Evolved Animals is a term from Red Dwarf the Roleplaying Game. Inspired by the existence of The Cat and his people from the television and novel series, as well as the existence of The Dog from the episode "Parallel Universe", the game's creators extrapolated the potential existence of other humanoid races that might have evolved from creatures brought aboard Red Dwarf, or similar ships, and then left to evolve on their own for three million years. For details on "Evolved Cats", please see the pages for The Cat and Felis sapiens .
