I discovered, way after it was created, the world of Serina. Everyone probably knows about it but if you don't , and want to see a masterpiece of a deep deep dive into speculative evolution, take a look. World gets seeded by various lifeforms from Earth, the only vertebrate being canaries and left to simmer until the end of the planet. Over the lifetime of the planet, creatures evolve, some of them even get stories! Use the side bar to go forward and back in time. I don't know how well known it is but it deserves a retro Hugo or something. #ScienceFiction #SpeculativeEvolution #WorldOfSerina https://sites.google.com/site/worldofserina/home
