On September 2, 2006, 5 friends on the Gaming Steve forum were inspired by the then-upcoming game Spore to evolve their own alien ecosystem using art, and thus created Sagan 4. As time went on, more people joined the team, and by the present day, over 100 participants have collectively contributed thousands of species to the ongoing ecosystem, creating a diverse array of fauna, flora, and more all descended from a single cell by building on one another's ideas through speculative evolution.
In 2016 the project went on hiatus, as the wiki was thought lost along with the archive of the submitted organisms. Fans of the project in 2019 created a revival of the project, dubbed Sagan 4 Beta, following a separate timeline that branched in early history. The original project was recovered in 2020 and relaunched under the new name Sagan 4 Alpha, and now both projects coexist as a shared community.
The Sagan 4 project now has it’s own website, forum, and wiki page. The team has grown to include other artists and the life on Sagan 4 keeps evolving and changing. The website, forum and wiki are hosted and maintained by MNIDJM.
