## Explanation

Themes of biological and cultural evolution are central, as seen in the Ortolians' engineered rise from canine companions to a sentient race, and the Thessians' adaptation to high-gravity worlds, showing how environments shape civilizations.

The Ortolians' rapid evolution from dogs to an intelligent race, guided by the Ancient Masters, highlights adaptation in the face of catastrophe.

Evolution and Adaptation is one of the patterns Invaders from the Infinite by John W. Campbell returns to. The chapter notes above are from this edition’s companions — open those chapters to see how the book stages the idea rather than treating the theme as a slogan.
