Notice how both evolve in tandem. If one evolves faster, the other must keep up to survive. This leads to constant improvements in both capabilities, even if their relative positions may remain unchanged (Red Queen Hypothesis).
Summary
Discusses coevolution and 'arms races'. The interaction between predators and prey drives an increase in complexity, though this doesn't necessarily mean long-term progress - sometimes it's just to maintain survival.
