Although Crichton uses plenty of Chaos Theory buzz words, "Red Queen" is not
one of them.  It comes from the evolutionary theory proposed by
paleomammalogist Leigh Van Valen back in the 1970s.  A WHOLE lot of
paleontological studies (neontological, too) back in the 1970s and early
1980s were concerned with validating or rejecting the Red Queen model.

(The reference comes from the Red Queen in _Through the Looking Glass_, who
must always run to keep in the same place.)
