What is Sagan 4?
Sagan 4 is an alien planet ecosystem speculative evolution project originally started by Hydromancerx who was inspired by Carl Sagan’s video. It started on the Gaming Steve forum (Sept 2, 2006) as a project with a few hand selected artists. They were given a single cell organism called Protosagania to start with and challenged to evolve it into other forms of life. Sagan 4 is now populated with many species of flora and fauna all created by artists who love drawing and evolving creatures. Some of the life that has evolved has been Purple floras, Plents, Iron-based fauna, and so much more.
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. 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.
