The Red Queen is a theory used to describe evolutionary adaptations. It was described as a phenomenon in which organisms must evolve at a furious pace merely to keep the ecological balance. This is because each organism adapts to the challenges facing it, and any organism directly impacted by this change must evolve as well. The theory is named after the Red Queen in Alice in Wonderland, who informs the titular protagonist that she must run as fast as she can merely stay in place. Ian Malcom postulates this theory as one reason why the dinosaurs have not consumed all the available vegetation on the Isla Sorna.
