Dougal Dixon — Green World

1. Introduction Dougal Dixon is a Scottish paleontologist, geologist, and author credited as the father of modern speculative evolution (“spec evo”). His concept of a “Green World” is not a single, static place but a recurring theme across his works: a future or alternate Earth where flora has reasserted dominance, often in the absence of, or in response to, human influence or major climatic shifts. The phrase evokes a planet covered in dense, re-evolved ecosystems where animals have adapted to a world of overwhelming vegetation.
