Human evolution

The novel also suggests a potential future for human evolution and perhaps a warning against overvaluing intelligence against more human qualities. The Narrator describes the Martians as having evolved an overdeveloped brain, which has left them with cumbersome bodies, with increased intelligence, but a diminished ability to use their emotions, something Wells attributes to bodily function.

The Narrator refers to an 1893 publication suggesting that the evolution of the human brain might outstrip the development of the body, and organs such as the stomach, nose, teeth, and hair would wither, leaving humans as thinking machines, needing mechanical devices much like the Tripod fighting machines, to be able to interact with their environment. This publication is probably Wells's own "The Man of the Year Million", first published in The Pall Mall Gazette on 6 November 1893, which suggests similar ideas.
