Red Queen effect An evolutionary principle, first proposed by L. Van Valen, that much of the evolution of a lineage consists simply of keeping up with environmental changes (mainly, tracking a deteriorating environment), rather than occupying or adapting to new environments. The name is derived from the Red Queen, in Lewis Carroll's Alice Through the Looking-Glass, who had to run as fast as she could just to stay in the same place. See also ROMER's RULE.
