Sagan 4 Alpha Wiki

Sagan 4 is an alien ecosystem project originally founded in 2006 by 5 friends led by Hydromancerx who were inspired by the then-upcoming game Spore. As time went on, more people joined the team, and by the present day, 118 participants have collectively contributed 5,784 species descending from a single cell to the ongoing ecosystem out of a love for art, speculative evolution, and xenobiology.
Sagan 4 is proudly the oldest ongoing and biggest overall evolution game (or evo game) on the internet. It is also one of if not the largest speculative evolution projects ever created. If you want to help us defend these titles, please consider joining us or spreading the word.

Life on Sagan 4
Introduction
Sagan 4 is a planet with conditions similar to Earth. All of its life derives from a single cell, Protosagania. Its major kingdoms are:
- Binucleozoa, an incredibly diverse group in which each cell has two or more nuclei, ranging from fish-like descendants, to insectoid-like fauna to the a wide range of Crystal Flora
- Carpozoa, fauna with wide ranging morphological differences thanks to genomic instability and a tendency towards Earth-like faunal forms
- Mancerxa, the largest kingdom, with a diverse range of fauna descended from green, photosynthesizing ancestors
- Phoenophyta, purple photosynthesizers that include clouds of microbes in the oceans and some of the first flora on land.
...and plenty more! Feel free to dig through the current Ecosystem Page to see all of the intact species and environments, or through our species search engine to find anything in particular that interests you.
