Greenworld is a speculative evolution work by Scottish geologist and writer Dougal Dixon, best known for pioneering the genre with After Man: A Zoology of the Future (1981). In Greenworld , Dixon shifts focus from future animals to an imagined alien ecosystem — a lush, Earth‑like planet dominated by plants, but where the animal analogues have evolved from botanical ancestors.
Greenworld is the only book in his series set on an exoplanet rather than an altered Earth. greenworld dougal dixon pdf
