Evolving an Alien Civilization on a World Without Trees | Astrobiology Series

Could an advanced civilization evolve on a planet where trees and wood never existed? In this speculative astrobiology episode, Dr. Dakotah Tyler constructs a rocky super-Earth with stronger gravity, widespread volcanic activity, and immense crystal formations that function ecologically like forests. A six-limbed aquatic species gradually moves onto land and evolves the dexterity, spatial reasoning, memory, and problem-solving abilities needed to survive inside this dangerous three-dimensional environment. Expect to learn why trees were so important to human evolution, why intelligent marine animals have not developed technological civilizations, and how evolution repurposes traits that originally evolved for survival. The imagined hexapods eventually learn to manipulate light, ignite fires without wood, excavate crystal cities, harness electrical properties, and develop advanced optics and astronomy. This is not a prediction of what aliens must look like. It is a scientifically grounded world-building experiment exploring one plausible path to intelligence and civilization on a world very different from Earth. Hosted by Dr. Dakotah Tyler. Lead with curiosity.
