Part 4/11:
Biological evolution is deeply intertwined with the energy available within an ecosystem. As noted, complex organisms—those capable of developing intelligence—require significant energy sources to sustain their existence. The argument asserts that planets with insufficient energy flux may not support the evolutionary arms race necessary for intelligence to emerge. For instance, while microbial life might exist in extreme or energy-poor environments, the likelihood of it evolving into a technologically advanced civilization is considerably lower.
