancement.
