(Few writers describe a biodiverse Mars.) In science fiction, Martians are stereotypically imagined in one or more of the following ways: as alien invaders; as humanoids with a civilization that resembles one on Earth; as anthropomorphic animals; as beings with superhuman abilities; as humanoids with a lower intelligence than humans; as human colonists who adopt a Martian identity; and/or as an extinct race who possessed high intelligence. In Heinlein's 1956 novel Double Star, humans have colonized the solar system, and a politician on Mars faces the civil rights issue of granting a native Martian species (who are second-class citizens) the right to vote.	./cache/en-wikipedia-org-7272.html	./txt/en-wikipedia-org-7272.txt
