Red Queen effect
Red Queen effect An evolutionary principle, first proposed in 1973 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
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.
