- The document discusses applying theories of evolution like Lamarck and Darwin to navigation patterns on the web. It suggests treating different navigation options as variations that face selective pressures from users. - The author proposes introducing randomness and "serendipity" into navigation, similar to random mutations in biology, and observing which options users prefer through their behavior. Successful patterns would be reinforced while less successful ones would disappear. - Implementing an "evolutionary" approach could help generate new navigation ideas and drive innovation, as small iterative changes based on user feedback are less risky than large overhauls. The competitive pressures of natural selection may help identify the most effective designs.
