In Michael Crichton's "The Lost World," the author emphasizes that human evolution largely stems from our ability to adapt through behavior rather than solely through biological changes. Innovation plays a critical role in how we respond to various challenges we face in our environment. This capacity to change our actions and behaviors is what drives our development as a species.

Crichton suggests that, unlike many other species, humans possess a unique trait: our ability to invent and implement new behavioral strategies. This adaptability allows us to thrive in diverse situations, showcasing the significance of behavioral evolution in shaping our existence and survival over time.
